Email is one of the most important parts of your product. And one of the least visible.
A user signs up. A password reset is requested. An order is placed. Behind each of these moments is an email that has to arrive on time, in the right inbox.
But when something goes wrong, most teams end up asking the same questions:
❓ Was the email even triggered?
❓ Did it get sent?
❓ Did it reach the inbox?
❓ Did the user open it?
If the answer is “we’re not sure,” that’s a black box. And black boxes are painful to debug.
That’s why we built MailCub around a flow you can actually follow:
🔌 Integrate: connect MailCub to your existing stack
⚡ Trigger: fire emails from the events in your app
📤 Send: dispatch them through a clean, developer-friendly workflow
📬 Deliver: get your messages to the inbox
📊 Track: see what happened, so you’re never guessing
The goal is simple: email that feels like part of your stack, not a service you have to work around.
If you’re a developer, a startup founder, or a team building a product that depends on email, we’d love for you to try it.
