Inbox assistant
Ezra vs Superhuman Go for marketing agencies
Superhuman Go works on your inbox and calendar. Ezra works on your client accounts. Agencies often run both, because the jobs do not overlap.
Reviewed August 2026
Ezra
Ezra is an AI system that works inside your agency Slack workspace.
Assign a client review, a report, a pacing check, or a research brief. Ezra gathers the evidence, prepares the work, and sends sensitive changes to a named approver.
Ezra keeps each client account separate, with confirmed goals, KPI definitions, and reporting preferences attached to the person who confirmed them.
Choose Ezra when an agency team needs recurring client account work prepared with evidence and routed for human approval.
- Slack-native
- Multi-client
- Evidence-linked
- Approval-controlled
Superhuman Go
Superhuman Go is an assistant for email and calendar work: triage, drafting, follow ups, and scheduling.
It is strong at keeping personal correspondence moving.
Client performance data, reporting packets, and advertising approvals sit outside that surface.
Choose Superhuman Go for inbox and calendar work.

Two different jobs in one agency day.
An inbox assistant clears correspondence. It does not know whether last week's cost per acquisition beat the client's target.
Ezra prepares the work the client is paying for and returns it where the account team talks.
The client update your inbox assistant helps you send can start from a packet Ezra already prepared and sourced.
