The Scenario
Your list hygiene process just finished. The output is a Google Sheet with 400 rows — emails flagged as hard bounces, spam complaints, or explicit opt-outs from the last three campaigns. Every one of them needs to come off the Main-Newsletter list in Laposta before the next send.
You found out about this at 4 PM. The send is scheduled for tomorrow morning.
The bad version:
- Open Laposta, search for the first email, find the subscriber record, click unsubscribe or delete, confirm
- Repeat 400 times
- Lose count somewhere around row 80, start second-guessing whether you got them all
- Finish at 7 PM and still not be confident the list is clean
This is the kind of work that makes people consider whether they went into the right career. Four hundred records, each requiring four clicks. Nobody should have to do that.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet. It reads the column of flagged emails, calls the Laposta API for each one, and removes or unsubscribes them from the list you specify. If an email isn't found on the list, it skips it without stopping.
Delete every email in column A of Sheet1 from Laposta list Main-Newsletter — if an email is not found, skip it and continue rather than stopping
What You Get
- All 400 emails processed against the Main-Newsletter list
- Found and deleted records have REMOVED written to column B
- Emails not found on the list have NOT FOUND written to column B — no errors thrown, processing continues
- Final summary in the SheetXAI sidebar: 387 removed, 13 not found
What If the Data Is Not Quite Ready
You want to unsubscribe rather than fully delete the records
For each email in column A of Sheet1, update the member status to unsubscribed on Laposta list Main-Newsletter — write the outcome (updated/not found) to column B
Your sheet has both hard bounces and opt-outs and you want to handle them differently
For each row in Sheet1 where column B is hard_bounce, delete the member from Laposta list Main-Newsletter; for rows where column B is opt_out, set status to unsubscribed instead — write result to column C
Some emails appear more than once in the column and you want to avoid duplicate API calls
Deduplicate column A in Sheet1, then remove all unique emails from Laposta list Main-Newsletter — write REMOVED or NOT FOUND to column B next to the first occurrence of each email
Validate, remove, and flag remaining risk in one shot
In Sheet1, skip any row where column A does not contain the @ symbol; for all valid emails, remove from Laposta list Main-Newsletter; write REMOVED/NOT FOUND to column B; then count remaining active members on the list and write the count to cell D1
The list is clean before the morning send, and you have a written record of what happened.
Try It
Get the 7-day free trial of SheetXAI and open your bounce or opt-out sheet, then ask it to remove that column of emails from the specific Laposta list by name. You can follow up by asking it to pull the updated active subscriber count back into the sheet.
