What is a relay server?

A relay server is a server used to send emails from a sender to a recipient.

Basically, it acts as an intermediary between the email client and the destination server.

This server receives the sender’s email and forwards it to the recipient’s server.

The main purpose of a relay server is to ensure that the email reaches its destination safely and efficiently.

In addition, relay servers can handle large volumes of emails, which makes them ideal for companies running email marketing campaigns.

How does a relay server work?

To understand how a relay server works, it’s important to understand the basic process of sending emails:

Email design: the sender creates the email in their email client (such as Outlook, Gmail, etc.).
Initial step: the email client sends the email to the configured relay server.
Authentication: the relay server authenticates the sender to ensure that they have permission to send emails from the server.
Relay: the relay server forwards the email to the recipient’s email server.
Receipt: the recipient’s mail server receives the email and delivers it to the recipient’s mailbox.

This process ensures that emails are delivered efficiently and securely.

In addition, using a relay server can help avoid delivery problems such as blacklists and spam filtering.

Importance of relay servers in email marketing

Email marketing is a powerful tool to help companies keep in touch with their customers and prospects.

However, for an email marketing campaign to be effective, it is essential that the emails reach the recipients’ inboxes.

This is where relay servers play a key role.

Improving the delivery rate

One of the biggest challenges of email marketing is ensuring that emails don’t end up in the spam folder.

Relay servers can help improve the delivery rate by:

Email authentication: using techniques such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting & Conformance) to authenticate emails and reduce the chances of them being flagged as spam.
Sender reputation management: relay servers can monitor and manage sender reputation, ensuring that emails are not sent from IP addresses with a bad reputation.

Handling large amounts of email

For companies that send large quantities of emails, relay servers are essential.

They can handle several connections simultaneously, ensuring that all emails are sent without significant delays.

In addition, they can distribute the sending process between several servers, reducing the risk of overloading a single server and improving the overall efficiency of the sending process.

Email marketing use cases

Sending newsletters

For companies that regularly send newsletters to their subscribers, relay servers can help manage the sending process efficiently.

They can handle large email lists and ensure that the emails reach the recipients’ inboxes.

Promotional campaigns

Promotional campaigns that involve sending emails to thousands of recipients can benefit greatly from the use of a relay server.

These servers can handle the high volume of messages and improve the delivery rate, ensuring that the promotions reach the target customers.

Transactional messages

For companies that send transactional emails, such as order confirmations, shipping updates and account notifications, relay servers can ensure that these crucial emails are delivered in a timely and secure manner.

Conclusion

In short, a relay server is an indispensable tool for any company that wants to optimize email campaigns.

Not only does it improve email delivery rates, but it also offers security, control and scalability.
