Newsletter signup forms

Embed a newsletter signup form on your website to grow your subscriber list.

You can embed a newsletter signup form on your website so visitors can subscribe to your mailing list directly. Sailia generates the embed code for you — copy it and paste it into your site’s HTML.

How it works

When a visitor fills in your embedded form and submits it, they are automatically added to your audience in Sailia. You can then reach them through marketing campaigns and automated workflows.

The form collects:

Field	Required	Description
Name	Yes	The subscriber’s full name
Email	Yes	The subscriber’s email address

Subscribers added through the form are marked as opted-in for marketing communications.

Get the embed code

1. Open the audience page

   Navigate to Marketing > Audience in your Sailia dashboard.

2. Open the newsletter form dialog

   Select the newsletter form option to open the embed code dialog. You will see a live preview of the form alongside the embed code.

3. Customize the button color

   Use the Button Color picker to match the form’s submit button to your website’s branding. The preview updates in real time as you adjust the color.

4. Copy the embed code

   Click Copy embed code. The code is copied to your clipboard.

5. Paste into your website

   Open your website’s HTML editor and paste the code where you want the form to appear. Save and publish your page.

Customization

The embed code generates a styled form that works on any website. You can customize:

Option	How to configure
Button color	Set in the embed code dialog using the color picker
Placement	Paste the embed code in your website’s sidebar, footer, header, or as a standalone section

The embed code is a self-contained HTML snippet. It works on any website that allows custom HTML, including WordPress, Squarespace, Wix, and static sites. Advanced users can style the form further by targeting its CSS classes in their website’s stylesheet.

Where to place the form

For maximum signups, consider placing the form in high-visibility areas:

• Homepage — above the fold or in the footer
• Blog posts — at the end of relevant content
• Activity pages — alongside descriptions of upcoming events
• Pop-ups or slide-ins — if your website builder supports them, trigger the form after a visitor has been on the page for a set time

If the copy button does not work in your browser, select the code manually from the text area and copy it with your keyboard.

After embedding

Once the form is live on your website:

• New subscribers appear in your audience automatically
• You can segment and target subscribers using audience filters when sending campaigns
• Subscribers can unsubscribe through the link included in your marketing emails

Privacy and consent

The newsletter form is designed with email marketing best practices in mind:

• Explicit opt-in — visitors actively choose to subscribe by filling in the form and clicking the button
• Unsubscribe link — all marketing emails include an unsubscribe link, so subscribers can opt out at any time
• No pre-checked boxes — the form does not subscribe visitors without their explicit action
• Data access — subscribers appear in your audience list where you can view, export, or delete their records

You are responsible for ensuring your use of the signup form complies with applicable data protection regulations (such as GDPR or PECR) in your region. If you need to collect additional consent text or disclosures, add them to the page surrounding the embedded form.

Resubscribing contacts

If a previously unsubscribed contact fills in your newsletter form again, they are automatically resubscribed and begin receiving marketing emails. See resubscribing contacts for details.
