Put this snippet in a file in a templatetags/ directory and load it in your templates. Then use it to encode your emails:

{{"email@example.com"|html_encode_email}}

Or if you want some control over the anchor tag:

<a href="mailto:{{"email@example.com"|html_encode}}&subject=Feedback">Send Feedback</a>
