Encode Special Characters for HTML Email
Encode characters like &, <, >, and © as HTML entities so they render correctly in all email clients.

Email tips
HTML email clients are strict. Unencoded & characters break rendering in Outlook. Always encode & as & in HTML email code.
Legal symbols like ©, ®, and ™ should be written as ©, ®, and ™ in email HTML for universal compatibility.
Em dashes (—) in email subject lines sometimes display as ? on certain clients. Use — in HTML body, but avoid in subject lines.
After encoding, test your HTML in Litmus or Email on Acid to confirm all characters render correctly across clients.
