I m building a pet project for a local community, and I need to send emails - potentially thousands of them. The project won t be commercial, so I d like to spend as little money as possible. I d also like to avoid hosting a custom SMTP server or dealing with all the setup.It seems like there are quite a few email providers on the market, but I m not sure whether my project would meet their requirements.What would you recommend as a cheap and reliable(good deliverability) provider for transactional emails? What email providers do you use for pet projects?
