If your team runs email campaigns in Mailchimp while your customer data lives in Odoo, you already know what that gap costs. Someone exports contacts to a CSV, uploads it to Mailchimp, and by the time the campaign goes out, the list is already weeks behind. Campaign results sit in Mailchimp while the customer records they relate to are in Odoo. Getting a complete picture means pulling from both and combining them manually – every time.
There’s a cleaner way. The Zehntech Odoo Mailchimp Connector is a native Odoo module that puts both sides of this inside Odoo. This post walks through what it does, how to set it up, and what your workflow looks like once it’s running.
Why the default Odoo-Mailchimp setup doesn’t work
Odoo has no built-in Mailchimp integration. There’s no native sync, no API connection, no way to manage Mailchimp campaigns from inside Odoo out of the box. What most teams end up doing is exporting a contact list from Odoo as a CSV and uploading it to Mailchimp manually – which works until the contact data changes, which it does constantly.
The bigger problem is that manual exports create stale lists by design. A contact that unsubscribes in Mailchimp doesn’t update in Odoo. A new lead that comes into Odoo doesn’t reach Mailchimp until someone remembers to run the export again. For teams sending weekly or bi-weekly campaigns, the list can be significantly out of date before it’s even used.
Campaign data compounds the problem. Open rates, click rates, and delivery status live entirely in Mailchimp. If you want to know how a campaign performed against a specific customer segment – say, contacts at a particular stage in your Odoo pipeline – you have to pull a report from Mailchimp, pull the segment from Odoo, and reconcile them in a spreadsheet. That’s not a process that scales.
For teams running more than one Mailchimp account (different brands, regions, or business units), it gets worse. Each account is a separate login, a separate dashboard, with no connection back to the Odoo data that should be driving the targeting.
What the Odoo Mailchimp Connector does
The Odoo Mailchimp Connector is a standard Odoo module – not a SaaS connector, not middleware you manage separately. It installs directly into your Odoo instance from the Odoo Apps Store and connects to Mailchimp via API key. After that, your Mailchimp accounts, audience lists, contacts, campaigns, and delivery data are all accessible from inside Odoo.
Here’s what it covers:
| Feature | What it does | Why it matters |
|---|---|---|
| Bidirectional contact sync | Fetch Mailchimp contacts into Odoo; export Odoo contacts to Mailchimp | No CSV files. Lists stay current in both directions. |
| Audience list import | Pull Mailchimp audience lists into Odoo, subscription status applied automatically | Your historical Mailchimp data is accessible without a manual re-import |
| Multi-account management | Connect and manage multiple Mailchimp accounts from one Odoo interface | Agencies and multi-brand teams don’t need separate logins per account |
| Campaign creation and send | Build campaigns in Odoo, push to Mailchimp, send without leaving Odoo | The full campaign workflow stays inside one system |
| Delivery metrics in Odoo | Open rates, click rates, delivery status pull back into Odoo automatically | Campaign results sit next to the customer records they relate to |
| Segment and merge field management | Create and manage Mailchimp segments and merge fields from Odoo | Audience targeting happens in Odoo, not Mailchimp |
How to connect Odoo with Mailchimp – step by step
Step 1: Install the Odoo Mailchimp Connector
Go to the Odoo Apps Store and search for “Mailchimp Connector” by Zehntech. The module is available for Odoo 16, 17, 18, and 19 – pick the version that matches your current Odoo installation. Install it the same way you’d install any other Odoo module. No server restart required.
Step 2: Add your Mailchimp API key
After installation, go to the Mailchimp settings section inside Odoo. Enter your Mailchimp API key (available in your Mailchimp account under Account > Extras > API Keys). The connector validates the key and links your account immediately. If you manage more than one Mailchimp account, repeat this step for each one.
Step 3: Import your Mailchimp audience lists
Use the import function to pull your existing Mailchimp audience lists into Odoo. Member contacts come across with their subscription status already applied and sorted – subscribed, unsubscribed, and cleaned contacts are categorized automatically. No manual CSV export from Mailchimp, no import wizard in Odoo.
Step 4: Sync Odoo contacts to Mailchimp
To push Odoo contacts to Mailchimp, use the export function from your Odoo contact list. When contact details change in Odoo, you can push those updates to Mailchimp to keep the records in sync. This replaces the manual CSV export cycle entirely.
Step 5: Create campaigns, send, and track
Build new campaigns inside Odoo or import existing ones from Mailchimp. Once a campaign is ready, trigger the send directly from Odoo – no Mailchimp login required. Delivery metrics (open rates, click rates, delivery status) pull back into Odoo automatically and appear alongside the campaign record.

What you can manage from Odoo after setup
Once the connector is running, the day-to-day Mailchimp workflow mostly happens inside Odoo. Contacts sync without manual intervention. Campaigns you create in Odoo push to Mailchimp. Metrics come back automatically.
Multiple accounts. If you’re managing campaigns for more than one brand or region, all connected Mailchimp accounts are visible in one place. You can run bulk operations across accounts without switching between them – useful for agencies or businesses with separate Mailchimp environments for different markets.
Segments and merge fields. Audience targeting and field configuration happen inside Odoo. You can create and manage Mailchimp segments and merge fields without opening the Mailchimp interface. This is particularly useful if your segmentation logic is based on Odoo data such as customer type, pipeline stage, or region.
Campaign lifecycle. The full process from list import to campaign creation to send to metrics tracking stays inside Odoo. The only time you’d need to open Mailchimp directly is for template design work the connector doesn’t cover. For everything else – contacts, campaigns, reporting – Odoo handles it.
If you’re also using Odoo for sales analytics and want to tie email campaign performance to pipeline data, it’s worth reading how the Odoo Power BI Connector handles cross-system reporting. That combination covers both campaign execution and business intelligence in one environment.
Is this the right setup for your team?
This connector works well if your team uses Odoo as your primary CRM or ERP and Mailchimp for email campaigns. The value comes from having both systems talk to each other – contacts in Odoo staying current in Mailchimp, campaign results visible next to the customer records they relate to. If that describes your setup, the manual export cycle and split reporting are the exact problems this solves.
It’s not the right fit if your team uses Mailchimp as a completely standalone tool with no dependency on Odoo contact data. If your Mailchimp lists are built and maintained entirely inside Mailchimp and your Odoo instance doesn’t factor into your email targeting at all, the connector adds complexity without a clear benefit.
