Aweber vs. Getresponse is a real tough one for me. I use both and they are amazing email marketing softwares. The only thing I can say is you can give both of them a free 30 day trial and If you do not like either one you can cancel.The price for Aweber is a little higher. They want $19 for your first 500 subscribers. With Getresponse, they only charge you $15 for your first 1,000 subscribers. Aweber and Getresponse have very good high deliverability to your inbox without going to your junk or spam folders. With Getresponse they have more features and is a lot more easier to navigate and have better tutorials but that is just me. Also with Getresponse you can load leads into the system and with Aweber you can not. Aweber is great too but it really is on you. Like I said you can give both a free 30 day trial and see for yourself. Just make sure you cancel the services before the 30 days are up so you will not be billed. But, If you like them stay with it and learn either service or both services inside and out. And that might take more than 30 days to do that. Some of you might like Aweber better and some of you might like Getresponse. Give one of these or both of these a try because the money is in the list. An autoresponder is very important in affiliate marketing or any business.
