Self-authenticate your emails using your own domain - Change key size to 2048 bits


Can we change the key size to 2048 bits, an outside audit flagged the 1024 key that was generated. 


Hello @robertw7630 ,


At this time, 1024 is the only key available for self-authentication with us. I've marked your account as interested in having 2048 available, and submitted it to our deliverability devs. If and when there's an update to the existing feature request, they'll notify you directly. At this time there is no ETA on the addition of the more complex keys. 


If you have additional questions, please reach out to our Deliverability team.

I would also like to know if 2048 bit becomes available.

Kind regards,
