How to Verify 100 Emails for Free (No Card, Real Mailbox Check)

You can verify 100 emails for free on SimpleVerifier. Sign in with Google at the verify page, paste addresses or drop a CSV, and each address comes back valid, risky or invalid with a reason. No card is asked for, and the check is the same mailbox check the paid plans run. The 100 is a lifetime total per account, so spend it on a real slice of your list.

If you only need a handful of addresses, you do not need an account at all. The free email checker takes single addresses, five a minute.

What the 100 free checks give you

• 100 checks, once per Google account. It is not a monthly refill. When they are used, they are used.
• No card. Signing in with Google is the only step. Nothing is billed unless you choose a plan.
• The real mailbox check. The server looks up the domain's mail servers, connects, asks whether it would accept mail for that address, and disconnects before any message is sent. Free checks are not a cut-down syntax test.
• Valid, risky or invalid for every row, with a reason, and a CSV you can download.
• Honest labels. An address the server will not confirm is not marked valid. Catch-all domains, Yahoo, AOL and Microsoft consumer mailboxes come back as risky, because the server accepts everything or refuses to answer.

What it does not give you: a monthly allowance, API access, or a way to verify a list of thousands. That is what the paid plans are for, and we cover when they make sense below.

Step by step: verify 100 emails free

1. Pick the 100. If your list is longer than 100 rows, do not take the first 100. Take a spread: some from each source, some old, some new. The first rows of a file are often the oldest or the cleanest, which flatters the result.
2. Remove the obvious junk first. Duplicates, rows without an @, and blank cells cost you checks you could have kept. The free cleanup steps take a few minutes and need no account.
3. Sign in. Go to simpleverifier.com/verify and continue with Google.
4. Paste or upload. Paste addresses one per line, or upload a CSV with an email column. Open /verify if you are already signed in.
5. Run it. A hundred addresses finish in a short time because each one is a live conversation with a mail server. Results appear as valid, risky and invalid.
6. Read the risky rows. Do not treat risky as bad. It means the server did not give a definite answer. Look at the domains: a pile of risky rows on one company domain usually means a catch-all.
7. Download the CSV and compare it with what you expected. Do any invalid rows belong to people you know are active? Are any known-dead addresses marked valid? That is how you judge a verifier. The test plan for free checks lists addresses worth seeding.

Checking one or two addresses with no account

For a quick answer on a single address, use the free email checker. It needs no sign-in and allows five checks a minute. It is the right tool when you are sizing up a single lead or testing an address on a form. For anything that resembles a list, sign in and use the 100.

There is also a page that lists everything you can check without an account, including checks that look at a whole file's syntax, duplicates and dead domains without confirming mailboxes.

How the free 100 compares with other free tiers

Vendors define "free" differently, and the unit matters more than the number. Some give a one-time batch, some refill daily, some are credits where one verification may cost less or more than one credit. These figures come from each vendor's own public pages as recorded in our comparison data. Confirm before you rely on them, because free tiers change.

Vendor	Free allowance as published	Checked
SimpleVerifier	100 checks per Google account, one time, no card	Our own plan
ZeroBounce	100 validations a month on its Freemium plan	19 Oct 2026
Kickbox	100 verifications	23 Oct 2026
MillionVerifier	100 free credits on a new account, no card	23 Oct 2026
DeBounce	100 free credits on signup, no card	23 Oct 2026
Emailable	250 free credits for every new account	23 Oct 2026
Scrubby	200 free credits for every new account, no card	3 Nov 2026
Reoon	20 verifications a day, plus 100 instant credits at sign-up	30 Oct 2026
Hunter	50 credits a month on the Free plan (a verification costs 0.5 credits)	23 Oct 2026

A few honest observations. ZeroBounce's recurring 100 a month is better than our one-time 100 if all you ever do is check a small batch each month. Emailable and Scrubby give more on day one. Reoon's daily 20 suits someone who checks a few leads a day. Where we are different is not the number but the combination: the full mailbox check, no card, and a flat monthly price when you outgrow it.

Use the 100 to test the verifier, not just your list

A free allowance is a trial. The point is to decide whether you trust the verifier before you hand it a large file. Spend about a third of the 100 on a test set:

• three or four addresses you know are valid, such as your own mailboxes on different providers,
• three or four you know are dead, such as a former colleague's address that bounced last quarter,
• a few at domains you know are catch-all,
• an address with a typo domain.

Then spend the remainder on a spread of your real list. If a verifier marks a dead address valid, that is a red flag worth knowing before you pay anyone. Our post on what accuracy claims actually mean explains why you should test it this way instead of trusting a headline number.

What 100 checks cannot tell you

• Your whole list's bounce rate. A sample of 100 is a rough indication, nothing more. If 12 of 100 rows come back invalid, a list of 20,000 likely has many dead rows, but the exact count needs the full run.
• Rare cases. Catch-all domains, greylisting and unusual mail servers show up in small numbers. You will see some in 100 rows, not all kinds.
• Speed at scale. One hundred rows says little about how long 50,000 will take.

When paying makes sense

Stay free if you check a small batch once. Pay when any of these is true:

• Your list is larger than the free total. Verifying 5,000 rows is not a free-tier job on any vendor's allowance in the table.
• You verify every month. A one-time 100 is gone after the first batch. A monthly plan covers each new list.
• You need the API. API access is on paid plans, not the free checks. See the free email verification API post.
• You re-check the same list before each send. Re-checks are where per-credit packs add up and a flat plan does not. Confirmed results are cached for 14 days, so re-checking an overlapping list is not billed again.

The plans, on the pricing page: Starter is $9 a month for 2,500 emails, and Pro is $39 a month, the first 100,000 checks a month at full speed, then slower, never cut off.

If you only have one large list to clean once, a prepaid pack from another vendor can cost less than a month of Pro. We would rather you know that than find it out afterwards. The ZeroBounce small-list comparison puts the pack prices side by side.

Bottom line

You can verify 100 emails free: sign in with Google, paste or upload, download the CSV. Use the first few on addresses you know the answer to, the rest on a spread of your real list, and decide from the result. If the check earns your trust, Pro is $39 a month. If it does not, you lost nothing but ten minutes.
