How is using a Third-party email Provider better than On-Prem SMTP?
Enhanced Security - Third-party providers invest heavily in security measures, including encryption, spam filtering, and malware protection.
Reliability and Uptime - Providers like O365 and Gmail offer high availability and uptime guarantees, often with service level agreements (SLAs) that ensure your email service is always available.
