What is SMTP and Why Do Businesses Need It
SMTP (Simple Mail Transfer Protocol) is a protocol used to send emails over the internet. In business, having an efficient email sending system is crucial for communication with customers, sending notifications, and marketing campaigns. By using SMTP, you can automate email sending, saving time and increasing productivity.
Google Policy Updates 2026
Starting in 2026, Google has made several important updates regarding security in SMTP usage. One of them is the removal of less secure apps access and the implementation of safer authentication methods like OAuth2. App password implementation also becomes an option for users who enable Two-Factor Authentication (2FA). Additionally, daily sending limits need to be observed by users.
