Are your cold emails ending up in spam, costing you potential clients? You’re not alone—nearly 85% of all emails are considered spam by filters (Statista).

But here’s the good news: achieving a 99% deliverability rate is possible with the right approach.

In this guide, we’ll explore to enhance your cold email deliverability, protect your sender reputation, and improve your business success.

What is Cold Email Deliverability?

Cold email deliverability refers to the ability of your emails to reach the recipient's inbox, not the spam folder. When you send a cold email, it should land directly in the recipient’s inbox, so they can see it and read it.

But many emails often get marked as spam. Understanding and improving deliverability can help you reach more people.

To increase engagement, make sure your cold emails land in the intended recipients' inboxes, not spam folders.

Why is Cold Email Deliverability Important?

1. Maximizes Your Outreach Efforts

  • When your emails reach the recipient’s inbox, more people can see your message. This means better chances for them to reply or take action.
  • If your emails land in the spam folder, your efforts are wasted. Email deliverability ensures that your hard work pays off.

2. Protects Your Sender Reputation

  • Sender reputation is like a score that shows how trustworthy your emails are. If your emails often get marked as spam, your score drops.
  • Internet service providers (ISPs) and email clients might block your future emails. Using good practices, like avoiding spam trigger words and setting up DomainKeys Identified Mail (DKIM), can protect your reputation.

3. Improves ROI on Email Campaigns

  • Better deliverability means more emails reaching intended recipients. This improves your return on investment (ROI) because you get more responses.
  • For example, businesses that maintain a clean email list see 25% higher engagement rates than those that don’t.

4. Improves Business Credibility

  • When your emails reach the recipient's inbox and don’t look spammy, it builds trust. People are more likely to open and read emails from senders they trust.
  • Including unsubscribe links and relevant content helps you appear more credible.

5. Increases Conversion Opportunities

  • High deliverability ensures more people see your offers. The more people who see your message, the more chances you have to convert them into customers.
  • With the right subject lines and engaging content, you can increase click-through rates and, eventually, sales.

12 Ways to Avoid Landing in Spam Folder

1. Use a Professional Email Address

When sending cold emails, always use a professional email address. Instead of a generic email like “john@gmail.com,” opt for “john@yourcompany.com.” This makes your emails look more credible.

Why It’s Important:

Professional email addresses are less likely to be flagged by spam filters. Email service providers view them as more trustworthy.

Using a business domain helps keep your email client sender reputation strong, which improves deliverability rates. Emails from generic addresses are often marked as spam by default.

How to Implement:

  • Set up an email address that matches your business domain. Check with your email service provider to ensure everything is properly configured.
  • Use a dedicated IP address to avoid any issues caused by sharing an IP with less reputable senders.

2. Avoid Spam Trigger Words

Some words can set off spam filters and get your emails blocked before they even reach the inbox. Words like “Free,” “Buy Now,” “Congratulations,” and “Limited Time Offer” are common examples.

Why It’s Important:

Avoiding these spammy words can greatly improve your mail server chances of reaching the primary inbox.

Spam filters are designed to protect recipients. Triggering these filters can lead to more spam complaints and hurt your sender score.

How to Implement:

  • Choose Your Words Wisely: Instead of using aggressive sales language, try more straightforward and personal wording. For example, instead of saying “Buy Now,” you can say “Check out our latest offer.”
  • Use Mail Tester Tools: Tools like GlockApps or MailTester can help scan your email content and flag any risky words.
  • Keep a Clean Email List: Ensure that your emails are reaching active, relevant recipients by avoiding outdated or unverified email addresses.

3. Use DomainKeys Identified Mail (DKIM)

DKIM is a way to make your emails more secure. It attaches a digital signature to your emails, verifying that they originate from your domain and remain unchanged.

Why It’s Important:

Email service providers like Gmail, Outlook, and Yahoo look for DKIM when determining if your email is legitimate. Having DKIM set up means they’re more likely to trust your emails.

It helps prevent phishing attacks by proving that your emails are genuinely from your own domain name. This keeps your email clients and recipients safe.

