Hi Unbounce,
as unbounce is a tool that allow us to do A/B split test, and there are many optimization specialist/agencies out there who does a great job too. Many of them are familiar with Unbounce as well.
BUT it won’t be convenient to add them into our own sub-accounts, as there might be campaigns that are confidential.
And if we have to pay for the same custom domain again, in order for them to do we will have to pay again, which I think its not really fair since we already paid for them. I would not mind paying more for custom domains, but IMO i think it should be available throughout the sub-accounts. Just my thoughts. Hope you guys can do it 🙂
