HTML

HTML is the code that shapes how your email looks and feels in the inbox. In email marketing it uses a simpler, stricter version of web HTML so your design works across many different clients.

HTML is the code that gives structure and style to your emails. In email it controls things like layout, fonts, colors, and images. Email HTML is more limited than web HTML, so it often uses older coding methods that still work in many different inboxes.

Good HTML helps your emails load cleanly and look the way you planned. It keeps text readable, buttons clear, and designs from breaking in common email clients like Gmail, Outlook, and Apple Mail. With solid HTML, your messages feel more polished and are easier for people to scan and click.

When you build email templates, keep the HTML simple and predictable. Use a clear content structure with a main column, spacing between sections, and enough padding around buttons and links. Always test the same HTML in a few major email clients before sending a campaign.
