Autoresponders are a very important tool to any online businesses. Which autoresponder service do you use, and why? Or do you do it yourself? Start rolling in opinions!
I use the built in with my client...works pretty effectively. There's no need to go out and buy a service or anything for it..it's easy to setup.
Aweber for now...Im however looking forward to getting someone to code me one with all the little things that I need/want
I use my Blackberry to make sure a client's message never goes unanswered. To be honest, I find answering emails every time, even with just a 'I'll get back to you shortly' type of message, encourages me to get on the ball right away to wrap things up. Makes for great support response time
Play it safe, use aweber. To be flexible and adjust to difficult demands you will need a script. Ideally one that is central and handle multiple accounts and auto-saves your database to an off-server location, that's important.
