Enrich a Contact List in Google Sheets With Enginemailer Subscriber Data

The Scenario

It's the week before quarterly business review. You have a Google Sheet with 800 customer emails — the list that feeds your account health scoring model. Someone needs to fill in the current Enginemailer subscriber status, subcategory tags, and custom field values for each row before the model runs Friday morning.

The last time this happened, the analyst on the team spent half a day looking up subscribers one by one in Enginemailer, copying values into the sheet, and making copy-paste errors that corrupted three rows the model later flagged as anomalies.

That analyst is supposed to be running the model, not populating a spreadsheet.

The bad version:

  • Export the full Enginemailer subscriber list, load it into a second tab, and use VLOOKUP to join status and custom fields back to the 800-row list — except the export's column names don't match anything in the sheet.
  • Rename the export columns, re-run the VLOOKUP, notice that 40 emails in the master list have slight formatting differences that cause the lookup to miss, fix the formatting, re-run again.
  • Realize the export is three days old and doesn't reflect status changes from this week, so some of the enriched values are already stale.

The source of truth is Enginemailer, not a three-day-old export. The enrichment should pull from the live system.

The Easy Way: One Prompt in SheetXAI

SheetXAI is an AI agent inside your Google Sheet. It reads each email in your list, looks up the subscriber live in Enginemailer, and writes the status, tags, and custom fields directly into the sheet.

For each email in column A of my 'Customer List' sheet, look up the subscriber in Enginemailer and write their subscription status and all custom fields into columns B onward.

What You Get

  • Each of the 800 emails looked up live in Enginemailer — no stale export, no VLOOKUP gymnastics.
  • Subscription status written to column B for every row.
  • All custom field values written into subsequent columns, with the field names used as column headers.
  • "Not found" written for any email that doesn't exist in Enginemailer, so you know immediately which rows need follow-up.

What If the Data Is Not Quite Ready

You only want status and subcategory tag, not every custom field

The model only needs two fields and you don't want 15 columns appended to the sheet.

Go through all 800 rows in my 'Customer List' sheet, find each email in Enginemailer, and fill columns C and D with the subscriber's current status and subcategory tag.

Some emails have trailing whitespace or domain casing issues causing lookup misses

Before looking up each email in Enginemailer, trim whitespace and lowercase the domain portion of each address in column A. Then fetch subscription status and all custom fields into columns B onward for each match.

You want to flag any contacts whose subscription status changed since last quarter

There's a "Last Known Status" column in column F. You want to compare the fresh Enginemailer status against it.

For each email in column A, fetch the current Enginemailer subscriber status. Write it to column B. Then compare column B to column F — if the status changed, write 'changed' to column G; if it matches, write 'same'.

Clean emails, fetch all fields, compare status, and surface changed records in one pass

In my 'Customer List' sheet: trim and lowercase the domain of each email in column A. Look up each subscriber in Enginemailer and write subscription status to column B and all custom fields to columns C onward. Compare column B to column F and write 'changed' or 'same' to the last column. Sort rows with 'changed' to the top.

The rows sorted to the top are the ones that need a second look before the model runs Friday.
