More Accurate Email Validations

Validation Based on Billions of Sent Emails

RFC states the formal rules for email addresses. However, in the real world ESPs accept addresses that are not RFC-valid, and reject addresses that are.

When we built our validator, we did so based on real-world data + RFC spec to ensure more accurate validation.

Bulk Email Validations
Custom Grammar Checks

Custom Mailbox Provider Grammar

All major mailbox providers have their own custom grammar rules that impact whether an email address is valid in the real world.

We’ve integrated custom grammar checks for Gmail, Hotmail, and Yahoo into our email validator and are always adding more custom grammar checks as we discover these rules.

Protect Your List From Typos

“Did you mean yahoo.com?”

People make typos all the time. Yahoo.com can easily become yaho.com and when it does, you can miss out on connecting with that customer.

That’s why we built in a suggestion service into our email validation service. When we have a suggestion for a common typos, we’ll return it along with invalid status, so you can offer the suggestion to your user.

Avoid high-risk recipients
