The Scenario
You're running a re-engagement initiative. The theory is simple: some portion of the 500 email addresses in your 'Segment Candidates' Excel tab 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 Monday morning.
The bad version:
- Open Doppler, navigate to subscriber management, search for the first email address in your workbook, click into the subscriber record, note the delivery count, 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 path at scale is through the API, which means waiting for whoever on your team can write the script.
The segment isn't going to materialize from manual clicking. You're waiting in a queue.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. 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 workbook — row by row, without you writing a line of code.
Read the 'Segment Candidates' Excel tab (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.
What You Get
- Column B populated for all 500 rows: 'Active' or 'Never Reached' based on Doppler delivery history.
- Any emails not found in Doppler flagged with 'Not in Doppler' in column B rather than left blank.
- The segment ready for filtering immediately — no pivot, no formula cleanup.
- Completed in one pass, not one-by-one manual lookups.
What If the Data Is Not Quite Ready
You want raw delivery counts and last delivery date instead of Active/Never Reached labels
For each email in column A of the 'Segment Candidates' Excel tab, retrieve the Doppler subscriber delivery history and write the total campaigns delivered and date of last delivery into columns B and C.
Some emails have trailing spaces that might cause lookup failures
Read column A of the 'Segment Candidates' Excel tab, 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 'Segment Candidates' Excel tab, fetch the Doppler delivery count and write it into column B. Then check if the same email appears in the 'Unsubscribes' worksheet — 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 'Segment Candidates' Excel tab (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.
Try It
Get the 7-day free trial of SheetXAI and open the Excel workbook 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.
