The Scenario
You are a retention marketer at a SaaS company. You are mailing 200 trial-expiry letters this week and you need to know which recipients actually come back. Every letter gets a unique landing-page URL per recipient so you can track reactivation individually.
Your mailing list lives in an Excel workbook on the Mail Merge tab: recipient name in column A, a unique slug in column B, and company name in column C. PostGrid's URL tracker feature generates personalized redirect links that log visits back to PostGrid.
The slow version:
- You manually create a PostGrid tracker for each of 200 recipients in the dashboard
- By tracker 50 you have made three copy-paste errors
- You have no clean mapping between the tracker IDs and the workbook rows
- The letters go 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 Mail Merge tab and creates a PostGrid tracker per row, writing the tracker ID and tracking URL back to the workbook so each letter can embed a personalized link.
Open the SheetXAI sidebar and type:
For each row in the 'Mail Merge' tab of this workbook, 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 URL back to the workbook. The letter template pulls from column D to embed a unique link per recipient.
What You Get
200 PostGrid tracker records, logged back to the workbook:
- Tracker ID — written to column C, one per recipient
- Tracking URL — written to column D, the unique redirect URL for each 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 conversions.
After the campaign lands, pull engagement data back with: "For each tracker ID in column C of the 'Campaign Results' tab, fetch the PostGrid tracker and write total visit count into column E and the date of the most recent visit into column F."
What If the Data Is Not Quite Ready
Mailing lists from trial systems or CRM exports are rarely slug-ready. SheetXAI handles the prep and the tracker creation in the same prompt.
When slugs need to be generated because column B is empty
The slugs were never created for this batch. You want unique slugs derived from recipient names.
For each row in the 'Mail Merge' tab where column B is blank, generate a unique slug from the name in column A by lowercasing and replacing spaces with hyphens, then appending the row number. Put the slug into column B. Then create a PostGrid tracker per row with redirect URL https://app.example.com/reactivate/ plus the slug, and write the tracker ID into column C and full URL into column D.
When landing pages differ between business and individual recipients
Rows with a company name in column C should go to a business landing page, rows without should go to a personal one.
For each row in the 'Mail Merge' tab, 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 and the full tracking URL into column E.
When you need to pull back engagement data after the campaign has run
Two weeks after sending, you want to know which trackers received visits and flag them for follow-up.
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. For any row where column E is greater than 0, write 'Clicked' into column G.
When slugs need generation, company-based routing, tracker creation, and engagement reporting all happen in one workbook session
The batch has some blank slugs, a mix of business and individual recipients, and the previous month's tracker IDs in a separate tab that need engagement data pulled.
For rows in the 'Mail Merge' tab where column B is blank, generate unique slugs from column A names. For tracker creation, route by column C: business URL for rows with a company name, personal URL for blank. Create all trackers and write IDs into column C and URLs into column D. Then for each tracker ID in column A of the 'October Results' tab, fetch PostGrid engagement and write visit count into column B and last visit date into column C of that tab.
The pattern: slug generation, routing, tracker creation, and engagement pull all live in the same workbook, driven by the same prompt pattern. You do not need a separate analytics tool.
