There is large database of e-mail address and random mails are sent to the addresses through SMTP servers. There are high chances that if 1000 mails are sent out, 100 mails will be opened and read. Out of that some might click on the company’s link that is provided in the e-mail. Thus, it is quite evident that the response rate is quite high in e-mail marketing.

Once the company starts getting ready responses from the emails that are sent out as a part of email marketing campaign, they tend to increase the volumes of the mails that are sent out. This is when problems start with SMTP servers. Each SMTP mail server has limitations and when overburdened, they start to create problems. This happens with anything and SMTP servers are nothing different. The first thing that happens on overburdening is that the SMTP mail server stops sending emails and a delivery failure notification is sent to the inbox of the email sender. The delivery failure message is also sent if the e-mail address of the mail recipient is wrong. When the server cannot find the address of the recipient, it redirects the mail to the sender with a delivery failure notification.

SMTP servers also help in keeping the mail system safe and secured. It helps in blocking spam and other unwanted elements from entering the inbox. Nowadays various kinds of SMTP mail server software are also available in the market that can be installed in the computer. It augments the process of e-mail sending and receiving.
