Is there a way to implement background form submission as soon as a person clicks on the email?
Yes, but you do not want to do this.
Requiring deliberate interaction with a CTA form is the primary way of distinguishing humans from automated mail scanners.
If you do not require human interaction, then a mail scanner that follows a clicked link and loads the subsequent web page will also submit the form. Meaning the form submission is also automated.
What are you actually trying to accomplish at the business level? Let's start there.
I have a couple programs setup with auto form submissions. Most are for internal purposes like approving subscription requests. Those are very reliable since they are sent to employees. The only external one that I have is really setup for associating cookies. To actually kick off the SC the person has to click a link on the resulting LP (after the form is auto submitted). Sanford Whiteman would munchkin successfully associate the lead IF a scanner clicked the link and thus loaded the page submitting the form?
Sure, the form submission will associate the session as long as it has a Munchkin cookie. (Which it would if all trackers are loaded.)
