Valid Spam - white list an email

[ChrisH3]

Cozi Calendar emails go into my spam (no-reply@cozi.com) and I can not seem to stop it.  I tried a rule, create a contact and keep saying it is not spam.  Is there a white list feature to say this is valid?  I don't want to use the feature that I have to list every valid email but rather add one's that Comcast filters say are spam.

@ChrisH3 There currently isn't a "whitelist" system in place and emails in spam cannot be filtered with user created filters unfortunately. I have processed a clear for the spam filtration and should take effect within an hour.
