You can Base64 encode the email address in your email preference center by using the Base64 Iterable Merge Tag.

Your Preference Center URL will look like this:

https://pref.domain.com?email={{#base64}}{{email}}{{/base64}}

You will paste this URL into the Hosted Preference Center section in Iterable,

If you also want to encode the locale/language field in a Multilingual Preference Center, your URL will look like this:

https://pref.domain.com?email={{#urlEncode}}{{#base64}}{{email}}{{/base64}}{{/urlEncode}}&language={{#urlEncode}}{{locale}}{{/urlEncode}}
