// Hello! welcome to the settings page.
// Here's your two steps guide:

// FIRST: 
// Instead of newsletter@test.com put the email address of the mailing list,
// (the same that SendBlaster uses in Manage Subscriptions Section)
// ... please pay attention to the  ' ' apostrophes, they must remain around the email address.

$emailmanager = 'newsletter@test.com';

// SECOND:
// save this file, and close it. Thank you!
