- Best if your reporting already lives in a spreadsheet or dashboard
- No data warehouse or engineer needed
- The fastest, cheapest place to start
In our 12: Coupler.io, Supermetrics, Windsor.ai
Type 2
Marketing data hubs & ETL
Collect data from many sources, clean and standardize it, then send it to a warehouse or BI tool.
- Best when data from different platforms won't line up
- Handles bigger, multi-channel setups
- More setup and more cost than spreadsheet tools
Type 3
Reverse ETL & automation
Push data back out of your warehouse into the tools your team uses, or automate app-to-app workflows.
- Best when the data exists but isn't where people work
- Useful for activating audiences and syncing CRMs
- Assumes you already have a warehouse or a clear workflow
Quick rule of thumb
- Need data in sheets and dashboards? start with type 1
- Juggling many platforms that don't agree? type 2
- Data's already centralized, just stuck? type 3

How we review marketing data connectors
We test each connector on the same things: how many sources and destinations it really supports, how easy it is to set up without code, how reliably the data refreshes, and what it costs as you grow. We rank tools on fit, not popularity — the "best" connector depends on your stack, so our picks call out who each one is for.
We don't run pay-to-play rankings. Where pricing or features are listed, we aim to keep them current, but vendors change them often, so always confirm the details on the vendor's own site before you buy. Reviews are dated so you can see how fresh they are.
Marketing data connectors: FAQ
Do I need a data warehouse to use a connector?
No. Spreadsheet and dashboard connectors (like Coupler.io or Supermetrics) send data straight to Google Sheets or Looker Studio — no warehouse required. You only need one once your data outgrows spreadsheets.
Are there free marketing data connectors?
Some. Airbyte is free to self-host, and several tools (Coupler.io, Zapier, Hightouch) offer free plans with limits. Most paid plans scale with how much data you move and how often.
What's the difference between ETL and reverse ETL?
ETL moves data from your platforms into a warehouse or report. Reverse ETL does the opposite — it pushes cleaned data out of the warehouse and back into the tools your team works in, like a CRM.
How often does the data refresh?
Most connectors let you schedule refreshes — hourly, daily, or weekly. Higher refresh rates usually cost more, so match the schedule to how often you actually act on the numbers.
Can I connect any platform to any destination?
Almost, but not quite. Coverage varies by tool, which is why the source and destination lists matter most when choosing. If a specific pairing is critical, confirm it on the vendor's site before committing.
