Here you will find the guides on how to use SmartSender SMTP Service.
Email is emerging as one of the most valuable services on the internet today. Most of the internet systems use SMTP as a method to transfer mail from one user to another. SMTP (Simple Mail Transfer Protocol) is a push protocol and is used to send the mail whereas POP (post office protocol) or IMAP (internet message access protocol) are used to retrieve those mails at the receiver’s side.
SMTP Fundamentals
SMTP is an application layer protocol. The client who wants to send the mail opens a TCP connection to the SMTP server and then sends the mail across the connection. The SMTP server is always on listening mode. As soon as it listens for a TCP connection from any client, the SMTP process initiates a connection on that port (25). After successfully establishing the TCP connection the client process sends the mail instantly.
Sending limits
Google limits the number of outgoing emails to 100 per day. When the limit is reached, you will not be able to send emails for the next 24 hours. More information on email sending restrictions can be found here.
