This is a work related question – we regularly send bulk emails to opt-in clients, but our web guy that normally handles this is out today. If I try to send an email to a huge list of people (in the double-digit thousands) is it going to go through? I have no special program to do this – just Microsoft Outlook. Any advice would be very helpful. We have some super exciting news about our company and want to spread the word!
It’s NOT SPAM!!!! Like I said – these are opt-in clients, meaning they all agreed/signed up to get emails from us.

Thanks
