Here’s a handy Wikipedia page I came across the other day. It lists a bunch of email to sms gateways that are offered by cell phone companies. Why would you want this? Well, here’s a few handy uses I thought of:

• Have a web app or desktop app that can send reminders via email? Send them via text message so you’ll be reminded while you’re out.
• If you have a contact form on your site, you could send yourself a text message to alert you of a new submission (maybe an important RFP??).
• Send an email when a client’s web app has an error, so you can get a fix put in place before they complain (which is always nice).

There are tons of other ways to use this technology. The best part is that it’s super easy to send an email via backend code like php or via desktop apps like iCal. This makes it easy to turn that email into a text message.
