How my AI Video app became profitable after blocking disposable emails

I’m a startup founder building an AI-powered video generation product.

Like many SaaS companies, I launched with a simple growth strategy:

  • a free trial
  • trial credits for new users
  • subscriptions for long-term customers

At first, everything looked great. Sign-ups were growing, users were generating videos, and subscriptions started coming in. But very quickly, I ran into a serious problem.

Trial Users Were Draining My Resources

Every new account received free credits to generate videos. AI video generation is expensive:

  • API costs
  • Storage

After a few weeks, my infrastructure costs started exploding. At first, I assumed this was normal growth. But the numbers didn’t add up:

  • sign-ups were increasing
  • costs were increasing even faster
  • revenue was not catching up

The business was heading toward losses.

The real issue: abuse and fake accounts

After investigating, I discovered the truth: These weren’t real users. They were abusers creating unlimited free accounts. The pattern was always the same:

  1. Create an account
  2. Use all free trial credits
  3. Register again
  4. Repeat endlessly

And the key detail: Most of them were signing up with disposable temporary email addresses.

My startup was losing money

This abuse created a dangerous situation: I was paying for video generation, while abusers were consuming resources for free. The result:

  • Trial credits became a financial leak
  • Infrastructure costs skyrocketed
  • The product became unprofitable

Without solving this, the business couldn’t scale.

The Solution: Verify Email API

To stop the abuse, I needed to block disposable email registrations. That’s when I integrated the Verify Email API. Verify Email helps detect:

  • Disposable or temporary emails
  • Invalid emails

Now, every time a user signs up, I verify the email instantly.

How It Works

The signup flow became simple:

  • If the email is disposable → block registration
  • If the email is real → allow trial access

Abusers were stopped at the door.

Results After Blocking Disposable Emails

After integrating Verify Email:

  • Fake trial sign-ups dropped dramatically
  • Infrastructure costs went down
  • Trial abuse was eliminated
  • Subscriptions finally covered expenses
  • The business became profitable

This one change protected my entire product.

Final takeaway

If your SaaS offers:

  • Free trials
  • Free credits
  • Freemium access

then disposable email abuse is a real threat. Blocking temporary emails is one of the fastest ways to reduce costs and protect revenue.
