MailChimp is an email marketing platform that provides an effective approach to automating and streamlining email campaigns, such as newsletter creation, audience segmentation, A/B testing, and performance reports. Postgres, in turn, is a highly robust and scalable open-source relational database management system. It supports a wide range of data types and advanced features.

With Erathos, MailChimp data lands in BigQuery within minutes, ready to be joined with other business sources in ad hoc queries, without your team needing to manage ingestion infrastructure.

### Which MailChimp data does Erathos sync to PostgreSQL?

The integration automatically syncs key MailChimp objects:

- **Contact lists** segments, tags, and inclusion criteria
- **Campaigns** status, send metrics, and performance per campaign
- **Automations** workflows, steps, and results for each automation
- **Engagement events** opens, clicks, conversions, and unsubscribes
- **Email metrics** open rate, CTR, bounces, and deliverability
- **Custom fields** custom properties and tags

### Why sync MailChimp with BigQuery?

In BigQuery, you can join MailChimp data with other business sources, running ad hoc queries in seconds over massive volumes without managing infrastructure.

### How it works

Erathos connects to MailChimp via its official API and syncs your data incrementally: only new or updated records are processed on each run, keeping pipelines fast and BigQuery costs predictable. You choose the sync frequency (ranging from every 5 minutes to daily), the objects to sync, and the destination dataset. Every run is logged with full observability: run time, rows processed, errors with context, and instant alerts via Slack or email if anything goes wrong.
