There are already some ways to achieve this using third-party services or using free SMS gateway by setting up email forwarding. But they do have restrictions and limitations. E.g.: Country based limitations. Sometimes they don’t work at all. Of course privacy is another important concern. I am sure many of us are in need of this SMS alert feature, number of queries raised in various Google forums are a proof for this. So, let’s create our own email notifier service with Google Docs.

Below trick is pretty simple it just takes at the max of 5 minutes to setup. It only uses services provided by Google, no third-party services are involved. Importantly it works in almost all countries, free of cost.

How does it work?

2. Google Docs periodically monitors the label thread for new incoming emails and creates a Google Calendar SMS reminder on receiving it.

3. Google Calendar sends you a SMS alert containing the subject of your message.

So lets see how to set it up. Might look lengthy but it’s very easy.
