I've been sweeping since April, 08. I'm using my roadrunner email with internet explorer. On many of my instant wins especially with eprize I have not been receiving the conf email. I've contacted RR & Eprize concerning the matter. Eprize states there were some technical issues but have been cleared up & have sent the conf emails to me & RR says some emails get kicked back to the company if they appear to be spam & also sometimes their server is down. With sweeps such as Burger King & Subway I had to start using my yahoo email because I wasn't receiving any emails/codes from them with RR/Internet Explorer. My husband recently started sweeping using his yahoo acct & I've noticed he gets 3 X the confirming entry emails I'm getting. My concern is if I'm a winner & they notify me via email, but because it looks like spam it gets kicked back to the company! OMG, that would be awful. Losing a sweep I didn't know I'd won! I do between 250-300 sweeps a day & on many of them once you're registered under a certain username/email, there is no way to go in & change your email w/o changing the username. If I did that I'd afraid it would become a sweeping nightmare & disaster. I know many of you must use RR/Internet Explorer, have you had any problems... or am I just overreacting?
