What is an HTML email template?

If you ask what is html email, the short answer is: a self-contained HTML file where layout lives in nested <table> tags, every visual rule is inline, and the main content column is about 600px wide. An html email template is that same structure saved as a reusable starting point for newsletters, signatures, or vacation replies.

Why is an HTML email template not a webpage?

Browsers and email clients parse HTML with different rules. Gmail removes <style> blocks in many contexts, Outlook uses Word's rendering engine, and Yahoo strips scripts. A template built like a landing page will break in at least one major client.

• Layout: Tables with border="0" cellpadding="0" cellspacing="0", not flex or grid. See why div layouts fail.
• CSS: Inline style="" on each element. External sheets are blocked. Read inline style patterns.
• Width: A fixed inner table around 600px inside a fluid outer wrapper. Details in container width.
• Head: No <title> tag. Gmail vacation responder prints it as visible text above the body.

How do I design an HTML email?

Start with structure before color. Sketch sections as rows in a single-column table, then add a header image, body copy, CTA button, and footer. Buttons are table cells with a styled <a>, not CSS-only divs.

• Pick a 600px content width and stick to it for images and text blocks.
• Use web-safe fonts: Arial, Helvetica, Georgia, Verdana.
• Set explicit width and height on images to prevent layout jump.
• Test in Gmail web, Outlook desktop, and a phone before you send.

For responsive two-column sections, use the hybrid table pattern in our responsive email with tables guide.

What does an HTML email example look like?

Real templates combine a hero image, short headline, body paragraphs, and a single CTA. Below are two built-in examples from the html2email extension gallery: a modern newsletter and a vacation auto-reply.

• Header row with logo or hero image
• Headline and intro copy in a padded cell
• CTA button built from a table cell and styled link
• Footer with unsubscribe or contact details

Both follow the same skeleton: outer 100% table, inner 600px container, rows for each content block. Variable placeholders like {{name}} are covered in template variables.

What are HTML email best practices?

These rules keep templates stable across Gmail, Outlook, Apple Mail, and Yahoo.

• Inline all CSS. Do not rely on class selectors alone.
• Use role="presentation" on layout tables for screen readers.
• Include alt text on every image.
• Add a plain-text fallback when your ESP supports it.
• Validate border, cellpadding, and cellspacing on every table. See table attributes.
• Pick the right HTML email DOCTYPE for Outlook compatibility.
• Keep total HTML size under ~102 KB. Gmail clips larger messages per Google's size limits (attachments allow up to 25 MB, but the body has a separate ceiling).

• Send a test to yourself and check images, links, and width on mobile.
