The Scenario
You are an e-commerce developer. Last night, 95 orders came in during the flash sale. Every customer is waiting for their order confirmation email.
The order data is in an Excel workbook: column A is email, column B is order number, column C is order total.
Resend's batch endpoint handles up to 100 emails in a single API call. One call, all 95 confirmations, done. The alternative is a script with retry logic you do not want to write at 9 AM.
The bad version:
- You export the tab as CSV and write a script to shape the batch payload
- Resend's batch schema is slightly different from the individual send endpoint and you spend thirty minutes in the docs
- You hit a 422 on the first run because one row has a null total
- You handle the null, re-run, realize the workbook was on SharePoint and the export you used was two hours stale
- The confirmations go out hours after the orders closed and three customers have already emailed support.
The fast version is one prompt directly from the workbook.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook that reads the data and calls Resend's batch endpoint for you, shaped correctly the first time.
Open the SheetXAI sidebar and type:
Read all rows in the OrderConfirmations tab (A=email, B=order number, C=total). Send them all as a single Resend batch email, one per row, from orders@mystore.com with subject "Your order is confirmed" and a body that includes the order number and total. Log the batch response in cell F1.
SheetXAI reads all 95 rows, constructs the batch payload, fires the single Resend batch API call, and writes the response (including batch ID and timestamp) into cell F1. Ninety-five confirmation emails, one API call, one log entry.
What You Get
A completed send logged in the workbook:
- 95 confirmation emails sent in one Resend batch call
- Cell F1 — the full batch API response including batch ID and timestamp
- Each email personalized with the order number and total from its row
One call, one log entry, done. If the batch fails, the full error response is in F1 so you know immediately what happened.
What If the Data Is Not Quite Ready
Order exports are rarely perfectly clean. SheetXAI handles the data and the batch send together.
When order totals are missing for some rows
A few rows in column C are blank because the payment captured after the export ran.
For rows in the OrderConfirmations tab where column C is blank, substitute "pending" for the total in the email body. Then send all rows as a single Resend batch and log the batch response in cell F1.
When the batch needs to be split because you have more than 100 rows
The export has 190 orders and the batch endpoint caps at 100.
Read the OrderConfirmations tab. Split into two batches of up to 100 rows each. Send the first batch via Resend and write the batch ID and row range into cell F1. Send the second batch and write its batch ID and row range into cell F2.
When you want to preview the payload before sending
You want to confirm the payload looks right before the API call goes out.
Read all rows in the OrderConfirmations tab (A=email, B=order number, C=total). Build the Resend batch payload and write the full JSON into column E, one row per email object. Do not send yet.
When you need to clean, build, send, and log in one operation
The tab is a raw export with a header row, some null totals, and a few non-email values in column A.
Look at the OrderConfirmations tab. Remove the header row if present. Drop rows where column A is not a valid email address. For rows where column C is blank, substitute "N/A." Then send all valid rows as a Resend batch from orders@mystore.com, subject "Your order is confirmed," with order number and total in the body. Write the batch response and timestamp into cell F1.
The pattern: the cleanup and the batch send happen in one prompt. No script, no CSV export, no separate steps.
