How to Connect MailerSend to Excel (4 Methods Compared)

The Problem With Getting Workbook Data In and Out of MailerSend

You have an Excel workbook full of data — recipient lists, suppression records, bounce reports, API token inventories. You need it pushed into MailerSend, or you need MailerSend's data pulled back into the workbook, without rebuilding the connection by hand every time someone asks.

MailerSend is good at delivering transactional email at volume with clean delivery event tracking. But moving that data into a workbook is a step MailerSend was not built to take for you. The usual flow is exporting a CSV from the dashboard, opening it in Excel, cleaning up the columns that came in formatted wrong, and realizing the field names shifted again from last month's export.

Below are the four common ways teams handle this. Only the last one scales.

Method 1: CSV Export and Paste

The default for Excel users is to export a CSV from MailerSend's dashboard, open it in Excel, and massage the columns into the shape your workbook expects. That involves fixing date formats, normalizing status values, splitting fields that came in concatenated, and manually merging the result into the right worksheet.

That flow is manageable once.

When the same request comes in next week — or when it is a different dataset this time, like the webhook inventory instead of the bounce log — you are running the entire sequence again. MailerSend has a lot of surfaces: message logs, domain records, recipient statuses, template libraries, SMTP credentials. Each one is a separate export, and each export lands differently in Excel depending on regional settings and CSV encoding. The cleanup does not get faster the second time.

Method 2: Power Automate

Power Automate has a MailerSend connector that can trigger on delivery events and write data to an Excel worksheet stored in OneDrive or SharePoint.

Before you go further — do you know what a connector action is? An HTTP trigger? A JSON schema mapping? If those terms do not land clearly, this is not your path. Jump ahead to Method 3 or 4 and save yourself an afternoon of trial and error.

If you are still here, Power Automate can handle this. You set the trigger, authenticate MailerSend, pick the action, map the fields to your worksheet columns, and test the flow. It works.

The constraint is that it is still event-per-row logic.

If you need the last 90 days of message logs, Power Automate cannot go back and retrieve them in bulk from history — it captures events as they happen. You probably just need the bounce data that already exists in your account. You probably have no idea how to set up a scheduled flow that paginates through the MailerSend messages endpoint — and that is a reasonable place to be. So you hand it to whoever manages your Power Platform automations, and now you are waiting.

And once you need to join the bounce log against a suppression list in a different worksheet, you are past what a simple flow can do.

Method 3: The Previous Generation — Connector Add-Ons

Until recently, the best option for repeatable workbook-to-MailerSend workflows was a category of add-ons that let you manually configure column mappings and saved templates. You picked your range, you tagged your fields, you saved a config, you ran it.

That was a meaningful step forward. Output was consistent, configs were reusable, the team did not need to redo formatting on every run.

But the thinking still sat with you. Field mapping, schedule configuration, conditional inclusion logic, column renaming — all of it was manual setup you owned. The tool got the data through, but the moment MailerSend updated a field name in their API response, your config broke until someone went back in and fixed it.

This is the previous generation. It worked, and it asked a lot of the person running it.

The Easy Way: Using SheetXAI in Excel

There is a different way entirely. SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook, understands what you are looking at, and through its built-in MailerSend integration it can push to or pull from MailerSend for you. No CSV exports, no automation scaffolding, no field-mapping templates. You just ask.

Example 1: Pull the full bounce log for delivery analysis

Get all MailerSend messages with status bounced and list them in this worksheet with recipient email, sending domain, and the error reason in columns A through C

SheetXAI queries the MailerSend message log, filters by bounce status, and writes each record into the worksheet with the fields in the columns you named. Rows with missing error reasons get flagged rather than silently dropped.

Example 2: Flag domains with incomplete verification records

Pull every MailerSend sending domain into this worksheet with DKIM, SPF, and MX status in columns B through D, then write YES in column E for any domain where any record is not verified

The pattern: instead of pulling the domain list first and then adding a formula layer to spot gaps, you ask for both the pull and the flagging in one prompt. SheetXAI handles the conditional logic inline.

Try It

Get the 7-day free trial of SheetXAI and open any Excel workbook where you work with MailerSend data — a bounce tracker, a domain audit sheet, a recipient hygiene log — then ask it to do one of the tasks above. The MailerSend integration is included in every SheetXAI plan.
