If you’re sending strictly opt-in email, you might be eligible to use one of GMass’s own SMTP servers, rather than setting up an SMTP service on your own.
We are selective about who we let use our own SMTP servers or our SendGrid account, so please don’t take offense if we deny your request. Additionally, it can take a couple days for us to review your request, since we manually review every user’s sending history to determine if you are eligible.
Note: We require you to include an unsubscribe link and a physical address on all messages sent through GMass’s SMTP server.
To apply to use our SMTP service, please fill out this form.
We’ll be notified of your request and will email you as soon as we complete our review.
If approved, your account will be linked to one of our SMTP services.
We won’t provide you with the username/password, but behind the scenes, your account will be linked to the server. And you’ll now see the choice to send either via the SMTP service or via Gmail in the GMass Settings box for your account.
There is no extra fee if you qualify, but do note that sending over SMTP is subject to usage-based billing, outlined here.
