Gmailzero - let me go

I signed up for the gmail0 beeminder goal yesterday to see how it works. Now I have 15 emails from beeminder in my inbox asking me to read 4 emails. And 10 of these beeminder emails arrived within a span of two hours (9-11 AM)! Definitely not my cup of tea. How does one drop a goal in beeminder? None of the questions in their FAQ seem to address this. I have modified the goal, so that my goal instead of 0 unread emails is now 100,000 unread emails!
