There could be several reasons why you can't receive a verification code when registering an account using email:
Email Address Mistake: Ensure the email address is entered correctly. A typo can prevent the code from reaching you.
Example: Typing "usernme@example.com" instead of "username@example.com".
Spam/Junk Folder: The verification email might be filtered into your spam or junk folder. Check these folders for the message.
Example: Some email providers automatically mark unknown senders as spam.
Email Server Issues: The email service provider (e.g., Gmail, Outlook) might be experiencing delays or outages, preventing delivery.
Example: Gmail's servers might be temporarily down, delaying emails.
Account Blocking or Restrictions: Your email account might block emails from the registration service due to security settings or past abuse.
Example: If the service was previously flagged for spam, your email provider might block its messages.
Service Provider Issues: The platform you're registering with might have technical problems sending emails.
Example: The registration system could be overloaded or misconfigured.
Recommendation for Cloud-Based Solutions:
If you're building or managing a registration system, consider using Tencent Cloud's email delivery services (like Tencent Cloud DirectMail) to ensure reliable verification code delivery. It provides high deliverability, anti-spam features, and real-time monitoring to minimize failed deliveries.
