What is SMTP and why is it important for Gmail?
SMTP stands for Simple Mail Transfer Protocol, which is a standard protocol used for sending emails across the internet. In the context of Gmail, SMTP allows users to send emails from their Gmail accounts through various email clients and applications. This can include popular software like Outlook, Apple Mail, and more. Understanding SMTP is vital because it ensures that your emails are delivered reliably to recipients without being marked as spam.
Having a functional SMTP setup is essential for both personal and professional communication. Issues with SMTP can lead to delays or failures in email delivery, which can disrupt workflows and communication. Therefore, if you encounter any problems with Gmail’s SMTP servers, addressing them promptly is necessary to maintain effective communication.
What can cause SMTP issues in Gmail?
