Update :

Upon reviewing your account history, we've identified a few areas of concern that we'd like to address:

- Account Usage: We've noticed that you've created multiple single-code accounts, for maximum warm up email ids usage.. While we don't explicitly prohibit multiple lifetime deals account, this approach isn't aligned with our fair usage policy. Users must max stack one account before moving on to another account.

- Email Provider Choice: Our records show that many of your email IDs use Stackmail. While cost-effective, this provider has known connectivity issues, including complete restrictions from major networks like Microsoft. This can significantly impact email deliverability. We strongly recommend switching to a more reliable email service to ensure better performance.

- Support Requests: We've received numerous support emails from you. While we've responded to most within our sla many of these inquiries could have been resolved more efficiently through our community group. We kindly ask that you leverage our community for general questions to help us maintain a streamlined support process for account-specific issues.
