The Scenario
A multi-brand retailer is launching five product lines this quarter. Each one gets its own Laposta mailing list with a dedicated notification email and a short description. The list of names and details is in a Google Sheet — five rows, each with the list name in column A, the notification email in column B, and a description in column C.
Clicking through Laposta's create-list flow five times means five separate form submissions, five confirmation screens, five chances to paste the wrong notification email into the wrong list.
The bad version:
- Open Laposta, click Create List, type the first name, paste the notification email, add the remark, save
- Navigate back to the list overview
- Repeat four more times
- Check that all five were created correctly by clicking into each one, because you're not confident the copy-paste on lists three and four was right
The sheet already has everything. Treating it as a reference document you're transcribing into a form is a waste of the work you already did.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet. It reads the list definition table and creates each Laposta mailing list via the API, writing the new list ID back to the sheet for reference.
Create a new Laposta mailing list for each row in Sheet1 — column A is the list name, column B is the notification email, column C is the remark/description
What You Get
- Five new Laposta mailing lists created in the account, in the order they appear in Sheet1
- List name, notification email, and remark applied as configured
- New Laposta list ID written to column D for each row
- Any creation failures (e.g., a list name that already exists) flagged in column E with the error message
What If the Data Is Not Quite Ready
Some list names have trailing spaces or inconsistent capitalization
Trim whitespace from column A and apply title case, then create one Laposta mailing list per row using the cleaned name from column A, notification email from column B, and remark from column C
You want all five lists to share the same notification email
Create a Laposta mailing list for each row in Sheet1 using column A as the name and column C as the remark, but use notify@company.nl as the notification email for all lists regardless of column B
Your sheet has blank rows between entries that should be skipped
Skip any row in Sheet1 where column A is blank, then create one Laposta list per remaining row using column A as name, column B as notification email, column C as remark — write the new list ID to column D
Validate, create, and prepare the next step in one shot
Check that every email in column B of Sheet1 contains the @ symbol — flag invalid emails in column E; for all valid rows, create the Laposta mailing list and write the new list ID to column D; then write a summary of lists created versus skipped to cell G1
The five lists are in Laposta before the end of the morning, each with the right configuration.
Try It
Get the 7-day free trial of SheetXAI and open your list definition sheet, then ask it to create one Laposta mailing list per row. You can follow up by asking it to scaffold custom fields on each newly created list using a second definition tab.
