While most people realize they can send text messages via a carrier's email gateway, most don't realize that they can send multimedia messages as well. Many carriers have two separate email domains; one for SMS and one for MMS. Others use the same email domain for both. Sending MMS has several advantages. First, the character-count limits which exist for SMS messages (which vary by carrier) don't exist for mms messages. Second, you can attach pictures or sound files to your email messages (the same way you'd attach them when sending to regular email addresses), and your customers will be able to receive them along with your text message. Note that different carriers have different requirements for pictures, and if a picture doesn't meet the criteria, it won't get displayed. We've found that making your jpg file as small as possible is important (Linux users: convert -quality 2 inputfile outputfile). Also, we've found that 320x240 pixels seems to work well for most carriers.
