Email formatted using HTML code to include visual design, images, colors, and styled text, as opposed to plain text emails containing only unformatted content.
HTML email enables branded, visually engaging email communications that reinforce brand identity and improve content scannability through design hierarchy. Financial services marketers use HTML email to create professional newsletters, promotional campaigns, and automated sequences that match website aesthetics and enhance message effectiveness.
HTML email design requires careful attention to email client compatibility, as different providers (Gmail, Outlook, Apple Mail) render HTML differently. Responsive design ensures emails display properly on mobile devices where most email is now opened. Balancing images with text maintains accessibility for recipients with images disabled while avoiding spam filter triggers from image-heavy emails.
For example, a wealth management firm might send HTML newsletters with market commentary, featured articles, and event invitations organized in visually distinct sections with branded colors and typography. A bank could use HTML email for product announcements with product images, benefit callouts, and prominent CTAs. A financial advisor might send HTML prospecting emails with professional headshots, client testimonial quotes, and calendar booking buttons.
Best practices include concise design optimized for quick scanning, single-column layouts for mobile compatibility, careful file size management for fast loading, and thorough testing across email clients before sending. Fallback plain text versions ensure deliverability when HTML rendering fails, and plain text alternatives often improve deliverability by avoiding spam filters.
