# How our email verification works

**TLDR:**

* You don't need to verify Pronto emails
* Every email is triple-verified
* Catch-all emails are also verified. We uncover likely valid emails out of catch-all emails.

# How email verification works

Every email is validated. We use a combination of two verifiers and a custom provider score to classify the email into three categories:

### Valid emails

These emails bounce around 1% of the time.

### Invalid emails

If the email is invalid, we continue enrichment until we find a valid email. Invalid emails found do not consume credits.

### Catch-all emails

Traditional methods cannot confidently determine if these emails are valid or not. In this case, we use a **3rd validation method** to gain more insight into the deliverability of this email:

* If the email shows activity signals, we mark it as "likely valid." On average, the bounce rate for these emails is 10%.
* If we have no signals with this email, it remains in the catch-all category. On average, the bounce rate for these emails is 26%.
