The Scenario
You are a franchise marketing manager. Six hundred local customer addresses are sitting in a Google Sheet — first name, last name, street, city, state, ZIP, all in separate columns. The seasonal postcard campaign was supposed to go out last Tuesday. The template is ready in Stannp. What is not ready is the gap between the sheet and the actual send.
The bad version:
- Export the sheet as a CSV, spend 20 minutes reformatting the column headers to match what Stannp's import expects, discover that three ZIP codes got formatted as numbers and lost their leading zeros, fix them, re-export.
- Upload the CSV to Stannp, wait for the recipient validation, find that 14 rows failed because the street field had trailing spaces, fix those in the sheet, export again, re-upload.
- Manually configure the campaign — select template 48291, choose the imported group, confirm the recipient count, submit the send — then open a separate tab to record the campaign ID somewhere.
Fourteen rows rejected and a total of 45 minutes of effort for what should have been a five-minute operation. Your regional VP is waiting for confirmation that the campaign went out. The constraint here is not time — it is that you cannot afford to let this slip again without a better answer.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet. It reads your data, talks to Stannp on your behalf, and writes the results back — no export, no reformatting, no manual upload.
For each row in this sheet — first name in column A, last name in column B, address1 in column C, city in column D, state in column E, zip in column F — send a Stannp postcard using template 48291 and write the returned mailpiece ID into column G.
What You Get
- A mailpiece ID written into column G for every successfully sent postcard, in the same row as the recipient data.
- Any rows where the send failed appear with the error message in column G instead of an ID, so you know exactly which addresses need attention.
- The full send log stays in the sheet — no need to cross-reference a separate Stannp report to confirm the run.
What If the Data Is Not Quite Ready
ZIP codes formatted as plain numbers
For each row in this sheet, ensure the value in column F is zero-padded to 5 digits, then send a Stannp postcard using template 48291 with first name from A, last name from B, address1 from C, city from D, state from E, and the corrected ZIP — write the mailpiece ID or error into column G.
Address data spread across multiple tabs
Join the address data from the Addresses tab (columns A through F) with the campaign flags in the Campaign tab (column B, where the value is Y), then send a Stannp postcard using template 48291 to each matched row and write the mailpiece ID into column G of the Addresses tab.
Trailing whitespace causing API rejections
Trim any leading or trailing whitespace from columns C through F for every row in this sheet, then send a Stannp postcard using template 48291 — first name from A, last name from B, cleaned address fields in C through F — and write the mailpiece ID or error into column G.
Clean, validate, and send in one shot
Check each row in this sheet for missing values in columns A through F, flag rows with blanks in column H, trim whitespace from address fields, then send a Stannp postcard using template 48291 to all rows where column H is empty and write the mailpiece ID or error into column G.
The pattern: clean the data and trigger the send in a single instruction so the two steps do not drift out of sync between runs.
