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:
- Create an account
- Use all free trial credits
- Register again
- 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.
