Mautic Pulgin development for email validation

Hi,
I am developing a plugin to integrate email validation in mautic.
So whenever any campaign is been trigger that has send email action we want to identify that the event is fired from campaign and not from contact or from from event.Is there is a way to get info from where the event is been triggred from. We are using EmailValidationEvent.

HI! First of all, welcome to our Mautic Community! :mautibot:

What you are talking about its really interesting. The only issue I do not clearly understand is if you are checking the email before sending, If so, why don’t you think in performing it after double optin?
