# BigMailer

BigMailer is an email marketing platform built for agencies and businesses managing multiple brands. It lets you run bulk campaigns, transactional emails, and list management all from one place. Connecting BigMailer to Coupler.io lets you pull your email data into spreadsheets, dashboards, or AI tools for deeper analysis.

## Why connect BigMailer to Coupler.io?

* **Centralize your email data** — combine campaign performance, contact lists, and suppression data in one destination
* **Report across brands** — use the Append transformation to stack data from multiple brands into a single table
* **Feed AI tools** — send your campaign and contact data directly to ChatGPT, Claude, Gemini, or other AI destinations for analysis and recommendations
* **Automate reporting** — schedule automatic refreshes so your dashboards always reflect the latest data

## Prerequisites

* A BigMailer account with at least one brand set up
* An API key from your BigMailer account settings
* A destination ready — Google Sheets, Excel, BigQuery, Looker Studio, or an AI tool like ChatGPT or Claude

## Quick start

{% hint style="success" %}
If you manage multiple brands in BigMailer, start with the **Bulk campaigns** entity to get a high-level view of campaign performance, then add **Contacts** or **Lists** as additional sources in the same data flow.
{% endhint %}

## How to connect

**Create a new data flow in Coupler.io.** Log in to Coupler.io, go to the Data flows section, and click **Add data flow**. Search for BigMailer and select it as your source.
