Pet Symptom Checker alternatives

I might have used this. The description sounds great. However, the way i learned about it was an email from a vet i used a year ago from a moved away from that state a year ago. Instead of giving an option to unsubscribe as i have a local 24 hr vet that i trust, the email says to login and to change my preferences. Since I don't have an account, I'm certainly not going to create one in order to unsubscribe to it.... I just blocked and reported as spam instead. Maybe there is a way not listed on the email, but I don't think that is worth the effort to find out. I don't actually even remember asking the vet i saw one time before flying with my cat in order to move to send me emails in the first place. Could be wrong about that but it wouldn't make much sense. Either way, not fond of how this email was set up or how i received it, so I'll stick with my local vet for now. Thanks.
