- No Malicious Content: You may not send emails containing viruses, malware, or any other harmful code or attachments.
3. Required Email Practices
- Double Opt-In Recommended: We strongly recommend using double opt-in confirmation for all email subscriptions to ensure recipients have explicitly consented to receive your emails.
