Easy Tech TutsHow to Import an HTML Email Template to Brevo Easily 2026
By Impran M N
If you already have a custom-built HTML email design, you don't need to rebuild it in Brevo's drag-and-drop editor from scratch. This guide shows how to open the raw HTML code editor, paste in your markup, and save it as a reusable template. It also covers keeping image sources hosted remotely so your file size stays within delivery limits.
01Start a new template
Go to Campaigns, then Templates, and click New template to set up your tracking name, sender, and subject line.
02Choose the HTML custom code option
On the design selection screen, click Start from scratch and select the HTML custom code editor card instead of the standard drag-and-drop builder.
03Copy your source markup
Open your custom-built email file in a text editor on your computer and copy the entire HTML code.
04Paste it into Brevo
Return to the Brevo code editor panel and paste your copied source code directly into the main code window.
05Save and test
Save the layout as a template with a clear name, then use Preview & Test to check how it renders across device sizes before saving for future campaigns.
Frequently asked questions
Is there a file size limit for HTML templates in Brevo?
Yes, it's best practice to keep your total email package under 1MB by using remote image links rather than embedded files.
Can I still edit my HTML template later using drag-and-drop blocks?
Custom HTML templates preserve your original coded structure, so editing is generally done by updating the raw code rather than switching to block-based editing.
Why would I use HTML code instead of the visual builder?
Custom HTML lets you preserve advanced structural rules and responsive frameworks that go beyond what standard drag-and-drop blocks support.
How do I check if my imported template displays correctly?
Use the Preview & Test feature to inspect how your code renders across major smartphone and desktop email clients before sending.