How to Implement:

  • Set Up DKIM: Work with your email provider to add DKIM to your domain’s DNS records. This may sound technical, but your provider can guide you step-by-step.
  • Monitor Your Sender Score: Check your sender reputation regularly using tools like Sender Score. A good reputation improves deliverability.
  • Use Other Authentication Protocols: Along with DKIM, set up Sender Policy Framework (SPF) and Domain-Based Message Authentication (DMARC). This strengthens your email security and helps emails pass through spam filters.

Domain Message Authentication Reporting (DMARC) helps monitor and protect your domain from unauthorized use by providing detailed reports on failed authentication attempts.


4. Write Personalized Content

Personalized content means crafting emails that feel like they’re written specifically for the recipient. Instead of generic, one-size-fits-all messages, write emails that address the person’s name, interests, or company needs.

Why It’s Important:

Personalized emails achieve 29% more opens and 41% higher click-through rates than generic ones, according to Experian.

Spam filters are more likely to flag generic, copy-paste content. Customized messages look more authentic and less spammy.

How to Implement:

  • Use Their Name: Always include the recipient’s name in the greeting. Instead of “Hi there,” write “Hi, John!”
  • Mention Their Company or Industry: Talk about their business or industry challenges. For example, “I noticed your company has been expanding, and I wanted to share how our service can support your growth.”
  • Use Email Marketing Tools: Platforms like Alore make it easy to add personalization tags, so your emails automatically adjust based on the recipient’s details.

5. Maintain a Clean Email List

A clean email list means having a list of active, engaged, email accounts and addresses. Remove addresses that don’t respond, bounce, or are invalid.

Why It’s Important:

By keeping your list clean, you avoid sending emails to people who might mark your messages as spam. A clean list means you’re reaching people who are more likely to respond, leading to better open and click-through rates.

How to Implement:

  • Regularly Clean Your List: Use tools like MailTester to scan and remove inactive or invalid emails. This helps maintain a healthy list.
  • Remove Inactive Subscribers: If a subscriber hasn’t opened your emails in six months, consider removing them from your list.
  • Use Double Opt-In: When someone signs up, ask them to confirm their subscription. This ensures you only add genuine recipients who want to receive your emails.

6. Warm Up Your Email Account with Alore

Warming up your email account means gradually increasing the number of emails you send over time. This helps build trust with email service providers.

Why It’s Important:

If you suddenly send 1,000 emails from a new account, email clients might see this as spam. Warming up your account shows that your sending habits are genuine.

Gradual sending patterns are less likely to trigger spam filters, ensuring more emails reach the recipient’s inbox.

Consistent, gradual sending improves the likelihood of your emails landing in the primary inbox, not the spam folder.

How to Implement:

  • Start Slow: Begin by sending a small number of emails (about 20-30 per day) and slowly increase over a few weeks.
  • Use Alore’s Warm-Up Feature: Alore helps automate the warm-up process by sending emails on your behalf and gradually increasing the volume. This makes it easier to build a positive sender reputation.
  • Monitor Your Email Performance: Keep an eye on open rates, bounce rates, and spam complaints. If you notice high bounce rates, pause and clean your email list.

7. Include an Easy Unsubscribe Option

An unsubscribe option is a small link at the bottom of your email that lets people opt out if they don’t want to receive more emails from you.

Why It’s Important:

Recipients are more likely to trust your emails if they see an easy way to unsubscribe. Without this option, your emails might get marked as spam.

Many countries, including the U.S. under the CAN-SPAM Act, require all marketing emails to have an unsubscribe link. Ignoring this can lead to penalties and harm your sender reputation.

Giving people the option to unsubscribe helps prevent them from marking your emails as spam. Too many spam complaints can damage your sender score and make it harder to reach the recipient’s inbox.

How to Implement:

  • Add a Clear, Simple Link: Place an “Unsubscribe” link at the bottom of every email. Make it visible and easy to click.
  • Use Email Service Providers: Most email service providers like MailChimp and Alore will automatically add an unsubscribe link for you.
  • Test the Link: Always test the unsubscribe link to ensure it works properly. It should lead to a quick and easy process for the user.

8. Balance Text and Images

Balancing text and images means making sure your emails aren’t overloaded with too much of either. Too many images can trigger spam filters, while too much text might bore the reader.

Why It’s Important:

Emails that have too many images or all-text formats often get flagged by spam filters. A balance helps your emails appear natural and trustworthy.

