I haven't ever flown United, but have the Explorer card and flew on Copa metal a bit last year (credited miles to my United account). No email, but signed up through the link:
$500 - 8,000 miles
$1,000 - 12,000 miles
$2,000 - 20,000 miles
Girlfriend has also traveled on Copa metal last year and no United flights, no Explorer card either. She got the same exact offer.
