GOMAILER
Your app doesn't need another project inside.
Get a tried-and-tested email system, ready to use. Install it once and get back to your own work.
- You save hours of development
- Failures stop being one more thing to maintain
- Install it once and carry on with your app
You get it finishedIt's yours forever
All of this is already done.
It's what sits behind a simple “send email”. You don't have to write or maintain any of these pieces.
- Sending queueHandles thousands of emails at once.
- Sending paceAt the speed your provider can take.
- Smart retriesIf the mailbox is full, it keeps trying. If it doesn't exist, it stops.
- No duplicatesEven if the server restarts halfway through.
- One-click unsubscribeThe kind Gmail and Yahoo require.
- Bounces and complaintsThose addresses get set aside automatically.
- Alerts to your systemWhen an email goes out, bounces or unsubscribes.
- A dashboard to see it allNo digging through logs.
Without GoMailer
Your work
- You build yet another system.
- You have more code to review.
- Every failure ends up back with you.
- And months later you still have to maintain it.
Your emails
- Sending to your whole list at once can get you blocked.
- Gmail and Yahoo require an unsubscribe button that you have to code.
- Every bounce stains your domain a little more.
- The more your list grows, the more you pay.
With GoMailer
Your work
- You install it once.
- Sending manages itself.
- You know what's happening whenever you want to look.
- And you go back to building your app.
Your emails
- You send to thousands of people, at the right pace.
- The unsubscribe button they require comes built in.
- Bounces get blocked automatically.
- You pay once and your list can grow as much as it likes.
Less code to maintain. More time for your product. And emails that comply from the first send.
You tell it what you want to send. GoMailer takes care of the rest.
Sends without overloading
Emails go out at the right pace.
If something fails, it tries again
Without you having to step in.
Remembers who unsubscribed
So it never emails them again.
Shows you what's happening
So you don't have to hunt through logs.
Underneath, it does the technical work. You don't have to build it.

You don't have to imagine how it will work. You can watch it working.
You launch the send and GoMailer starts sending the emails, retries the ones that fail and honors unsubscribes.
You can see everything. But you don't have to keep watch over everything.
And if you work with AI, you don't even need to open the dashboard.
Ask it from Claude, ChatGPT, Gemini or Cursor.
Fewer screens to check. Fewer things interrupting your work.
Your emails get delivered, follow the rules and don't cost you more as you grow.
Everything your app needs to send emails, we give you built.
And you can even resell it.
