When I inspected your recipient addresses, I found that they are on our bounce list. You can also check them by yourself:
What does "bounce list" mean?
Our servers will try several times to deliver the messages for a given time-frame, but if the delivery constantly fails, it will mark it as "old", "rejected" or similar, and it will store your recipient email address in our bounce list.
I removed all of your recipient addresses from our bounce list. You can see the bounce reasons from the screenshots.
In order to prevent the bounce issues, I'd like to recommend you to review our user guides:
If your problem persists, please let us know.
