The Scenario
You are a deliverability consultant. A client's MailerLite open rates dropped 8 percentage points in six weeks. Your working hypothesis is a list hygiene problem — hard bounces accumulating, unsubscribes clustering after specific campaigns.
To test this you need every hard-bounce and unsubscribe event from the past 30 days in an Excel workbook. The client's account has ~14,000 active subscribers.
The bad version:
- You log into the client's MailerLite dashboard
- You navigate to Subscribers, filter by status: Bounced, export CSV — 340 rows
- You do the same for Unsubscribed — 210 rows
- You open both CSVs in Excel, merge them, add a Type column to distinguish them
- You realize the bounce export does not include bounce reason
- You go back to the MailerLite docs to find where bounce reason lives
- It is 4 PM and you have not started the analysis.
The fast version is one prompt and you start the analysis before lunch.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Excel workbook that calls the MailerLite API for exactly the data you need and writes it in the shape you specify.
Open the SheetXAI sidebar and type:
Fetch all MailerLite subscribers with status 'bounced' or 'unsubscribed' that changed status in the past 30 days. Write email, status, bounce reason (if applicable), and date of status change into this workbook — one row per subscriber, newest first.
SheetXAI calls the MailerLite API, retrieves the records, and writes them into the workbook. No CSV merging, no separate exports.
What You Get
A workbook ready for deliverability analysis:
- Email address for every bounced or unsubscribed subscriber
- Status type in a separate column
- Bounce reason — where available from the API
- Date of status change — so you can correlate spikes with specific sends
The date column is what makes the analysis possible. If 80 unsubscribes hit on the same day as a specific campaign, that is your signal.
What If the Data Is Not Quite Ready
Deliverability audits often need more than a status list. SheetXAI layers in additional context in the same prompt.
When you need per-subscriber activity history
You want the sequence of events for the worst offenders — which campaigns they opened before bouncing.
Pull the activity log for each subscriber in column A with status 'bounced' and list every event type, campaign name, and event timestamp in this workbook — one event per row. Add a column for subscriber email so you can group by subscriber.
When you want bounces correlated to specific campaigns
The working hypothesis is that one badly targeted campaign drove the bounce spike.
Fetch all hard-bounce events from the past 30 days in MailerLite. Write subscriber email, bounce date, and the campaign name that triggered the bounce into this workbook. Then add a summary section showing total bounces per campaign, sorted descending.
When you only want hard bounces, not soft bounces
Soft bounces are noise for a list hygiene audit.
Fetch all MailerLite subscribers with status 'bounced' and bounce type 'hard' that changed status in the past 30 days. Write email, bounce reason, and date into this workbook.
When you want a full hygiene report in one view
The client wants one document showing the full picture of list decay for their leadership.
Fetch all MailerLite subscribers with status 'bounced', 'unsubscribed', or 'junk' that changed status in the past 60 days. Write email, status, bounce reason (if applicable), and date into this workbook. Then add a summary row at the top broken down by status type with counts and the date range each covers.
The pattern: describe the shape of the audit. SheetXAI fetches, formats, and summarizes in the same prompt.
Try It
Get the 7-day free trial of SheetXAI and open a blank Excel workbook, then ask it to pull your MailerLite bounce and unsubscribe records for the date range you need. The MailerLite integration is included in every SheetXAI plan. For related workflows, see how to pull an account health snapshot into Excel or the MailerLite in Excel overview.
