What to look for

Price at your volume
Compare the cheapest way to buy the number of checks you actually run, not the headline per-email rate.
Whether credits expire
Credits that expire turn a cheap bulk pack into a loss if your sending is seasonal.
What you pay for unclear answers
Unknown and catch-all results can be a large share of B2B lists. Check whether they cost a credit.
Catch-all handling
Some tools stop at accept-all. Others resolve part of them, or offer a deeper check you pay for only when it works.
Evidence on each result
A verdict you can't inspect is hard to trust. Look for the mail server, the mailbox answer and the catch-all test.
