JC,
This is from us, Adventure Pilot. We use the Zoho Support tool for managing our incoming support emails and general "tickets and tasks". It's a support tool like ZenDesk or others that companies use to help streamline, track and manage support/task workflow. All emails are received, read and responded to by AP staff right here in McKinney, TX. Zoho Support is not a support provider, rather just a support ticket management tool.
Typically, the email you receive from it should have a Signature from the support rep or AP staff member. Zoho assigns an "adventurepilot.zohosupport.com" email domain to track and manage these support emails. It's very much helped us manage the "growing pains" as we've matured and allowed us to provide even better customer support with fewer "dropped balls".
Sorry for the confusion, this is not a phishing email, I'll see about adding our URL or some text to each signature, to help eliminate any further confusion. Thanks for your concern and feedback.
