Overview
Check an email address without leaving Gmail™.
Email Checker & Verification by Easy Email Verification helps you identify invalid addresses and review delivery risks before contacting a new recipient.

GET STARTED
1. Install the add-on and open Gmail. Refresh Gmail if the icon does not appear.
2. Open Email Checker in the Gmail side panel.
3. The add-on connects your Google account to Easy Email Verification. If prompted, click Connect. You do not need to copy an API key.
4. Paste an email address and click Verify.
5. Review the result, its reason and the risk indicators before deciding what to send.

WHAT THE CHECKS COVER
• Email syntax, domain and MX records.
• Mail server connectivity and mailbox acceptance when the receiving server allows verification.
• Disposable addresses and catch-all domains.
• Role-based addresses, free email providers and suggested corrections for common domain typos.

UNDERSTAND THE RESULT
• Valid: the address passed the applicable checks. Review the risk indicators as well.
• Invalid: a check failed or the receiving server rejected the mailbox. Correct or confirm the address before sending.
• Unknown: the service could not reach a reliable conclusion. Unknown does not mean invalid; try again later.
Catch-all domains can accept mail for addresses that do not exist, so an individual mailbox cannot be confirmed.

HISTORY, CREDITS AND YOUR ACCOUNT
Review recent checks in History. Open Balance when you want to see your available credits. Open the dashboard to manage your account, credits and connected apps.
For complete lists, use the separate Easy Email Verification Google Sheets™ add-on or the dashboard's bulk verification tool.

ACCOUNT AND PRICING
Installation is free. Verification requires an Easy Email Verification account and uses its available allowance or credits. Paid credits and plans are available when you need more. Check your account dashboard for the current allowance, balance and prices.

IMPORTANT LIMITS
Verification helps assess risk; it does not guarantee delivery, ownership, identity or permission to contact a recipient. Mailbox checks do not send a message to the address being checked. Results can be inconclusive when a receiving server blocks or limits verification.

Available in English, Portuguese, Spanish, Italian, German and French.

Useful for double-checking old contacts. If I haven’t emailed someone in a while, I can check the address before reaching out again.

The disposable email check is the feature I find most useful. It gives me a reason to double-check an address before relying on it for follow-up.

The results are easy to read. I especially like that it flags catch-all domains, so I know when an individual address couldn’t be confirmed.