People are more likely to read and respond to an email that has a mix of engaging visuals and concise text. It keeps things interesting and easy to read.

Well-placed images and short, clear text can encourage readers to click on your links. This leads to higher engagement and better email deliverability.

How to Implement:

  • Use a 60/40 Text-Image Ratio: Aim for about 60% text and 40% images. This helps maintain a good balance.
  • Optimize Image Sizes: Large images can slow down your email’s loading time and lead to lower engagement. Compress images to make sure they load quickly.
  • Add Alt Text to Images: Alt text is a description of an image that shows up if the image doesn’t load. It helps improve the accessibility of your emails and provides context to the reader.

9. Keep Email Content Short and Relevant

Short, relevant content means writing emails that are straight to the point. Avoid long paragraphs and only include information that matters to the recipient.

Why It’s Important:

Long, rambling emails can trigger spam filters. Shorter emails are more likely to pass through these filters and reach the recipient’s inbox.

People are busy. They are more likely to read your email if they can quickly understand the message. Keep it short, relevant, and to the point.

When you keep the content relevant, recipients are more likely to respond, click on your links, and engage with your message.

How to Implement:

  • Focus on One Clear Message: Don’t try to cover everything in one email. Pick one main point and stick to it.
  • Use Bullet Points: Break up long blocks of text with bullet points. This makes it easier for the reader to scan and understand the key points.
  • Add a Clear Call to Action (CTA): End your email with a simple, direct CTA. Whether it’s “Sign Up Now,” “Learn More,” or “Reply to This Email,” make sure the recipient knows what to do next.

10. Monitor Your Email Reputation

Your email reputation is like a score that tells email service providers (like Gmail or Outlook) how trustworthy your emails are. If your score is low, your emails might end up in the spam folder.

Why It’s Important:

A strong email reputation increases the chances of your emails reaching the recipient’s inbox. If your reputation drops, service providers might block your emails entirely.

Email service providers (ESPs) monitor how often people mark your emails as spam or if you send to inactive subscribers. Maintaining a positive sender reputation helps build trust and improves your overall email deliverability.

How to Implement:

  • Check Your Sender Score Regularly: Use tools like Sender Score or MailTester to see how email providers view your reputation. A score of 80 or higher is generally considered good.
  • Avoid Sending to Inactive Subscribers: Remove addresses that don’t open your emails. Sending to too many inactive accounts can hurt your reputation.
  • Minimize Spam Complaints: Make sure your emails have a clear purpose, and always include an easy way to unsubscribe. This reduces the chances of recipients marking your emails as spam.

11. Avoid Overuse of Links

Including too many links in your email can make it look suspicious to spam filters. It may also make your email look cluttered and confusing to readers.

Why It’s Important:

Spam filters are designed to catch emails with too many links. They see it as a sign of spammy behavior, especially if the links don’t seem to match the content.

Fewer links make your email look cleaner and easier to read. It also encourages readers to focus on the main message and call to action (CTA).

How to Implement:

  • Limit Links to 1-2 Per Email: Make sure each email has a clear CTA and only include links that support that action. For example, if you want the recipient to visit your website, include just one link to your homepage.
  • Avoid Link Shorteners: Spam filters may see shortened links as a sign of phishing or spam. Always use full, clear URLs.
  • Use Relevant Links Only: If you need to include a link, make sure it is directly related to the content of your email. Irrelevant links can confuse readers and make them suspicious.

12. Check Your Email’s HTML Code

The HTML code in your email is what determines how it looks when it arrives in the recipient’s inbox. Poorly coded emails can trigger spam filters, especially if there are hidden elements, extra tags, or broken links.

Why It’s Important:

Clean HTML ensures your emails look the same whether they’re viewed on a computer, tablet, or smartphone. Broken or messy code might make your email look unprofessional or unreadable.

Some HTML elements, like hidden text or too many images, can cause spam filters to block your email. Clean, simple code helps your email pass through these filters smoothly.

How to Implement:

  • Use a Trusted Email Service Provider (ESP): Platforms like Alore or MailChimp automatically clean up your HTML and ensure it follows best practices.
  • Preview Your Emails Before Sending: Always check how your email looks across different devices and clients. Make sure links work, images load, and the layout is correct.
  • Remove Unnecessary Elements: Avoid extra tags, broken links, or hidden text. Keep your code simple to reduce the chances of triggering spam filters.

