What are the Advantages of SMTP Servers for Email Deliverability?
In the realm of modern communication, email remains an indispensable tool for businesses and individuals alike. Ensuring that emails are delivered promptly and reliably to their intended recipients is crucial. SMTP servers are a vital component in this process.
In this blog post, the Advantages of SMTP Servers for Email Deliverability, we will explore what SMTP servers are, how they work in email deliverability, and the numerous advantages they offer in the world of electronic communication.
What is an SMTP server?
SMTP, or Simple Mail Transfer Protocol, is a set of rules and conventions used to send and receive electronic mail messages. An SMTP server is the software responsible for facilitating the transfer of outgoing mail from the sender’s email client to the recipient’s email server.
How SMTP Servers Work in Email Deliverability
SMTP servers play a pivotal role in ensuring that email messages are sent and received effectively. Here’s how they work
Sender's Email Client
The email client communicates with the SMTP server when sending an email.
Authentication
The SMTP server verifies your credentials to ensure you are a legitimate sender.
Message Routing
The server determines the recipient’s email server and forwards the email.
Recipient's Email Server
The recipient’s email server accepts the email and stores it in the recipient’s inbox.
Delivery Confirmation
The SMTP server sends a delivery confirmation or error message back to the sender’s email client.
Benefits of SMTP Server
Now, let’s explore the advantages of using SMTP servers for email deliverability
Advantages of Using SMTP Server for Email Deliverability

SMTP servers are optimized for efficient email delivery, ensuring that your messages reach their intended recipients’ inboxes and not their spam folders.
Reliability
SMTP servers provide a reliable means of sending emails, reducing the chances of emails getting lost or delayed in transit.
Authentication and Security
SMTP servers use authentication mechanisms to verify senders, adding a layer of security to email communication.
Customization
Users have the flexibility to configure SMTP servers to meet their specific needs, allowing for customized email settings.
Fast and efficient
SMTP servers are designed for high-speed email delivery, ensuring that messages are sent and received promptly.
Detailed Tracking
Many SMTP servers offer tracking and logging capabilities, allowing senders to monitor the status of their email deliveries.
Basic SMTP Server Commands
While SMTP servers operate largely behind the scenes, understanding some basic commands can be helpful
HELO/EHLO
The greet command is used to identify the sending server.
MAIL FROM
specifies the sender’s email address.
RCPT TO
specifies the recipient’s email address.
DATA
initiates the email data transfer.
QUIT
Terminates the session.
Types of SMTP Server
SMTP servers come in various types, including open relays, closed relays, and dedicated servers. Each type of entity has its own unique set of advantages and use cases.
Open Relay SMTP Server
- An open relay SMTP server is configured to accept and relay emails from any sender without authentication.
- These servers are considered insecure and are commonly used by spammers to send unsolicited emails.
Closed Relay SMTP Server
- Closed relay SMTP servers require authentication for sending emails.
- They are more secure than open relays because they prevent unauthorized use.
Dedicated SMTP Server
- A dedicated SMTP server is exclusively allocated to a single organization or user.
- It offers greater control, customization, and reliability, making it suitable for businesses with high email traffic.
What is better: running your own SMTP server or using a Third-Party email service?
The decision between running your own SMTP server or using a third-party email service depends on your specific needs. Running your server offers more control but requires technical expertise and resources. Third-party services are easier to set up and manage but may have limitations in terms of customization.
