Syncing Hiveage and Mailchimp is currently on our roadmap
Hiveage is a fast, simple, easy-to-use online invoicing and billing service designed especially for freelancers and small businesses. Whether its sending invoices, accepting payments or automatically charging clients, Hiveage helps you get your finances out of the way, so you can focus on the important stuff. Hiveage comes with a powerful free plan that lets you send unlimited invoices to unlimited clients.
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!
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!
