Overlay / Mailgun
Keep Mailgun’s API. Add the operations team it isn’t.
Mailgun is a capable developer API, and an API is all it is. Deliverability, reputation, and incident response still land on your engineers. Egressif sits on top of Mailgun and supplies the operations layer the API does not.
The gap
Where Mailgun stops and your engineers start.
- ▸ Mailgun gives you an API, not an operations team.
- ▸ Deliverability and reputation management still land on your engineers.
- ▸ When a send degrades, you are reading logs, not getting a heads-up.
- ▸ A single provider is a single point of failure with no built-in fallback.
How the overlay works
Your ESP becomes one path. We become the layer above it.
What the layer adds
What you gain on top of moving mail.
Monitoring on the wire
We watch the actual responses your sends get from receivers, in real time, across every path. Blocklistings, reputation signals, deferral waves, and auth failures get caught as they happen, not in a weekly export.
Ordered failover
Your providers and our network become ordered paths. When one is blocked or throttled, traffic moves to the next automatically. A single provider having a bad day stops being your outage.
Route engineering
Decide how mail leaves: which path per destination, priority for time-sensitive messages, per-receiver throttles, separate lanes per stream. Routing becomes something you configure, not something a single vendor decides for you.
Suppression at the gate
Bounces, complaints, and do-not-contact requests are enforced beneath every application and every path, so an upstream mistake cannot send to someone who already opted out.
Evidence per message
For every message: which server accepted it, when, over what TLS, with the verbatim response, retained on your terms rather than expiring in a provider’s short window.
One provider for the whole stack
DNS, mailboxes, and sending under one operator instead of a different vendor for each layer. Fewer seams, and one team accountable when something breaks instead of a finger-pointing call.
Consolidated view
Every stream and every path in one place: what sent, what landed, what is at risk. Stop stitching together a separate dashboard per vendor to answer one question.
One vendor, one bill, one API
A single relationship, a single invoice, and one API for provisioning and delivery events, instead of integrating, reconciling, and paying several.
No migration
You keep your provider, your templates, and your code. Point your sending at us and your current setup keeps carrying traffic until you are satisfied.
Stream separation
Transactional and marketing stop sharing a reputation. Each stream earns its own, so a campaign can never sink a password reset.
Keep Mailgun
What stays. What changes.
Your Mailgun integration stays and becomes one routed path under the operating layer. We add the monitoring, failover, suppression, and evidence around it, so your engineers ship features instead of babysitting deliverability.
Two ways to work with us
Overlay today, whole stack later. Both work.
Start as a layer above Mailgun. If you ever want us to own DNS, mailboxes, and the network too, the path is already there.
Managed
We run it for you.
Routing, suppression, warming, reputation, and incident response are ours. You get plain-language reporting on what happened and what we did. The email part of your week goes quiet.
Self-serve
You drive it.
Provision domains and mailboxes, set routing and fallbacks, and pull delivery data through the console and API. The same engine, operated by your team, at your pace.
FAQ
Running Mailgun? Answered.
Do we change our Mailgun code?
No. Mailgun stays as a routed path and your integration is untouched. You point sending at our relay or API when you are ready, and Mailgun keeps carrying traffic in the meantime.
What does the layer add over Mailgun’s analytics?
Mailgun shows you logs after the fact. We operate in real time across paths: rerouting around problems, enforcing suppression beneath your app, and alerting a human when something degrades.
Can Mailgun be our fallback, not our primary?
Yes. Routing is yours to configure: Mailgun can be the primary path, a fallback, or one lane among several.
