The “Lead Ads” function available in Facebook has an API structure that is not compatible for integration with SendReach. However they do have a facility for exporting leads in a .csv file, which can then be imported into a SendReach List.
That process does however bypass the “Re-Direct” function one usually uses as imports, as against normal subscribes, do not nor could trigger a Re-Direct. There is however an easy solution.
Set up an Autorsponder to go out to your List with NO delay, and set the “Include Imported Subsciber” function on the Campaign “Confirmation” Page to “Yes”. That Autoresponder needs to include a clickable link to your Re-Direct Page. You can easily motivate the new subscriber to click that link with some Free Offer available only when clicked – so it might say “Free XYZ here for download”.
If required, you can still forward variables to a Form on that Re-Direct Page seeking further Subscriber information, as described in http://setup.sendreach.com/forms/forwarding-variables-to-re-direct-page/ with the URL to that page added as a clickable link, to which you have added the variables, which might say something like “Please add your address for Free Coupon by post”.
That link URL could be something like mydomain.com/123.html/?email=[EMAIL]&first_name=[FNAME]&last_name=[LNAME] and your List would include fields for [ADDRESS1] and [ADDRESS2] and [CITY] and [ZIP] and set all but [ADDRESS2] as “required” to make them mandatory.
