Automatic newsletters from new posts from specific users

Right now, i use Sendy to create and send newsletters (not the default ipb newsletters section in the admin)

There is a zap that creates automatically newsletter drafts from new posts in wordpress

I need a similar functionality for invision board:
Automatically create newsletters that contain X number of posts from a specific user.

The posts in the created newsletter should contain:
- the title of the topic
- a number X of characters form the topic as a short description
- the first image from the topic larger than x px wide. should be set as main image of the newsletter item

Here's an example of newsletter

P.S: Although it would be great to have invision board integrated with sendy in a similar way wordpress is, i do not mind if a plugin in invision board would create newsletter campains using the default newsletters section in the admin

Anyone interested?
