What you are probably seeing
Outbound emails from your personal inbox vanish into the spam folder within days of consistent sending.
Open rates drop to near zero on lists where contacts were imported without confirmation or recent interaction.
Why it happens
Consumer providers flag accounts with high volumes of mail to unverified addresses as suspicious bot activity.
Modern inbox filters penalize generic templates sent to large, cold contact lists with low trust signals.
What changed recently
Step by step
1. Stop using your personal consumer email address for all outbound business communication.
2. Create a separate workspace domain for the team to manage shared calendars and professional identity.
3. Build a sender email on that custom domain to establish distinct trust away from consumer providers.
4. Audit existing contact lists and remove anyone who has not engaged or verified their address.
5. Send initial communications only to small segments of verified, relevant contacts with personalized details.
