Features
No code needed. Just connect your existing provider account and go.
Use the email checker you already have
Connect NeverBounce, ZeroBounce, or MillionVerifier — whichever you already pay for. Switch anytime without starting over.
Three checks, not just one
Every email gets checked three ways: format, domain, and mail server. Problems get caught before you hit send.
Skip the shared inboxes automatically
Addresses like info@, sales@, and support@ are shared inboxes — not real people. The template spots and flags them for you.
Clear verdicts, no guesswork
Every email gets a clear label — Valid, Invalid, Risky, or Catch-All. You decide what to do, with the full picture in front of you.
Verify thousands at once
Run your entire list in one go. No babysitting required — thousands of emails verified while you do something else.
Keep your domain off the blacklist
Removing bad addresses before you send is the fastest way to stay out of spam folders and keep your domain healthy.

Get in TouchFrequently Asked Questions
Everything you need to know about this template
Which verification service should I use?
All three — NeverBounce, ZeroBounce, and MillionVerifier — are accurate and reliable. NeverBounce is fast, ZeroBounce adds extra data about the email owner, and MillionVerifier tends to be the most affordable. If you already have an account with one, start there. The template works the same with all three.
Do I need to pay for API credits separately?
Yes. The template gives you the workflow — you supply the API account with NeverBounce, ZeroBounce, or MillionVerifier. All three offer free trial credits so you can test before paying. Typical cost is $0.005–$0.01 per email, which is much cheaper than sending to bad addresses.
What are role-based emails and why should I filter them?
Addresses like info@, sales@, and support@ go to shared inboxes — sometimes managed by a team, sometimes by a bot. They almost never open emails, rarely respond, and some email platforms will penalize you for targeting them. Filtering them out improves your open rates and protects your sender score.
How accurate is the verification?
Very accurate, but not perfect. Format checks are nearly flawless. Domain and mail server checks are reliable. The tricky ones are catch-all domains — they accept every email, but some never actually deliver them. The risk scores help you decide what to do with those borderline cases.
Can I verify emails without an external API?
You can check email format without an API, but that's just basic formatting. To know if an address is actually deliverable, you need API access to NeverBounce, ZeroBounce, or MillionVerifier. They do real server-level checks that Google Sheets can't do on its own.
Are there any limits on batch size?
The template handles thousands of emails in a single run. Practically speaking, it's smooth up to about 10,000 rows. For larger lists, break them into batches to avoid timeouts. There's progress tracking built in so you can keep an eye on things.
