Email Deliverability

Missing or Delayed Emails Lead to Customer Churn

Customers churn when emails 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 engaging and retaining your customers.

Email Deliverability is Challenging and Time Consuming

Diagnosing email security issues, 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.
