An agency inbox that drafts the reply for you
The Proofsource agency inbox collects every pitch, reply and client conversation in one place. When a prospect answers, a reply is drafted with an invite from your own calendar, ready to send. Day 3 and day 7 follow-ups are planned for every pitch, each thread has an owner, and every email shows its delivery timeline. Counts on the menu show what is waiting.
| Thread | Owner | Delivered | Opened | Replied |
|---|---|---|---|---|
| Driffle in ChatGPT answers | Priya | Yes | Yes | Yes |
| Lumen Labs and Fathom | Sam | Yes | Yes | No |
| Kite Notes in AI Overviews | Sam | Yes | No | No |

What is an agency inbox with AI-drafted replies?
An agency inbox is a shared mailbox view for the people an agency is pitching and serving. The hard part of outreach is rarely the first email. It is answering quickly when someone replies, following up on time when they do not, and making sure two people do not answer the same thread.
AI-drafted replies help when the draft is grounded in facts the agency already has. A reply to 'Can you show me more?' should offer a time and point at the prospect's own answers, not a generic paragraph.
Proofsource drafts each reply from the pitch and its scan, with an invite from the member's own calendar attached. Follow-ups on day 3 and day 7 are drafted and scheduled, and you can edit, redraft, send now or skip each one. Threads have owners, every email has a delivery timeline, and the inbox shows counts for replies and approvals waiting. When a booked call is close, a call brief appears.

Questions about agency inbox
What is an agency inbox in Proofsource?
It is one view of every pitch, reply, follow-up and client conversation your agency sends through Proofsource, with drafted replies, owners and delivery timelines.
How are replies drafted?
From the pitch and the prospect's scan, so the reply refers to their real answers. Each draft is yours to edit, redraft or send.
Which calendars can I connect?
Each member can link their own Google Calendar or Cal.com, and invites are sent through it.
When do follow-ups go out?
On day 3 and day 7 after a pitch, unless the prospect replies or you skip them. You can edit, redraft or send each one now.
What happens if I run out of credits?
Follow-ups that need credits wait, and an Add credits banner shows. They never fail silently.
Can two people work the same inbox?
Yes. Assign an owner to each conversation so the right person answers.
Is there a brief before a booked call?
Yes. When a booked call is close, a call brief appears with what the prospect read, their worry, their goal, what to show and one ask.
