Email open rate

Hey all, I just started email marketing and building my list. I made a squeeze page, thank you page, and download page. I just bought a solo ad package of 100 clicks which has done about 65 clicks so far. I've gotten 26 subscribers so far. My issue is I'm not sure anyone is opening the welcome email which has the download link... I'm almost positive.

After they opt-in, I send them to my thank you page which tells them the download link will be emailed to them shortly and provide a bonus link to a PPL program I have signed up for. I've gotten about 25 people who have clicked the link to that bonus and about 14 signups. When I check the link stats for my download page, theres only 4 hits (2 of which I think are me). Aweber says that my open percentage for my welcome email is 42%. When I was testing everything out, I would opt-in using my email and open the emails to make sure the link worked and everything was setup how I wanted it. I sent maybe 10 emails or so.

I click the link and it sends me to my DL page no problem (and using the link tracker). The welcome email also wasn't sent to my spam folder and has a 0% spam rating on Aweber. I'm sending from my domain email address and when I was testing the opt-in I was using a gmail account.

If anyone has any clue or ideas of whats going on, I'd appreciate it.
