Not exactly. Although Moosend does let you do some of the things a CRM platform does. Most email marketing software has some CRM features. They let you manage and segment contact lists. This is important for sending targeted campaigns.
Moosend goes a step further. It lets you track what your contacts get up to on your website and use this data in marketing campaigns. You can even use this information to score your leads, something CRM and marketing automation platforms do.
Moosend only focuses on email interactions, though. A ‘full’ CRM tracks customers across all communication channels.
