Issue with HTTP Status 400 - Bad Request when sending email campaigns

[MarilagM3]

I am writing to bring to your attention an issue I have been experiencing today. I have been unable to send the Zoom link to the participants as I keep receiving an HTTP Status 400 – Bad Request error.

This is a time-sensitive matter, as I need to provide the Zoom link to all the attendees in a timely manner. I would greatly appreciate if you could please look into this problem and provide a resolution as soon as possible.

Thank you in advance for your assistance. I am available should you require any additional information from me.

I have gotten this 400 HTTP error on every email send for the last few weeks... the emails seem to be going out regardless, so I haven't been too worried about it.  I'm not using any APIs, this is directly on the CC website.
