Overlay / Postmark
Keep Postmark for transactional. Unify everything else.
Postmark is excellent at transactional mail and deliberately narrow. The moment you send anything else, you are running a second provider with no shared view. Egressif sits on top, keeps Postmark where it shines, and consolidates the rest.
The gap
Where Postmark’s focus leaves gaps.
- ▸ Postmark is great at transactional, and not meant for your other streams.
- ▸ You end up running a second provider for marketing or bulk, with no unified view.
- ▸ Routing and reputation decisions stay inside Postmark’s model, not yours.
- ▸ Message retention and evidence are bounded by their windows, not your audits.
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 Postmark
What stays. What changes.
Postmark stays as the routed path for your transactional stream. We bring the other streams under the same operating layer, give you one consolidated view across all of them, and retain delivery evidence on your terms.
Two ways to work with us
Overlay today, whole stack later. Both work.
Start as a layer above Postmark. 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 Postmark? Answered.
Why not just use Postmark for everything?
Postmark is intentionally focused on transactional and discourages bulk or marketing. Rather than fight that, we keep Postmark for what it is best at and operate your other streams alongside it under one layer.
Do we keep Postmark’s deliverability?
Yes. Postmark stays a routed path. We add cross-stream monitoring, route engineering, failover, and evidence that is not bounded by a single provider’s retention window.
Can we see transactional and marketing together?
That is the point of the overlay: one consolidated view of every stream and path, instead of one dashboard in Postmark and another somewhere else.
