Embed customizable, high-converting signup forms with optional double opt-in to grow a qualified, engaged subscriber list across your site and pop-ups.
Every subscriber starts with a form. OptiPub’s subscribe forms are built to convert — customizable, embeddable anywhere, and protected by double opt-in and bot defenses, so the list you grow is a list that actually engages.
High-converting, customizable forms
Design sign-up forms that match your brand and are built to convert. Embed them inline, as pop-ups, or across your site and landing pages to capture subscribers wherever your audience shows up.
Optional double opt-in
Turn on double opt-in to confirm every new subscriber, keeping your list clean, engaged, and compliant from the very first email.
Clean and protected by default
Forms come backed by Bot Protection and Email Verification, so fake and invalid sign-ups never make it onto your list in the first place.
What you get
