Sending one email to each interviewer or both in one email?

I just had an interview with an analyst and a more senior member to the team (at the same time). In all our previous emails, like the Teams invitation both of them were always cc'd. So would it be okay to simply send one thank you email including both of them? 

Is it appropriate to just start the email with for example:

Dear John and Alex,

xxxxxxx

Best regards,
