Deliverability Checklist Keep your Cold Emails Away from Spam

Learn how to boost email deliverability and keep your cold emails out of spam with this comprehensive checklist. Follow these steps before, during, and after sending cold emails for successful outreach.

In the world of digital communication, email remains a powerful tool for business outreach. However, successfully reaching your audience's inbox can be a challenging task, especially when sending cold emails. To ensure your messages land where they belong, you need to focus on email deliverability and avoid the dreaded spam folder. 

In this comprehensive guide, we will provide you with a step-by-step checklist to boost deliverability and keep your cold emails out of spam.

Before Sending Cold Emails

Step 1: Complete your technical setup

Before you even think about hitting that send button, it's crucial to ensure that your email infrastructure is properly configured. 

Here are the key elements to check:

SPF (Sender Policy Framework): Make sure your SPF record is correctly set up to authenticate your domain.

DKIM (DomainKeys Identified Mail): Implement DKIM to add another layer of authentication to your emails.

DMARC (Domain-based Message Authentication, Reporting, and Conformance): Set up DMARC to provide a policy for email authentication.

A solid technical setup lays the foundation for good email deliverability.

Step 2: Email warm-up

Sending a barrage of cold emails from a new domain or IP address is a surefire way to land in the spam folder. To avoid this, engage in email warm-up:

Start Slow: Begin by sending a small volume of emails and gradually increase it over time.

Engage Subscribers: Encourage recipients to open, reply, and engage with your emails. This signals to email providers that your messages are valuable.

Maintain Consistency: Stick to a consistent sending schedule to establish trust with email providers.

By warming up your email reputation, you'll improve your chances of getting your cold emails delivered successfully.

While Sending Cold Emails

Step 3: Write a personalized subject line

The subject line is your email's first impression, and personalization can make all the difference. Use the recipient's name, reference their company, or mention something specific to their industry. 

This not only increases open rates but also reduces the likelihood of your email being marked as spam.

Step 4: Use links instead of attachments

Attachments are often associated with spam emails. To enhance your deliverability, upload your files to a cloud storage service like Google Drive or Dropbox and share the link in your email. 

This practice ensures that your emails are less likely to trigger spam filters.

Step 5: Avoid using spam trigger words

Certain words and phrases are notorious for triggering spam filters. Be mindful of words like "free," "guarantee," "earn money," and excessive use of exclamation marks.

Craft your email content to sound professional and avoid language that could raise red flags.

After Sending Cold Emails

Step 6: Monitor your email deliverability

Your job doesn't end once you hit the send button. Regularly monitor your email deliverability to identify and rectify any issues. Use email tracking tools to check open rates, click-through rates, and bounce rates. 

If you notice a decline in deliverability, investigate the root cause and take corrective action promptly.

Step 7: Keep your email list clean

Maintaining a clean and engaged email list is vital for good deliverability. Remove bounced email addresses, unsubscribed recipients, and inactive subscribers regularly. 

This not only improves deliverability but also saves you from wasting resources on unresponsive contacts.

Step 8: Send follow-up emails

Following up is a crucial part of cold email outreach. It shows your persistence and commitment to building a connection. Craft polite and well-timed follow-up emails to remind recipients of your initial message.

This step can significantly improve your response rates and overall success.


In the realm of cold email outreach, deliverability is your ticket to success. By following this comprehensive checklist, you can significantly enhance your email deliverability and keep your cold emails out of the spam folder. 

Remember to complete your technical setup, engage in email warm-up, write personalized subject lines, use links instead of attachments, and avoid spam trigger words. After sending cold emails, monitor deliverability, maintain a clean email list, and send strategic follow-ups.

By implementing these steps, you'll not only increase the chances of your cold emails reaching their intended recipients but also improve your overall email marketing effectiveness. So, gear up, follow the checklist, and watch your cold email outreach soar to new heights!
