The subscription procedure at Zinester.com is double opt-in. This
means users will be asked to reply to a confirmation message after
they request subscription via email.
The well-known problem with double opt-in is the low percentage of
confirmation received from users. The common trouble with
majordomo-alike interfaces is that confirmation messages are not
processed correctly when modified by the email client during reply.
This problem does not exist with Zinester - all the necessary
confirmation info (ticket) is placed to the "From" field of the email
message. No matter what transformations happen to the body of the
message, the confirmation will be processed.
Email subscription and unsubscription links are automatically added to
the bottom of the messages in the free version of the service.
