How to Import a Custom HTML Email Template into Brevo

2026-03-054 min read

Using custom HTML in Brevo

Brevo (you might remember it as Sendinblue) has a solid drag-and-drop editor, but it can't fully replicate your brand's unique design. For that, you need custom HTML.

SiteToSend generates a Brevo-compatible template that captures your website's visual identity. Here's how to get it set up.

Step 1: Download your Brevo template

Head to your SiteToSend dashboard and click the Brevo download button on your order. The HTML file you get works with Brevo's template system out of the box.

Step 2: Go to your Brevo templates

Log into Brevo and navigate to Campaigns > Templates. Click New Template and select Code your own (sometimes labeled "Paste your code").

Step 3: Paste the HTML

Open the downloaded file in a text editor, copy the full contents, and paste it into Brevo's HTML editor. You'll see a live preview update as soon as you paste.

Step 4: Update the content

Work through the template and replace the placeholder content:

  • Update images with URLs from your own hosting or Brevo's media library
  • Change the headline and body text to match your campaign
  • Adjust button text and link destinations
  • The unsubscribe link and contact details use Brevo's built-in tags, so those should already be set

Step 5: Save and send a test

Click Save & Quit to store your template. Before using it in a real campaign, go to Preview & Test and send yourself a test email to double-check everything.

Helpful notes

  • Brevo's free tier supports custom HTML templates with up to 300 emails per day. That's plenty for testing and smaller campaigns.
  • Transactional emails too: If you also use Brevo for transactional emails (order confirmations, password resets, etc.), you can adapt this same template for those as well.
  • Dynamic lists: Brevo's personalization tags like {{ contact.FIRSTNAME }} work inside your custom HTML. Drop them in wherever you want personalized content.
  • Mobile preview: Use Brevo's preview toggle to check the mobile version. Your SiteToSend template is responsive, so it should look good, but it never hurts to verify.
