Email marketing glossary

Bulletproof (buttons and backgrounds)

In email development, bulletproof buttons and backgrounds refer to buttons and backgrounds coded in HyperText Markup Language (HTML). Instead of relying on email clients to properly render image-based buttons or backgrounds, bulletproof buttons and backgrounds consist of HTML and Cascading Style Sheets (CSS) styling that consistently render across email clients. Brands use bulletproof buttons and backgrounds to create email content that displays correctly regardless of the receiving email client, boosting brands’ engagement and conversion rates.
