The Scenario
Your DTC brand is launching eight new product lines in two weeks. Each line needs its own Sendlane mailing list before the first campaign goes out — "Spring Skincare," "Athletic Recovery," "Men's Grooming," and five others. You've already got all eight names typed out in column A of your planning sheet. Someone just asked when the lists will be ready in Sendlane.
This is the third time you've set up product-line lists for a launch. The previous two times you did it by hand in the Sendlane UI, one list at a time, and then copied the IDs into the sheet afterward.
The bad version:
- Click "Create list" in Sendlane, type the first product name, save, copy the list ID from the resulting URL, paste it into column B row 2.
- Repeat seven more times, being careful not to mis-type any names that already exist elsewhere in the account.
- Go back into the sheet, notice you forgot one, return to Sendlane, create it, come back.
Eight lists sounds like twenty minutes. It's closer to forty once you account for navigation, typos, and the one you forgot. And you're the person who's supposed to be writing the campaign briefs, not clicking through account setup screens.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads the list names already in your Google Sheet and tells Sendlane to create a mailing list for each one — writing each returned list ID back into the sheet as it goes.
Create a new Sendlane mailing list for each name in column A of this sheet and write the returned list ID into column B on the same row.
What You Get
- Each name in column A triggers a Sendlane list creation.
- The Sendlane-assigned list ID is written into column B on the matching row.
- If a name fails — say, because a list with that name already exists — the error appears in column B instead, so you know which rows need attention without auditing the whole column.
- The entire batch runs in one pass, not eight separate operations.
What If the Data Is Not Quite Ready
Some names in the column might already exist as lists in Sendlane
For each name in column A of my sheet, try to create a Sendlane mailing list. If creation succeeds, write the list ID in column B. If Sendlane returns an error indicating the list already exists, write "already exists" in column B. If it fails for any other reason, write the error message in column B.
You need to log both the ID and the full list name Sendlane assigns
Create a Sendlane mailing list for each name in column A of this sheet. Write the returned list ID into column B and the list name as confirmed by Sendlane into column C, starting at row 2.
The list names need a prefix before they go into Sendlane
For each name in column A of my sheet, create a Sendlane mailing list with the name "2026 Launch — " followed by the value in column A. Write the returned list ID into column B.
Create the lists, then confirm them all in one audit pass
Create a Sendlane mailing list for each name in column A of this sheet, write the returned list ID in column B, and then — after all lists are created — fetch all Sendlane lists and write a count of total lists now in the account into cell D1 as a confirmation.
One prompt creates the lists, logs the IDs, and validates the total count without a second round of clicking.
