Free Email Checker
Type an address, get a real answer. This free checker runs the full TrueSendy verification — live SMTP handshake included — 15 times a day, no account, no card.
Check an email — free
Free on this page: 15 checks a day, no account needed. Signed-in accounts verify with credits — and unknown results are never charged.
What the result tells you
| Result | What it means | What to do |
|---|---|---|
| Valid | The mailbox exists and accepts mail | Send with confidence |
| Invalid | The mailbox does not exist | Remove it from your list |
| Catch-all | The domain accepts every address, real or not | Segment it and send carefully |
| Disposable | A temporary, throwaway inbox | Block at signup; do not mail it |
| Unknown | The mail server would not answer clearly | Re-check later — never charged on paid plans |
The six checks inside every verification
Syntax & format
Malformed addresses and typos are caught instantly, before any network check runs.
Disposable detection
Temporary inboxes from throwaway providers are flagged so they never pollute your list.
Role account detection
Addresses like info@, support@ and admin@ are identified — they behave differently from personal mailboxes.
MX & provider detection
We resolve the domain's mail servers and identify the provider behind it — Gmail, Microsoft 365, and thousands more.
Catch-all probing
A random address is tested against the domain to learn whether it accepts everything, so catch-alls are labelled, not guessed.
Live SMTP handshake
Our own Port 25 engine speaks directly to the receiving mail server and asks whether the mailbox exists.
One address is free. A whole list is cheap.
This page checks one address at a time, 15 a day. When you are ready to clean a real list, a free account gives you 100 credits, bulk verification for files up to 10,000 rows, API access and segmented downloads — and pricing after that starts at $19 for 10,000 verifications, with credits that never expire.
Simple, honest pricing
1 verification = 1 credit, credits never expire, and you are never charged for unknown results or for duplicate rows inside a bulk file.
Need a steady volume? Monthly plans run from $29/month for 25,000 credits. Or use the pricing calculator on the homepage to buy the exact number of credits you need.
Frequently asked questions
Is the free email checker really free?
Yes — 15 checks a day on this page, no account and no card. It runs the same live verification engine as the paid product, not a limited demo.
Why only 15 free checks a day?
Each check talks to a real mail server, which costs real resources. Fifteen is enough to test addresses properly; accounts get 100 free credits for bigger tests.
What happens after I use my 15 checks?
The checker resets tomorrow, or you can create a free account and keep going with 100 credits — plus bulk uploads, history and the API.
Do you store the addresses I check here?
Checks are recorded in aggregate for abuse prevention (the free tier is protected by a daily per-visitor limit), and result details are shown only to you on this page.
