Be honest: there’s nothing worse than staring at an empty inbox waiting for a critical email to arrive.

When your app’s user experience relies on transactional emails, a single delay can cause user frustration, dropped carts, or support tickets.

Which one do you fear missing the most?

A – OTP / Verification codes (The ultimate user-flow killer)

B – Password resets (When you're already locked out)

C – Payment confirmations (Did it go through? Did I get double-charged?)

D – Security alerts (Immediate panic mode)

Payment fails ➡️ Email is triggered instantly.

The user receives the notification without delay.

The user retries their payment.

Your revenue is successfully recovered.

Stop letting a "250 OK" status hide your poor inbox placement.

When a receiving server accepts an email, it's simply acknowledging receipt. What happens next inside their internal spam filters is a black box for most SaaS teams.

MailCub cracks the box open. Instead of stopping at the server gate, MailCub tracks the actual Placement Insight:

Inbox: 92%

Promotions: 5%

Spam: 2%

Blocked: 1%

Know exactly where your transactional and marketing emails land so you can optimize your sender reputation before it hurts your onboarding metrics.

Is your email delivery killing your user experience? 📉

In product development, we obsess over page load speeds and API latency, but we often overlook the most critical touchpoint: the inbox.

When a user requests an OTP or a password reset, the clock starts.

3 seconds: They start to doubt your service.

10 seconds: They’re checking the spam folder (and seeing your competitors).

30 seconds: They’ve moved on.

At MailCub, we believe "eventually" isn't good enough. Our infrastructure is built for millisecond delivery, ensuring your users stay in your app, not their inbox.

⚡ Stop the churn. Fix your delivery speed with MailCub.
