This is a fine line to walk indeed: you don't want to spam the user, but you also want to stay "top of mind" in the prospect mind.

I think most of app founders view this under the lens of "how can we get this user to use our app?" which I think is a wrong approach.

To me the right approach as always is to start from the user, and not to see yourself (the app maker) as just this app provider. Instead, see yourself as a business coach and help the user solving the business problem (that your product solves).

Brennan Dunn's app (planscope.io) does this quite well. He doesn't just tell you to use his app, by he actively tries to educate you on how to win proposals (and his app is project management app).

Your end goals as a business app provider should be to solve for your customer success. By solving for customer success, you will solve for your product long term success. And this should drive every decision in the business.

So when you think about that email that you send, ask yourself "is this contributing to our customer success? or is it just spamming this user who might need something else at this moment?"
