Permission required to use this feature: Lists and subscribers > add new subscribers
Signup pages are standalone web pages with unique URLs for attracting new subscribers. They don’t require hosting—we handle that for you. You can easily share your signup page online or include it in your email signature.

How to create a signup page
- Click Lists & subscribers, then click on the relevant list name.
- Click Signup form builder in the left menu.
- Select Create a signup page from the options listed.
- Use the editing tools to customize your form and then click Save.
Customizing the signup page
Use the built-in tools to adjust the design and layout of your form to match your branding. You can preview your form on the same page—data entered in the preview will not be saved or added to your list.
To share your form, click Share to open your live signup page. Any completed submissions on this page will be added directly to your list. Remember, changes to your form that are visible in the preview will not appear on your live signup page until you save them.

Under this tab, customize the sign up form displayed to potential subscribers. Note that this tab will need to be selected to access the Fields and Options sections, which we'll cover later in this document.
Page
Choose between a single layout, or split the layout into sections.
- For the single layout, you can display a box around your form content or not.
- For split layouts, you can customize how your form’s content is displayed within the sections. Text and form elements can be grouped into the same section, or displayed in separate sections. Optionally add padding to sections, or adjust the corners of the sections.
Background
Set the background color and transparency level for each section. You can also add a background image by uploading a file or linking to an image URL. Supported file types: .jpg, .jpeg, .png, .gif.
Optionally upload a header image to appear above your form’s heading. Adjust the image size and alignment as needed.
Heading
Customize the heading text by selecting a font family, font size, text color, and alignment.
Description
Add an optional description to your form and customize its font family, font size, text color, and alignment.
Label
Set the font family, font size, and text color for labels used in text fields, select menus, and checkboxes.
Field
Customize the background color and text color of your form’s text fields and select menus.
Personalize your button by setting the text, font family, and font size. Customize its background color, text color, corner style, width, and choose between Solid or Ghost preset styles.
Checkbox
For forms with multiple options (select many) custom fields, multiple list opt-ins, or permission options, customize the checkbox font family, font size, and text color.
Link
If your form includes policy links, you can adjust the font family, font size, and text color.
Success Page
Under this tab, customize the message displayed to subscribers after form submission. Adjust the heading text, message text, and the font family, font size, text color, and alignment of each.

Fields
You can access this section while the 'Form' tab is selected.
If your subscriber list includes custom fields, they will appear below the default Name and Email fields. To add more custom fields, click Add new field.
Select the fields you want to include on your form, and check the Required box to make them mandatory. You can also reorder custom fields by using the drag handle on the left to move them up or down.
Options
You can access this section while the 'Form' tab is selected.
Opt in to multiple lists
You can add multiple lists to your signup page, allowing subscribers to opt into more than one list. If lists share custom fields with identical names and types, the data will automatically populate across all selected lists.
To avoid confusion, ensure that all included lists use the same opt-in type—either all confirmed opt-in or all single opt-in. For confirmed opt-in lists, subscribers will receive a single confirmation email covering all selected lists.
Permissions and policies
You can display checkboxes for email and tracking permissions and customize their labels, allowing subscribers to opt into email communications and tracking. This lets potential subscribers explicitly choose whether they want to receive emails and allow tracking of email opens and clicks.
Additionally, you can include links to your privacy policy and cookie policy.
Language
Changing the language setting updates default field labels Name and Email, as well as error messages.
However, all other content must be updated manually:
- Custom field labels – If the field names are in English, they will appear in English on your form. To edit custom fields, go to your subscriber list page and click Custom fields in the left sidebar.
- Editable text – Any default text in editable fields, such as the heading, description, and labels for permissions and policies checkboxes or links, will not automatically update to your selected language. Be sure to manually update this text in the signup form builder to match your chosen language.
- Verification email content – This applies to confirmed opt-in lists. The verification email sent to subscribers is in English by default. To edit this email, open your subscriber list page, click Settings in the left sidebar, then under Subscribe options, click Edit next to Confirmed opt-in email.
Mobile number and SMS consent
If SMS campaigns are enabled, you can add a Mobile Number field and an SMS Marketing Consent checkbox. See Collecting mobile numbers to grow your SMS subscribers for more details.
Signup form builder update
We've enhanced our signup form builder with new layout and flexibility features. As a result, signup pages created with the previous version must be converted to an updated template format.
If you see an update message when opening an existing signup page, follow these steps:
- Review the form preview carefully
- Ensure all elements appear as intended
- Make any necessary adjustments
- Save your design
Taking a moment to verify your signup page’s appearance will ensure a smooth transition to the new format and maintain an effective signup process for your subscribers.
