Server issues can arise due to a variety of reasons including, but not limited to:
- High Email Volume: Sending a large number of emails in a short period can overwhelm your server, leading to performance issues. - Poor Server Maintenance: Lack of regular maintenance can cause servers to crash or perform inefficiently. - Security Breaches: Hacking or other security issues can compromise server performance and email deliverability. - Improper Configuration: Incorrect settings in your email server can lead to authentication failures and other issues.
