How to Add Email and SMS Signup Forms to Your Site
Why Signup Forms Matter
Most website visitors leave and never come back. Signup forms capture their contact information so you can reach them again through email or SMS. Even a simple email capture form on your homepage can convert one to three percent of visitors into subscribers. Over time, these subscribers become your most valuable marketing channel because you own the relationship directly, without depending on search engines or social media algorithms.
Step-by-Step Setup
Decide whether to collect email addresses, phone numbers for SMS, or both. Email-only forms are simplest and have the lowest friction. SMS forms require opt-in compliance language. Dual forms that collect both email and phone give you two channels to reach each subscriber. See How to Set Up Dual SMS and Email Opt-In for the dual approach.
The Web Builder app includes form blocks for both email newsletter and SMS newsletter signups. These forms submit to the platform's API endpoints, which automatically add new subscribers to your contact list in the Email Broadcast or SMS Broadcast app. Add the form block to any page you build in the Web Builder.
The text around your form matters as much as the form itself. Tell visitors what they will receive ("Weekly tips on growing your business") and how often ("Every Tuesday morning"). Set clear expectations so subscribers know what they are signing up for. Avoid generic text like "Sign up for our newsletter" which gives no reason to subscribe.
Put signup forms where they will be seen by the most visitors. Your homepage, blog post pages, about page, and any page that gets significant traffic should have a signup form. The form does not need to dominate the page. A simple inline form at the end of blog posts catches readers who just consumed valuable content and are primed to subscribe.
When someone subscribes, send them an immediate welcome email or SMS confirming their subscription and delivering whatever you promised. This first message sets expectations for future communications and confirms that the subscription is working. Set this up as the first message in a welcome drip sequence.
Form Placement Strategies
Inline Forms
Embedded directly in your page content, typically at the end of blog posts or articles. Inline forms feel natural because they appear as part of the content flow. Visitors who read to the end of an article are already engaged, making them more likely to subscribe.
Header or Footer Forms
A persistent signup form in your site header or footer appears on every page. It catches visitors regardless of which page they land on. Keep it compact, usually just an email field and a submit button with a brief value proposition.
Dedicated Signup Pages
A full landing page focused entirely on getting signups. These work well as destinations for social media links, email signatures, and paid ads. The dedicated page can include more detail about what subscribers receive, testimonials from existing subscribers, and sample content.
SMS Opt-In Compliance
SMS signup forms require specific compliance language. You must clearly state that the subscriber is opting in to receive text messages, how often they will receive messages, and that message and data rates may apply. Include a link to your terms of service and privacy policy. See How to Set Up Proper SMS Opt-In and Opt-Out and TCPA Compliance Guide for detailed requirements.
