Authentication, IP whitelisting and more is easy with the SocketLabs email platform.

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.

Harness more functionality

Want to split transactional mail from marketing? Easy, plus our in-depth reporting can show you how each stream is performing. Want to process unsubscribes and complaints? Sure. SMTP doesn’t have to be a slog.

Keep email flowing with 99.999% uptime and robust reporting to monitor performance.

We take email seriously. The SocketLabs experts (who are actual email veterans) won’t leave you hanging for hours or days. We’ll help, pronto. Faster fixes mean faster results.
