What is the weakness of SMTP?

What are the advantages and disadvantages of sending an email?

There are a bunch of benefits of email marketing but also there is a big list of drawbacks and disadvantages to any form of marketing.

So as you read this, here is the pros and cons of email marketing.

Pros. Ease of Implementation. There is no better way of implementing an Email Marketing strategy than a mail merge. You can send messages quickly using this solution which makes it a preferred option.

Reachability. You can send mass emails to your customers without getting them to spam their friends or colleagues. These emails don't have to be filtered by the recipient.

Cost-Efficiency. Email campaigns are quite affordable than many other marketing methods such as print and display advertising. It makes all the sense when the return is much higher for not investing a lot.

Easily Tailorable. You can customize each individual email content to match the brand of your business. This gives your message to the receiver a personal touch.

Quick Results. You get to see immediate results of the campaign when you receive emails from your list. You can immediately see how this has benefited them and thus increases the rate of returning customers.

User Experience. When you send emails from your mailbox, you get the feel of receiving an email without opening it in your inbox. This means that even though your messages may seem cold and heartless, you can still make a connection with your contacts.

Easier Tracking. You can track all your communication with your prospects, especially if you decide to use an email marketing platform. Also, you can identify your top prospects.

Low Cost to Receive. Unlike most other forms of marketing, emails do not have any fees to receive their mail. This makes them much more affordable than their traditional counterpart.

Effective. A direct line on the heart makes emailing a lot more effective than social media. You can reach your audiences quickly and have a great impact on their minds.

Instant. You have fast access to information, products, and services you sell even when they are offline. Emails allows you to respond to your contacts in a timely manner and can even be answered via mobile phone.

Personalized. Once you create an email for your recipients, you are giving them the chance to communicate with you.

What is the purpose of the SMTP server?

It's a question that's always had a lot of variation in opinions.

I often try to answer it from the viewpoint of software configuration, but sometimes as a user, I still find it hard to define. After all, email has so many varied uses: E-learning & online learning. SMS & other messaging applications. Customer support messages. Business and personal correspondence. Marketing communications. Personal and collaborative messages. Email for notifications and alerts. Email for chat & direct messages. Email attachments. Email as a file. Email as a command shell. Email as a virtual storage space. Email for publishing things online.the list could easily go on forever.

So why would we even have SMTP in the first place? Well, we wouldn't. Without SMTP you would just be able to send mail locally on your own. But if we ever created any kind of network service for computers to use, we would need SMTP servers for incoming mail. (Actually we can avoid that; SMTP is also designed as a simple, lightweight protocol for a one-to-one mail transfer over a computer network with no restrictions. But we're talking about server here, so we can ignore it for now.)

This is, however, what SMTP is good for, right? And this is how it started; there was no email server. People built their own email servers by hand on top of the SMTP protocol.

Then a few things started changing. The Internet has grown in reach, enabling us to connect with computers in different parts of the world, as well as computers inside the home itself. More people work remotely, and they need email services to get things done. We've seen the rise of cloud computing. We've seen the rise of mobile devices, tablets, and smartphones. As these things rise in importance, they can't be left to the old fashioned desktop; they require centralized computing in homes and businesses alike.

But these things aren't quite ready for use today, and in fact email still isn't a complete tool when using a mobile device. So for now we have to send email through a computer somewhere, and we need to route email through IP networks that use routing protocols to locate a computer when an email is sent.

What are the limitations of SMTP protocol?

Is there any thing that SMTP protocol cant do? The basic limitations of SMTP are the same as those of the email protocols (SMTP, PGP, MIME etc.). There are many more limitations than that.

First of all SMTP is a message transport protocol. It has no security. That's why it is called "Simple Mail Transport Protocol". Email is only a messaging protocol, not a transport protocol. You need a transport protocol for email like SMTP if you want to send emails from one address to another.

You have a lot of other options for secure message transport. You can use X.509 certificates, S/MIME, PGP, OpenPGP etc. These protocols offer a lot more security than SMTP.

If you want to know which protocols offer the best security, you can find this information on the Wikipedia page about electronic mail security.
