Send without jumping through hoops

While one sender might be relatively new to email and has the time and capacity to set up their instance with proper authentication, some simply don’t.

To assist those senders, we’re able to offer IP allow-listing to create an environment in which you can hand over an IP to us, even without authentication, and have it put on our allow-list so you can send mail directly through your account without a care.
