Tracking/Analytics for Clicks from T-Brid
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?
