Text Magic is super simple and easy to use. I haven't needed to consult any help docs, not once. It works well, and creating SMS campaigns are a breeze!

Favourite feature is being able to reply to individual replies from within the platform.

I also love the PAYG (Pay As You Go) feature, so you're not locked into a monthly subscription if you're not using it all the time, like myself. I've used TextMagic many a times for clients.
