Temp Mail for Developers — API, Testing & CI/CD Integration Guide

Why Developers Need Disposable Email

If you're a developer, you've faced this scenario hundreds of times: you need to test a sign-up flow, verify an email-based feature, or create test accounts. Using your personal email is messy, and creating Gmail accounts for testing is time-consuming.

Temporary email solves this elegantly.

Common Developer Use Cases

1. QA & Automated Testing

  • Sign-up flow testing: Verify that registration emails are sent correctly
  • Email template validation: Check HTML rendering across email clients
  • Rate limit testing: Test how your app handles multiple sign-ups
  • Error handling: Verify behavior with invalid or expired emails

2. CI/CD Pipeline Integration

Automated test suites often need to:

1. Generate a temporary email
2. Register a new user account
3. Wait for verification email
4. Extract verification link/code
5. Complete registration
6. Run authenticated tests
7. Clean up (email auto-deletes)

3. Staging Environment Testing

  • Test email notifications in staging without affecting real users
  • Verify transactional emails (receipts, confirmations, alerts)
  • Test multi-language email templates

TempMail Pro API Reference

TempMail Pro provides a REST API that developers can integrate:

Generate a New Email

GET https://5mail.store/api/v1/inbox/generate

Response:
{
  "email": "[email protected]",
  "inbox": "abc123",
  "domain": "domain.com",
  "expires_at": "2026-08-10T18:00:00Z"
}

Check Inbox for Emails

GET https://5mail.store/api/v1/inbox/{inbox}/{domain}/emails

Response:
{
  "emails": [
    {
      "id": 42,
      "from": "[email protected]",
      "subject": "Verify your account",
      "received_at": "2026-08-10T17:05:23Z"
    }
  ]
}

Read a Specific Email

GET https://5mail.store/api/v1/email/{id}

Response:
{
  "id": 42,
  "from": "[email protected]",
  "subject": "Verify your account",
  "body_html": "<html>...",
  "body_text": "Click here to verify...",
  "attachments": []
}

Integration Example: Python + Selenium

import requests
import time
from selenium import webdriver

# Step 1: Generate temp email
response = requests.get('https://5mail.store/api/v1/inbox/generate')
email_data = response.json()
temp_email = email_data['email']

# Step 2: Use Selenium to sign up
driver = webdriver.Chrome()
driver.get('https://your-app.com/signup')
driver.find_element_by_id('email').send_keys(temp_email)
driver.find_element_by_id('submit').click()

# Step 3: Wait for verification email
time.sleep(5)
inbox = requests.get(
    f"https://5mail.store/api/v1/inbox/{email_data['inbox']}/{email_data['domain']}/emails"
).json()

# Step 4: Extract verification link
email_detail = requests.get(
    f"https://5mail.store/api/v1/email/{inbox['emails'][0]['id']}"
).json()

# Extract link from email body and complete verification
verification_link = extract_link(email_detail['body_html'])
driver.get(verification_link)

print("✅ Account verified successfully!")

Best Practices for Developers

  1. Don't hardcode temp emails — always generate fresh ones per test run
  2. Add polling with timeout — don't assume instant delivery, use a 30-second timeout
  3. Handle domain blocks — some services block disposable domains; have fallback logic
  4. Clean up test data — temp emails auto-delete, but clean up database records too
  5. Use environment variables — store API endpoints in config, not in code
  6. Rate limit awareness — don't hammer the API; add reasonable delays

Conclusion

Temporary email is an essential tool in every developer's toolkit. Whether you're running automated tests, building CI/CD pipelines, or testing email features in staging, TempMail Pro's API makes integration seamless. Stop creating throwaway Gmail accounts — use disposable email like a professional.
