MailChimp + Supabase

MailChimp is an email marketing platform that offers an effective approach to automate and simplify email campaigns, such as newsletter creation, audience segmentation, A/B testing, and performance reporting.

With Erathos, you can integrate MailChimp data into Supabase in just a few minutes. Our platform handles the entire data movement process to your open-source backend platform powered by PostgreSQL and lets you combine that data with other sources. That way, your time is focused on what really creates value — extracting insights and making data-driven decisions.

What MailChimp data does Erathos sync with Supabase?

The integration automatically syncs the main MailChimp objects:

Campaigns — name, status, channel, start and end dates
Leads and contacts — source, stage, and engagement data
Performance metrics — impressions, clicks, conversions, and cost per result
Lists and segments — composition and segmentation criteria
Automations — flows, triggers, and conversion rates
Users — profiles, preferences, and interaction history

Why sync MailChimp with Supabase?

In Supabase, your data is available through auto-generated REST and GraphQL APIs based on the schema — accessible directly from your application without extra layers. Row Level Security ensures each user sees only the data they’re supposed to see. Ideal for product teams that want analytical data available in the application database in real time.

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. You choose the sync frequency (from every 5 minutes to daily), which objects to sync, and the destination in Supabase. The sync uses smart UPSERTs in Supabase (PostgreSQL) to ensure data consistency. You choose the sync frequency, the objects to sync, and the target schema. Each run is logged with full observability: execution time, rows processed, and alerts via Slack or email.

Writing data-driven stories

Gustavo Loforte
Engineering Manager
Erathos was a total game-changer for CCM. We managed to integrate our financial systems, CRM, and internal processes with BigQuery in just a few clicks, without needing a data engineering team. This gave us a reliable data warehouse that powers our automations, dashboards, and even our customer service bots.
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.
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.
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.
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.

FAQ

Frequently Asked Questions

What is Erathos, and how can it help my business?

Erathos is a data ingestion platform built for reliability, transparency, and control. We help data teams connect tools like MailChimp to their data warehouse—with full observability into every run, zero maintenance, and none of the black-box behavior of traditional tools on the market.

Which MailChimp data does Erathos sync to Supabase?

The integration between Erathos and MailChimp lets you export campaign metrics, audience data, conversions, cost per click, impressions, and channel performance data. All of it incrementally and without code.

How often does Erathos sync data from MailChimp to Supabase?

You can set the sync frequency anywhere from every 5 minutes to once a day, at the table level. Erathos uses incremental sync—only new or updated records are processed on each run, keeping the MailChimp pipeline efficient and Supabase costs predictable.

What happens if a MailChimp sync fails?

Erathos automatically detects failures and sends alerts to your email, Slack, or Discord with full context — not just “job failed.” Smart retries handle transient errors, and every run is logged with runtime, rows processed, and error context so your team can debug in minutes, not hours.
