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!
Contacts+ is the most powerful fully-connected contact management platform for professionals and enterprises who need to master their contacts and be awesome with people. Contacts+ cross-platform suite of Apps and APIs enhance contacts with 360-degree insights, while keeping them organized, in-sync, up-to-date, and safe.
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!
