Issue with Email Address in a form (Unsubscribe)

[Manish_Khemani1]

Hello Marketo Experts

Before I explain the issue Let me highlight the steps I am executing:
1. On a landing page I fill out a (Marketo) form with email address 1 and I receive an email confirming the same which has the 'Global Unsubscribe link' pointing to http://info.tcs.com/NewsletterUnsubscribe.html on email address 1
2. Now, from the same workstation & from the same landing page again, I fill up the form with email address 2 and accordingly receive the email on email address 2
3. I click on the Unsubscribe link from email I received on email address 1 and it pops-up email address 2, instead of email address 1.
Is there a way I can show the email address 1 if I click on the Unsubscribe from email of email address 1 & vice-versa?
