Right now, when I test an email, I can use any student record, even if that student doesn't match the criteria for the message. For example, if the email is intended for students at the “Enrolled” stage, I can still preview it using a student who is only at the “Inquiry” stage or hasn’t been accepted yet. This makes the test inaccurate and not helpful. My workaround has been to create a test profile for every stage.
However, what I’d like to see is something similar to other marketing or CRMs. When you preview or test an email, it only shows results for students who meet the email's criteria. If you try to use a student who doesn't qualify, it tells you that the message doesn’t apply to them. This makes sure you're constantly testing with the right audience and seeing precisely what they will receive. This is also very helpful when the groups have several filters.
