Guide
Pay-as-you-go email verification explained.
Subscriptions make sense for constant volume. For everyone else, credits are simpler and usually cheaper.
No monthly subscription · Credits never expire · Unknown results use no credits
Subscription vs pay as you go
A subscription charges you every month whether you verify or not. Pay as you go charges only when you buy credits. If you verify a few times a year, credits almost always cost less.
How MailGuard credits work
- 1 credit = 1 Passed or Failed result
- Unknown results use 0 credits
- Duplicates are removed before checking
- Credits never expire
- Checkout through PayPal
Estimating how many credits you need
Start with the number of unique addresses in your list. You'll usually use slightly fewer credits than that, because Unknown results are free.
What MailGuard can help with
- Checking single addresses or bulk CSV/TXT lists before a campaign
- Sorting each address into Passed, Failed, or Unknown, with a plain-language reason
- Flagging disposable domains, role accounts, syntax issues, and catch-all behavior
- Exporting a filtered list that contains only the results you choose
- Paying only for Passed and Failed results, since Unknown results use no credits
Limitations
Verification reduces uncertainty before sending. It does not guarantee inbox placement and does not replace consent or list hygiene.
