user not getting all campaigns

[CanCard]

I have a Staff member that is not receiving all the campaigns.  The lists for Staff is always added as part of the Lists. All the other staff are getting the emails. 

He shows up in the Staff list, his account shows Implied consent.  We have changed to Express to see if that makes a difference.

For example, he received newsletters on May 13, 21, 23, 26 but didn't receive the one sent May 27.  

Any insight would be appreciated.

Hello @CanCard ,

Here are some general best practices for delivery.

Delivery can have a lot of variables, from elements on our side, on your side, on the recipient's side, and in their email system company's side. It's typically best to set up additional authentication for your emails, such as self-authentication if you have your own domain.

If you'd like to learn more about safelisting, and what it entails:

Safelisting domains in a security system

Safelisting email addresses in an email client or security system

If you're wanting more in-depth, specialized insight on your current deliverability, it'd be worth speaking with one of our Delivery agents.
