SMTP by Zapier – sending emails through mail servers

Wikipedia (https://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol) defines Simple Mail Transfer Protocol (SMTP) as “a communication protocol for electronic mail transmission.” Simply put, SMTP allows email client apps to send emails. Zapier allows you to connect to many commonly used mail client apps, such as Gmail or Zoho Mail. You may, however, have access to your own mail server and want to send emails independently. You can use SMTP by Zapier for precisely that purpose. SMTP by Zapier acts similarly to Email by Zapier; however, you can send emails without volume, recipient, and file size restrictions.

First of all, it may be useful to elaborate on what the difference is between a mail client and a mail server. The mail server is the software that runs on a computer server that processes email communications, such as Microsoft Server Exchange.
