The Scenario
You are a real estate agent. Spring listing season starts this weekend. You have 500 homeowners in a Google Sheet, one per row, with columns for first name, last name, street address, city, state, and ZIP. You want a personalized postcard in every one of those mailboxes before Friday.
The bad version of this week:
- You log into the PostGrid dashboard and try to find where to upload a recipient list
- You discover PostGrid takes API calls, not CSV uploads from the dashboard
- You ask your developer to write a script for you
- They say they can get to it after the sprint
- The weekend starts and nothing has been mailed.
The fast version is one prompt and 500 postcards queue up while you go show a house.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your spreadsheet that reads the recipient rows and calls PostGrid for you, so you never have to touch the API or wait for a developer.
Open the SheetXAI sidebar and type:
Create a PostGrid postcard for each row in this sheet. Use the first name in column A and last name in column B as the recipient name, address line in column C, city in column D, state in column E, ZIP in column F. Use template ID tmpl_abc123 for the front design. Write the returned postcard ID back into column G for each row.
SheetXAI iterates through all 500 rows, calls PostGrid's postcard endpoint once per row, and writes each returned postcard ID back to column G. By the time you finish your next call, the queue is building.
What You Get
500 PostGrid postcard orders, one per row:
- Recipient — name pulled from columns A and B, address from columns C through F
- Template — the spring-listing design you already configured in PostGrid
- Postcard ID — written back to column G so you have a record of every order
- Personalization — each postcard says this homeowner's name, not a generic "Dear Homeowner"
The IDs in column G are your audit trail. If a homeowner calls and says they did not get the card, you look up their row, take the ID from column G, and pull the delivery status directly in PostGrid. You know exactly what happened and when.
Want to vary the offer by neighborhood? Add a condition to the prompt: "If column H says 'Luxury,' use template ID tmpl_luxury22 instead." SheetXAI routes each row to the right template.
What If the Data Is Not Quite Ready
Mailing lists from CRMs or open-house sign-in sheets are rarely clean. SheetXAI handles the cleanup and the sends in the same prompt.
When address formats are inconsistent
Some rows have the full street address in one cell, others split it across two. PostGrid needs a clean address line.
Normalize the address data across columns C and D so that column C always has the full street address and column D has the city. Then create a PostGrid postcard for each row using template tmpl_abc123 and write the postcard ID into column G.
When some rows are missing a ZIP
A dozen rows have blank ZIP codes from the open-house sign-in sheet. You do not want undeliverable mail going out.
Before sending, check column F for blank ZIP codes. For rows with a blank ZIP, write 'SKIPPED — missing ZIP' into column G and skip the PostGrid call. For all other rows, create the postcard and write the returned postcard ID into column G.
When you only want homeowners in specific neighborhoods
The sheet has all 500 contacts but this campaign targets only two ZIP codes.
Filter to rows where column F is 90210 or 90211. Create a PostGrid postcard for each filtered row using template tmpl_abc123 and write the returned postcard ID into column G. For the excluded rows, leave column G blank.
When the list needs deduplication and you want neighborhood-specific templates
The sheet has duplicates from a merged list, and you want a different design for each of three target neighborhoods.
Deduplicate rows by the combination of first name, last name, and ZIP code, keeping the first occurrence. Then for each remaining row: if column H says 'Beachfront' use template tmpl_beach01, if it says 'Hillside' use tmpl_hill01, otherwise use tmpl_abc123. Create a PostGrid postcard per row and write the returned postcard ID and the template used into columns G and I.
The pattern: instead of cleaning the sheet first and then building a separate send flow, you ask for both in one prompt. SheetXAI handles the conditional logic inline.
Try It
Get the 7-day free trial of SheetXAI and open any mailing list sheet, then ask it to send a PostGrid postcard campaign. The PostGrid integration is included in every SheetXAI plan. For a related workflow, see how to send a bulk letter campaign from a sheet or the PostGrid in Google Sheets overview.
