You will find a lot of free SMTP servers out there, but few of them are reliable and secure. This is the reason we bring you the list of 10 best free SMTP server that are simple, secured and reliable (well).

If you’re a small business owner, chances are you’ve already heard of the popular, free email service “Gmail” and the need for a reliable, secure SMTP server to send and receive all your email. Luckily for you, we’ve gathered up a list of 10 free SMTP servers that are suitable for small businesses. There are also plenty of other free SMTP servers available for you to choose from, but these are the best.

SMTP stands for Simple Mail Transfer Protocol and is a communication protocol for sending messages electronically. SMTP was first developed in the early 1970s. Simply put, it is software that allows you to send emails over the Internet. Through a storage and routing process, SMTP moves email between different networks. SMTP does this work at every stage.

What is an SMTP relay server?

SMTP relay is used when we want to send mass emails through a trusted third party. Normally there is a limit to the number of messages that can be sent per day, but with an SMTP relay server you can send large emails. SMTP relay works in the cloud, not in your own data centre. An SMTP server is an application whose main purpose is to send, receive or forward outgoing e-mail between senders and recipients.

Why do I need a free scalable SMTP relay server?

SMTP is very important. Without an SMTP server, the email will not reach its destination. Once you click send, the email is converted into a line of code and sent to the SMTP server. The SMTP server then processes the code and sends the message.

Sending peer-to-peer emails is much easier, and it will be very difficult to send mass emails in the same way as peer-to-peer emails. There is also a daily limit to the number of messages you can send and receive. Therefore, in these cases of mass emailing, we need help to ensure that the messages are not considered spam. SMTP helps the user in this situation.

As the business grows, so does the need to send masses of emails, and outsourcing an SMTP relay server is a common practice to keep things running smoothly. Most email senders use the SMTP protocol to send bulk messages. In addition, marketing automation can be used to create rich, responsive marketing campaigns that increase subscriber engagement.
