Apply to use OUR own SMTP services and overcome Gmail's limits

SendHustle 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 SendHustle’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.

Note: We require you to include an unsubscribe link and a physical address on all messages sent through SendHustle’s SMTP server.

To apply to use our SMTP service, please fill out this form.

Thanks to our instant approval system, you’ll find out right away if you can continue sending your campaign through our server. (If you’re denied, our team will manually review your case.)

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 SendHustle 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.
