Most reminder apps want you to create an account, download an app, enable notifications, and manage yet another inbox. That's a lot of overhead for "remind me to cancel Netflix on Friday." FutureMail does one thing: sends you an email on the date you pick. No account, no app, no notifications to manage. Use it for anything — cancel free trials before you get charged, pay rent on time, renew your passport, remember birthdays. Completely free. No spam or ads in email, ever!
