Why is Comcast blocking emails from 1-800-PetMeds.com?
My pet supply vendor 1-800-PetMeds informed me that Comcast started blocking their emails. Why is that? I use them all the time for online orders and now I can't get order confirmations, customer support, or anything from them. Their email address is CustomerService@1800petmeds.com
Would you fix this please? Thank you.
