If you think sending text messaged via your cell phone costs a lot and you desperately need a cheaper way to send group texts then try SendGM. The startup lets you send messages via an email client or browser and is very effective where a group of people often interacts. It also lets you do a bunch of other things as well which include importing contacts or inviting members and adding them to existing groups. The best part is perhaps the recipient acknowledgement option which lets you know who has received the email or not plus letting you create instant polls so that you can take quick decisions with your friends over a plan. Well sounds worth the use, given that it isn’t charging you anything for it.
