WordPress Pre-Footer Email Opt-In

My WordPress site is almost wrapped up; the last piece is a polished, professional-and-corporate pre-footer section that invites visitors to join my list. I have already built the form in ActiveCampaign and can hand over the embed code or direct link—your job is to drop it into the site, style it so it blends seamlessly with the current branding, and make sure it works flawlessly on desktop, tablet, and mobile. The form needs three fields—first name, last name, and email—mapped correctly to ActiveCampaign so every new contact lands in the right list with no duplicates or formatting issues. Beyond that, I’m aiming for clean lines, understated colors, and typography that matches the rest of the site’s corporate look. No flashy graphics or animations, just a well-considered block that feels trustworthy and professional. Please: • Insert and style the opt-in section just above the footer on every page. • Align fonts, button shapes, and spacing with existing theme settings (custom CSS is fine). • Test the connection to ActiveCampaign, confirm each field passes data accurately, and run a live signup test. • Ensure the section remains responsive and ADA-conscious. Once complete, send over a brief summary of what you changed, any custom CSS or theme edits, and confirmation that the signup test succeeded. That’s it—clean, functional, and ready to capture leads.