How to Craft Effective Subject Lines to Avoid Spam Filters

How to Craft Effective Subject Lines to Avoid Spam Filters
How to Craft Effective Subject Lines to Avoid Spam Filters

1. Keep It Short and Precise

Keeping your subject line short and to the point helps grab attention quickly. Long subject lines might get cut off, especially on mobile devices.

Why It’s Important:

Short subject lines perform better. Research shows that subject lines with 6-10 words have the highest open rates.

Spam filters are more likely to flag spam emails, with long, confusing subject lines. A short and clear subject line looks more professional and trustworthy.

How to Do It:

  • Limit Your Subject Line to 6-10 Words: Make sure your subject line is clear and gives a quick preview of what’s inside the email. For example, instead of “Here’s a Fantastic Offer You Won’t Want to Miss,” write “Limited Time Offer on Our Best Product.”
  • Focus on One Key Message: Think about what you want the recipient to know. Keep the subject line focused on that message, and don’t add unnecessary details.
  • Use Simple Language: Avoid complicated words. Make sure your subject line is easy to understand at first glance.

2. Avoid Using ALL CAPS or Excessive Punctuation!!!

Using ALL CAPS or too many exclamation marks makes your email look spammy and unprofessional. It can also make people feel like you’re shouting at them.

Why It’s Important:

Spam filters are designed to catch emails that look suspicious. Too much punctuation or capital letters often get flagged as spam.

Nobody likes getting emails that feel like they’re screaming. It can turn people off before they even read the email.

How to Do It:

  • Use Proper Capitalization: Only capitalize the first letter of the first word and any proper nouns. For example, instead of “HURRY!!! LIMITED TIME OFFER!!!,” write “Hurry—Limited Time Offer.”
  • Limit Punctuation: Use punctuation sparingly. One exclamation point is fine if it fits the tone, but don’t use more than one. Avoid symbols like “$” or “%” in the subject line unless necessary.
  • Write Like a Conversation: Think about how you would write to a friend. Use natural language, and avoid trying too hard to grab attention with exaggerated punctuation or CAPS.

3. Personalize the Subject Line

Personalizing the subject line means adding something specific to the recipient's mail server, like their name or company. Personalized emails are more likely to get opened because they feel like they’re meant just for the reader.

Why It’s Important:

Emails with personalized subject lines are 26% more likely to be opened, according to Campaign Monitor.

Personalization makes the recipient feel like you took the time to reach out to them specifically, which helps build trust.

How to Do It:

  • Add the Recipient’s Name or Company: Use the recipient’s name or their company name in the subject line. For example, instead of “Check Out Our New Service,” write “John, Discover How Our Service Can Help [Company Name].”
  • Use Email Tools: Many email marketing tools like Alore or MailChimp allow you to automatically insert names or other details into the subject line for each recipient.
  • Mention Something Relevant: If you know something about the recipient’s needs or interests, mention it. For example, “John, Boost Your Cold Email Deliverability Today.”

4. Use Action-Oriented Language

Action-oriented language encourages the recipient to take immediate action. Words like “get,” “start,” “discover,” or “save” can inspire readers to open your email.

Why It’s Important:

People are more likely to open emails that tell them what they can do or gain. Action verbs make your message clear and direct. Action-oriented words are less likely to trigger spam filters compared to vague or misleading phrases.

How to Do It:

  • Start with a Verb: Begin your subject line with a verb to tell the reader exactly what they can do. For example, “Discover How to Boost Your Sales” is more effective than “Information About Sales.”
  • Be Specific: Make sure the action matches the content of your email. If your email offers a discount, you might say, “Save 20% on Your Next Purchase.”
  • Avoid Misleading Words: Stay clear of words that could sound like spam triggers, such as “Free” or “Click Here Now.” Use genuine, specific action words.

5. Ask a Question

Asking a question in your subject line can make people curious. It engages them and makes them think about the answer, which increases the chances of them opening the email.

Why It’s Important:

Questions invite readers to think and respond, making them more likely to engage with your email. When you ask a question, it feels more personal. It can make the recipient feel like you’re talking directly to them.

