Why test an email address before you send?

• Cut your bounce rate: Sending to dead or invalid addresses drives up hard bounces. Testing first keeps your list clean.
• Protect your sender reputation: Email providers watch your bounce rate closely. A clean list means your campaigns land in the inbox, not spam.
• Stop wasting sends: Every email you fire at a dead address costs you money and skews your engagement data.
• Catch typos at the source: Testing an address before you add it to your list is the fastest way to catch mistakes like "gmial.com" before they cause problems.

What does our email tester actually check?

Our tool runs several checks under the hood without ever contacting the inbox directly:

• Syntax check: Confirms the address is formatted correctly.
• Domain & MX record check: Verifies the domain exists and has mail servers set up to receive email.
• Mailbox check: Uses SMTP-level probing to test whether the specific inbox is active and accepting messages.
• Risk signals: Flags disposable addresses, spam traps, role accounts (like info@ or admin@), and catch-all domains.

Frequently asked questions

What is an email tester?

An email tester is a tool that checks whether an email address is real, active, and capable of receiving messages. It does this by verifying the address syntax, checking domain records, and probing the mail server — all without sending an actual email.

Will the person know I tested their email?

No. Our tool uses stealth verification, which means we test the address at the server level without ever sending a message to the inbox. The owner of the address will have no idea a check was performed.

Can a tested email still bounce?

Hard bounces (permanent failures due to non-existent addresses) are what our tool eliminates. Soft bounces — temporary issues like a full inbox or a server outage — can still happen occasionally, since those conditions change after the test is run.

What's a catch-all email address?

A catch-all server accepts every email sent to its domain, even if the specific mailbox doesn't exist. Our tool flags these as risky, because there's no way to confirm whether the individual inbox is real without sending an actual message.

Can I test multiple emails at once?

This free tool tests one address at a time. If you need to test a full list in bulk, sign up for a free account — you'll get 100 free verifications every month and access to our bulk email verification tool.

How accurate is the email tester?

Our accuracy rate is 99%. The only edge cases that can affect results are catch-all mail servers and temporary server-side issues, both of which are clearly flagged in the result.
