Connect
Mailchimp
Mailchimp connects through OAuth 2.0. You authorize Modiva from Mailchimp's own login and consent screen — Modiva then manages your audiences and members, creates, sends and schedules campaigns, and reads performance reports through one unified API and MCP server. Mailchimp access tokens don't expire, so once connected your account stays connected until you revoke it.
Before you start
- A Mailchimp account (any plan, including Free).
- Access to the Mailchimp account you want to connect.
Step-by-step setup
- 1
Sign in to Modiva
Log in at modiva.ai and open the Dashboard. You need a Modiva account before you can connect any platform — creating one takes a minute and no credit card is required for the free tier.
The Modiva dashboard — your home for connections, posts and analytics. - 2
Open Connections → New connection
In the left sidebar choose Connections, then click New connection. You'll see the full catalogue of platforms grouped by category (Social, Ads and CRM).
The connection picker. Use the search box or category filter to find your platform. - 3
Select Mailchimp
Click the Mailchimp card. Modiva redirects you to Mailchimp's official sign-in and permission screen — your password is entered on Mailchimp, never on Modiva.
Click Connect on the Mailchimp card to start the secure OAuth flow. - 4
Authorize Modiva on Mailchimp
Review the permissions Modiva is requesting and approve them. If you manage more than one account, page or profile, pick the one you want Modiva to manage.
Mailchimp's consent screen. Approve the requested scopes to continue. - 5
You're connected
Mailchimp now sends you back to Modiva and the connection appears with a green Connected status. From here it's available to every MCP key and API call in your workspace.
A healthy connection shows a green dot and the connected account name.
Permissions Modiva requests
When you connect Mailchimp, Modiva asks only for the access it needs to run the tools you use. You can revoke it any time from Mailchimp or by disconnecting in Modiva.
- Read and write audiences (lists) and their members
- Add and update member tags
- Create, send and schedule campaigns
- Read campaign performance reports
Troubleshooting & FAQ
Where is my Mailchimp password stored?
Nowhere. You sign in on the provider's own site and Modiva only receives a scoped access token, which is encrypted at rest with AES-256-GCM. Modiva never sees your password.
My connection says Expired or Error — what do I do?
Open Connections, find the platform and click Reconnect (or Refresh token). Providers periodically expire tokens or revoke them when you change your password; reconnecting re-runs the consent screen and restores access.
How do I disconnect?
Open Connections, click the Mailchimp row and choose Disconnect. Modiva deletes the stored token immediately. You can also revoke Modiva from inside Mailchimp's own app settings.
Which Mailchimp account gets connected?
The account you sign into when you approve the consent screen. Mailchimp OAuth grants access to a single account; to connect another, sign into it before authorizing or add a second connection.
Do I need a paid Mailchimp plan?
No. Managing audiences and members and creating campaigns works on Mailchimp's Free plan. Some sending volumes and advanced features depend on your plan, but connecting and using the core tools does not.
Do Mailchimp tokens expire?
No. Mailchimp issues a long-lived token and Modiva discovers your account's data center automatically, so there's no background refresh — the connection stays healthy until you disconnect.
