AppRanks verdict
Generated from live marketplace data — refreshed daily
Email Verification is a highly rated Google Workspace app with a growing review traction. It is listed in the Sales & CRM category on Google Workspace Marketplace, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 323 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical Google Workspace Marketplace listing.

About Email Verification
How Email Verification works
Show full descriptionShow less
Email Verification helps you verify email addresses directly inside Google Sheets, so you can clean lead lists, reduce bounce risk, and keep outreach data organized without exporting your spreadsheet to another tool.
Use the add-on to check individual email addresses, verify small sheets immediately, or submit larger lists as background bulk jobs. Results are written back into your spreadsheet with clear statuses such as deliverable, catch-all, unknown, and not deliverable.
# WHAT YOU CAN DO
- Verify email addresses from a Google Sheet. - Clean lead lists before sending outreach or importing contacts into a CRM. - Run quick one-by-one checks for smaller sheets. - Submit larger lists as background bulk verification jobs. - See bulk job progress, last checked time, and attention-needed notices in the sidebar. - Import completed bulk results back into the original sheet when the run is finished. - Buy prepaid verification credits inside the add-on.
# HOW IT WORKS
1. Install Email Verification from Google Workspace Marketplace. 2. Open a Google Sheet. 3. Choose Extensions > Email Verification > Start. 4. Add email addresses to the first column of your sheet. 5. Click Verification in the add-on sidebar. 6. Review the Status column after the run completes.
For lists with 1 to 100 email addresses, EVADDON verifies the list immediately and fills the Status column during the run.
For lists with 101 or more email addresses, EVADDON starts a background bulk run. Bulk runs do not drip results into the sheet while they are processing. Reopen the sidebar later, open Bulk Results, and click the completed run to import results into the Status column in the same sheet. If the original sheet changed too much, EVADDON safely falls back to importing results into a new sheet.
Bulk verification supports lists up to 250,000 email addresses.
# RESULT STATUSES
EVADDON returns practical statuses for day-to-day list cleaning:
- Deliverable: the address appears safe to contact. - Deliverable (catch-all server): the domain accepts mail broadly, so the address may be higher risk. - The mail server does not respond: the server timed out, throttled the check, or did not respond clearly. - Not deliverable: the address appears invalid or unable to receive mail.
No verification service can guarantee that every future email will be delivered. Email systems change, mail servers throttle checks, and sending reputation still matters. Use verification as one layer of your deliverability workflow.
# CREDITS AND PRICING
New users receive 50 signup credits. One credit equals one email verification.
Current prepaid credit packs:
- 500 credits for $9 - 2,000 credits for $19 - 5,000 credits for $39 - 10,000 credits for $69 - 25,000 credits for $99 - 50,000 credits for $149 - 100,000 credits for $249 - 500,000 credits for $599
Credits are prepaid and do not require a subscription.
# PRIVACY AND PROVIDER USE
Email Verification uses Google account access to open the sidebar, read the active spreadsheet data you choose to verify, and write verification results back into your sheet. Email addresses submitted for verification are sent to a third-party email verification provider so deliverability checks can be performed and returned to the add-on.
Only verify email lists you have permission to use.
# SUPPORT
If you need help with installation, billing, credits, account recovery, or verification results, use the support link on this listing or contact support from the add-on website.
