Hello @SafeHouseBlackHistoryMuseumB4 ,
You'll just need to make sure any emails you utilize for your From or Reply-To address are verified on your account. You'd just update the header of your email while editing it, or on the scheduling page, when you need to change who the email campaign is coming from.
If you're sending using your own unique domain (as opposed to a free one like Gmail, Yahoo, etc.), then I'd also advise setting up your account for self-authentication to ensure the best delivery rates.
If you need guidance on adding and managing users to your account, please see this article.
