The Scenario
You inherited the Sendlane account from someone who left six months ago. They created lists generously — one for every campaign, every test, every A/B variant. You're looking at 60 lists, a third of which haven't had a contact added to them in over a year. Your job before the Q3 replatform is to clean the account down to what's actually in use.
You've already done the analysis work: a column in your Excel workbook has the list IDs, and column B has "delete" or "keep" for each one.
The bad version:
- Sort by "delete," note the first ID.
- Go into Sendlane, find the list by ID (the UI sorts by name, not ID, so this involves a search), confirm it's the right one, click delete, confirm the modal.
- Return to the workbook. Note the next ID. Repeat.
- Twenty-two lists in, you accidentally delete one marked "keep" because the modal doesn't show the ID.
This isn't data analysis work. It's account janitorial work, performed in a UI not designed for bulk operations, with no audit trail.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your flagged workbook, executes the deletions against Sendlane's API, and writes the outcome back — so you end up with a complete record of what was deleted and what failed, without touching the UI.
For each list ID in column A of my Excel sheet where column B says "delete", delete that Sendlane list and write "deleted" in column C. If the deletion fails, write the error in column C instead.
What You Get
- Every row where column B is "delete" triggers a deletion request against Sendlane.
- Successful deletions get "deleted" written into column C.
- Failed deletions — already gone, permission errors, ID not found — get the specific error message in column C.
- Rows where column B is "keep" are untouched.
- You end up with a complete audit log in column C without a separate step.
What If the Data Is Not Quite Ready
The IDs in the workbook need to be validated against Sendlane before you delete anything
For each list ID in column A of my Excel sheet, check whether that list exists in my Sendlane account. Write "exists" or "not found" in column B. Do not delete anything yet.
You want to preview which list names correspond to those IDs before committing to deletion
For each list ID in column A of my Excel sheet, fetch the corresponding Sendlane list name and write it in column B. Leave column C blank.
Some of the "delete" rows have a contact count that needs to appear before you confirm
For each list ID in column A where column B says "delete", fetch the list from Sendlane, write the list name in column C and the total contact count in column D. Do not delete yet.
Do the audit, surface duplicates, and delete in one pass
Fetch all Sendlane mailing lists and write each list's ID, name, and contact count into columns A, B, and C starting at row 2. Then look through column B for any name that appears more than once. For each duplicate group, mark the list with the lower contact count as "delete candidate" in column D. Then delete every list whose column D says "delete candidate" and write "deleted" in column E, or the error if it fails.
One prompt pulls the full inventory, surfaces duplicates by contact count, and handles the cleanup — without four separate passes through the workbook.
Try It
If your Sendlane account has accumulated lists across several campaigns or team members, open the workbook where you've mapped out what to keep and what to cut, then Get the 7-day free trial of SheetXAI and let it run the cleanup.
