Every email marketing journey begins with the email newsletter signup form. It is typically a popup, embedded box, or floating bar used to collect contact information from website visitors. A form offers website visitors the opportunity to exchange their contact details for something of value (updates, discounts, guides, VIP access).
Newsletter signup forms capture high-quality leads and help businesses grow an engaged email list. Such an email list helps drive sales via email marketing.
Newsletter signup forms help businesses to:
Looking at 779M+ widget impressions, newsletter signup forms convert at an average 3.53%. That benchmark alone makes them a reliable way to capture high-intent visitors — but the upside is much bigger. The top 1% of forms reach an average 27.53% CR, with the strongest examples climbing above 50%.
For instance, a well-timed newsletter signup widget often delivers higher CR, especially when paired with a clear call-to-action (CTA) and a compelling offer — this is particularly true for an email newsletter signup form used for list building.
In contrast, embedded newsletter signup boxes placed in blog content or footers tend to bring more consistent, long-term growth in email subscribers, supporting ongoing email marketing and lead capture via a newsletter signup form.
| How form configuration impacts conversion | ||
|---|---|---|
| Form configuration | Avg. CR | Why it performs this way |
| Email only | 2.48% | Minimal friction. Ideal for first-timers who aren't ready to share personal details yet. |
| Email + promo code | 3.85% | Visible, immediate value (the code) outweighs the “cost” of typing an email address |
| Email + exit Intent + promo | 5.76% | Catching a user exactly when they intend to leave, combined with a discount, doubles the conversion compared to standard popups. |
| Gamification + countdown | 16.13% | The “game” creates excitement; the timer pushes the user to claim the prize now. |
| Email + phone number | 1.0% | High friction. Asking for a phone number upfront signals high commitment and privacy risks. |
Newsletter signup forms are effective when used at various stages of the user journey to ensure they don’t feel intrusive while still offering value to users. Key use cases include:
A newsletter signup form is generally simple and straightforward. The design includes these basic components:
Let’s walk through setting up a newsletter signup form in Claspo that doesn’t just sit pretty but actually brings in subscribers.
Claspo offers plenty of newsletter sign-up templates, so you won’t be starting from scratch. They are already laid out with smart spacing, font sizes, and element placements to make sure your message looks great and reads well.
For this example, we’ll use a free newsletter signup form with radio buttons. It lets your visitors tell you exactly what they want to receive. It's an easy way to get started with segmentation and make sure your welcome email is delivered correctly.
Our drag-and-drop editor lets you adjust every part of your widget to match your site’s style. Change colors, fonts, sizes, shapes, and placement with ease. Just click any element — text, button, image — and its settings appear on the right.
Want to edit radio button text? Click on them, go to General > Edit options, and type in your changes.
You can upload your own images or browse through Claspo’s built-in library if you’re in a hurry. Got a multilingual audience? Claspo has you covered there, too. Just write your text in your default language, add any additional ones, and Claspo’s built-in AI translator will handle the rest. The system will then automatically show each visitor the right version based on their browser language.
Now, let’s tell your widget when to show up. In this case, we want it to appear after a visitor has spent a bit of time on your site — just enough to get curious, but not so long that they’ve already bounced.
To do this well, it helps to know your site’s average session time. If you’ve got that info, great — use it to set a display delay that makes sense. If not, don’t worry. You can stick with the default 20 seconds, which works well for most sites.
So, why wait? Because nobody wants to be hit with a signup form the second they land. Let your guests explore and understand what you have to offer. That way, when the newsletter signup form appears, they'll be more likely to respond and join up.
Last but not least, make sure all the data you collect goes where it needs to. Claspo integrates easily with the email and marketing tools you already use, like ESPs, CRMs, and CDPs. That means you can start segmenting, sending welcome emails, and triggering automations right from the first signup.

No matter what your goal is, there’s a widget for that. Explore pre-designed user-friendly templates and find the perfect fit for your next campaign.
