It’s a Friday evening, and your biggest sale of the quarter is live. Campaigns have gone out on schedule, traffic is climbing, and orders are coming in. Everything is going exactly as planned.
Until it isn’t.
Customers suddenly stop receiving OTPs. Order confirmations are delayed. Support tickets start piling up.
Your application is running fine. Your campaigns are ready. But your email service provider (ESP) has slowed down, and your emails are stuck waiting.
You have a backup provider, but switching to it isn’t straightforward. And with customers waiting, every minute matters.
An ESP outage shouldn’t be the moment you discover your backup isn’t ready.
But outages aren’t the only challenge. What if you’ve found a better email provider, but moving to it means risking the email infrastructure you’ve already built?
These are the two challenges we built Netcore Orbit to solve.
Challenges Holding Email Programs Back
1. When your ESP goes down, your emails shouldn’t
Businesses rely on email for everything from OTPs and transaction alerts to order confirmations and marketing campaigns.
When your email provider experiences an outage or slowdown, the impact goes beyond delayed messages. Customers are left waiting, transactions are interrupted, and important business communications come to a standstill.
Many businesses have a secondary ESP, but a backup that hasn’t been integrated, tested, or prepared to handle live traffic isn’t much of a backup.
Your business needs email infrastructure that can keep moving, even when one provider can’t.
2. Moving to a better ESP shouldn’t mean one risky switch
Switching email providers is rarely a simple decision.
Even when another provider offers better performance, visibility, or support, the effort and risk involved in migration can hold businesses back.
There are integrations to change, sending reputations to protect, and large volumes of email traffic to transition.
And perhaps the biggest concern: How do you know a new provider will perform better before moving all your traffic?
So businesses often stay with their existing ESP, not necessarily because it’s the best choice, but because switching feels too complicated.
What if you could try a new provider with your actual email traffic, compare performance, and move only when you’re confident?
Introducing Netcore Orbit
One API. Multiple ESPs. Complete routing control.
Orbit is a low code, centralized email routing layer that gives businesses the flexibility to manage multiple email service providers through one integration.
Instead of depending on a single ESP, businesses can distribute traffic across providers, maintain a ready backup, and automatically reroute emails when delivery slows or a provider becomes unavailable.
And when it’s time to move to a better ESP, Orbit makes it possible to transition gradually, without a disruptive, all-at-once migration.
One integration. More flexibility. Greater control over your email infrastructure.

Orbit is built around five principles:
- O – Operational Resilience: Keep an alternate email route ready.
- R – Routing Control: Decide how email traffic is distributed across providers.
- B – Best-Route Intelligence: Make routing decisions using provider performance signals.
- I – Integration Simplicity: Connect to multiple ESPs through one API, with minimal application changes.
- T – Transition Without Disruption: Move email traffic progressively, without a big-bang migration.
What Can You Do With Orbit?
1. Keep your emails moving with automatic failover
An ESP outage shouldn’t bring your business communications to a halt.
With Orbit, businesses can configure automatic failover to redirect email traffic to another available provider when delivery slows or the primary ESP becomes unavailable.
Rather than scrambling to switch providers during an outage, you have an alternate route already integrated and ready.
This means fewer disruptions to critical communications and less dependency on any single provider.

2. Distribute email traffic across multiple ESPs
Why depend entirely on one provider when you can use multiple?
Orbit lets businesses decide how to distribute email traffic across different ESPs, whether that’s splitting traffic between providers or routing specific types of communication through different services.
For example, you could send transaction alerts through one provider and marketing emails through another, while managing everything centrally.
And as your business needs change, you can adjust your routing strategy without rebuilding your integrations.
3. Get one view of your email traffic
Managing multiple ESPs often means switching between different dashboards to understand what’s happening.
Orbit brings visibility into your email traffic across providers into one place.
Monitor delivery performance, track how traffic is distributed, and identify potential issues before they turn into bigger disruptions.
More visibility means more informed decisions about where and how your emails are sent.
4. Try Netcore Email API on a Small Share of Your Traffic First
Switching email providers shouldn’t mean moving everything overnight.
With Orbit, you can introduce Netcore Email API gradually while your existing ESP continues handling the rest of your traffic.
Start small. Test performance with real traffic. Compare results. And increase the share of emails routed through Netcore as your confidence grows.

Your existing provider can remain available as a backup throughout the transition.
And there’s no requirement to move everything. You can continue operating with multiple ESPs if that’s what works best for your business.
With Orbit, migration becomes a decision you can make with confidence, not a risk you have to take all at once.

Orbit makes the transition easier. Netcore Email API gives businesses a powerful email delivery platform to move to.
Built for high-volume, business-critical email, Netcore Email API combines scalable infrastructure, AI-powered delivery intelligence, and visibility into email performance.

You can start by routing a portion of your existing traffic through Netcore Email API, evaluate performance in your own environment, and decide how quickly you want to move.
The opportunity to improve your email infrastructure shouldn’t come with the risk of disrupting it.
