- The significance of an SMTP relay service.
What is an SMTP relay service?
SMTP, or Simple Mail Transfer Protocol, is the fundamental process that enables users to send, relay, and oversee outbound emails. An SMTP relay service, also known as an SMTP gateway service, takes this process to the next level by facilitating the sending of transactional and marketing emails.
Instead of you managing the SMTP server, you can entrust this responsibility to the SMTP relay service, which handles the server’s maintenance and operation.
But why is having an SMTP relay service crucial, and how does it operate?
Accessible via the cloud and through web browsers, peer-to-peer email is often insufficient for specific mass email campaigns and programs. Businesses that send bulk emails, such as newsletters or automated messages triggered by user interactions, often require tailored solutions. Utilizing an SMTP relay server for email distribution provides you this exact service.
How does an SMTP relay server work?
When an Email Service Provider (ESP) attempts to send an email, it connects to the configured SMTP server for communication. Once this connection is established, the email is routed through an SMTP relay server for delivery.
SMTP relay servers function in a manner analogous to traditional mail delivery. In this analogy, the server serves as the equivalent of a postal service. Imagine you need to send a letter. You write your address and the recipient’s address on an envelope, drop it off at your local post office, and the post office determines the closest post office to the recipient and forwards the letter accordingly
When you send an email, the message contains the recipient’s destination address, as well as your return address, including your email address, IP address, and timestamp. Your local server uses this information to send the message to the recipient’s server for successful delivery.
What is SMTP mail relay?
SMTP mail relay is the process of transferring an email from one server to another for final delivery.
For example, if you work for Company A and send an email to someone at Company B, you connect to your company’s SMTP server.
Subsequently, your company’s SMTP server delivers your email to Company B’s server. This relay of an email from one server to another is termed mail relay.
However, if you send an email to someone with an email address within the same domain as yours, there is no need for a second server’s involvement. This is not considered mail relay, akin to sending a physical letter within your own town, where your local post office manages both sending and delivery.
SMTP mail relay is employed to route emails through a trusted third party, particularly when handling high email volumes. It excels in sending large batches of emails, such as newsletters or automated transactional emails, like delivery confirmations and password resets.
What is a public SMTP relay server?
When an SMTP relay server is public, it has its limitations. Public SMTP relay servers are free but have restricted capabilities for sending mass marketing emails.
To counter spam, many internet providers place a cap on the number of SMTP relays conducted daily.
Because businesses often exceed the public SMTP relay limit due to their Bulk Email needs, they require enterprise-level solutions to ensure emails reach their recipients without being labeled as spam. An SMTP relay provider can assist businesses in efficiently delivering a large volume of emails while maintaining deliverability.
What is an authenticated SMTP server?
SMTP authentication, or SMTP AUTH, is an extension that provides clients with access to an SMTP server through an identification mechanism. Authenticated SMTP relay involves verifying the sender’s credentials before processing and relaying the email.
This process is designed to secure email delivery by preventing unauthorized parties from registering with an authenticated SMTP relay server.
In contrast, open mail relays lack this security requirement and are more susceptible to misuse. SMTP authentication safeguards your server from spam generated by malicious emails, ensuring that trustworthy users can send and receive emails securely.
Why is an SMTP relay service important
Managing your email server for peer-to-peer communication is relatively straightforward when you’re dealing with a limited number of recipients.
However, when you are doing cold email marketing to tens of thousands of leads or any other type of bulk emailing, they become less unique and are often flagged as spam. This is where an SMTP relay service becomes invaluable.
Using your primary peer-to-peer email server for bulk emails can harm your delivery rate and consume bandwidth, potentially causing delays in sending and receiving peer-to-peer emails.
Constantly monitoring your email server to prevent essential emails from landing in spam is expensive and time-consuming.
