With email validation, you won’t waste your budget on email addresses that don’t exist. First 100 validations & 10,000 emails are free every month.
See How Mailgun Can Help
Maximize deliverability with comprehensive verification
Mailgun performs a three-step validation check for each address we verify, including a check against the mailbox provider to determine if the address is valid.
We also use our internal data from sending 10+ billion emails every month to give you the most accurate results possible. If we know an email address is deliverable because we recently delivered an email there, you get the benefit of that data.
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 based on real-world data + RFC spec to ensure more accurate validation.
Custom ESP grammar
All major ESPs have their own set up custom grammar 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.
It’s easy to get started. And it’s free.
