Verify and clean email lists without leaving Google Sheets™. Email Checker & Verification by Easy Email Verification helps you identify invalid addresses and review delivery risks directly in your spreadsheet.

START WITH AN EMPTY SHEET OR AN EXISTING LIST
1. Install the add-on, open a spreadsheet and click Email Checker in the right side panel. Refresh Sheets if the icon is missing.
2. Connect your Google account and complete authorization if prompted. No API key to copy.
3. Add an Email header in row 1 and enter addresses from row 2, or choose Create a template.
4. Open Verify, choose the email column or use your current selection, and refresh the panel after changing your data.
5. Check the selected range, unique email count, estimated credit usage and output columns. Click Review verification.
6. Review the counts for selected rows, empty cells, invalid formats and duplicates. Choose Confirm processing to start.
7. When the run is completed, open the results in your spreadsheet.

VERIFY UNIQUE CONTACTS, KEEP YOUR ORIGINAL ROWS
Empty cells, malformed addresses and duplicate occurrences are excluded from submission. Repeated addresses are verified once per run, and their saved results are applied to matching source rows. The preview helps you see the unique count and estimated credit usage before confirming. For example, 17 rows with eight duplicate occurrences contain nine unique contacts.

RESULTS BESIDE YOUR EMAILS
View 13 columns including Email, Safe To Send, Result, Reason, User, Domain, Disposable, Accept All, Role, Free, MX information and a suggested correction when available.
• Valid: the address passed the applicable checks; review the other risk indicators as well.
• Invalid: a check failed or the receiving server rejected the mailbox. Correct or confirm the address before sending.
• Unknown: a reliable conclusion was not possible. Unknown does not mean invalid; try again later.
Catch-all domains can accept mail for nonexistent addresses, so an individual mailbox cannot always be confirmed.

LISTS, HISTORY AND YOUR ACCOUNT
Large lists are processed in sequential batches, subject to available credits and service limits. Submitted bulk jobs can continue on the server while the browser is closed. Reopen Verify for current status and result synchronization; History shows saved activity and links to results.
After completion, Create safe contact list can create a separate sheet containing unique contacts marked Safe To Send. Account shows your connection, credit balance and language setting. The interface supports English, Portuguese, Spanish, Italian, French and German.

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

DATA USE AND VERIFICATION LIMITS
Selected unique email addresses are sent to Easy Email Verification for checking. Recovery snapshots and results are stored in hidden tabs in the source spreadsheet; collaborators with access to the spreadsheet can access those tabs. Do not delete recovery tabs while a job is pending.
Verification assesses risk; it does not guarantee delivery, identity, ownership or permission to contact a recipient. Mailbox checks do not send an email to the address being checked. A receiving server can block or limit verification.
