Should the user have to click a button after an opening email confirmation link?

When confirming an email address, it is common to send an email containing a single-use link that, once clicked, will mark the email address as confirmed. Some email servers/anti-spam measures will open links in emails, which would falsely show the email address as confirmed.

I have seen cases where, after clicking on the link in the email, the user must click a link/button on the page they are taken to by the email. I assume this is intended to mitigate the effects of the "non-human" clicks by requiring an action that the anti-spam measures would not perform.

Is this a good way to the false positives from such anti-spam measures? If not, how should these false-positives be handled?
