Here is a UX trick that I want to share with you.
Context : I'm publishing special deals on my website that I also share in my community. I wanted to allow anybody to subscribe to the deal listing and receive notifications without the feeling of "joining a community". It doesn't make sense for these users to join a community since they just want to receive a notification when a new deal is published. They are passive in the first place.
On my side, I want to grow my community faster and avoid spending time and money in an email marketing / newsletter platform. Centralizing my subscribers and my communications in PeerBoard is part of the strategy.
So the trick I used is to create a form with Formcake (it's a simple and solid form backend). It pushes data to Zapier which creates a new PeerBoard user.
Result : People can now subscribe to my exclusive deals, directly from the listing and they immediately receive a PeerBoard digest that contains some deals and other posts. Since they already step in my community, I hope that they will become active users later on.
