Encoding HTML for Email Templates
Email clients are unforgiving about malformed HTML. Encoding entities correctly keeps templates rendering as intended.
Escape dynamic content
Any value inserted into an email template — names, subjects, user input — should be entity-encoded so an ampersand or angle bracket does not break the markup or display oddly.
Inspect before sending
Decoding a template snippet lets you read it as the recipient will, while encoding lets you safely include literal characters. Both help you catch rendering issues before a send.