Choosing the right form type directly impacts your list growth and conversions. We believe understanding these standalone strategies helps you build the perfect form for your key pages.
A simple form with just one field — the email address — and a clear CTA like “Subscribe” or “Join Now.” It minimizes friction for first-time visitors.
This newsletter signup form specifies what the subscriber will receive (such as weekly tips or guidelines). Framing the benefits in the copy helps to set clear expectations.
Uses urgency or exclusiveness to prompt action (e.g., “Be the first to hear” or “Don’t miss the drop”). It pairs well with limited-time offers.
Offers a reward (discount, free download) in exchange for an email. It is a high-performing standard for lead generation.
The layout includes checkboxes or dropdowns for content categories (e.g., promotions, events), allowing you to map interests right at the point of signup.
When creating a high-converting newsletter signup form, you need to balance UX with psychology. Based on the analysis of millions of successful campaigns, here are the essential best practices:
Even well-designed websites can fail to capture leads if they fall into these common traps:
Like with any widget, there isn’t just one “best” spot for newsletter signup forms. But there is one rule that fits all: Don't make users hunt for your form. Even though reading patterns vary by industry, you should always place your main sign up for newsletter form “above the fold.” This ensures you capture attention instantly before a visitor has a chance to scroll past. To capture engaged readers, use inline forms within blog posts. Behavior-triggered pop-ups (like exit-intent) catch users before they leave. Finally, a footer form is always a must. We recommend placing forms in different spots so that you can catch leads at any stage of their user journey.
Here is where email newsletter signup forms typically show the best results:
When your list isn't growing, it's likely due to a poorly visible form or an unappealing offer. In order to get more people to sign up, you need to have an incentive greater than just “regular updates.” First, offer a strong enticement to make it worthwhile to sign up for your newsletter — like a discount or a free guide. Then, to maximize visibility of your newsletter subscription form, don’t stick to just one location. Mix it up: put a bold newsletter signup form at the very top of your page, and another form inline within your blog posts. Last but not least, set up an exit-intent pop-up to save visitors right before theyleave your website.
You can find over 1,000 free, professionally designed templates for any case (including free newsletter signup form templates) in our Claspo Template Library or inside the platform itself while creating a new form.
No, not with Claspo. Claspo is a no-code widget builder. What this means is that you can create conversion-optimized widgets in minutes without ever having to write a single line of code.
Here’s our flow:
On average, it takes our users less than five minutes. You simply have to connect Claspo to your website once. Here are your options:
After this, any form you create and publish with Claspo will appear on your website.
Yes. You don’t need any coding skills to use Claspo. To change the newsletter signup form design, you can use the widget design panel in the Claspo editor and customize the form simply by clicking the required parameters. For example, you can change the form’s size, image on the background, spacing, button shape, text (font, color, and size), add GIFs as floating images, and much more. Our recent breakthrough is smart Theme generation that “sees” your website's color palette and automatically styles the form design to fit your brand seamlessly.
In short: any. You can connect Claspo to almost every major email platform or CRM. Sync instantly with popular tools like HubSpot and Mailchimp, or use Webhooks for everything else. Missing a specific integration? Tell us. We prioritize our development based on your requests.
Yes, absolutely. Once you connect your account, Claspo automatically sends every new lead from your newsletter signup forms to your CRM (integrations handle this in the background). This is why you can be sure that your sales team gets the data immediately, and you never need to export or import CSV files manually (though we do have a CSV option if you ever need it).
Yes, you can use both. For all the apps that aren’t on our one-click native list, you can use our Webhooks feature. This way, you can send your Claspo signup data to any of the thousands of other apps (like those on Zapier).
Yes, if your website supports JavaScript, it supports Claspo. This makes Claspo compatible with virtually any website. We have plugins for Shopify and WordPress. For everything else (like Wix or custom sites), just copy our script or add it through Google Tag Manager.
Yes, absolutely. Our widgets have been tested on all leading browsers to ensure that all of your visitors have a seamless experience.
