The Scenario
You're an email marketing manager at a B2C retailer. You've got a Google Sheet with roughly 50,000 customer emails — a mix of purchase signups, contest entries, and imported contacts from two years of list swaps. The promotional campaign going out Thursday is your biggest send of the quarter.
Your deliverability consultant told you last month that your bounce rate from the previous campaign was 4.2%. That number is circling in your head.
The bad version:
- Export the sheet's email column as a CSV, upload it to EmailListVerify's dashboard, wait for the bulk job to finish (somewhere between 20 minutes and a few hours for a list this size)
- Download the results file, open it in a second spreadsheet tab, try to align the "email" column in the results with the original sheet's row order — which hasn't stayed sorted since someone added 800 new contacts last week
- Paste verification statuses back row by row, discover three columns are misaligned, redo the paste, repeat
Fifty thousand addresses means no one is doing this by hand and getting it right the first time. And you have a campaign to finalize, not an afternoon to spend on data plumbing.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads your data, connects to EmailListVerify, submits the list as a bulk verification job, polls until the job finishes, and writes every result back to the right row — all from a single prompt.
Upload all email addresses from column A of the "Customer List" tab to EmailListVerify for bulk verification, poll until the job completes, then write each email's verification status (valid/invalid/catch-all/unknown) back to column B
What You Get
- Column B fills with a status for every row:
valid,invalid,catch-all, orunknown - Rows stay aligned to the original email column — no realignment step
- If a row had a blank email cell, SheetXAI flags it rather than sending an empty string to the API
- When the job is still processing, SheetXAI waits and checks back rather than returning a partial result
What If the Data Is Not Quite Ready
The list has duplicates and you want to verify only unique addresses
Deduplicate the emails in column A of the "Customer List" tab, submit only the unique addresses to EmailListVerify for bulk verification, then write the status back to column B for every row — including duplicate rows that matched a verified address
Some emails have leading or trailing spaces from a CSV import
Trim whitespace from every email in column A of the "Customer List" tab before submitting them to EmailListVerify for bulk verification, then write the cleaned email back to column A and the verification status to column B
The list is split across three tabs and you need a unified result
Combine all email addresses from the "Purchases," "Contests," and "Imports" tabs into a single pass through EmailListVerify's bulk verification, then write each result back to a "Status" column in the tab where the address originally appeared
Clean the list and separate the valid addresses in one shot
Verify all emails in column A of the "Customer List" tab using EmailListVerify, write the status to column B, then copy all rows where status is "valid" to a new tab called "Verified Sends" so I have a clean list ready to export
Ask for the verification and the filtering in one prompt — SheetXAI handles both without a second pass.
