EMAIL MARKETING / SMALL-BUSINESS GUIDE
How to Embed a Brevo Signup Form on Your Website
Add a Brevo newsletter signup form to your small-business website. Learn how to embed it, turn on double opt-in, and test the full signup on your phone.
For a typical small-business site, start with Brevo’s iframe embed. You’ll create the form in Brevo, paste the embed into an HTML block on your website, and verify that a visitor can confirm their email and land in the right list.
01 / FORM
Create your Brevo signup form
In Brevo, open Marketing → Forms. On the Sign-up tab, choose Create sign-up form, then Full page/embedded. Give the form a name you’ll recognize later, such as “Website newsletter signup.”
Keep the visible fields simple. An email address is enough for most newsletters. Tell people what they’ll receive, and pick a dedicated newsletter list in the form’s list settings so you can easily verify where new subscribers land.
02 / CONFIRMATION
Turn on double opt-in
In the form’s settings, choose Double confirmation email and select Brevo’s default double opt-in template to get started. After someone submits the form, they’ll need to click the link in their confirmation email to join your list.
Tell people what to do next in the submission message or on your confirmation page. A simple line works well. “Check your inbox and click the link to confirm your subscription.”
03 / WEBSITE
Embed the Brevo form on your website
On the form’s Share step, copy the Iframe code. Paste it into your site’s HTML or embed block. On WordPress, look for a Custom HTML block. On Wix, look for Embed HTML. If your builder blocks embeds, use the public form link from the Share step as a button destination.
Give the iframe a descriptive title, such as “Newsletter signup.” Preview the page at phone width and adjust the embed’s dimensions so the submit button and any confirmation message fit. Brevo also offers HTML embed options for sites that need more control over the styling.
04 / LIVE TEST
Test it like a new subscriber
- Open the published page on your phone and submit an email address you control that’s new to the list.
- Open the confirmation email and click its link. Check your spam folder if the email takes longer than expected.
- Verify the address is in the intended Brevo list. If you’ve set up a welcome email or offered a download, check that it arrives too.
If the form submits but the address doesn’t appear, check whether you clicked the confirmation link, then verify the list selected in the form settings.
