Hey just signed up for free weekly. Cool idea! First - you did get classified as spam in my gmail. I feel for you because I recently launched something small, carefully completed my SPF and DomainKeys DNS stuff in Mailgun, and ended up in the same exact boat. Gmail SPAM folder. Maybe you and I should call Gmail's phone support number to discuss with them. Hahahaha.

Second - I clicked the activation link and when I went to my dashboard the default state was 'disabled'. You might want to make that 'enabled'.

Good luck!
