Tired of spam signups, fake accounts, and free trial abuse? Say hello to MailCheck – your platform’s new gatekeeper against disposable and suspicious emails. 🔒📩
❌ The Problem
Fake emails hurt your platform in real ways:
Abused free trials 🎁
Inflated analytics 📉
Wasted server/API resources 💸
Extra load on customer support 🙄
Skewed user metrics = bad decisions 😤
✅ The Solution: MailCheck
MailCheck offers a real-time email validation API that doesn’t just check the format — it goes deep. It checks:
Domain & MX records
Known disposable email providers
User behavior signals (for high-risk ones)
🧠 How It Works
Two-level smart checks:
🔹 S1 Check (Standard):
✅ Fast, checks domains, MX, and disposable lists
✅ Ideal for sign-up forms
➡️ Returns is_valid + needs_TBA
🔹 TBA Check (Task-Based Authentication):
🧐 Behavioral analysis for risky emails
🐢 Slower but smarter – only runs if flagged by S1
⚙️ Sample Workflow
Run S1 for every signup
If is_valid = true & needs_TBA = false → ✅ Accept
If is_valid = false → ❌ Reject
If needs_TBA = true → 🔍 Run TBA check
Run S1 for every signup
If is_valid = true & needs_TBA = false → ✅ Accept
If is_valid = false → ❌ Reject
If needs_TBA = true → 🔍 Run TBA check
🛠️ API Usage
All requests → https://api.mail-check.tech
Auth → X-API-Key header
Format → JSON POST
Example S1 Request:
curl -X POST https://api.mail-check.tech/api/v0/validate/email \
-H "Content-Type: application/json" \
-H "X-API-Key: your_api_key_here" \

Example Response:

}
