Validation FAQ

Why do I need to validate emails?

High bounce rates damage your sender reputation with email providers and can get your account blacklisted. Validating before sending keeps your list clean and your deliverability high.

How does SMTP verification work?

We connect to the recipient mail server and simulate the beginning of a delivery to check if the mailbox exists — without actually sending an email.

Can I validate my CSV list before importing?

Yes. Upload your CSV and run validation before enrolling contacts in a campaign. Invalid emails are flagged so you can clean your list first.
