I just sent about a hundred emails from Thunderbird, with one To: (me), and the rest Bcc.

Is there a way to know if

1. the email was read
2. if they clicked the link in my email, which goes to my affiliate's page, and only has an opt-in.

I know in my dashboard I can see total unique visitors and total optins, but I don't know where they came from.

Can I find this out with Thunderbird? Should I be using a different program, beside mailchimp or constant contact, instead?
