Hi, this is Jack! I work with an amazing team here in London to make uMail a super simple yet powerful tool for people like yourself.
The idea of uMail is to very simple: rather than leaving your email address in the public (on your website, twitter page, business card...), you instead leave a short uMail link which redirects people to a page like this. And when people do get in touch, you get their message as an email.
Probably worth mentioning it takes seconds to create a uMail.link like this one!
