No. Outfunnel works with a single Mailchimp/ActiveCampaign and CRM (Pipedrive, Hubspot, or Copper) account.
That said, it is possible to replace the existing account with a new one by navigating to account settings and clicking on “Reconnect”.
PS. Before reconnecting, make sure you are logged in with the new Mailchimp/ActiveCampaign, Pipedrive, Hubspot, or Copper account you want to connect.
