Using the email headers customisation tool

We all know how important email headers are and how they affect email deliverability. However, until now, you couldn’t customise which email headers to use when sending out your email campaign. Thanks to our newest feature, you can customise email headers by selecting the ones you need and deselecting the ones you don’t.

You can tell a lot about an email by looking at the header information - everything from who has sent it, who has routed it, uses which IP address for sending it, and if SPF and DKIM validations. Typically, they also contain information on other variables for internal usage, like the List ID of the mailing list you are sending or the abuse URL in case the user wants to complain about unsolicited emails.

However, some customers find that they get better email delivery rates by excluding specific headers, so we decided to give this feature to all our customers so they can customise to what works best for them. Don’t worry. We have not listed any headers that are a MUST to ensure recognition of bounces and complaints.
