SMTP Servers: The Story Behind Email Exchange Plus Free SMTP Server List

Many people get stumped at the abbreviation ‘SMTP’. What, exactly, is it? SMTP refers to ‘Simple Mail Transfer Protocol’, which, essentially, is the procedure that is responsible for email flow on the internet. And, ‘SMTP servers’ are the hardware that take care of the entire delivery process in any email communication.

The SMTP server has primarily two functions:

  1. If someone tries to send an email through an SMTP server, it verifies if they have the required permissions.
  2. If the necessary permissions are in place, the server delivers the message; and if it is unable to send a message, it informs the sender about it.

Thus, an SMTP server is a machine that is responsible for the whole email delivery process based on SMTP guidelines. And so, SMTP is crucial to pretty much all of our email communication. If one wishes to send emails in bulk, it is advisable to use a professional, outgoing email service which will allow bulk emails. That is because regular servers usually tend to come with limits in terms of the number of emails that a person sends per day. For example, Yahoo only allows one to send up to 100 emails in an hour.
