aweber is top on the list
aweber is a great autoresponder for 20usd per month
trafficwave do a unlimited 30 day trial,plus it was $17 a month after that, unlimited.It does not look as good as aweber but a lot of folks moving across because of price,im not an affiliate but i thought somebody on a budget(like me) might want to check it out.
Cant remember what trial period aweber offer now but i did like the look and feel of aweber, its just whatever you feel is cost effective.
hope that helps
I think trafficwave worth it.
I have the old aweber account $19 for 10.000 subscriber, very worth !
I am using Rapidresponsebot. It's not as advance as Aweber (in terms of Javascript stuff) but it's comparably cheap and there's no limitation of number of subscribers. :-)
just tried ListWire.com
very disappointed! At start it brag about 100% free and all that scrap! Then, after spending hours launching my first campaign.. only to realize that they force 2 UpSell and 1 OTO into your list!! WTF!! Any visitors will be pissed off for been over promoting my opt-in. So yeah, goodbye Listwire! You sucks!
Trying on other autoresponders.
Cheers.
