The Scenario
An agency manages email marketing for ten regional clients. Each client is getting a new dedicated Mailercloud list for a seasonal campaign — different name, different target region, all managed under the same Mailercloud account. The list names and descriptions are already documented in a master Google Sheet: column A has the list name, column B has a short description.
Someone has to create all ten lists in Mailercloud. The UI creates one at a time. You type the name, add a description, save, go back to the list view, click new, type again.
The bad version:
- Open Mailercloud, navigate to the lists panel, click "Create new list", type the first list name from the sheet, paste the description, save
- Go back to the lists view, click "Create new list" again, type the second list name, paste the second description, save
- Lose your place after the fifth one because someone pinged you on Slack, go back to the sheet, figure out which row you were on, continue
Ten lists is a full lap around the UI. Fifty lists would take a morning. The sheet already has everything — it just needs to land in Mailercloud.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads your list definition table, creates each Mailercloud list in sequence, and writes back the new list ID so you have a live record of what was created.
For each row in this sheet, create a new Mailercloud contact list using the list name in column A — write the new list ID into column B when created
What You Get
- SheetXAI reads each row and makes a separate Mailercloud API call to create the list
- Column B gets the new Mailercloud list ID written back when each list is created successfully
- If a creation fails — because the name is a duplicate or the request errors — you'll see which rows didn't complete so you can address them individually
- All ten lists are created without touching the Mailercloud UI once
What If the Data Is Not Quite Ready
You also want a CREATED/FAILED status column alongside the ID
For each row in this sheet, create a new Mailercloud contact list using the name in column A — write the new list ID into column B and CREATED or FAILED into column C for each row
The sheet has a mix of rows — only create lists where column D says "launch"
For each row in this sheet where column D says "launch", create a new Mailercloud contact list using the name in column A — write the new list ID into column B and CREATED into column C
You want to include a description for each list from column B
For each row in this sheet, create a new Mailercloud contact list using the name in column A and the description in column B — write the new list ID into column C and CREATED or FAILED into column D
Kill chain: validate names, create lists, write IDs and statuses, summarize
For each row in this sheet, check that column A is not blank — if it has a name, create a new Mailercloud contact list with that name and the description in column B, write the list ID into column C and CREATED into column D — if column A is blank, write SKIPPED into column D — then write the total number of successfully created lists into cell E1
One prompt. Validation, creation, writebacks, and a count all happen together.
