PostSheet got its first paying customer today: An Italian agency that is using it to send marketing emails.
There are people and companies that are using it for other kinds of stuff (like contacting job candidates, asking for internship opportunities, sending product updates, etc.) but they are still using the free tier and have yet to convert to any paid plans.
What's next? I have two big features in mind which will allow me to add some interesting and useful integrations but before that, I'm gonna improve the home page, add a tutorial video, and feature some use-cases.
