The Scenario
You're running a re-engagement initiative. The theory is simple: some portion of the 500 email addresses in your 'Customer List' sheet have never actually been reached by a campaign — they signed up, got added to a list, and then something broke in the delivery chain. Before you write off these contacts as disengaged, you want to know which ones have zero campaign deliveries in Doppler.
Your manager asked for the segment last Friday. It's now Monday morning.
The bad version:
- Open Doppler, navigate to subscriber management, search for the first email address in your sheet, click into the subscriber record, note the delivery count in a cell, go back, search the next one.
- After ten minutes you've checked eight contacts. You have 492 to go.
- Realize you can't bulk-query delivery history from the Doppler UI. The only way to do this at scale is through the API, which you don't know how to call.
The segment isn't going to materialize from manual clicking. The work is going to fall to someone who can write an API script, which means waiting in line behind three other requests.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Google Sheet. It reads your data and through its built-in Doppler integration it can look up each subscriber's delivery history from the API and write the results back into your sheet — row by row, without you writing a line of code.
For each email in column A of the 'Customer List' sheet, retrieve the Doppler subscriber delivery history and write the total campaigns delivered and date of last delivery into columns B and C.
What You Get
- Column B populated with the total number of campaigns delivered to each subscriber.
- Column C populated with the date of the most recent delivery.
- Rows where Doppler returns zero deliveries left with a 0 in column B and 'Never reached' in column C so the segment is immediately identifiable.
- Any emails not found in Doppler flagged with 'Not in Doppler' in column B rather than left blank.
What If the Data Is Not Quite Ready
You want a simple Active / Never Reached label instead of raw delivery counts
Read the 'Segment Candidates' sheet (column A = email), fetch each subscriber's delivery count from Doppler, and populate column B with 'Active' if deliveries > 0 and 'Never Reached' if 0.
Some email addresses in the sheet have extra spaces or inconsistent casing that might cause lookup failures
Read column A of the 'Customer List' sheet, trim whitespace and lowercase each email before querying Doppler, then write the delivery count into column B and the last delivery date into column C. Flag any lookups that returned no match in column D.
You want to cross-reference delivery history against a second tab that has unsubscribe dates
For each email in column A of the 'Customer List' sheet, fetch the Doppler delivery count and write it into column B. Then check if the same email appears in the 'Unsubscribes' tab — if yes, write the unsubscribe date into column C and 'Churned' into column D.
Full enrichment, segmentation, and priority scoring in one pass
Read the 'Customer List' sheet (column A = email), fetch delivery count and last delivery date from Doppler for each, write them into columns B and C, then add column D with 'High Priority' if deliveries = 0, 'Re-engage' if deliveries > 0 and last delivery older than 180 days, and 'Active' otherwise. Sort by column D then by delivery count ascending.
Everything your re-engagement team needs to start the campaign — in one prompt, no API scripts, no waiting in line.
Try It
Get the 7-day free trial of SheetXAI and open the Google Sheet with your re-engagement contact list, then ask it to enrich each row with Doppler delivery history. Once you know which contacts were never reached, the bulk import spoke covers pushing a cleaned segment into a new Doppler list.
