Then when the person sent and email they we're automatically put on a single opt in list. (they could also be send a double opt in email)
And with the single opt in via email they got a 10x greater response vs sending people to a squeeze page.
Anyway they said that with aweber the double opt in is the only way you're allowed to collect leads via email.
They didn't mention which service let's you collect leads directly from them sending an email.
Does anyone know what auto-responder services let you?
I hope some of you can grow your lists with this method and thanks in advance for the site recommendations.
