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 the segment before next week's prospecting campaign sends. The list is in an Excel workbook on OneDrive, column A is email, column B is segment name.
The bad version:
- You ask the developer to write a removal script
- She pulls the workbook, writes the script, discovers that segment removal requires the contact ID not the email, so she chains two API calls per row
- The script runs and reports "40 removed" but does not tell you that five of those contacts were never in the segment
- Next week's prospecting email goes to five customers who already converted.
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 Excel workbook that reads the mapping, resolves the IDs in Resend, and fires the removals for you.
Open the SheetXAI sidebar and type:
Read the RemoveFromSegments tab in this workbook where A=email and B=segment name. For each row, remove that contact from the specified Resend segment and log "removed" or the error in column C.
SheetXAI iterates through all 40 rows, resolves contact and segment IDs, fires the removal for each one, and logs the result in column C. Forty rows, forty results, column C tells you exactly what happened.
What You Get
A completed RemoveFromSegments tab:
- Columns A and B — email and segment name, 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. You investigate the five, confirm they are already clean, and move on.
The 35 legitimate removes are done. Next week's prospecting campaign goes to people who need it.
What If the Data Is Not Quite Ready
Conversion lists from CRM 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." Resend is case-sensitive.
Normalize the segment names in column B to title case before looking them up in Resend. For each row, remove the contact from the matched segment and write the result in column C.
When some contacts need to be removed from multiple segments
The workbook has one row per contact, but some converted customers are in both "Active Prospects" and "Trial Users."
For each row 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 very recent converts
Column C has a "converted date" and you only want to remove contacts who converted more than 7 days ago.
Filter the RemoveFromSegments tab to rows where column C (converted date) is more than 7 days ago. Remove each filtered contact from the segment in column B and write the result in column D.
When the workbook has duplicates and contacts from multiple segments
The list came from three conversion reports merged together.
Look at the RemoveFromSegments tab. 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 not in that segment, write "not in segment" in column C. If successful, write "removed." If it fails for another reason, write the error.
The pattern: the ID resolution, the removal, and the error logging happen in one prompt.
