What do you mean by if their email is still active ? What is the difference between an inactive and an active email address?

Is it that the server accepts the email address? Is it that the email gets delivered to a mailbox? Is it that a person reads the email? Is it that a person wants the email?

Ask yourself and ask your boss about that.

Short of sending out an email and getting a confirmation email, there is no way to determine that a person still sits behind the email address you got and wants to receive your emails. Consider offering discount tickets via your email, or some raffle or whatever to make people (re)subscribe.

Also note that many spam filters directly delete emails that contain links to images outside the email, so you will be throwing out the child with the bathwater if you try that route.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
