Best email verifier for AWeber: 7 options compared

Which email verifier should I use for AWeber?

What it is

Email verification with a real SMTP mailbox check: each address comes back valid, risky or invalid with a reason. Includes an email finder on Pro and up.

Price per check

Starter $9/mo for 2,500 ($3.60 per 1,000); Pro $39/mo, 100,000 a month at full speed ($0.39 per 1,000 when used), then slower, never cut off. Business $99/mo with 300,000 at full speed; Agency $249/mo with 750,000 at full speed.

One-time packs

10,000 for $15 ($1.50 per 1,000); 25,000 for $29 ($1.16 per 1,000); 50,000 for $49 ($0.98 per 1,000); 100,000 for $79 ($0.79 per 1,000); 250,000 for $169 ($0.68 per 1,000). Credits never expire, run at standard speed, CSV verification only (no API or finder).

Free checks

First 100 email checks free with a Google sign-in, no card, once per account. Single checks on the free email checker need no account.

Billing

Monthly subscription, cancel anytime (yearly billing optional). One-time packs are listed above. Starter allowances reset monthly and do not roll over.

Speed today

One sending IP today, shared by every customer: about 13,000 mailbox checks a day in the standard lane. Bad syntax, dead domains and disposable addresses return at once; a list of 100,000 takes days, not hours, and each job shows its estimated finish time.

Catch-all handling

Catch-all (accept-all) addresses stay risky, never valid, and are graded higher, medium or lower likelihood with the reasons. Anything a mail server does not confirm is risky.

API and MCP

REST API on Pro, Business and Agency (Pro includes 10,000 calls a month, then $1.50 per 1,000). Remote MCP server with 6 tools for Claude, ChatGPT, Cursor and VS Code. No API on Starter.

Integrations

Connects to Instantly, Smartlead, HubSpot and Mailchimp by API key: verifies a campaign or list and tags each contact with its result. CSV in and out for any other tool.

Phone

Free phone format checks (country, type range). Live carrier and line-type lookups come with Pro + Phone at $49.99/mo (5,000 a month). It never says a number is in service.

What it does not do

No sending, warmup or inbox placement tests. No published accuracy benchmark against other verifiers. Catch-all domains, Yahoo and AOL cannot be confirmed, and Outlook.com and Hotmail mailboxes are not probed while Microsoft refuses checks from our server's network: all of these come back risky, never valid.

SimpleVerifier facts from our pricing page and product. Last updated October 31, 2026.

Which one should you pick?

• Pick DeBounce if you want a low price on a one-off clean of a small or medium list, with pay-as-you-go credits that never expire.

• Pick EmailListVerify if you verify a steady 5,000 to 10,000 addresses a month ($16 a month for 5,000), or want pay-as-you-go credits that never expire.

• 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 MillionVerifier if you clean a very large list once in a while: 1,000,000 credits are $449 one-time, never expire, and there is no subscription to cancel.

• Pick NeverBounce if you want verification synced inside many marketing tools: its pricing page lists 80+ integrations.

• Pick Emailable if you want 250 free credits to test with and credits that never expire.

• Pick Clearout if you pay yearly and also want an email finder and prospecting on the same credit balance.

How we compared

On 3 November 2026 we read AWeber's own help pages for any built-in email verification and list them under its row. We did not re-check the other verifiers' sites for a AWeber integration this time, so their column says "not checked"; any of them can take a CSV export, and their prices are the ones read on 27 October 2026. To keep the table short it shows the lowest-priced ones and leaves out Bouncer, Kickbox, ZeroBounce and Hunter, which are in the main roundup. 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.

Common questions

Does AWeber verify emails itself?

No. On 3 November 2026 AWeber's help article said AWeber cannot be used to clean your mailing list and will not find or remove undeliverable addresses for you. It screens imports, and an import with many addresses that would cause high bounces and complaints is not accepted.

How do I verify AWeber contacts with SimpleVerifier?

There is no AWeber connector, so it is a CSV round trip. Export: In AWeber, go to the Subscribers page for the list. Use the filter menu to narrow the subscribers if you need to, then search. Click Export CSV to download the subscribers shown. Upload that file to SimpleVerifier as it is; the email column is found automatically. You get three files, valid, risky and invalid, each with every original column, so import the valid file back into AWeber. The export steps follow AWeber's help article; the full AWeber export guide has the details.

Can I verify new contacts automatically instead of exporting?

Yes, with the SimpleVerifier API, which comes with Pro and higher plans. Call it from Zapier, Make or n8n when a contact is created, and branch on the status field: valid, risky or invalid. There is no packaged SimpleVerifier app in those directories yet; the guides use their HTTP or webhook steps.

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.
