Summary:

What is email blacklist?

The email blacklist is a real-time updated database that identifies email addresses and IP addresses as spammers, due to unfair sending practices.

Thanks to these lists, email providers have the ability to block emails sent from addresses included in these lists.

An example : if you send an email to Mario Rossi from your domain info@acaso.it with IP address 122.122.122, Mario's mail servers will scan your data. If info@acaso.it or your IP address are present in these lists, your email will end up in spam or rejected completely.


What are the main blacklist providers?

There are several blacklist providers, however the most popular are:

  • Spamhaus : an international organization that helps most Internet Service Providers track and block spam and malware.

  • Spamcop - Spam reporting service that allows recipients of commercial emails to report IP addresses

  • Barracuda: Enables businesses to manage email security with protection from threats, spam, viruses and spooling.

Major email service providers use these lists, so it is a good idea to check that your domain is not listed on any of them.

How to avoid being blacklisted?

It is important, even if you do not send spam content, to keep in mind some factors:

  1. Spammers are the most active senders (it is estimated that 85% of all emails sent are spam), so to avoid being one of them it is better not to suddenly start sending large volumes of emails

  2. Do not use purchased or rented email lists.

  3. Clean up your contact list: Sending emails to invalid addresses leads to a high bounce rate, which is a major warning sign.

  4. Unsubscribe link : the lack of this possibility, that is, the possibility to unsubscribe from the newsletter, in addition to not complying with the laws for the GDPR, could increase the rate of "spam" complaints from users. People may not remember having subscribed, this link allows them to easily unsubscribe instead of pushing them to report.

  5. High sending frequency : Try not to send more than one email per week and make sure your content is unique and interesting, avoiding words like "free", "promotion", capital letters, the color red and numerous exclamation points in the subject line.


Conclusions

Following the newsletter sending guidelines will keep you off email blacklists, make sure your domain is configured correctly, and consistently work to keep your bounce rate and spam complaint rate low.

If your domain ends up on a blacklist, find the cause and fix it!
