Email Campaigns Failing

We are in real estate and each month send out videos to both past and current clients. This month, I tried to send our Valentine’s video and it failed to our contacts. Tried reaching out to help desk and nobody responded. We are having severe struggles when it comes to sending videos each month and thinking that maybe this platform isn’t right for us as we are sending batch emails. BTW, we use outlook for emailing. Is anyone else having these struggles? Anyone know how to fix this problem?

I also just sent out a batch email using the email campaign tab. I have a few opens however It appears that I have received only a couple of video views. I also get a location from Texas whenever I click on my video to preview it prior to sending it.