Claspo provides you with responsive and mobile-ready newsletter signup forms, which automatically adapt to any screen resolution, from the largest computer monitor to the smallest smartphone screen. You can see and customize the design of the mobile form version in the process of building your email newsletter signup form. Leave it sync automatically or create an individual design for the mobile version.
Yes, it does. You can run split tests directly within Claspo to see how your audience responds to your signup forms. The built-in A/B testing feature lets you pit two versions of a form against each other (like testing a "10% Off" header vs. "Free shipping") and see which design or offer gets more signups.
Claspo provides all the features to make your newsletter signup forms comply with GDPR, but the final compliance depends on how you design and set them up. On our side, we make sure our newsletter signup templates have the required components on them and provide high-level data encryption.
A GDPR-compliant newsletter signup form requests explicit consent, avoids pre-checked boxes, and includes a link to your privacy policy. With Claspo, it’s easy to design such a form: find standalone components for collecting explicit consent and terms of use agreements in the builder on the left-side panel. Besides, you can verify users who sign up via double opt-in in your EMS, which is synced with Claspo.
Yes, it will help you increase conversion rates. Social proof elements serve as trust signals and reason users to sign up for newsletter form. For instance, you can use phrases like “Join 30,000+ marketers” or add a short review from a happy reader to your form. It will tell visitors that your content is valuable and worth their time.
To improve your signup rates and get more subscribers, your button text should talk about the reward or value the potential subscriber will get. For example, “Get the free guide,” “Join the VIP club,” “Get my discount.” Remember an old good rule of thumb: Your button text should answer the question “I want to…”
To get 100% protection from bots and fakes, it’s better to layer your defence:
On the first layer, reCAPTCHA will block automated scripts; field validation will catch typos; and finally, double opt-in will ensure every subscriber is real.
Claspo has built-in field validation, and you can enable double opt-in via EMS integration. Besides, if you’re a B2B company, you can toggle a setting to block generic domains like Gmail or Yahoo while setting up a newsletter signup form. This will help you get only high-value professional leads.
I installed Claspo to get an email newsletter popup when customers are getting ready to leave the page and it looks great! I also noticed that there are so many other popup options! It seems like it has the features of multiple apps all rolled into one. I'm looking forward to experimenting with all the options.

I have minimal experience with coding modern-day websites (basic HTML is all I know). My site runs on WordPress, but it's a "managed" version where I cannot add plug-ins whenever I want to. I was looking for an alternative to learning coding or paying someone to create a script to collect e-mail addresses for a newsletter.
Creating the pop-up in Claspo was SUPER easy. Once I found the script in Claspo and once I figured out how to insert it into my WP pages, it was very easy to add. It looks good and let me set the desired parameters.
My needs are simple (for now), so the free product is all I require at this time. I would have no qualms about subscribing if the need arises in the future.

I've been using Claspo for over a year, initially starting with the free plan and then moving to the paid one. Claspo has been a fantastic tool for displaying news and offers to our website visitors. I originally found Claspo through Stripo, the email editor we use. We switched from HelloBar to Claspo because it offered a larger selection of templates and features, which provided us with more flexibility and creativity when advertising on our website. The setup was incredibly easy, making the transition smooth for our team. The product is slightly less expensive compared to our previous solution, and it delivers great results. Claspo allows us creative freedom when displaying news and offers and offers numerous options on how and when to trigger these features, enabling us to effectively reach the right audience at the right time. I particularly appreciate the intuitive design and customization of popups. The builder is straightforward, and the targeting options are simple to use, ensuring that our marketing reaches the intended audience seamlessly. Since using Claspo, we’ve noticed an increase in subscriptions, clicks, and sales, leading to more engagement and newsletter sign-ups. The simplicity and reliability of Claspo, combined with its ability to deliver results, make it a product that I would readily purchase again. Overall, it's the easiest and most flexible tool I've tried for creating popups and bars on our websites, and they convert very well.
