Agencies running outbound for many clients typically end up paying per-seat for deliverability tools. That doesn't scale below 10 clients, and hurts above 30. Inbox Check's free tier is designed around multi-client workflows without a per-seat model.
Agency features on the free tier
- Tag placement tests by client.
- Per-client dashboards and exports.
- Monitor up to 10 domains per account (more on request).
- Webhooks for alert routing into client-specific Slack/Teams channels.
- API for scripted weekly-review reports per client.
- Branded-export option for client-facing reports (paid add-on).
Typical agency workflow
- Onboard a new client: add their domain to monitoring, run a first placement test for baseline.
- Weekly: cron the API to re-test every client's current template; digest goes to each client's Slack.
- On alert: pause the affected client's sequence, investigate via per-seed detail.
- Monthly: export per-client report with auth verdicts + placement trend for billing-attached deliverability reports.
Capacity that fits agency scale
- 100K+ tests/day — enough to re-test every template for 200+ clients weekly.
- Rate limits are per-email and per-IP, not per-account, so clients with their own domains share nothing but the aggregate network.
- Paid tier available when you need priority queueing or > 90-day retention.

FAQ
Can I white-label the reports?
Branded-export add-on on paid tier. The URL, colors, and logo on the export get replaced with yours.
Do my clients see each other's data?
No. Tag isolation and role-based access separate them.
What's the cheapest way to use this at 20+ clients?
The free tier, honestly. Most agencies never bump into a paid need. If you do, the paid plan is cheap relative to the per-seat pricing of alternatives.
