Check comcast email blacklist

Comcast's email blacklist, also known as the "Spam Block List" or "SBL", is a list of email addresses or domains that have been identified as sending spam or unwanted emails. If your email address or domain is on this list, it may be blocked by Comcast's email servers, preventing you from sending emails to Comcast customers.

To check if your email address or domain is on Comcast's email blacklist, you can follow these steps:

  1. Go to the Comcast Email Blacklist Checker tool: https://www.comcast.net/emailblacklistchecker
  2. Enter your email address or domain in the provided field.
  3. Click the "Check" button.
  4. If your email address or domain is on the list, you will see a message indicating that it has been identified as spam or unwanted email.

If your email address or domain is on the list, you can try the following steps to get removed:

  1. Check your email content: Make sure that your email content is not spammy or unwanted. Avoid using spammy keywords, and ensure that your emails are relevant and valuable to your recipients.
  2. Verify your domain: Ensure that your domain is properly verified with Comcast. You can do this by following the instructions provided by Comcast.
  3. Contact Comcast support: Reach out to Comcast's support team and provide them with your email address or domain. They may be able to help you get removed from the list.
  4. Use a reputable email service provider: If you're using a third-party email service provider, ensure that it is reputable and follows best practices for email marketing.

Remember that being on Comcast's email blacklist is not the same as being on a global spam blacklist, such as the Spamhaus Block List (SBL). If you're experiencing issues with your email delivery, it's a good idea to check multiple blacklists to ensure that your email address or domain is not listed on any other blacklists.
