Email is deceptively simple.

Create a promotional email, add some text and you’re ready to hit send!

Next thing you know, your clients are reading your email on their computer screens around the world! Sounds simple, right?

Well, not exactly.

The truth is, email delivery is quite a complex process!

While more mail means more success, it also means more risk! If you want to send out huge amounts of email, you need an email service provider to get your email to the right inbox, and not the spam folder.

Here’s an explanation of how email sending works – so that you’ll be the go-to-guy in the office when it comes to email!

Basic, Small Scale Email Sending

This kind of email operation involves sending email to a small mailing list via an Outlook account, for instance. Small scale email sending offers no reporting or analytic tools and is almost identical to how you socially use email.

This kind of communication has been largely replaced by SMS / text in the social world, but is still used daily in the professional environment.

For example, the sending process for basic email follows this procedure:

  1. You send your email message from your computer to an SMTP – that’s Simple Mail Transfer Protocol.
  2. The SMTP sends the information to a DNS (Domain Name Server) which translates the email address into a unique IP (Internet Protocol) address.
  3. The DNS server sends the message to an MTA (Mail Transfer Agent) server which decides how best to deliver your mail – kind of like how a regional post office finds local post offices and PO boxes.
  4. Your target gets the email from her service provider when she logs into her account.

Now this is all well and good for private communication, but what if you want to send thousands of emails out at a time, like with email marketing?

Typical ISPs like the ones described above aren’t equipped to send mass email blasts out and come with a slew of issues. For one, you have no way to track and report back on your email marketing performance so you’ll never be able to improve your campaign! In addition to this, your email is at a much higher spam risk, meaning you could be blacklisted as a spammer and be penalized on the rest of your outgoing emails!

That’s where we come in!

Email Marketing Sending

Your first step into email marketing is partnering up with an Email Service Provider (ESP) such as SharpSpring Mail +.

Basically an ESP operates and maintains software and sending hardware that is built to deliver bulk email. In addition to this, a good ESP offers reporting tools, testing tools and other advanced functions that help you track and improve your email marketing efforts.

At its core though, ESPs are there to do one job for you, and that is to deliver mass email blasts. They accomplish this by having a vast group of ISPs (including DNS, MTAs and sender IPs) that will send your email without it getting marked as spam, blacklisted or blocked.

However, for senders who send large and often, this extensive range of sender IPs is sometimes not enough to avoid being blocked or penalized in some way.

If you’re planning on delivering tens of thousands of email and sending them often, you’re going to need an SMTP relay if you expect fast, on target delivery.

SMTP Relay Service

So what is an SMTP Relay Service? I guess you could call it a monster mail machine!

SMTP Relay does away with sender checking and spooling measures meaning that it allows mass sending without having to go through regular spooler bottlenecks. By going through one relay rather than various IPs, we simplify the process for you.

This essentially means less processing which means it can handle heavier loads – and faster!

A very simplistic way to think of this is that an SMTP Relay acts like a “larger pipe” to send your emails through. No bottlenecks in delivery, no immense sending queue times and no worries about your deliverability!

When compared to smaller scale email sending as outlined above, SMTP Relay works like this:

  1. You send your email message from your computer to an SMTP relay.
  2. The SMTP relay translates and sends the information to your client’s ISP.
  3. Your client gets the email from her service provider when she logs into her account.

Simple, clean and efficient!
