What was unclear
The idea started as a broad question: how do you make outreach scale without turning it into spam or flattening every message into the same template? The sending rules, approval flow, and reply experience were not defined for me.

The problem
Mass email tools burn your domain and read like templates, while writing every message by hand does not scale past a handful of people.
The approach
- 01Connected sending to the user's own Gmail account so mail goes out from their inbox, with their own reputation and voice.
- 02Built an AI layer that rewrites one base message for each recipient instead of merging a name into a template.
- 03Put an approval step in front of every send, so nothing leaves unread.
- 04Added sending controls: rate limits, daily caps, send windows, suppression list and unsubscribe handling.
- 05Wired reply tracking so responses land back in the Fanout inbox for follow-up.

What I figured out
I broke the problem into trust, personalization, and control. I worked out how Gmail connection, recipient context, AI rewriting, approval, sending limits, suppression, and replies needed to fit into one safe workflow.

What I delivered
A working fullstack product that takes one draft through personalized review and controlled delivery from the user's own Gmail account, with the account and reply systems around it.
The result
Four steps from draft to sent: connect Gmail, write, personalize, approve and send.
Personal-feeling outreach at volume without the spam mechanics.
