Email marketing is not just about creating the perfect email for your audience. In fact, that is just half the part, the rest involves a world of complicated terminologies including delivery servers, relays, SMTP, MTA, IMAP and many more detailed metrics. For starters one may think that setting up a contact list and creating a simple email template with some copy would be all it takes to get started. But, there is so much more that goes into it than they see; from HTML files to server configurations.
SMTP Relay :
The interchange format of an email is the set of rules that allows an email to travel from one point to another point through the internet. As a name might suggest, the format is what helps shape the appearance of an email. These formats were created in 1982 and have been modified several times since then. The standards are made largely for server-server transfer which means a language can be created in order for two separate servers to be communicating with each other.
We can understand it as a buffer which allows for server-server transfer. It largely works in two steps;
Receives outgoing mail from the sending server.
Delivers the email to the requested destination server.
To understand this more clearly, let us take an example of a normal paper mail. If a letter has to be sent from Boston to New York City then the sender will deliver the letter to the Boston post office and it would be transferred to the NYC post office where a postman would later deliver the letter.
SMTP Relaying is this post-office to post-office transfer in the world of electronic mail which becomes server to server transfer.
Why use an SMTP relay?
You may now wonder, why do we really need to use an SMTP relay server like Adcrux, etc. Isn’t major email providers like Gmail, Yahoo, etc enough? The answer is, they aren’t. While they are functional in sending emails and still remain the backbone of sending any sort of communication to your mailing list, the truth is they were never created in the first place with businesses in mind which makes them a nightmare if you have to perform research and analytics on your campaigns. So, using an SMTP relay of your own will help you ease up your maintenance process and do advanced analytics. Another reason for using an enterprise level SMTP server like Adcrux is that ESPs such as Gmail, Yahoo, etc. impose a limit on the amount of emails which can be sent on any given day which businesses are bound to naturally exceed.
There are two ways of doing this. Either you can create your own infrastructure for SMTP relaying and set everything in-house which would require an insane amount of resources or you can use a service like Adcrux which would give you a dedicated SMTP server of your own, everything an SMTP server provides just without any hassle.
An SMTP server relay needs sophisticated internet infrastructure to be able to efficiently deliver emails directly into the inbox of the recipients. Companies which provide such services invest a lot of effort into creating a tangible product which satisfies the requirements of its customers.
Some Backend Action :
A component of email tracking software uses the format-based trace method, which enables users to correctly identify which mail server they are using. Another method includes embedding a tiny pixel into the message which contains a unique ID number, used to locate an individual's email address. The pixels can also be worked into images and attachments. Since these cannot be detected by the naked eye, changes to images can be made without the user knowing about it.
Every email sent to an ISP is inspected by a human being before it is transmitted. The person looking for the spam filter will scan the message, and based on its content, a spam score is assigned to it. If this score exceeds a certain value, the email will be blocked or routed to spam. To prevent this from happening, marketers need to follow certain rules when building their list and send emails. These rules ensure higher deliverability rates as well as good relationships with providers.
Final thoughts
Essentially what SMTP servers do is that they handle the security and heavy protocol lifting and make the lives of email marketers a little easier. This transcends to more time being able to be devoted to creativity in content and email design. In today’s world an SMTP server is a primary need for email marketing, whether you decide to buy from services like Adcrux or invest immense resources , it's one of those areas that you should not stop investing in as much as possible, especially when you're even beginning.
