How much does it cost to verify 10,000 emails?

Most email verification services charge per address, so the headline price is easy to compare. The real cost isn't. Two services with the same price per 1,000 can leave you paying very different amounts for the same list.

Here's what to look at before you buy.

The quick answer

With ListBouncer, verifying 10,000 addresses costs $35, one time. That's $3.50 per 1,000.

Addresses	Price	Per 1,000
2,000	$9	$4.50
5,000	$19	$3.80
10,000	$35	$3.50
25,000	$69	$2.76
50,000	$119	$2.38

There's no subscription, and the credits never expire. Every account also gets 100 free credits, so you can try it on part of your list first.

What changes the real cost

1. Subscription or pay as you go

Some services sell monthly plans. That works if you clean lists every week. Most small businesses and newsletter senders don't: they clean before a big send, after a long break, or once a quarter. On a monthly plan you pay for the months you don't use.

With one-time credit packs, you pay when you clean and nothing in between.

2. Do credits expire?

Check this one carefully. If credits expire after a month or a year, a pack you bought for one big clean can quietly lose value. If they never expire, the leftover credits are still there for your next clean.

3. Are duplicates charged?

Exports from spreadsheets, CRMs and old forms often list the same person twice, sometimes with different capital letters or a stray space. If a service charges for every row, you pay twice for the same address.

ListBouncer checks each unique address once. Duplicates and broken rows (blank cells, values that aren't email addresses) are free.

4. Are "unknown" results charged?

Some mail servers won't say whether a mailbox exists. The result comes back unknown, which means the service couldn't give you an answer.

Check whether you pay for those. With ListBouncer you don't. Anything that comes back Unknown gets its credit back when the clean finishes, and the report tells you why each one couldn't be confirmed.

5. What you get back

A cheap check isn't cheap if you can't use the result. Look for:

• A clean file you can import straight away. ListBouncer formats it for MailPoet, Mailchimp or Klaviyo, or as a standard CSV.
• A reason for every address, so you can see why something was flagged before you delete it.
• Separate handling for providers that can't be confirmed. Yahoo, Outlook, Hotmail and AOL don't let anyone confirm a mailbox. ListBouncer keeps them in their own list instead of guessing.

A worked example

Say you export 10,600 rows from your email platform. 400 are duplicates and 200 are blank or broken.

• Addresses charged: 10,000 (duplicates and broken rows are free)
• Cost: one 10,000-credit pack, $35
• If 800 come back Unknown: 800 credits go back to your account for next time

So you'd pay for 9,200 answers, and the other 800 credits stay in your balance for next time.

Is it worth paying to clean 10,000 addresses?

Usually, yes. The cost of not cleaning shows up in two places:

• Your email platform bill. Most platforms charge by the number of contacts. Removing dead addresses can drop you into a cheaper plan.
• Your sender reputation. If too many of your emails bounce, inbox providers start sending your mail to spam, and some email platforms pause your account. That costs far more than $35 to fix.

Not sure your list needs it?

Check a few addresses you're unsure about with our free email checker. It does 10 a day without an account. If several come back bad, the rest of the list is worth a full clean.
