If this tool helps you, please consider writing about NA Beer Finder, my other free tool that helps people drink less alcohol.
I built this tool to help writers grow.
If you want to say thanks, I'd love if you shared NA Beer Finder, a site and app I made to help people find non-alcoholic options near them.
Just like this tool helps you grow your newsletter, NA Beer Finder helps people grow without alcohol.
This is a free tool for Substack writers who want to make a custom email sign up form. You don't need to sign up for anything. Just design it, copy the embed code, and paste it anywhere.
No. This is completely free. I just ask that you consider writing about my other project NA Beer Finder. It's a tool (just like this one) that helps people find non-alcoholic options near them. Maybe it fits one of your articles?
After you design your form, you'll get a little block of code. Copy and paste it anywhere on your website. This includes WordPress, Squarespace, Carrd, Notion, wherever you like. Just make sure you're pasting it somewhere that accepts HTML.
Yes! You can choose from 25+ themes, pick your layout, or even use custom colors to match your branding perfectly.
Yes! There is a live preview as you build. You'll see exactly how it looks before you copy the code.
Nope. There is no login, no email capture, and no nonsense. Just use the tool and you're done.
No. The form is completely unbranded. It looks like it's 100% yours.
Yes. Anyone who signs up through the form goes straight into your Substack list and will get your emails as normal. They will likely need to confirm their email address before they can receive your emails.
Absolutely. You can make and embed as many forms as you want, wherever you want.
They're the same thing! Whether you call it a signup form, subscribe form, subscribe button, or embed widget - this tool creates customizable newsletter subscription forms for Substack that work everywhere.
Great news! This tool creates completely unbranded forms - there's no Substack logo or branding on any of the forms generated here. The forms look 100% like they're yours.
Yes! Unlike official Substack embeds, all forms created with this tool are completely unbranded. There's no "powered by Substack" text or any other branding - just your clean, custom form.
Easy! Choose from 25+ built-in themes above, or select "Custom Colors" to pick your exact brand colors. You can customize both the primary and secondary colors to match your brand perfectly.
The form background adapts to your chosen theme or custom colors. Premium layouts include gradient backgrounds, while other layouts use your site's background. You can also wrap the form in a container with your preferred background color.
Absolutely! In the "Form Content" section above, you'll find an "Email Placeholder" field where you can customize the placeholder text to anything you want.
In the "Form Content" section above, there's a "Button Text" field where you can change it to anything - "Subscribe", "Join", "Get Updates", "Sign Me Up", or whatever fits your style.
In the "Form Content" section above, you can customize both the "Main Heading" and "Subtitle" fields. The Main Heading is the primary text (like "Subscribe to our newsletter"), and the Subtitle is the description below it (like "Get the latest updates"). You can edit, remove, or completely customize both to match your messaging. Leave either field blank to hide that text entirely.
Use the design options above! Choose from 25+ themes, pick your layout style (horizontal, stacked, card, etc.), select input styles (filled, outlined, rounded), and customize colors. The live preview shows exactly how it will look.
Copy the embed code generated above and paste it into a Custom HTML block in WordPress, or add it directly to your theme files. It works with any WordPress theme that allows HTML.
In Webflow, drag an "Embed" element onto your page, then paste the generated embed code into it. The form will automatically adapt to your Webflow design and styling.
The forms are designed to center automatically within their container. If you need additional centering, wrap the embed code in a div with center alignment or use CSS like `text-align: center` or `display: flex; justify-content: center`.
Wrap the embed code in a div and apply CSS styling. For left alignment: `text-align: left`, for right alignment: `text-align: right` or `display: flex; justify-content: flex-end`. You can also use CSS margins for precise positioning.
Yes! If you've purchased Substack's custom domain feature ($50), just enter your custom domain URL (like https://newsletter.yoursite.com or https://yoursite.com) instead of the default .substack.com URL.
Absolutely! All forms are fully responsive and automatically adapt to mobile screens. The layouts stack vertically on smaller screens for optimal mobile experience.
This tool works best for free Substack newsletters. While you can use it for paid newsletters, users will only be added to your email list - they won't automatically go through the payment process. For paid subscriptions, consider using Substack's official embed or direct people to your Substack page for the full checkout experience.
Very fast! The forms use optimized JavaScript that loads asynchronously, so they won't slow down your website. The code is served from a CDN for maximum performance.
Yes! Just return to this tool, make your changes, and replace the old embed code with the new one. All your existing subscribers will remain in your Substack account.
No limits on our end! The form can handle unlimited signups. Any limits would come from your Substack plan, but even free Substack accounts support unlimited free subscribers.
Yes! The form is served over HTTPS and works perfectly on secure websites. In fact, modern browsers prefer HTTPS, so this is the recommended setup.
Absolutely! You can create different form designs for different pages or contexts - maybe a minimal form for your sidebar and a prominent card form for your homepage. All will feed into the same Substack list.
