Email Moblogging

If your mobile phone supports sending email or MMS, email moblogging doesn't have any of the drawbacks of SMS moblogging:

There is no practical length limitation, as long as your thumbs don't complain.
You can post photos from a camera phone, adding richness to your post.
There is no extra charge besides what you pay for the wireless data and regular blog hosting service.

Email moblogging works in much the same way as its SMS counterpart, except that you send email from the phone to a (hopefully) secret email address. The email Inbox is polled by the moblog service at regular intervals (e.g., every five minutes). When a new message is detected, the moblog service retrieves the message and parses the content. If the moblog service supports picture attachments (most do), you can even have a mobile photo blog!

It is important that you keep the email address private. Any message sent to that email address will be automatically posted on your blog.

The easiest way to set up an email-based moblog is to use a blog-hosting service that supports email posting. It typically takes only a few minutes. After you open a regular blog account at the hosting service, there is usually a field under the user preferences screen where you can set the private email address. All emails sent to this address will be posted to the blog you just opened.

Most popular blog-hosting providers now support email posting from mobile phones, either free of charge (e.g., Blogger) or with a premium paid account (e.g., LiveJournal).
Besides the major blog providers, some new providers specialize in moblog hosting. Among them are Textamerica (http://www.textamerica.com) and Fotolog (http://www.fotolog.net). Both of them offer free accounts for users to blog directly from their mobile phones.
The free accounts often come with the condition that the service provider can display advertisements on your blog pages.
