Do you provide personalized DKIM & SPF to eliminate the 'on behalf of' message?

Yes Mailjet supports personalized SPF & DKIM records! To customize these records, follow our simple step-by-step guide at SPF & DKIM Authentication

But I am using Gmail (Yahoo, Hotmail, …). How do I change those SPF & DKIM records?

Bummer. You cannot change the SPF & DKIM records for Gmail, Hotmail, Yahoo or any other free webmail accounts.

Yahoo! for example, has decided to tighten up on their DMARC (Domain-based Message Authentication, Reporting and Conformance) Policy. In a nutshell, DMARC is a standardization policy used by some receiving domains to authenticate emails using SPF & DKIM. Yahoo has set their policy to tell all receiving domains to reject any emails that has a Yahoo email address in the From: field but comes from a non Yahoo server (i.e. it was sent via an ESP such as Mailjet).

This is why you should definitely consider adding a sender address that is linked to your domain name. If you are using a custom domain email, you can then setup SPF and DKIM to help with your deliverability. This will give your emails a better chance of being delivered to the recipient’s inbox… which is what you want, right?
