Syncing ERPNext and Sendy is currently on our roadmap
ERPNext is a full featured business management solution that helps SMEs to record all the business transactions in one system. Further, SMEs can use it to make informed, fact based, timely decisions & remain ahead of the competition. It serves as the backbone of a business to add strength, transparency and control to your growing enterprise.
Sendy is a self hosted email newsletter application that lets you send trackable emails via Amazon Simple Email Service (SES). This makes it possible for you to send authenticated bulk emails at an insanely low price without sacrificing deliverability.
This 2-way sync for ERPNext works with leads, contacts, as well as customers. Upon setting up a sync, you get to decide what to sync. You can set up multiple concurrent syncs to have various objects syncing 2-way with other apps. Both ERPNext Cloud as self-hosted versions are supported.
