Tips for HTML emails
HTML emails require a different approach than web development. Email clients have inconsistent CSS support, so table-based layouts and inline styles remain the most reliable approach.
Keep your email under 102 KB — Gmail clips messages that exceed this size, hiding content behind a "View entire message" link. Use inline CSS instead of stylesheets, and test across multiple clients.
Always include a plain-text version alongside your HTML. Some recipients prefer it, and spam filters look favorably on multipart messages.
