For those of us who offer direct outreach ( for clients, podcasts, affiliates, sponsorships etc), for multiple brands, how are you preserving url health?

Are you buying a new url for each campaign/client/brand?

I am asking because in working with outsourced sales, the routine is to get a fresh url and do outreach from the new url.

What is your process for running multiple outreach campaigns at once besides having your client use their url?
