I am looking to send woocommerce emails

Hi
Sorry for posting here. I found some hard to understand blogs on the mailjet website that didn’t answer my question and I am quite technical and have a years experience using wordpress. I have a few questions it would be good to help me understand. I host with siteground and emails just always seem to go into spam of the recipient. For this reason I am looking at a professional email company and have a mailjet account already.

There are no smtp settings in the wordpress settings area as hinted in the post on the mailjet site. Do I need to install the plugin to get to insert my SMTP information.

I am trying to send all my website emails via mailjet will this plugin help to do that.

Thank you.
