A List of SMTP and POP3 Servers


SMTP and POP3 are the most important technical aspects of email dispatch and delivery. In other words, SMTP processes the delivery of emails while POP3 handles the download and retrieval aspects of email. So, how does this work? You send a message using email clients such as Apple Mail, or Mozilla Thunderbird, it is then connected to a server via SMTP protocol and delivers your message. Then there comes a time when you want to download and retrieve your email. This is where POP3 or IMAP comes in. It is a protocol that retrieves your email. It is therefore necessary to enter the correct details for POP and SMTP when setting up an email account.

It is important to note that using free SMTP, especially if it associated with a common provider, you may suffer poor email delivery. Some clients also impose limits in terms of the number of emails you can send in a day, thus preventing you from sending a bulk message to your recipients. This could be disadvantageous to email marketers who are trying to reach out to their target audience through email. So, to be on the safe side, rely on a professional SMTP server such as turboSMTP when generating an email campaign as it will improve your email deliverability.

Configuring SMTP Server

Configuring an SMTP server when setting up an email account is crucial if you are looking to improve your email deliverability. You are just lucky that configuring the SMTP server is simple to comprehend. You only need to open your email software and add the right SMTP parameters in the window settings.

Remember if you are using a standard SMTP that is associated with common email providers such as Gmail and Yahoo, they will not ensure your emails are correctly delivered especially if you are sending a message to many recipients at once. The following is a simple procedure of how you can configure SMTP:

  • 1. Go to the "tools" menu, and select "Account settings" on Gmail or any other provider you are using.
  • 2. Select the voice “outgoing server (SMTP). When you chose that, you will see the buttons reading, “add”, “edit”.
  • 3. Click the "Add" button. This allows you to set up a new SMTP on your device. After clicking the add button, a popup window will appear.
  • 4. Fill in the details as follows:
  • Description:Here, type an informal name that you would like to identify the server with. Using your email provider’s name is highly recommended.
  • Server name: Be careful filling entering your server name. It is the actual SMTP server’s specification and you can consult the web page of your provider, or searching it on the list of SMTPs and POP3 servers.
  • Port: SMTP usually works with port 25 but it can also work with port 587.
  • Connection security: Because SMTP email transfer doesn’t offer secured internet connection, use STARTTLS or SSL/TLS extension, which provides encryption to an internet connection.
  • Authentication method: You can use passwords, CRAM-MD5, or KERBEROS.
  • Username: enter your email address here.
  • Configuring POP3 Server

    To add POP3 based account you will need to log in to your email account and on the top right corner, click the gear button;

  • 2. Direct your cursor to the “Accounts and Imports” and
  • 3. Click add an email account
  • 4. Enter the email address you want to set up and click next
  • 5. Select "Import emails from my other...” and click next
  • 6. Enter the POP server settings:
  • Username: enter your email address
  • Password: enter the password you use to sign in to webmail
  • POP server:
  • Port: 995

    Why You Need SMTP Server

    SMTP allows your messages to reach their final destination. In other words, your emails wouldn’t be delivered if you don’t configure it in your device. After typing your message or generating your email content, for email marketers, once you hit the send button, your email is transformed into a string of code that is then sent to the SMTP server. What SMTP do is processing that code and then pass your message to the intended receiver. Without SMTP, your message would be lost in translation and wouldn't, therefore, reach its final destination.

    Apart from that, the SMTP server the account from which the message is sent before passing on the message. This means that it protects your inbox from unverified accounts. The server sends back the message to the sender if is not delivered. This informs the sender that they either have the wrong email address or that they are being blocked from accessing some accounts.

    Which Smtp Server Do You Need to Connect To?

    It is highly recommended that you use ports 25 or 587. if you are looking to use SSL encryption, then use port 465.


    Of course, as mentioned earlier, if you need to send a bulk message to your readers, it is recommended that you use a professional server like turboSMTP. Using standard SMTPs which are associated with common email clients like Yahoo and Gmail could negatively affect your email delivery rate. On the other hand, dedicated outgoing service will ensure that your messages reach the intended destinations
