The Scenario
A deliverability consultant has identified a problem. The client's "Main Newsletter" Klaviyo list has 600 long-inactive emails dragging down the engagement rate — addresses that have not opened an email in over a year and are hurting sender reputation. The removal list is in a Google Sheet: one email per row in column A. The goal is to remove them from the list without suppressing them entirely, so they can still receive transactional emails.
The bad version:
- Log into Klaviyo, navigate to the "Main Newsletter" list, and look for a bulk removal option — find that removing specific profiles from a list requires using the list management API, not the UI.
- Export the current list membership, build a formula to identify which rows match the removal sheet, check each one off, and then try to batch-remove through the admin panel, which does not support bulk removal directly.
- Spend two hours on a task that should take ten minutes, and push the list cleanup to next week when there is "more time."
Deliverability is not a next-week problem. The next campaign goes out in four days.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads the removal list and calls Klaviyo's list membership removal endpoint in batches — up to 1,000 per call.
Remove all email addresses in column A from the Klaviyo list named "Main Newsletter"
What You Get
- All 600 emails are submitted to Klaviyo's list member removal endpoint in batches.
- Profiles are removed from the list but not suppressed — they remain available for transactional sends.
- Any email address that was not a member of the list is noted in the output rather than causing an error.
What If the Data Is Not Quite Ready
You need a status log for each row
Read the "Inactive Subscribers" sheet and remove every email in column A from Klaviyo list ID list456, writing "REMOVED" or "NOT_FOUND" in column B
The removal list needs to be deduplicated before processing
Deduplicate column A by email address, then remove all unique emails from the Klaviyo list named "Main Newsletter" and write the removal status into column B
You want to remove from multiple lists simultaneously
Remove all emails in column A from both the Klaviyo list named "Main Newsletter" and the list named "Promotional Offers" — write the status for each list into columns B and C respectively
Full list cleanup with deliverability reporting in one pass
Deduplicate column A, remove all unique emails from Klaviyo list "Main Newsletter", write "REMOVED" or "NOT_FOUND" into column B, write the date of removal into column C for successfully removed addresses, and output a summary showing total removed, total not found, and the new list size estimate
The list is clean before the campaign goes out. Deliverability stays intact.
