Generate the Opt-in link manually without sending email from template in MailManager4Act
Using the menu option MailManager4Act > Optin Management > Send Emails command, your Contacts will be sent a unique link which they can use to submit their Opt-in/Opt-out requests. If for some reason, you wish to generate a link for the Contact without sending them an email using the process above, click the menu MailManager4Act > Optin Management > Generate Unique Link
This will copy the unique link to your clipboard for the current Contact that is in your detail view.
You can now paste this link in a separate email and send it to your Contact directly. This feature is useful if there was an issue with the original Opt-in email and the Contact was unable to submit their request.
