MillionVerifier's free allowance is 100 credits, and you don't need a card to claim it (millionverifier.com, read 24 September 2026). One credit checks one address, so the free credits cover a short test list. For anything bigger, you buy credits.
Paid credits are pay-as-you-go only. The figures on its site were 50,000 checks for $89 and 1,000,000 for $449, and MillionVerifier says twice that credits never expire. The page listed no 1,000 or 10,000 tier on the day we read it, so price a small first order at checkout. The MillionVerifier pricing breakdown has the full table.
Free credits matter less than the billing rules behind them. Ask two things of any verifier: are unknown results billed, and do credits expire? MillionVerifier doesn't bill unknowns and doesn't expire credits. The vendor-by-vendor list is on which verifiers charge for unknowns.
ZapBounce gives every account 100 free checks a month, every month, with no card. Paid checks start at $5 for 1,000, so you can buy a small batch with no minimum, and $89 buys 50,000. Credits never expire, and unknown results and duplicates are never billed. You can also pick a monthly plan at 15% less than the same credits pay-as-you-go.
Test both on the same sample. Take 100 addresses from your real list, run them through each free allowance, and count how many rows come back unknown or catch-all. That share tells you more than a headline accuracy claim. The ZapBounce vs MillionVerifier page sets the terms side by side.
