sms gateways

I've been asked to quote for a website which will allow users to subscribe for periodic SMS messages. Anybody done this?

I'm wondering which providers give a good bang for the buck?

I was hoping to do the 'confirm your subscription' and 'unsubscribe' stuff via sms too. The alternative is to supply number and email, and authenticate via email. Do they provide a number that subscribers can text, which will then be relayed to an email account which I could somehow parse with a php script or something? Do they supply APIs for php?

I use clickatell too. They are the cheapest I found out there. Costs for Irish sms messages as follows:

1 credit = 4.4 cent (gets cheaper with bulk purchases but this is base cost)

087 - 0.8 of a credit, i.e. 3.5 cents
086 - 0.8 of a credit, i.e. 3.5 cents
085 - 0.8 of a credit, i.e. 3.5 cents
083 - 1 credit, i.e. 4.4 cents

They have loads of ways to integrate using xml, soap, com objects, etc. I use the COM. In terms of validating subscribers, I implemented an email/sms notification system on www.raymondpotterton.com. Upon signup, you receive an email with a link that will confirm your email address and an SMS is sent to your phone with a six digit code (after about 5 seconds). On the next page, you have the opportunity to verify your Phone number by entering the code.

If you need more help, just shout!