How to Do It:

  • Use Simple Questions: Ask questions that are easy to understand and relevant to your audience. For example, “Want to Improve Your Email Deliverability?” is simple and clear.
  • Be Relevant to Your Audience: Make sure the question relates to the recipient’s interests or needs. For instance, if your target audience struggles with cold emails, try, “Tired of Your Cold Emails Landing in Spam?”
  • Avoid Overusing Questions: While questions can be engaging, using them too often can feel repetitive. Balance questions with other types of subject lines.

6. Add Numbers When Relevant

Including numbers in your subject line, like “5 Tips” or “10 Ways,” can make your email look more organized. It tells readers exactly what to expect and helps them process information quickly.

Why It’s Important:

Numbers make your subject line clear. Readers know that your email will offer easy-to-read, structured content. Emails with numbers can draw attention because they stand out from typical text-based subject lines.

How to Do It:

  • Use Specific Numbers: Instead of saying “Many Tips to Improve Cold Email Deliverability,” try “7 Proven Tips to Improve Cold Email Deliverability.” Being specific makes the content look more valuable.
  • Choose Odd Numbers for Better Engagement: Studies show that subject lines with odd numbers tend to perform better. For example, “5 Strategies” might catch the eye more than “4 Strategies.”
  • Combine Numbers with Action Verbs: Pairing numbers with action-oriented words makes your subject line even stronger. For instance, “Learn 5 Ways to Avoid Spam Filters” is engaging and direct.

7. Create a Sense of Urgency (Without Overdoing It)

A sense of urgency in your subject line encourages people to act quickly. For example, phrases like “Last Chance” or “Only 24 Hours Left” make readers feel they might miss out if they don’t open the email.

Why It’s Important:

Urgent language pushes recipients to act quickly. When done carefully, urgency works without looking spammy. But overusing it, like saying “ACT NOW!!!” can trigger spam filters.

How to Do It:

  • Be Clear and Honest: Make sure your urgency is real. For instance, if your sale ends in 24 hours, mention it. Avoid using phrases like “limited offer” if it’s not true.
  • Limit the Use of Punctuation: Avoid excessive punctuation like “Hurry Up!!!” Stick to simple phrases like “Ends Tonight: 50% Off.”
  • Use Time-Related Words: Words like “Today,” “Now,” and “Ends Soon” create urgency without appearing desperate.

8. Include Relevant Emojis (If Appropriate)

Emojis can add a fun touch to your subject line and make it stand out. However, you should only use emojis when they match the tone of your message and audience.

Why It’s Important:

With hundreds of emails, an emoji can help yours pop out. For example, a little 💸 next to “Save Big This Weekend” draws attention.

Emojis can make your email feel more friendly and relatable. But they should be used sparingly to avoid looking unprofessional or spammy.

How to Do It:

  • Choose One or Two Emojis That Match Your Message: Pick emojis that add to the message, like 🕒 for a limited-time offer or 🎉 for a celebration.
  • Don’t Overuse: One emoji is often enough. Too many can make your email look untrustworthy. For example, “Get Free Gifts 🎁” is better than “🎁🎁🎁 Get Free Gifts!!! 🎁🎁🎁.”
  • Test for Compatibility: Make sure the emoji appears correctly on different devices. Some emojis may not show up on older devices or certain email clients.

9. Mention a Mutual Connection or Benefit

Personalizing your subject line by mentioning a mutual connection or benefit can make the recipient more likely to open your email. It can be as simple as “John Suggested I Reach Out” or “How We Helped [Company Name] Save 30%.”

Why It’s Important:

When recipients see something familiar, they feel more comfortable opening the email. Mentioning a mutual connection can make the email feel more personal.

When you mention a specific benefit, the recipient can see how your email might help them. Emails that highlight a clear benefit get opened more often.

How to Do It:

  • Use the Recipient’s Name or a Company Name: If you know the person’s name or where they work, include it. For example, “John, Here’s How We Can Improve Your Email Deliverability.”
  • Mention a Shared Connection or Interest: If you have a mutual contact, use that to build credibility. For instance, “Sarah from ABC Corp Recommended I Contact You.”
  • Focus on the Benefit: Make sure your subject line answers “What’s in it for me?” For example, “Boost Your Email Deliverability by 20% in One Week.”

