Mailchimp is an email marketing platform. Connected to WPOS, it lets the agent add subscribers from your site forms and build campaigns and automations, all from the chat beside your site’s live preview. Category: Marketing Actions available: 262+

​
What you can do

  • Add and manage audiences
  • Create campaigns
  • Set up automations
  • Export audience data

​
Example requests

Once Mailchimp is connected, ask in the Command Center:

​
Before you connect

  • A Mailchimp account with at least one audience. Without one there is nothing to add subscribers to.
  • Admin or Manager role. Viewer and Author roles cannot modify audiences or send campaigns.
  • Your server prefix, the region code in your Mailchimp URL, for example us19.

5

Enter your server prefix

Mailchimp is the one connector that asks for something before sign-in. A Composio page headed “WPOS wants to connect to your Mailchimp” asks for a Server Prefix.This is the region code in your Mailchimp URL. If you log in at us19.admin.mailchimp.com, the prefix is us19. It is also the part after the dash in your API key.
Get this wrong and the connection authorizes against the wrong Mailchimp region, so it completes but returns nothing. Copy it from your browser address bar rather than guessing.

Log in and authorize

Mailchimp shows “Log in and authorize”. Enter your username and password, or continue with Google if that is how the account was created.
If two factor authentication is on, have your authenticator ready. A slow second factor is what usually times the flow out.

Confirm in WPOS

The popup closes on its own. The row reads Connected with a Disconnect button, and a green “Mailchimp connected” banner appears in the chat.

​
Troubleshooting

The server prefix is wrong. Log in to Mailchimp and copy the region code from the address bar, then disconnect and reconnect with the correct value.
Create one in Mailchimp first, under Audience, then Create Audience.
The audience uses double opt-in, so Mailchimp sends a confirmation and waits. This is correct behaviour, not a fault.
Your role lacks permission, or the sending domain is not authenticated in Mailchimp.
