Nudgemail is a newly launched service that lets you forward any email to the future, without ever creating an account. Forward or cc to email@example.com, firstname.lastname@example.org or Monday@nudgemail.com and that's when you'll get a follow-up email back in your inbox.
If you try to get rid of every email that ever hits your inbox, if you are required to archive every email you send and receive for work, or if you're like me and just don't care about hundreds of thousands of unread messages in your inbox - then Nudgemail probably isn't for you. But if you use your email inbox like a To Do list and would like to hit snooze on a thread - then you might like the service quite a bit. The email inbox is a big frontier for software development and this is just the latest example of that.
Toeman says that Nudgemail uses SendGrid for secure handling of email and his service never sees the content of your messages. (Disclosure: SendGrid sponsors ReadWriteWeb.) The service is free today and may offer group licensing packages for companies if it catches on.
Related or competing services include Followup.cc, TaskForceApp and IssueBurner. This is clearly not a brand new type of technology, but different services will serve different people well. There's also the fun old classic Futureme.org.
It's pretty clear that email provides a huge potential for extensibility, given the wide range of ways people use it. The inbox is much more than just a place for incoming mail, it is the primary dashboard for many web users - it is how they manage their lives.
So when looking at email as a platform, the opportunities for making it more useful and productive reach most areas of online activities.
Does Nudgemail sound like a productivity hack, as a service, that could be useful to you?
