Email Deliverability

Missing or delayed product emails lead to customer churn

Customers churn when emails sent from your app are lost in spam folders or delayed. Whether you’re building a high-growth consumer service or enterprise software, and sending billions—or even hundreds—of messages a month, email plays a critical role in acquiring and retaining customers.

Email deliverability is challenging and time consuming

Ensuring emails are delivered to user inboxes can often feel more like art than science. Diagnosing email issues security, ongoing monitoring of spam blacklists, and working with very large ISPs is incredibly time-consuming and requires a skillset many engineering teams don’t have.

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.
