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.
Every email is validated. We use a combination of two verifiers and a custom provider score to classify the email into three categories:
These emails bounce around 1% of the time.
If the email is invalid, we continue enrichment until we find a valid email. Invalid emails found do not consume credits.
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%.
