Blacklist

 In

A blacklist is a discrete list of email senders who have previously sent spam emails to a user. It is a real-time database that checks whether an IP address is sending emails that could be considered spam. Such blacklists exist with a goal to reduce email spam and keep the email marketing environment clean.

If a lot of recipients are marking your emails as spam, there is a chance that your IP address might end up on a blacklist. It is important that once you discover that you’re on a blacklist, you take the required steps to remove your IP address from that list.

To remove yourself from a blacklist, you need to closely monitor spam rates and improve engagement rates of your campaigns. This can be done by allowing users to opt-in to campaigns and also by sending engaging content in emails that are neatly designed.

Here are some reasons why email addresses get blacklisted:

  1. If the email is sent from an unauthenticated email address it might bounce. This can be fixed by authenticating the sending domain or the server which is authorized to send emails on the sender’s behalf.
  2. If the content of the email has spam related content then the inbound email server will send it to the Spam folder. Spam filters look the email as a whole, if the email message doesn’t pass the criteria then it will be considered as Spam.
  3. If many receivers mark a certain senders emails as SPAM then the ISP will respond by blocking future emails by said sender. The email/IP address can be removed from the blacklist after a period of time.
