What is he best way to pre-populate the email address in unsubscribe page?

Just what the title of the post is; "What is he best way to pre-populate the email address in unsubscribe page?"  The most basic common courtesy of any email marketing campaign.

Enable Pre-Fill for the field, as with any field.

If the field isn't on the form, use a token.

I'm looking for comprehensive documentation on the whole process to pre-populate the email address in unsubscribe page. What is a token? How does that prefill the email in an input?  

[SanfordWhiteman]

Form Pre-Fill is here in the product docs.

Tokens are fundamental building blocks of Marketo LPs, emails, and flows, introduced here.

If you’re sending people to an LP from a tracked link in a Marketo email, you do not need to include the Email field on the form itself (as a user-editable input) because the form submission will typically be done on behalf of the person who received the email. It’s still a fine idea to include it to catch some edge cases. But you could also include the {{lead.Email Address}} token somewhere outside the form in a Rich Text area.

Thanks Sanford Whiteman, If we can manage to add the email address in the unsubscribe page url, is it possible then?

Yes, if you did it that way it would force only the email recipient/clicker's email to be used.

Thanks Sanford Whiteman‌. I will try to implement in this way..

Blocking fields means it will not allow to update the field value and I don't think that will help.. Thanks for suggestion..
