iContact doesn’t force you to reconfirm. it’s the only one i’m aware of that lets you do this. i just am not a fan of their billing system because they charge on subscribers and number of sends. you get 6 “free” sends in your subscriber package per month. then if you want more, you gotta buy a higher subscriber count package.
it’s a bit hard to explain.
but let’s say you have 4,000 people – so you buy the 5,000 subscriber plan. no probs.
as long as you only want to send 6 emails a month (which is lame btw).
if you want to send a daily message (so 30/month) then you need to do 4,000 x 30 / 6 = 20,000. So you need the 20,000 subscriber plan even though you only plan to have 4,000 subscribers.
but apart from that, they let you import your list no problem.
