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.
