Yeah, Hi there…

So, you are on a lookout for SMTP server services. Right? I may guide you towards choosing a one for your company or your personal self. In last few years I have been almost scrolling the web for SMTP server which I could use to integrate into my service. It was over a month when I arrived at a solution which provided me all the stuff I needed. But I don’t want that to happen with you or anyone, it was just tiresome, so in this post we’ll be talking about Best Free SMTP Servers as a Service out there. Hey, If you’re still reading and haven’t grabbed a coffee and a notebook, you better do it. Cause, this is going to be really long, interesting and extensive.

Yeah, and one more thing, we’ll be considering services with free plan or a free trial period of or up to 12 Months.

Let’s dive deep….. wait no, no, no… Let’s ..mail it up.

But before that let’s give a small introduction to SMTP for those new to this term.

An SMTP (Simple Mail Transfer Protocol) server is an application that’s primary purpose is to send, receive, and/or relay outgoing mail between email senders and receivers.

When you send an email, the SMTP server processes your email, decides which server to send the message to, and relays the message to that server. The recipient’s inbox service provider, such as Gmail or AOL then downloads the message and places it in the recipient’s inbox.

Is an SMTP server the same as a normal server? Technically, yes. Like most servers, the SMTP server processes data to send to another server, but it has the very specific purpose of processing data related to the sending, receiving, and relaying of email. An SMTP server is also not necessarily on a machine. It is an application that is constantly running in anticipation of sending new mail.

And it’s better to get up on a service instead of hosting your own unless you have many I.Ps or you know an ISP which could give you may I.P
