GMass gives you the ability to send unlimited emails by connecting a third-party SMTP service to your account. This allows you to effectively break Gmail’s sending limits.
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.
Important: This is different than our cold email sending server. You can find all the info you need for that server on our page about ColdSMTP.
We are selective about who we let use our own SMTP servers, 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.
Only GMass packs every email app into one tool — and brings it all into Gmail for you. Better emails. Tons of power. Easy to use.

This is a great idea but how can we authorize sending through SendGrid if we are using DMARC? Can we have SendGrid sign with a DKIM signature that we can authorize if the SendGrid account is managed by GMass?
If we put the IP addresses assigned to this account in our SPF, how will SendGrid use our domain on the Return-Path in the header of our email so it will be properly aligned with the From: domain for DMARC?

Hi Joel,
Unfortunately, we aren’t able to outright respond to this request as you would have to submit your request via the instructions in this article. Your request will be forwarded to the designated team members who handle approvals for using our SMTP.
Is sendgrid will automatically be cancelled when we cancel gmass account?
This is a much-needed initiative, it will ease our lives at great extents.
I’ve submitted the sendgrid request 2 weeks ago and haven’t heard back yet
