Aggregation done right: orchestration, not resale.
Most teams sending serious volume already pay two or three ESPs. Each ESP has its own dashboard, API, webhook format, and quota model. Operating across them means switching tabs, writing glue code, and reconciling numbers by hand.
Mailers.io aggregates those providers into one control plane. Unified routing, unified reporting, unified audit trail. You keep your provider contracts and your provider reputation. We give your team one surface to work from.
From many dashboards to one.
- Step 1
Attach providers
Connect every ESP and SMTP server you use today. Each becomes a sending server with its own quota and priority.
- Step 2
Route and send
Use the unified API or the dashboard. Quotas, priority, and failover decide which provider sends what.
- Step 3
Report and reconcile
One dashboard for delivery, bounces, and complaints across every provider, with provider attribution on every event.
What aggregation should give you, done properly.
Provider-agnostic API
One endpoint, every provider. Switch providers without rewriting integration code.
Quota-aware routing
Per-hour and per-day limits enforced at the platform layer, regardless of provider-native limits.
Automatic failover
If one provider errors, the next pool member takes over — no manual intervention.
Unified reporting
Delivery, bounces, complaints, and opens rolled up across providers with attribution per event.
BYOP billing
Your ESP bills stay with your ESPs. No resale margin. No lock-in.
Per-workspace isolation
Agencies and platforms can aggregate providers per client workspace, with zero bleed between them.
Suppression across providers
Unsubscribe and DNC enforced before every send, no matter which provider handles it.
Cross-provider audit trail
Every send, every event, every config change — recorded centrally for compliance.
- You run email across 2+ ESPs or SMTP servers
- You want one operational surface instead of several vendor dashboards
- You want to keep provider contracts direct (no resale)
- You need consolidated reporting across the whole stack
- Aggregation is routing + reporting, not reputation merging
- Each provider still has its own policies and limits; we respect them
- Analytics stay per-provider accurate; we do not fabricate cross-provider metrics
Questions answered clearly.
Consolidate every provider. Keep every contract.
One dashboard, one API, one audit trail — across every ESP and SMTP server you already run.
