On our WordPress website we have multiple forms that sign users up to different newsletters. Most users are only interested in one newsletter (each form subscribes to a specific newsletter), however sometimes they choose to sign up to 2 or come back at a later time to sign up for another newsletter.
The initial signup works fine, however when they subscribe to another newsletter it deletes the first subscription and only keeps the new selection.
We want to keep both.
I am currently using Constant Contact API Version 2.3.9 plugin.
The short code I am using is
[constantcontactapi formid="0" redirect_url="http://xxxxxx.com.au/privacy-policy/thanks-rw-enewsletter" lists="29"]
Any help most appreciated.
