The work goes out. The feedback comes back in pieces.

Project tools hold the timeline. They do not reconcile four people replying to three different versions of the same deck.

We discussed internally. Route B is close but the tone is off and legal has questions. Can you turn something around by Friday?

How long a freelancer waits before chasing you publicly.

Short version

Pidgy is the strongest pick when the bottleneck is client correspondence rather than project tracking. It layers onto Outlook and Gmail, drafts in the account director's own voice and keeps approvals from scattering. Teamwork and Monday.com still own timelines, resourcing and utilisation. Most agencies run a project tool plus an inbox layer.

The shortlist

Scored on inbox fit only. Resourcing, timesheets and campaign delivery sit outside this guide, and several tools below lead those categories.

01 Cabinet pick

Pidgy

Assistant to Ava, account director

It reads what came in, drafts the reply in the account director's voice, and keeps chasing the approval that is holding a print deadline. Nothing leaves the mailbox until a human presses send.

01

Feedback rounds

Four replies on three versions turned into one clear response with the decisions pulled out.

02

Approval chasing

Sign-offs, legal checks and artwork deadlines tracked, with the chaser already written.

03

Awkward mails

Scope creep and overdue invoices drafted in a tone that keeps the account and the boundary.

Inbox fit 10/10
02

Teamwork

Built for client services with good task, time and profitability visibility. Client mail is attached to tasks rather than answered.

Agency project delivery 6/10
03

Monday.com

Flexible, visual and easy to get the whole agency onto, with EU hosting available. Configuration sprawl is the usual cost.

Flexible team workflow 5/10
04

Basecamp

Excellent at pulling client conversation out of email into one calm place, when clients play along. Many will not.

Calm client collaboration 5/10
05

Front

Strong for a shared account mailbox with assignment and internal comments. Account teams work in Front rather than Outlook, which is where adoption stalls.

Shared account mailbox 7/10
06

Superhuman

Fast triage for an account director drowning after a campaign launch. Single user by design, and EU data residency is the constraint.

A single director's speed 6/10
07

Missive

Genuinely good shared inbox with in-thread team chat, popular with smaller agencies. Same tradeoff: it replaces the client rather than layering onto it.

Who each one is for

These are not competing products. They solve different halves of the job.

Choose an inbox layer if

  • Feedback and approvals are what actually delay work
  • Account teams live in Outlook or Gmail
  • Clients reply to old threads and old versions
  • EU hosting and no auto-sending are non-negotiable

Choose a project tool if

  • You need timelines, resourcing and utilisation
  • Profitability per client has to be visible
  • Creative workflow needs structured review stages
  • You are ready for a rollout, not a same-day connect

Questions, answered

What is the best email software for an advertising agency?

Pidgy, if client correspondence is the constraint. It layers onto Outlook or Gmail and drafts feedback responses, approval chases and the awkward scope mail in the account director's own voice. If you need timelines and resourcing, use Teamwork or Monday.com and add an inbox layer on top.

Does an agency need both a project tool and an inbox tool?

Usually yes. The project tool holds timelines, tasks and profitability. The inbox layer handles the client conversation, which is where approvals stall and scope quietly expands.

Can it consolidate feedback from several stakeholders?

It drafts a single response that pulls the decisions out of scattered replies, and an account director checks it before it goes. Consolidating feedback is a judgement call, so a human stays in the loop.

Is client data safe under GDPR?

It depends where data is processed. Agency mail carries unreleased campaign work, pricing and sometimes consumer data, so EU residency and a clear no-training commitment matter. Pidgy is EU-hosted and never trains on your email.
