For accounts that have not qualified for, are not using, or for which the interaction does not permit single opt-in, a new subscription attempt always sends an opt-in confirmation email.

The dual opt-in message is defaulted by FeedBlitz. Its content is fixed; its formatting depends on the list’s active template and whether or not a SmartForm was used to generate the subscription (in which case the SmartForm’s design is used to format the activation email).

The HTML sent can be overridden as a custom registration email. The content you create will be wrapped by the appropriate template (list or SmartForm).

A custom registration email must contain the special tag <$BlogSubLink$> (suitably encoded). FeedBlitz will insert the activation URL using that tag as the placeholder. It does not create an anchor (<a> tag), just the URL.

The following resources are supported.

Resource:        /customreg/<listid>

Methods are: GET, POST, DELETE.

POST creates the alternative; if you DELETE the entry, FeedBlitz reverts back to the default for the specified list.
