The Scenario
You're a deliverability consultant and you've just been handed 200 subscriber IDs from a client's Sender account. The client is planning a re-engagement campaign, but they don't know which of those subscribers are still active, which have unsubscribed, and which have bounced. Before the campaign gets built, they want a list-health report.
The IDs are in an Excel workbook. The data is in Sender. Getting from one to the other means 200 individual API lookups or 200 clicks through a dashboard neither of you has had a reason to map to a spreadsheet before.
The bad version:
- Export the Sender subscriber list as a CSV, open it in another worksheet, do a VLOOKUP against the 200 IDs, and discover the exported CSV uses email as the primary key but your audit list uses subscriber IDs — so the lookup returns empty.
- Use Sender's search to pull each subscriber by ID one at a time, copy the status and group memberships into the workbook manually, and realize around row 40 that this is going to take most of the afternoon.
- Give up halfway and write "status unknown" for the remaining 120 rows, which means the re-engagement list going to the client is half-complete.
The report is supposed to land in the client's inbox by end of day. A half-complete audit is not a deliverable.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads your column of subscriber IDs, fetches each record from Sender, and writes the status, email address, and group memberships back into adjacent columns — all from one prompt.
Look up each subscriber ID in column A from Sender and fill in email address, subscription status, and all custom field values into adjacent columns in this Excel workbook.
SheetXAI looks up each ID, pulls the record, and fills in what it finds. Subscribers with a status of "unsubscribed" or "bounced" surface clearly so you can flag them. Group memberships land as a comma-separated list in the next column.
What You Get
- Email address for each subscriber ID.
- Current subscription status — active, unsubscribed, bounced, or the specific status string Sender returns.
- Comma-separated list of group names the subscriber belongs to.
- Rows where the subscriber ID doesn't exist in Sender get "not found" in the email column so you can flag those for the client separately.
- The 200-row audit runs in one pass.
What If the Data Is Not Quite Ready
You also need each subscriber's custom field values for the audit
For each subscriber ID in column A, fetch the subscriber record from Sender and write their email, status, all group names, and all custom field values into columns to the right.
Some IDs in column A have trailing spaces or are formatted as floats instead of integers
For each value in column A, strip whitespace and convert to a clean integer, then look up the subscriber in Sender and write email, status, and group names into the adjacent columns.
You want to flag bounced and unsubscribed subscribers in red directly in the workbook
For each subscriber ID in column A, fetch their email, status, and group names from Sender and write them into adjacent columns. Then highlight the entire row in red for any subscriber whose status is "bounced" or "unsubscribed."
The full kill chain — clean IDs, fetch records, flag health issues, and generate a summary for the client
In the Audit worksheet, strip whitespace from all values in column A and remove duplicate IDs, then look up each remaining subscriber in Sender and write email, status, and group names into columns B, C, and D. Highlight bounced rows in red and unsubscribed rows in yellow. Write a summary into cell F1: total IDs checked, active count, unsubscribed count, bounced count, and not-found count.
One prompt produces the deliverable. You hand the client a complete audit, not a status-unknown-for-120-rows draft.
