How to Verify a Purchased Email List Before You Send
Verifying a purchased email list removes the addresses that will bounce, but it does not make the list permission-based, and it cannot find spam traps. Do the rules check first, then verify before the first send: upload the file and run your first 100 checks free with a Google sign-in, no card.
Step 1: Check the rules before the list
Some email platforms ban purchased lists outright, and consent rules differ by where the recipients live. The free purchased email list checker asks three questions and shows each rule with its source. If the answer is that you cannot send, no amount of verification changes it.
Step 2: Look at the file
Open it. Check the columns, the number of rows, duplicates and obvious junk. The email list cleaner removes bad syntax, duplicates, typo domains and disposable addresses in your browser before you spend any checks.
Step 3: Verify a random sample first
Upload about 100 random rows on the verify page and read the split. Bought lists tend to hold older addresses, so expect to see more invalid and risky rows than on a list you built. If the sample is poor, that is information about the list, and about the seller.
Step 4: Verify the whole list
If you go ahead, upload the full file and follow how to verify an email list: send only valid rows, test risky rows in a small batch and suppress invalid ones.
What verification does not fix
- Consent. The recipients may never have agreed to hear from you.
- Spam traps and recycled addresses. A mailbox that exists may be a trap or may belong to a new person.
- Catch-all domains. Many business domains accept every address, so those rows come back risky; see catch-all emails: what to do.
- Provider limits. Outlook and Hotmail rows currently come back risky and Yahoo rows are hard to confirm.
If you already sent to one
Stop, remove the invalid rows, and read recovering after sending to a purchased list. For the bounce numbers to watch, see what to do after a high bounce rate.
Cost
After the first 100 free checks: packs start at $15 for 10,000 checks and never expire (a one-off list suits a pack), Starter is $9 a month for 2,500 emails, and Pro is $39 a month with the first 100,000 checks a month at full speed, then slower, never cut off. See pricing.
Check the list
Upload it on the verify page: 100 free checks, Google sign-in, no card.
Common questions
Can I verify a purchased email list?
Yes. Upload it and every address comes back valid, risky or invalid with a reason. Verification removes dead addresses; it does not give you permission to email anyone.
Is it legal to email a purchased list?
It depends on where the recipients are and which platform sends the email. The free purchased email list checker lays out the rules with sources; this is not legal advice.
Will verification protect my sender reputation on a bought list?
It removes addresses that would hard-bounce, which is a large part of the damage. It does not remove spam traps or people who never agreed to hear from you.
What if I already sent to a purchased list and bounced?
Stop sending, remove the invalid rows and read the recovery steps in the guide to recovering after sending to a purchased list.
Check your list before you send
Real mailbox checks over SMTP, and nothing is sent to the address. Sign in with Google and your first 100 email checks are free, no card. Plans for bigger lists are on the pricing page.
