Best email verifier for newsletters: price to clean 50,000 subscribers once

Which one should you pick?

• Pick Listclean if you clean a list of up to about 100,000 once or a few times a year and want credits that never expire.

• Pick Emails Checker if you clean a list once or a few times a year and want credits that never expire.

• Pick BillionVerify if you verify under about 50,000 addresses a month, clean a list once, or want to resell verification under your own brand.

• Pick SimpleVerifier if you verify or re-check lists every month and want one flat monthly price instead of credits, with catch-all addresses kept risky rather than marked valid.

  Skip SimpleVerifier if you want the lowest price for one small list, where another vendor's pack can cost less (cost by list size); you need your data processed only inside the EU (our service providers process data in several countries, including the US); or your list is mostly Outlook.com, Hotmail or Live addresses, which Microsoft currently won't let us confirm, so they come back risky (why).

• Pick VeriMails if you verify up to about 50,000 addresses a month: its plans are $15 for 10,000 and $39 for 50,000, and prepaid credits never expire.

• Pick Proofy if you clean a list of up to about 25,000 once or a few times a year and want credits that never expire.

• Pick Bulk Email Checker if you clean a list of up to about 25,000 once or a few times a year and want credits that never expire.

• Pick MyEmailVerifier if you verify under about 25,000 addresses a month, want credits that never expire, or want to pay with PayPal or crypto.

• Pick Truelist if you clean a list once or twice, or your B2B lists are mostly catch-all domains and you want those resolved rather than graded.

• Pick Reoon if you clean one list once, or a few hundred addresses a day, and want the lowest per-address price with credits that never expire.

How we compared

We priced one clean of 50,000 addresses on the email verifiers we hold dated prices for, from our dated vendor data, and list each vendor's pricing page under its row. The table shows SimpleVerifier and the 9 lowest-priced of the vendors priced at this size; vendors with no published price at this size are left out. We did not run an accuracy benchmark, so nothing here ranks accuracy: test a shortlist on a sample of your own list, including addresses you know are dead.

10. 10. Reoon

    Best for: Buyers who want a one-off clean at a low per-address price. Its smallest instant pack is 10,000 credits for $11.90, which undercuts a month of SimpleVerifier for a single pass

    • A single pass is cheap: its smallest instant pack is 10,000 credits for $11.90, and instant credits never expire.
    • Unknown results are never charged; its FAQ says they are refunded automatically when the task finishes.
    • Watch out: The subscription is a daily allowance that does not carry over, so a large list either waits for days of credits or is bought again as an instant pack.

Common questions

When should a newsletter clean its list?

Before a large send, before moving to a new platform and after a long gap without sending. See how often to clean your list.

Should I delete invalid subscribers or keep them?

Remove invalid addresses; they cannot receive mail and only add bounces. The delete or keep guide covers risky ones.

Which route is cheapest for me?

It depends on volume and how often you repeat it. At one clean of 50,000 addresses the lowest published routes are Listclean ($35), Emails Checker ($35) and BillionVerify ($36); see cost by list size to price another volume. SimpleVerifier Pro is $39 a month with the first 100,000 checks a month at full speed, then slower, never cut off.

Is the cheapest verifier the most accurate?

We did not run an accuracy benchmark, so nothing here ranks accuracy: test a shortlist on a sample of your own list, including addresses you know are dead.
