The Scenario
You are an email developer. The quarterly list hygiene review is due Friday. Your team sends transactional email to roughly 12,000 addresses and nobody has pulled a systematic bounce report in three months.
The deliverability numbers have been slipping. The infrastructure lead suspects hard-bounced addresses are still sitting in the production database getting re-queued. You need an Excel workbook tab with every hard bounce from the past 30 days — email, bounce type, reason, and timestamp — so the database team can run a scrub.
The slow version:
- Log into the Postmark dashboard, export the bounce CSV, open it in Excel
- Remove columns you do not need, rename headers to match what the database team expects
- Realize the date range cut off two days early, re-export
- Paste both exports, remove overlap, check for gaps
- Forty minutes of reconciliation before you even start the scrub.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook that calls the Postmark bounce API and writes results directly into the workbook, so you do not have to touch the dashboard or reformat a CSV.
Open the SheetXAI sidebar and type:
Fetch all hard bounces from Postmark for the past 30 days and write bounced email, bounce type, description, and bounced-at timestamp into columns A through D of the 'Bounce Report' tab. Include a header row.
SheetXAI calls the Postmark bounce endpoint, paginates through all results, and writes them into the tab with headers. The database team gets the file they need in the format they asked for.
What You Get
A structured bounce report in the 'Bounce Report' tab:
- Column A — bounced email address
- Column B — bounce type (HardBounce, SoftBounce, SpamComplaint, etc.)
- Column C — Postmark's bounce description
- Column D — timestamp of the bounce event
Every hard bounce from the period, not a sample. SheetXAI handles Postmark's API pagination automatically so you get the full set.
What If the Data Is Not Quite Ready
Bounce data is clean; the work around it is not.
When you need to cross-reference against a contacts tab
The database team wants to know which bounced addresses are currently in the active contacts table.
Fetch all hard bounces from Postmark for the past 30 days and write them into the 'Bounce Report' tab with email, type, and timestamp. Then cross-reference column A against the email column in the 'Active Contacts' tab and write 'ACTIVE' or 'NOT IN CRM' in column E for each bounced address.
When the report needs a summary count by bounce type at the top
The infrastructure lead wants aggregate counts before the detail rows.
Fetch all Postmark bounces for the past 30 days and write the detail rows into the 'Bounce Report' tab starting at row 5. In rows 1 through 3, write a summary table showing each bounce type and its count for the period.
When you only want hard bounces but need them split by month
The compliance team wants April and May in separate tabs.
Fetch all Postmark hard bounces for the past 60 days. Write April bounces into the 'April Bounces' tab (columns A–D with headers) and May bounces into the 'May Bounces' tab in the same format.
When you need the full cleanup pipeline — pull, cross-reference, flag, and sort in one shot
The database team is on a deadline and needs an import-ready file.
Fetch all Postmark hard bounces for the past 30 days. Write email, bounce type, and timestamp into columns A, B, and C of the 'Bounce Report' tab. Cross-reference column A against the 'Active Contacts' tab and write 'REMOVE' in column D for any active address that bounced. Sort so REMOVE rows appear at the top. Add a header row.
The pattern: instead of pulling the data and then doing the cross-reference separately, you ask for both in one prompt.
