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.

How it works

One inbox for every prospect and client conversation, with AI-drafted replies, calendar invites, day 3 and day 7 follow-ups and an owner per thread.

  1. Pitch goes out

    Sent pitches land in the inbox with a delivery timeline.

  2. Follow-ups are planned

    Day 3 and day 7 follow-ups are drafted and scheduled, with settings you control.

  3. A reply comes in

    The thread fills in and a reply is drafted with an invite from your calendar.

  4. Assign an owner

    One person owns each conversation, so nobody answers twice.

  5. Send answer and invite

    The main button sends the drafted reply with the invite.

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.

Proofsource is live: scan your brand and see agency inbox at work with your own answers, competitors and sources.
