Clean your email list where it already lives. ClearBounce checks every address in a column of your spreadsheet and writes the result next to it, so you can filter out bad addresses before your next campaign, import or outreach. HOW IT WORKS 1. Open Extensions > ClearBounce Email Verification > Verify emails. 2. Connect your ClearBounce API key (free account, free credits included). 3. Pick the email column and click Verify. WHAT YOU GET FOR EVERY ADDRESS - Status: Deliverable, Risky, Undeliverable or Unknown - Reason, plus a 0-100 quality score - Free provider, role account (info@, sales@), disposable mailbox and catch-all domain flags - "Did you mean" suggestion for typos such as gmial.com BUILT FOR REAL LISTS - Verifies tens of thousands of rows; large lists run on ClearBounce's servers, so you can keep working or close the sidebar - Duplicates, blank cells and malformed addresses never use credits - Re-run a sheet after adding rows: only the new rows are verified - Optional color-coding of the status column PRIVACY The add-on only accesses the spreadsheet you open it in, and only sends the email addresses in the column you choose. Your API key is stored privately in your Google account, never in the sheet. PRICING Pay as you go from $4 per 1,000 verifications. Credits never expire. No subscription needed.
