At a glance
| Decision area | RefreshList | MailerCheck |
|---|---|---|
| Pricing and credits | One-time USD credit packs; one credit per completed unique check; paid credits never expire. | Packaged plans; verify current monthly or one-time quote. |
| Duplicate and unknown billing | Duplicates are assessed before verification and are free; unknown results are charged because they are completed checks. | Confirm rollover and inconclusive-result treatment in plan terms. |
| Input and throughput | 100 MB and up to 1,000,000 emails per file; multiple lists can run from one account. | Confirm current file and list limits. |
| Result model | Six signal groups with fifteen detailed statuses, plain-language definitions, and an explicit unknown state. | Compare the competitor status taxonomy and whether uncertainty is separated from invalid. |
| Exports and audit trail | Source columns stay attached to categorized result downloads; each list keeps independent progress, credits, and downloads. | Check whether original row context and separate job history are preserved. |
Why RefreshList is different
RefreshList is a focused verification workspace without marketing-suite complexity.
- See the billable set first: local preflight identifies duplicates, malformed rows, and eligible checks before a paid run.
- Keep uncertainty visible: unknown is a distinct outcome, never silently presented as valid or invalid.
- Work in parallel: upload multiple lists and track each job independently in the same account.
- Leave with evidence: categorized downloads retain the original source columns for reconciliation.
Who should choose the other tool?
MailerCheck may be the better fit if you need its broader integrations or the pricing and status model described above. RefreshList is the better fit when the priority is a focused, transparent list-cleaning workflow.
Buyer checklist
Are these rankings?
No. They are decision guides, not a claim that one vendor wins for every team. Run the same representative list through both tools and compare the exported rows, result categories, time, and final bill.
What should I verify before purchase?
Check the linked vendor source for current pricing, expiry, file limits, retention, API limits, and treatment of duplicates or unknown results.
