Email delivery that you can count on

Nobody likes to wait for a password reset email that takes too long to deliver. Even worse, if it ends up in the spam folder, you can't find it, and when you do, it's already expired.

Sidemail solves this problem. No more upset customers that didn't receive their email on time, every time.

Simple to integrate

Start sending emails from your application in just a few minutes thanks to Sidemail API—modern JSON API that is rich in features, well documented, and designed with developer experience in mind. Visit the docs.

	toAddress: "user@email.com",

	templateProps: { url: "https://your.app/sso?token=123" },
});
