Why Connect Mailchimp to Teamwork?

Student enrolment data in Mailchimp and billing records in Teamwork are managed separately, causing discrepancies

Manually copying data between Mailchimp and Teamwork wastes hours every week that could be spent on revenue-generating work

No single source of truth when contacts live in two disconnected tools, so staff second-guess which system has the correct information

Reporting across Mailchimp and Teamwork requires painful manual exports and spreadsheet merges

Teamwork adds complexity: reporting depth requires the higher-tier plans, with basic plans offering limited dashboard customisation and export options

Mailchimp limitations compound the integration challenge: the platform tries to be an all-in-one marketing tool, but the website builder, social posting, and CRM features feel bolted on rather than integrated
