What Do I Need to Know About Email Blacklists?

Understanding email blacklists is crucial for anyone managing email campaigns or handling business communication. Blacklists are databases maintained by Internet Service Providers (ISPs) and Email Service Providers (ESPs) that flag domains known to send spam or harmful content. If your domain ends up on a blacklist, your emails are likely to be classified as spam, severely impacting your deliverability.

Why Domains Get Blacklisted

Your domain might land on a blacklist due to:

  • Low Engagement Rates: If your emails consistently have low open and response rates, it can signal poor engagement, leading to blacklisting.

  • High Spam Reports: When a significant number of recipients mark your emails as spam, it raises a red flag with ISPs.

  • High Bounce Rates: Sending emails to many invalid addresses results in bounces, which can harm your sender reputation.

  • Spam Traps: These are inactive email addresses used specifically to catch spam. Sending emails to these addresses is a common reason for getting blacklisted.

  • Security Breaches: If your domain is compromised and used for spamming activities without your knowledge, it can end up on a blacklist.

Preventing Blacklisting

To prevent your domain from being blacklisted, adhere to best practices:

  • Maintain List Hygiene: Regularly clean your email list to remove inactive or invalid addresses.

  • Engage Your Audience: Craft compelling content that encourages opens and responses.

  • Use Authentication Protocols: Implement SPF, DKIM, and DMARC to authenticate your emails and prove their legitimacy.

  • Monitor Your Domain's Status with Revli: Revli, not only warms up your email but also continuously monitors your domain's status on various blacklists, helping you stay ahead of potential issues.

How to Get Delisted

If your domain is blacklisted, here are steps to get delisted:

  1. Wait it Out: Some blacklists have a policy of automatically removing domains after a certain period, usually 1-3 weeks, depending on the violation's severity.

  2. Submit a Removal Request: Visit the blacklist provider's website and complete a delisting request form. Provide details about the corrective actions you've taken and demonstrate your commitment to best email practices.

Regular Monitoring and Proactive Measures

Regularly monitoring your domain's status on blacklists is vital. Use tools like Revli to keep a check on your domain's health. This proactive approach allows you to quickly address any issues and maintain a robust email sending reputation.


Staying off email blacklists requires a combination of good email practices, audience engagement, technical safeguards, and regular monitoring. By understanding how blacklists work and taking proactive steps to maintain a healthy email reputation, you can ensure your emails consistently reach their intended recipients.
