Why Connect Mailchimp to SimPRO?

Guest booking data in Mailchimp and operations scheduling in SimPRO require manual coordination

Manually copying data between Mailchimp and SimPRO 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 SimPRO requires painful manual exports and spreadsheet merges

Online orders in Mailchimp and in-store inventory in SimPRO are never in sync, frustrating customers

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

New team members take longer to onboard because they must learn manual workarounds to keep Mailchimp and SimPRO aligned
