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.
No credit card required.
Why do data teams choose Erathos for Mailchimp?
Ready-to-use MailChimp connector
Connect MailChimp to PostgreSQL in minutes. Lists, campaigns, automations, and events are synchronized automatically—with full engagement tracking and no manual scripts.
Total control over your MailChimp pipelines
Configure sync frequency and type by table. Erathos uses intelligent UPSERT in PostgreSQL—ensuring data consistency even during reprocessing.
End-to-end observability
Stop finding out about Mailchimp failures only after the business team complains. Every run is logged with runtime, processed rows, and error context. Get automatic alerts in Slack, Discord, or email the moment anything drifts from expected behavior—so your marketing data stays fresh for the next campaign analysis.

Bruno Rosso
Data Analyst
Every new source implementation, if I had to do it alone, would take me about two or three months. With Erathos, it's done in a few hours. I don't need a data engineer's skillset to deliver real value with company data.

Luis Ribas
CTO
I can describe my experience with Erathos as seamless; we had no major issues migrating from our old data pipeline platform. Their support is always impeccable, both in answering questions and resolving issues. I highly recommend them, without a doubt.

Sayuri Valente
Project Manager
The robustness and efficiency of Erathos's connectors—whether for Meta, Google, RD Station, or ERPs like Bling and Conta Azul—make the entire pipeline much faster and more reliable. The technical documentation is extremely well-crafted and intuitive, which greatly legacy simplifies implementation.

Kauê Raizer
Co-founder
Centralizing our data with Erathos gave us a roadmap to structure the company: today, we can view NPS and churn in a consolidated way and use that to drive decisions. If I were to give advice to another founder, it would be: centralize your data from day one.

Matheus Nunes
CTO & Co-founder
Erathos revolutionized data management at WE. By integrating multiple SaaS platforms into a single DW, our engineering team can now focus on the core business. We implemented dashboards providing insights across all departments, enriching our data culture and streamlining decision-making.

Fernando R.
Head of Data
Erathos brought an incredible boost in productivity. With no worries about data ingestion, the team focused on strategy rather than pipeline maintenance. Implementing a new connector takes minutes, and the reliability is outstanding. It was one of the best decisions we've made.

Carlos Schwabe
Co-Founder & CDO
We used to have a lot of rework, but not anymore. Working this way is much more efficient. If it's not your core business, hire Erathos. Spend your time modeling your own domain, not someone else's.

Fernando Costa
CTO & Co-founder
It was impossible to run our operations on spreadsheets. Erathos was a perfect fit: they became the data engineer I didn't have. We managed to reduce analysis time, establish weekly data rituals, and, most importantly, trust the data we use.

Thiago Paz
CFO
If I didn't have this infrastructure, I would need three or four people to do what Erathos does today. I was able to drive real value from my data with a much leaner team than I ever imagined needing.

Felipe Corrêa
CTO & Co-founder
Erathos is essential for anyone looking for a quick go-live when centralizing data from multiple sources. We successfully integrated 6 different data sources in a single day, something that would have taken weeks without Erathos.
