And following up on my own post, here are the relevant terms and conditions:
Note: I choose Delta miles - if you pick another airline, that will be where the submit your miles.
# Members must respond to at least one marketing message per month for their e-Miles miles to remain active. e-Miles reserves the right to suspend a Member's e-Miles miles if such Member does not respond to at least one marketing message per month. The decision to suspend e-Miles miles will be at e-Miles discretion.
# e-Miles miles are automatically submitted to Delta Air Lines for deposit into SkyMiles Bonus Miles within 30 days after the end of each calendar quarter for qualifying e-Miles increments.
# e-Miles miles are deposited in 500 mile increments with overages rolling into the next quarter. e-Miles reserves the right to change the increments and/or frequency of deposits.
# e-Miles miles not deposited into your SkyMiles account expire one year after the quarter in which they were earned.
For answering the beginning stuff and my signup bonus I got 295 miles.
