I already text tenants. Why use this?

Texts and WhatsApp groups work until they don't. Messages get buried in your personal phone, you can't tell which property a thread was about, and every tenant now has your mobile number. August keeps each conversation in one place, linked to the property and any maintenance issue, so the context is always there when you open it. Your number stays private because messages go through the app, not your handset. And tenants who prefer email or SMS still reach you without you switching tools. For a self-managing landlord with several tenancies, that's the difference between a clear thread and a phone full of half-remembered chats.
