Deliver email, come rain or shine

Notifications and other app-generated emails are critical to SaaS success. But operating email infrastructure is a difficult, time-consuming distraction from building great products. SparkPost makes it simple for teams to implement notifications and other product emails with reliability and security your business can count on.

Don’t take risks on the wrong email infrastructure

Email is difficult to scale, and building and maintaining it requires specialized operational skills. That’s one reason 28% of all email is undelivered or lost in the spam folder. Even worse, unsecured email is today’s primary vector for phishing attacks. That’s a risk your business can’t afford.

The Most Trusted Email Delivery Service

The world’s most demanding senders rely on SparkPost to deliver billions of emails every day. That’s more than 25% of the world’s non-spam email.
