Mailchimp is an extensive email marketing tool, and probably the most versatile out there! Targeted campaigns, newsletters, and automated messages together with a broad range of excellent and customizable templates and pre-made campaigns will make this a breeze!
HubSpot CRM arms your sales team with the information and the tools needed for today's modern sales process. HubSpot Marketing, meanwhile, is the marketer's number one inbound marketing tool that can help with landing page creation, email campaigns, social media scheduling and blogging. PieSync supports both Hubspot CRM as well as Hubspot Marketing.
PieSync integrates Mailchimp with other apps for an automatic 2-way subscribers sync. Every time a subscriber is added in Mailchimp, or it gets updated, it is automatically synced with the other app, and vice versa - eliminating import/export!
Typically, CRM's only support one-way, manual pushes of contacts into Mailchimp lists. In contrast, PieSync syncs in real time, all the time, and it goes 2-way, supporting tags & groups!
