Introduction:

In today’s digital age, email marketing is an essential component of any business’s marketing strategy. It’s a cost-effective way to communicate with customers and potential clients, build brand awareness, and increase sales. However, to ensure your emails are delivered to the right inbox and reach their intended audience, you need a reliable SMTP server.

SMTP stands for Simple Mail Transfer Protocol, which is the standard protocol used for sending and receiving emails over the internet. An SMTP server is responsible for sending outgoing emails from your email client or marketing automation software to the recipient’s email server. In this article, we’ll explore how an SMTP server works, its benefits, and how to choose the best SMTP server for your business needs.

How SMTP Server Works?

SMTP server works in a series of steps to deliver the email from the sender to the recipient’s inbox. Here’s a brief overview of the SMTP server process:

Step 1: Authentication – Before sending an email, the SMTP server authenticates the sender’s credentials to prevent spam and ensure security.

Step 2: Address Resolution – The SMTP server looks up the recipient’s email address and finds the recipient’s email server.

Step 3: Connection Establishment – The SMTP server establishes a connection with the recipient’s email server using the Transmission Control Protocol (TCP).

Step 4: Message Transfer – Once the connection is established, the SMTP server sends the email message to the recipient’s email server using the Simple Mail Transfer Protocol.

Step 5: Delivery – The recipient’s email server receives the email, scans it for spam or viruses, and delivers it to the recipient’s inbox.
