To connect to Gmail SMTP (Simple Mail Transfer Protocol), you'll need to follow these steps.Obtain the Gmail SMTP server settings.
SMTP server name: smtp.gmail.com
Port number: 465 (SSL) or 587 (TLS)
SSL encryption: yes
TLS encryption: yes
User name: your Gmail address (e.g., firstname.lastname@example.org)
Password: your Gmail password
Enter the Gmail SMTP server settings into your email client or software. The exact steps to do this will vary depending on the client or software you're using, but in general, you'll need to go to the account or server settings and enter the information under "Outgoing (SMTP) Server."
Test the connection to the Gmail SMTP server. You can usually do this by sending a test email to yourself or another recipient to confirm that you are able to send emails through Gmail's SMTP server.
Note: Keep in mind that Gmail may block access to its SMTP server if it detects suspicious activity, such as a large number of emails being sent in a short period of time. If this happens, you'll need to contact Gmail support to resolve the issue.
