My clone of OhLife called https://ahhlife.com has been making over $500 per month for years now. Daily journal, handled by replying to a prompt email. Marketing is all word of mouth and an occasional mention like this one on HN. Server costs are stable, no maintenance or new features needed, and only a few customer service requests per year.
I’m playing with a side project idea that requires sending scheduled emails like this.
Would you be willing to briefly discuss what you use for scheduled emails? My plan so far is to just save email schedules into a DB table with a time stamp they’re due and have a cron job that frequently checks it, but I haven’t gotten a chance to test the scalability and performance of this.
750words is probably my favorite side-hustle success story that's also a journaling tool. They grew dynamically to about 10-15k users, about a year later monetized for $5 a mo. after growing to nearly 70k users. Incredibly simple and the money is sort of unbelievable as well.
