The Scenario
You are a developer advocate. Your team shipped a private beta last Friday. You have 80 beta testers in a Google Sheet, column A holds their email addresses, column B holds their individually generated invite codes.
The task is simple: send each person a personalized welcome email via Resend. The email should include their invite code in the body. Log the Resend email ID back into column C so you have a delivery record.
The bad version:
- You write a Node script to loop through the sheet rows
- You spend twenty minutes wrestling with the Google Sheets API to authenticate
- The script sends fine in dev, breaks in prod because the credentials are wrong
- You fix it, re-run, discover twelve rows had stale emails from an old export
- You remove the bad rows manually, re-run, wait for confirmation
- You ship the beta invite email four hours after you planned to.
The fast version is one prompt, no script.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet that reads the data and calls the Resend API for you, so you do not have to write or run any code.
Open the SheetXAI sidebar and type:
For each row in the BetaTesters sheet (A=email, B=invite code), send a personalized Resend email from hello@myapp.com with subject "Your beta invite" and a body that says "Welcome to the beta. Your invite code is [invite code]. Use it at app.myapp.com to get in." Write the Resend email ID into column C for each row.
SheetXAI reads every row, sends a Resend email per recipient with that row's invite code in the body, and writes each returned email ID back into column C. Eighty rows. Eighty sends. Eighty IDs logged.
What You Get
A completed sheet with:
- Column A — original email addresses, untouched
- Column B — invite codes, untouched
- Column C — Resend email IDs, one per row, written in as each send completes
The delivery record is built as the sends go out, not reconstructed from a log file afterward. If anything bounces later you have the email ID to look it up in Resend directly.
Want a different body? Tell SheetXAI to use a specific HTML template, or to pull the first name from column D and open the email with "Hi [first name]." It adjusts the send per row.
What If the Data Is Not Quite Ready
Most real beta tester lists are not as clean as the scenario above. SheetXAI can handle cleanup and the send in the same prompt.
When some rows have duplicate email addresses
You exported from two different signup forms and some addresses appear twice with different invite codes.
Deduplicate the BetaTesters sheet by column A, keeping the row with the longer invite code. Then send the personalized Resend email to each unique address and log the email ID in column C.
When some invite codes are blank
A few rows in column B are empty because those testers were added manually and nobody assigned a code.
For each row in BetaTesters, if column B is blank, write "NO_CODE" into column B. Then send the Resend welcome email to every row. For rows with NO_CODE in the body, substitute a note that says "Your invite code will follow in a separate email." Log all email IDs in column C.
When you only want to send to testers who have not been contacted yet
Column C already has email IDs in some rows from a partial run last week. You want to skip those.
For each row in BetaTesters where column C is blank, send the personalized Resend email and write the email ID into column C. Skip any row that already has a value in column C.
When you want to send, clean, and log in one shot on a raw export
You just exported from your beta signup tool. The sheet has raw data including duplicates, blank invite codes, and a mix of formatted and unformatted emails. You want it all handled at once.
Look at the BetaTesters sheet. Remove duplicate rows by email (keep first). Normalize all email addresses to lowercase. For rows missing an invite code in column B, write "PENDING" in column B. Then send each row a personalized Resend email from hello@myapp.com with their invite code in the body (using "Your invite code is coming soon" if the code is PENDING). Log the Resend email ID in column C and any send errors in column D.
The pattern: instead of cleaning the list first and then scripting the send, you ask for both in one prompt. The cleanup and the API call happen together.
