Four brands collecting emails together.

Four brands are heading to a state fair and we are collecting emails under one “generic name” (the name of the bar we are creating together). I use Klaviyo but not sure what other brands use for email marketing. What are my options so that people are subscribe immediately to my Klaviyo email list so that I don’t have to transfer the list and start to opt in process again? Could I use my own Klaviyo account to collect all emails? Yes, correct? But the email subscription will come from my email account name, which might be confusing to people. Any ideas? I guess I can have the first part of the email be the name of the bar. I hope this make sense.
