Why sign in with Google or Microsoft?
SmartFlowPros sends from your own inbox — so replies come back to you and your deliverability stays high — and it watches for replies to stop follow-ups automatically. That’s what it connects to. You sign in at Google/Microsoft, so we never see your password. Access is used only to send your sequences and detect replies — never your calendar, contacts, or files — and you can revoke it anytime.
You’ll be asked to allow sending and reply detection — keep both checked so everything works. Approve and you’re in: trial active, no card.
On an iPhone, or Microsoft asking for the Authenticator app?
If Microsoft asks you to verify with the Authenticator app, open the “Authenticator” tab at the bottom-left of the app — not “Verified IDs.”
Don’t want to use the app? On the Microsoft sign-in screen, tap “I can’t use my Microsoft Authenticator app right now” → “Text a code” to get a code by SMS instead.
Still stuck? Start with your email below — you can connect Microsoft later.
Want to look around first? Start with your email — you’ll connect your inbox later, when you send your first sequence.
