How to Verify
Email Addresses
Follow this simple step-by-step guide to improve your email deliverability in seconds.
Step 1: Input Email Address
Type in the email address you want to check, then click Verify Email. The tool will run a quick set of validation checks to assess whether the address is likely to receive mail successfully.
Step 2: Review the Verification Results
Check whether an email is Valid, Risky, or Invalid, then review its format, domain and DNS records, mail server availability, and potential risks such as disposable addresses, role-based inboxes, or domain typos.
Step 3: Save as PDF (Optional)
Click Save as PDF to download a copy of the verification results for sharing, reporting, or record-keeping before sending your email.
FAQs
See more tools →What do the verification results mean?
A Valid result means the email is correctly formatted, its domain exists, and mail servers are configured to receive messages.
A Risky result means the address may still work but has warning signals, such as a role-based inbox, public email provider, disposable address, or possible domain issue.
An Invalid result means the address is unlikely to receive messages due to incorrect formatting, a missing domain, or unavailable mail servers.
Does this tool send an email to the address?
No. The verification process does not send any emails. All checks are performed in the background without contacting the recipient.
Can this guarantee that an email will be delivered?
No email verification tool can guarantee delivery. However, these checks can significantly reduce bounce risk and help you follow email deliverability best practices.
