Fast verification for most lists,
deep checks for the hard ones.
Choose a mode for each list. Quick clears most lists in minutes, and Deep keeps retrying hard-to-verify contacts.
Quick Verification
5 to 30 minutesBuilt for speed with great accuracy. Addresses that are difficult to verify are skipped, so your list is ready fast and your campaign isn't held up.
Deep Verification
20 minutes to 5 hoursBuilt for harder lists. It runs additional checks and retries temporary server issues, giving difficult contacts more chances to be verified.

Why built-in email verification beats a separate tool
A standalone verifier means another subscription, per-email credits and a CSV round trip before every campaign. In Deliveryman, verification runs the moment you upload a list.

Frequently Asked Questions
Is email verification really unlimited?
Yes. Verification is included in every plan, so you can verify every contact you upload. There are no credits to buy and no per-email fees.
How long does verification take?
Quick Verification finishes in 5 to 30 minutes. Deep Verification takes 20 minutes to 5 hours, because it runs extra checks and retries temporary server issues.
Should I use Quick or Deep Verification?
Quick is the right choice for most lists. It's fast and skips addresses that are hard to verify. Choose Deep when a list has lots of hard-to-verify contacts and you want each one to get more chances.
What happens to invalid or unsafe contacts?
Every contact keeps its status, so only valid addresses are used in your campaigns. You can export any status as a CSV if you want to review or clean a list yourself.
Can I skip verification?
Yes. You can skip verification for a list, or skip a job that's stuck. We still detect each contact's email provider, so ESP data is never lost.
Do I still need a separate verification tool?
No. Deliveryman checks for invalid, temporary, unsafe, catch-all, inbox-full and webmail addresses before you send, and campaign protection keeps bounce rates low after launch too.
