A client encounters email delivery issues

A client marks your emails as spam

Most often, suppression lists contain unsubscribed emails, recipients who have opted out of receiving your emails. These email addresses are usually added automatically. However, customers sometimes ask to be manually removed from your mailing list.

Bounced emails

Hard bounce

When it comes to “hard bounce”, the origin is less clear. This means that the reasons are much more diverse. These may include the non-existence of the email address, a full inbox, an inactive domain or problems with the recipient’s server.

How to manage a suppression list?

Automating the management of an email suppression list is essential for improving the deliverability of your emails. Email addresses are automatically added to this list, so they won’t receive future email campaigns. It’s this streamlined process that ensures the health of your emails without manual intervention. Not bad, eh?

Another option is to manually add emails to the suppression list. This is particularly useful, for example, when one of your users asks you to do so, or when switching between two emailing solutions.

How does it work? Import a CSV file into the suppression list of your current mailing solution. The email addresses are transferred directly and seamlessly, preserving the deliverability of your emails. Smooth transition guaranteed!
