- You want the email tested as well as the list: spam score, inbox placement across 7 providers, previews in 50+ clients and an AI assistant sit beside the verifier. Verifalia sells verification only.
- You want to check an address without an account: Unspam's verifier answers 10 addresses a day with no signup and no card. Verifalia's 25 free daily credits need an account, one per organisation.
- You want to know an unknown costs nothing: Unspam never charges for an unknown, a duplicate or a malformed address. Verifalia says duplicates are free and does not state how unknown results are billed.
- You work from an AI assistant: Unspam has an official MCP server with five verification tools. Verifalia is reachable from assistants only through third-party Zapier and Pipedream connectors.
A Verifalia alternative that adds spam testing and previews to verification
Verifalia is an EU-hosted email verifier with three quality levels, about 40 status codes and SDKs in six languages, sold as credit packs from $7.90 for 1,000 or daily-credit plans from $9.90/mo. Unspam verifies single addresses and whole lists, charges nothing for unknowns or duplicates, and puts spam testing, inbox placement and client previews in the same plan, from $5/mo with 10 free checks a day.

Which one fits you?
- You want to choose how hard each address is checked. Verifalia's Standard, High and Extreme levels spend 1, 2 or 4 credits for more passes and longer waits on slow servers; Unspam runs one level.
- You need a real-time check on a signup form. Verifalia's API can wait for a result, and it ships a royalty-free JavaScript widget and SDKs for .NET, Go, Java, JavaScript, PHP and Ruby; Unspam's API answers asynchronously.
- Your lists are very large. Verifalia accepts files up to 100 MB, about 72 million addresses per list, in TXT, TSV, CSV, XLS and XLSX; Unspam takes up to 100,000 rows or 20 MB per upload.
- You want the most detail per address. Verifalia returns about 40 status codes, such as honeypot, catch-all timeout and disposable, where Unspam returns a status, a reason and an action.
Why teams move from Verifalia to Unspam.
Test the email, not just the list
Verifalia tells you which addresses are safe to mail. It does not test the message itself. Unspam scores the email against the spam filters, shows where it lands at 7 providers and renders it in 50+ clients, on the same plan as the verifier, so one account covers the list and the campaign.
No account for a quick check
Verifalia's free daily credits need an account, one per organisation. Unspam's verifier checks up to 10 addresses a day with no signup and no card, which covers the everyday case of checking a lead or a reply-to address before you write to it.
Billing you can predict
Unspam charges one credit per unique address with a definitive answer and nothing for unknowns, duplicates or malformed addresses, on one quality level. With Verifalia the cost of a list depends on the quality level you choose, at 1, 2 or 4 credits an address.

Unspam vs Verifalia, answered.
Is Unspam a full replacement for Verifalia?
For most list cleaning, yes: Unspam verifies lists of up to 100,000 rows and single addresses, also through its API and MCP server. Verifalia is ahead on very large files, a real-time signup check with a widget, SDKs and adjustable quality levels. Unspam adds spam testing, client previews and DMARC monitoring.
How does Unspam's pricing compare to Verifalia?
Verifalia sells credit packs from $7.90 for 1,000 down to $4,890 for 10,000,000, or daily-credit plans from $9.90/mo for 250 a day; a High or Extreme check costs 2 or 4 credits. Unspam charges one credit per unique address with a definitive answer on its Custom plan, from $6.40 per 1,000 down to $1.20 per 1,000 above 100,000, with a $5 monthly minimum.
How do the two handle catch-all addresses?
Neither guesses. Verifalia reports a catch-all server as possibly risky, and Unspam reports the address as catch-all with the action "review". A catch-all domain accepts every address during a check, so a probe alone cannot prove a mailbox exists.
Where is my data processed?
Verifalia stores data within the European Economic Area, in Germany, and lets you keep results from 5 minutes to 30 days. Unspam keeps a verified list for 30 days and then deletes it, along with its results.
