Simplify Business Communication Using Mail Relay SMTP

A mail relay SMTP service is the best way to manage such automated emails and batch sends.

What Is SMTP Relay?

SMTP (Simple Mail Transfer Protocol) is the protocol for delivering outgoing emails. It is a process to transfer an email from one mail server to another. Imagine that John from Company A wants to send an email message to Tom of Company B.

When John sends his outgoing message to Tom, his company’s defined SMTP Server connects to Tom’s incoming MX server (receiving mailbox). It then relays the email from John’s mail server to Tom’s mail server.

How Does Mail Relay SMTP Work?

An SMTP server is responsible for delivering the outgoing emails. However, it does not accept incoming emails. Most businesses use a mail SMTP relay service, which is a managed service and helps them send outgoing mails through Outbound SMTP.


Why Do Enterprises Need An SMTP Relay Service?

  • It is a convenient way to send emails within your organization, to your employees, or your established or potential clients and customers.
  • Commonly used ISPs like Gmail put a cap on the number of SMTP relays a user can send per day. Hence, organizations that need to send bulk marketing and transactional emails require an SMTP relay provider.

Caution – Open Mail Relay Can Be A Cybersecurity Threat

In earlier times, to facilitate mail deliverability between the separate closed email systems, open mail relays or third party relays were in vogue. However, these are vulnerable and allow hackers to route large volumes of spam. The owner of the server unknowingly throws away the computer and network resources to the attacker’s mercy, who can exploit it to his advantage causing loss of business, system crashes, and equipment damage.


Which One To Choose: SMTP Relay Software Or A Managed SMTP Service?

While some enterprises choose a managed SMTP service provider, some go for installing and maintaining the SMTP relay software themselves. For mail SMTP relay through the software, the software can easily be installed on any device, and it readily gets integrated into the device’s platform.

The software provider has a list of outbound SMTP server that enterprises can use for marketing purposes. However, it is tricky to find out which one is the best. In a managed SMTP service, this gets done through a third party.
