The Scenario
You are a marketing analyst. Last month, 40 contacts in the "Active Prospects" segment converted. They are paying customers now. You need to remove them from "Active Prospects" so they do not keep receiving prospecting messages.
You have a Google Sheet with 40 rows. Column A is the contact email, column B is the segment name ("Active Prospects" for all of them).
The bad version:
- You ask the developer to write a removal script
- She looks up the Resend API docs, discovers that segment removal requires the contact ID, not the email, so she has to chain two calls per row
- The script runs, logs "40 removed," but five of the removes silently failed because those contacts were never in the segment in the first place
- You send next week's prospecting email to five converted customers anyway.
The fast version is one prompt with a logged result per row.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet that reads the mapping, resolves the IDs in Resend, and fires the removals for you.
Open the SheetXAI sidebar and type:
For each row in the SegmentRemovals sheet (A=contact email, B=segment name), remove that contact from the specified Resend segment. Write "removed" or the error message into column C for each row.
SheetXAI iterates through all 40 rows, resolves contact and segment IDs from Resend, fires the removal for each one, and logs the result in column C. Forty rows, forty results, column C tells you exactly what happened for each one.
What You Get
A completed SegmentRemovals sheet:
- Column A — email addresses, untouched
- Column B — segment names, untouched
- Column C — "removed" or the Resend error message for each row
You know immediately which five were not in the segment, because column C says "contact not in segment" for those rows rather than a vague success count. You investigate the five, confirm they are already handled, and move on.
The 35 legitimate removes are done. Next week's prospecting email goes to people who actually need it.
What If the Data Is Not Quite Ready
Segment removal lists from converted-customer exports are rarely perfectly clean. SheetXAI handles the issues in the same prompt.
When the segment name in column B varies by capitalization
Some rows say "Active Prospects," others say "active prospects." The Resend API is case-sensitive.
Normalize the segment names in column B to title case before looking them up in Resend. For each row in SegmentRemovals, remove the contact from the matched segment and write the result in column C.
When some contacts appear in multiple segments and you want to remove from all of them
The sheet has one row per contact, but some contacts need to be removed from both "Active Prospects" and "Trial Users."
For each row in SegmentRemovals where column B lists multiple segments separated by a comma, remove the contact from each segment listed. Write the result for each removal in column C, separated by semicolons.
When you want to skip contacts who converted very recently
Column C has a "converted date" and you only want to remove contacts who converted more than 7 days ago, giving recent converts time to be onboarded first.
Filter the SegmentRemovals sheet to rows where column C (converted date) is more than 7 days ago. For each filtered row, remove the contact from the segment in column B and write the result in column D.
When the sheet has duplicates, non-segment-members, and contacts from multiple segments
The list came from three different conversion reports merged together. You want everything handled cleanly.
Look at the SegmentRemovals sheet. Remove duplicate rows where both column A and column B are identical. For each unique row, remove the contact from the specified Resend segment. If the contact is not in that segment, write "not in segment" in column C. If the removal succeeds, write "removed." If it fails for another reason, write the error.
The pattern: the ID resolution, the removal, and the error logging all happen in one prompt.
