MailerCheck Pricing Explained (2026): Credits, Plans and Cost per 1,000
MailerCheck costs $80 as a pack for 10,000 checks and $500 as a pack for 100,000; for 1,000,000 it is $2,000 as a pack. MailerCheck is the cheaper choice only at very small volume. 1,000 credits are $10 and 2,500 are $25, under a month of Pro. At 5,000 ($45) Pro is already cheaper, and the gap widens with every pack. MailerCheck makes sense mainly if you want a verifier partnered with MailerLite or inbox placement tests from the same balance. This post lists every price we have on file, the cost per 1,000, what happens to unused credits, and how a flat $39 Pro plan compares at each volume.
Figures come from the MailerCheck pricing page as we last read it on 3 November 2026. We did not re-read the page today, so check it before you buy.

Prices verified 3 November 2026. Per-1,000 figures are price divided by credits, our arithmetic.
Also on the page: The credit table also lists 2,000,000 credits at $2,000 and 5,000,000 at $5,000.
Pack or subscription?
MailerCheck is pay-as-you-go credits only on the page we read, with no monthly subscription, and credits never expire. That makes it easy to buy once and use over months, but it also means every pass over a list is paid again.
Credit expiry, free credits and refunds
- Credit expiry: Its pricing page says credits never expire (read 3 November 2026).
- Free credits: 10 free credits at sign-up, for list verification only (as read on 3 November 2026).
- Refunds: Not checked today.
- Duplicates, unknown and catch-all results: Inbox placement tests and email insights are sold from the same credit balance, at 200 credits each. Duplicate and catch-all billing: not checked today.
How a flat $39 Pro plan compares
Pro is $39 a month: the first 100,000 checks a month at full speed, then slower, never cut off. Pro is not priced per credit, so re-checking an overlapping list costs no extra, and confirmed results are cached for 14 days.
| Volume | MailerCheck | SimpleVerifier Pro | Cheaper on price |
|---|---|---|---|
| 1,000 a month | $10 pack | $39 | MailerCheck |
| 5,000 a month | $45 pack | $39 | SimpleVerifier |
| 10,000 a month | $80 pack | $39 | SimpleVerifier |
| 100,000 a month | $500 pack | $39 | SimpleVerifier |
| 1,000,000 a month | $2,000 pack | $39 (first 100,000 at full speed, then slower) | SimpleVerifier on price; Pro is slower past 100,000 |
Past 100,000 a month Pro runs big lists slower rather than charging more or cutting you off, so a million-address list takes longer than on a per-credit vendor that sells you the speed. If time matters more than money at that size, say so before you pick.
When MailerCheck is the cheaper choice
MailerCheck is the cheaper choice only at very small volume. 1,000 credits are $10 and 2,500 are $25, under a month of Pro. At 5,000 ($45) Pro is already cheaper, and the gap widens with every pack. MailerCheck makes sense mainly if you want a verifier partnered with MailerLite or inbox placement tests from the same balance.
Keep MailerCheck if you already send through MailerLite or MailerSend and want a verifier partnered with MailerLite, with credits that never expire.
When a flat plan is the better choice
- You verify more than the volumes above every month, or you re-check the same lists. On MailerCheck, it is priced per credit, so cleaning the same list twice costs twice.
- You want an email finder, an API and a remote MCP server in the same plan as verification.
- You send from Instantly or Smartlead and want leads tagged in place.
Questions to ask before you buy
- What does one check cost in credits? Some vendors charge more than one credit for deeper checks.
- Do credits expire, and do plan credits roll over? Packs and subscriptions often differ.
- Are duplicates, unknown and catch-all results charged? See what email verifiers charge for.
- What does a re-check cost? Every pass is a fresh purchase on per-credit pricing.
- What is refundable? Not checked today.
