The Scenario
You are a growth marketer at a SaaS company. You are mailing 200 trial-expiry letters this week, and you want to know which recipients actually come back. Every letter needs a unique URL so you can track reactivation by individual recipient.
Your mailing list lives in a Google Sheet: recipient name in column A, a unique slug in column B, and company in column C. PostGrid's URL tracker feature can generate a personalized redirect link for each one.
The slow version:
- You manually create a PostGrid tracker for each recipient in the dashboard
- 200 trackers created by hand
- By tracker 40 you are making copy-paste errors
- You lose track of which tracker ID maps to which recipient
- The campaign goes out and you cannot attribute a single reactivation to a specific person.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your mailing list and creates a PostGrid tracker per row, writing the tracker ID back to the sheet so you can embed it in each letter and pull engagement data later.
Open the SheetXAI sidebar and type:
For each row in the 'Mail Merge' sheet, create a PostGrid tracker with a redirect URL of https://app.example.com/reactivate/ followed by the slug from column B. Write the returned tracker ID into column C and the full tracking URL into column D.
SheetXAI creates 200 trackers, one per row, and writes each tracker ID and tracking URL back to the sheet. The letter template can now pull from column D to embed each recipient's unique link.
What You Get
200 PostGrid tracker records, logged back to the sheet:
- Tracker ID — written to column C, one per recipient
- Tracking URL — written to column D, the full redirect URL for that person
- Attribution — when a recipient clicks through, the tracker ID tells you exactly who it was
Column D is what goes into your letter template. You reference column D in the PostGrid letter merge and each physical letter contains a URL unique to that recipient. No generic link, no guesswork about who converted.
After the campaign lands, use the same sheet to pull engagement: "For each tracker ID in column C, fetch the PostGrid tracker and write the total visit count into column E and the most recent visit date into column F."
What If the Data Is Not Quite Ready
Mailing lists from CRM exports or trial systems are rarely slug-ready. SheetXAI handles the prep and the tracker creation in the same prompt.
When slugs need to be generated from names
Column B is empty because the slugs were never created. You want a unique slug derived from the recipient's name.
For each row in the 'Mail Merge' sheet, generate a unique slug from the name in column A by lowercasing and replacing spaces with hyphens, then appending a four-digit row number. Put the slug into column B. Then create a PostGrid tracker per row with redirect URL https://app.example.com/reactivate/ followed by the slug and write the tracker ID into column C.
When some rows are missing company names and should get a different landing page
The campaign has different landing pages for recipients with known company names versus individuals.
For each row in the 'Mail Merge' sheet, create a PostGrid tracker. If column C has a company name, use redirect URL https://app.example.com/reactivate/business/ plus the slug from column B. If column C is blank, use https://app.example.com/reactivate/personal/ plus the slug. Write the tracker ID into column D.
When you need to pull back engagement data after the campaign
Two weeks after the campaign, you want to know which trackers got visits.
For each tracker ID in column C of the 'Campaign Results' tab, fetch the PostGrid tracker and write the total visit count into column E and the date of the most recent visit into column F. Flag any row where column E is greater than 0 with 'Clicked' in column G.
When slugs need deduplication, company-based routing, and tracker creation plus engagement pull in one session
The sheet has duplicate slugs from a botched export, mixed company and individual rows, and you want the trackers created and engagement pulled from last month's run all in one prompt.
Deduplicate the 'Mail Merge' sheet by the slug in column B, keeping the first occurrence. Generate new unique slugs for any rows where column B is still blank. For tracker creation, route by column C as described above. Create all trackers and write tracker IDs into column D. Then for any row where column E has a tracker ID from last month's run, fetch PostGrid engagement and write visit count into column F.
The pattern: tracker creation and engagement reporting live in the same sheet, driven by the same prompt pattern. You do not need a separate analytics tool to see who clicked.
