Have you heard about SMTP…?/ What does SMTP mean?/ What does SMTP stand for?|How SMTP works step by step?

If not! not to be a worry. SMTP is a mail server that is responsible for sending and receiving our emails and its full name is Simple mail transfer protocol|How SMTP works step by step|

Almost we all use email clients like Gmail, Yahoo, Rediff and etc for sending our emails nowadays, so these email clients use their own SMTP server for sending our emails and vice versa.

When we send an email then first it goes at our SMTP or sender-SMTP and it reaches the receiver SMTP server and then reaches the receiver end.

These are the professional email client which allows us to send the professional emails and chat.

But if you are running a business and want to promote your product or services then this email client will not be sufficient to do the same, because they don’t allow us to send the emails in bulk.

Then what is the solution for this….?/What is SMTP and how does it work?

Email marketing is the solution for this, nowadays there are various email marketing services available that allow to send us emails in bulk.

Few email marketing clients use their own SMTP to send the emails and few use third-party SMTP services like amazon SES with their SMTP relay service and etc.

For sending a successful email campaign you need to verify your email as well as domain address.

Once you are set with this verification your email will lands in the customer inbox for sure.

There is a list below for the SMTP service provider most of them provide complete email marketing solutions with them.

Amazon SES(AWS) SMTP

ConvertKit SMTP

MailGet Bolt SMTP

MailGun 

PostMark SMTP

MailJet SMTP

Sendgrid SMTP

Spark post SMTP

Gmail SMTP

Yahoo SMTP

If you are looking for a third-party SMTP then I will suggest Amazon AWS from my personal experiences.

Aws is very legit, authentic, and available at a very low cost, it is pay per your use.

It only charges $1 for the 1000 emails you send.

It provides all tracking facilities like Bounce and spam.

Otherwise, you can go with the email marketing solutions listed above which provide inbuilt SMTP.

You can try this ESP, I am a fan of this ConvertKit SMTP service, you might consider it a little costly but it is a legitimate service for sure.

In our next post, we will let you know how to verify the email address and domain address successfully.

Quick Q&A: How SMTP works step by step.

Which model uses SMTP?

SMTP uses a mail processing model to send and receive emails. Very first a mail is sent to the SMTP server by a mail client or mail agent and then the SMTP server sends this email to another mail server which is a receiver mail server and thus this email goes to the receiver mail client and then the user can read the email through this mail agent.

Is SMTP secure?

SMTP standard sends the emails without any encryption and authentication so it is easily open and viewable in between by the third party or hackers. But at the client-side user can get the security by using secure MIME(multipurpose internet mail extensions) and Pretty good privacy((PGP), but user involvement is necessary for both of these schemes of security solutions.

Can receive but not send emails?

Few users face this type of problem where they are able to receive the email but they are unable to send the emails. The most common reason for this is that the user doesn’t set the Outgoing SMTP configuration to send the emails. Probably the authentication required by the outgoing SMTP server is not checked.

What is the SMTP IP address?

It is simple to find out the IP address of the SMTP server like we find out for a website. Using the Command window you can get it easily by typing a simple command like “ping mail.servername.com” and then hit the enter button and you will get the IP address for your SMTP server. You can also use a few free online tools to get the IPP address for your SMTP server.

Is SMTP still used?

SMTP is mostly used for sending out emails by an email client like (Microsoft outlook, thunderbird, Apple mail). But the fact is that the SMTP server has been using by most of the email service providers to send emails or bulk emails. Like almost all the ESP using the SMTP servers to send their commercial and non-commercial emails.

Common SMTP Error codes?

When an email sending get fails then SMTP generates an error code which may or may not specify the reason behind the email failure. For example, if you get ‘put plainly’, it means that your email could not be delivered. And if SMTP shows an error 550 then your message could be failed for various reasons for this you need to see the remaining error logs in detail which are provided by almost all the SMTP. So the common error code informs you about the problem of email failure so that you can rectify it easily.

What is SMTP access?

SMTP access is just like permission where you are allowed to send the emails from your own email server. But your mail administrator can limit the amount of volume that you can send through your email server. And you must have a direct mail account in order to access the SMTP access for your mail server.

What are the SMTP ports?

The standard port used by the SMTP servers is 25, 4658, 587.

What is an SMTP client?

Inside the SMTP server, the SMTP client allows sending the email notification for verifying the various credentials for authentication purposes.

What’s the difference between SMTP and IMAP?

SMTP stands for simple mail transfer protocol, whereas IMAP stands for Internet message access protocol. SMTP is responsible for sending and receiving emails within the SMTP mail servers. Whereas IMAP is used for managing and retrieving the message from the mail servers.

Does Google use SMTP?

Yes, this is a google SMTP server and this is a public email service provider and is free to use. Any person who is having a Gmail account or google account can access this email service for free of cost. this Gmail SMTP server manages more authentication and TLS/SSL(depending upon your mail client) securities while sending and receiving the emails.

What is the difference between pop3 and SMTP?

SMTP is working is to transfer the mail from the user’s computer system to the mailbox of the receiver mail server. And then this pop3(post office protocol version 3) protocol retrieves and manages the mail from the receiver mailbox to the receiver computer system.
