Verification link in email

Could anybody write me why verification link in email is clickable only after 10-15 seconds?

What do you mean by your "verification link"? Please explain what you are trying to do and whether you are attempting to reply to or use a link from an email that was sent to you.

Often emails asking you to verify information are phishing and links will send you to phony sites designed to harvest your personal info. Best not to reply until you know the source.