10. Limit Special Characters

Special characters include symbols like “!!!,” “$$$,” or “###.” These might catch attention, but they also make your email look like spam. Using too many of these can cause your email to end up in the spam folder.

Why It’s Important:

Spam filters are trained to look for excessive use of special characters. Emails with too many symbols can be marked as spam, even if they contain valuable content.

Subject lines with many symbols can seem untrustworthy or unprofessional. Keeping them simple helps build trust with the recipient.

How to Do It:

  • Keep It Simple: Use words instead of symbols. For example, write “Special Discount” instead of “$$$ Discount!!!”
  • Stick to Punctuation Marks: It’s okay to use simple punctuation like a period or comma. Just don’t overdo it with exclamation points.
  • Avoid Overuse: Even using one special character can make your subject line look spammy, so use them sparingly.

Advanced Email Deliverability Techniques

Advanced Email Deliverability Techniques
Advanced Email Deliverability Techniques

1. Implement BIMI (Brand Indicators for Message Identification)

BIMI helps your brand logo show up next to your email in the recipient's inbox. It makes your email look official and trustworthy. BIMI is an extra step of authentication that proves you are the real sender.

How to Do It:

  • Set Up Domain-Based Authentication: Make sure you have DomainKeys Identified Mail (DKIM), Sender Policy Framework (SPF), and Domain-based Message Authentication, Reporting & Conformance (DMARC) in place. These are necessary for BIMI to work.
  • Create a Verified Logo: Use your official logo and follow the BIMI guidelines. Once set up, your logo appears alongside your emails, making them stand out and look professional.

Using email deliverability best practices, like setting up SPF and DKIM, ensures better inbox placement.


2. Use Dedicated IP Addresses

A dedicated IP address is an IP that is only used by your email campaigns. Unlike shared IPs, no one else is sending emails from it. This gives you better control over your email servers and sender reputation.

How to Do It:

  • Ask Your Email Service Provider: Check if they offer dedicated IP addresses. It might cost extra, but it can be worth it.
  • Warm Up Your IP: Don’t start sending a lot of emails from a new IP right away. Start slow, and increase the volume gradually. This helps build a positive sender reputation and avoids triggering spam filters.

3. Set Up Automated Engagement Campaigns

Engagement campaigns involve sending follow-up emails based on how recipients interact with your messages.

This keeps your audience engaged and shows email clients (like Gmail or Outlook) that your emails are important.

How to Do It:

  • Segment Your Audience: Divide your email list based on engagement. For example, you can send a different follow-up to someone who opens your emails versus someone who doesn’t.
  • Use Automation Tools: Tools like Mailchimp or ActiveCampaign can help you set up these automated campaigns. These tools make it easier to send the right message to the right person at the right time.

4. Monitor Blacklists Regularly

A blacklist is a list of IP addresses or domains that are blocked by internet service providers (ISPs). If sending ip address of your email server is on one, your emails might not reach the recipient's inbox.

How to do it:

  • Check weekly: Use tools like Spamhaus or MXToolbox to see if your IP address or domain is blacklisted.
  • Act fast: If you find your address on a blacklist, follow the removal steps provided by the listing service.
  • Keep your lists clean: Avoid spam complaints by sending emails only to engaged, active recipients.

5. Optimize Sending Cadence

Sending cadence is how often you send emails. It could be daily, weekly, or monthly.

How to do it:

  • Start slow: If you're starting a new campaign, begin with a few emails. Gradually increase the volume. This keeps your sender reputation positive.
  • Analyze responses: Check open rates and click-through rates. If you see a drop, your cadence might be too high. Adjust accordingly.
  • Segment your audience: Not everyone needs emails at the same time. Send targeted emails to groups based on their interests or past behavior.

6. Leverage AI-Powered Deliverability Tools

AI tools can help predict and improve email deliverability. They analyze data to suggest the best times to send emails, how often, and even which words to avoid.

How to do it:

  • Choose a tool: Some popular options include MailChimp's Smart Send Time and SendGrid's Email Testing. These tools help track email performance and suggest improvements.
  • Set up smart campaigns: Use AI to find the best time to send emails based on past results. This improves open rates.
  • Analyze feedback: Let AI tools review your email drafts. They can suggest ways to avoid spam filters by identifying risky keywords or phrases.
