MailChimp + PostgreSQL
Mailchimp is an email marketing platform that provides an effective way to automate and streamline email campaigns, including newsletter creation, audience segmentation, A/B testing, and performance reporting. PostgreSQL, on the other hand, is a robust, scalable open-source relational database management system. It supports a wide range of data types and advanced capabilities.
With Erathos, you can connect Mailchimp data to PostgreSQL in just a few minutes. Our platform handles the entire data movement process into your analytics stack and lets you combine that data with other sources in your Data Warehouse. That way, your time goes toward what really drives value — extracting actionable insights and making more data-driven decisions.

What Mailchimp data does Erathos sync with PostgreSQL?
The integration automatically syncs the main Mailchimp objects:
- Contact lists — segments, tags, and inclusion criteria
- Campaigns — status, send metrics, and campaign performance
- Automations — workflows, steps, and outcomes for each automation
- Engagement events — opens, clicks, conversions, and unsubscribes
- Email metrics — open rate, CTR, bounce rate, and deliverability
- Custom fields — custom properties and tags
Why sync Mailchimp with PostgreSQL?
Mailchimp's built-in analytics show campaign performance in isolation. In PostgreSQL, you can blend that data with revenue, product usage, and support — calculating the true ROI of each campaign, identifying which automations drive higher-LTV customers, and uncovering the channels that convert best for retention, not just acquisition.
How it works
Erathos connects to Mailchimp via the official API and syncs your data incrementally — only new or updated records are processed on each run, keeping pipelines fast and PostgreSQL costs predictable. You choose the sync frequency (from every 5 minutes to daily), the objects to sync, and the destination dataset. Every run is fully observable: execution time, rows processed, context-rich errors, and instant alerts via Slack or email if anything goes wrong.
Centralizing MailChimp data in PostgreSQL has never been so simple
Erathos is a data ingestion platform for teams that need to centralize marketing data reliably. With the MailChimp connector, you can automatically move lists, campaigns, automations, and engagement events into PostgreSQL—with full logs, smart alerts, and zero maintenance.

“Every new source implementation, if I had to do it myself, would take about two or three months. With Erathos, it's done in a few hours. I don't need the skills of a data engineer to generate real value from the company's data.”
“Erathos revolutionized data management at WE. By integrating multiple SaaS tools into a single DW, our technical team now focuses on the core business. We implemented dashboards with insights across every area, enriching our organizational culture and improving our decision-making.”
“We used to have a lot of rework, and now we don't. It's more efficient to work this way. If it's not your core business, hire Erathos. Spend your time modeling your own domain, not someone else's.”
“If I didn't have this infrastructure, I'd need three or four people to do what Erathos does today. I was able to generate real value from my data with a much leaner setup than I thought I'd need. That's the core of building a data-driven culture: the team only uses data when they can trust it.”
“Erathos brought a practical turnaround at CCM. We were able to integrate financial systems, CRM, and processes with BigQuery in just a few clicks, with no technical team required. That gave us a reliable data warehouse that powers automations, dashboards, and even our customer service bots.”
“The robustness and efficiency of Erathos's connectors — whether for Meta, Google, RD Station, or ERPs like Bling and Conta Azul — make the whole process much faster and more reliable. The technical documentation is extremely well put together and intuitive, which makes implementation much easier.”
