Engage vs Hunter — a polished finder, or a definitive answer on Microsoft 365?

Hunter is a polished, respected email finder with a great UI and a strong track record on Google domains. For a lot of teams it is a solid default, and we are not going to pretend otherwise.

Engage does the same job — find + verify — and adds the thing that decides deliverability on the hardest domains: a definitive answer on Microsoft 365, instead of a guess.

Where finders get Microsoft 365 wrong

SMTP verification is honest on Google but not on Microsoft 365 — O365 returns a 5.4.1 error that is identical whether the mailbox exists or not, from any IP (anti-enumeration). So the result comes back as "unknown" or an unresolved catch-all, and you find out it bounced only after you send. On O365-heavy lists that is exactly where a polished finder still guesses.

What you get with Engage

Engage doesn’t guess on Microsoft 365 — the inboxes most tools bounce on. You get a clear yes or no. And for every email, you see why it passed or failed — not just a score you have to trust.

What we consider table-stakes (and match)

Pay-per-verified, non-expiring credits, and provider detection surfaced not hidden — we match those. On top: fair refunds (bounces are free, refunds no-questions).

So this is not "Engage wins everywhere" — it is "find + verify in one, with a definitive O365 answer, per-row transparency, and refunds you can trust."

Which should you pick?

• You want a polished workflow on mostly Google domains → Hunter is a strong choice.
• Your lists are Microsoft 365-heavy, or you want per-row provider/catch-all transparency and fair refunds → Engage gives a definitive O365 answer instead of a guess.

Both find and verify B2B emails well. The difference shows up on O365-heavy lists and when something bounces — where a definitive answer and a fair refund actually matter.
