Email experts:

I have an old class list of emails for a reunion
I want to ensure that the addresses are current before sending out a notice for upcoming events
how could I check the servers to see if these emails still exist and to who they are registered?

Thanks

You could try googling the email address too to see if any recent results come up (eg blog sites), but email addresses are commonly kept private so you won't get a good hit rate even for addresses that are still in use.

Not the answers I was hoping for.
I looked around and found that it may be possible to eliminate/confirm a subset of the list through a mufti -step process with the right scripts...
Since this is a friendly undertaking we will simply send out a request to reply and hope that the interested folks check their email regularly.

I'd suggest posting that request as a separate question.

Yeah, the big problem is spammers. If it is possible to verify an email address, then it makes harvesting and compiling lists a LOT easier. In 2016, this would be problematic.
