Hi! Wondering if anyone here can help shed some light on an issue we are experiencing.

Recently started to use a new set of email templates. All appears good to go when we test through Litmus and when we send our messages to the internal proofing team prior to delivery. The SCL of the messages when the proof/test email is sent is at 1. However, when the email is delivered to our internal team, the message lands in junk and the SCL score changes to 5.

Can anyone point me in the direction of a resource which could help us troubleshoot? We're confused as to why the SCL score is changing from the test send to the actual send.
