Every website visitor is a potential customer, but without a way to capture their interest, that traffic goes to waste. An email signup form converts casual visitors into engaged subscribers by offering a frictionless way to join your list. It's a foundational tool in digital marketing that enables direct relationships with the audience.
Businesses rely on email signup forms for websites to:
Email signup forms can be added to virtually any touchpoint of the user journey — but performance depends on timing, placement, and relevance to the visitor. Common use cases include:

Let’s walk through how to create an email signup form in Claspo that not only looks good but also helps you grow your email list.
Claspo offers over 1,000 free templates, including email signup templates, so you don’t need to start from scratch. These templates are already optimized with smart spacing, font choices, and element layouts to help your message look great and perform well.
For this walkthrough, pick a newsletter email sign-up template that includes radio buttons. This gives your visitors the chance to choose the type of content they want to receive — a simple yet effective way to segment your email list from the start and personalize your welcome email.
The drag-and-drop form builder in Claspo allows you to customize every detail to match your brand. Want to change fonts, colors, shapes, or layout? Just click any element — like text, buttons, or images — and its settings will appear on the right-hand panel.
To update radio button labels, simply click on them, go to General > Edit options, and type your new text.
Reaching a global audience? No problem. Just write your text in your main language, add translations, and Claspo’s AI-powered translator will do the rest. Visitors will automatically see the right version based on their browser language — no manual setup needed.
Let’s make sure your pop-up form appears at the right time — not too soon, not too late. For this example, we’ll show the email signup form after the visitor has spent some time exploring your site.
If you know your average session duration, use that as a reference. If not, the default delay of 20 seconds works well in most cases.
Why delay at all? Showing a pop-up form the moment someone lands can feel intrusive. Let them browse for a bit and get a sense of your content first. When they’re more engaged, they’ll be more likely to subscribe to your email newsletter.
Finally, make sure all the data you collect through the sign-up form flows smoothly into your other systems. Claspo integrates with major email marketing platforms, CRMs, and other automation tools, so your new subscribers can be instantly added to your mailing list, receive welcome emails, and trigger campaigns — all automatically.

“We didn't just change form fields; instead, we focused on making sure the reward met the most important needs of our audience right now. For example, we looked at the differences between giving people cashback for signing up and giving them early access to special deals. As a result? When the incentive was directly related to the audience's financial goals, email sign-ups went up by 42%."

An email sign up form can fail to deliver results if it’s not thoughtfully built or implemented. Chances are you’ve already heard all the tips about design, copy, and CTAs. So, here are a few more profound insights on how to create an online sign up form that makes a difference in conversion rates and list quality.
Before creating any form, consider the context: what you’re offering, what data you actually need. For example, if you’re creating a newsletter email sign up form, there’s no need to overwhelm users with questions. A simple form with an email field works best in that case.
But if you're offering something gated, like a free guide or exclusive content, it makes sense to ask for more than just an email. The key is how you ask. Rather than displaying a long, overwhelming email list sign up form, use a multi-step format.
Claspo lets you build multi-step email sign up forms that break the process into smaller, user-friendly steps. First, capture the email. Then, on the next step, ask for additional details like name, role, or company. It feels more like a natural flow than a form, and users are more likely to complete it.
One of the biggest mistakes is assuming that when a user doesn’t sign up for the email list right away, the opportunity is lost. In reality, they might just not be ready yet. That’s where launchers come in.
Claspo allows you to add a launcher: a small, branded button fixed to the corner of the screen that reopens your email sign up form whenever the user chooses. If you're offering a welcome discount, this is an ideal way to keep the offer available without being intrusive.
Another great approach is to combine different formats. Alongside pop-ups, place embedded email list signup forms on high-traffic pages like blog posts, product pages, or your footer. Make your email signup page accessible from your navigation menu. Users engage at different times and in different ways, so combining options gives them more chances to say yes, without forcing the moment.
Trust is a key factor when it comes to collecting personal data. Users are more likely to subscribe if they know their information is safe and handled responsibly. That’s why it’s essential to clearly communicate that you respect user privacy and comply with major data protection regulations, such as the GDPR (General Data Protection Regulation) and the CCPA (California Consumer Privacy Act).
In Claspo, you can easily add a consent checkbox to your email list sign up forms—ideal if you’re targeting audiences in the EU, California, or any other region with strict privacy laws. Including this step not only builds trust but also protects your brand legally. A brief statement, such as “I agree to the privacy policy and terms,” can go a long way in increasing user confidence and boosting your conversion rates.
With Claspo, you can easily build high-converting email signup forms — and get started completely free. Our no-code solution enables you to launch quickly and test ideas freely, without relying on developers.
Use our mailing list signup form builder with flexible and advanced display rules to target the right users at the right moment. As a result, you'll attract more relevant subscribers, improve list quality, and build a mailing list that drives long-term impact.
