But before that, allow me to briefly talk about –
What Is SMTP?
SMTP or Simple Mail Transfer Protocol is a communication protocol that oversees the safe and successful transmission of electronic mails or emails.
And, the application that is well equipped to send and receive emails between two parties is referred to as an SMTP server.
For example, if I were to send you an email from my Gmail address to yours, Gmail can be labeled as an SMTP server.
Similarly, if I have a professional email address like – mail@wpbloggingpro.com and I send you an email with let’s say, Sendinblue, in that case, my SMTP server will be Sendinblue.
Now you’d be wondering, what’s the –
Difference Between Professional Free SMTP Servers & Gmail etc.
If you want to use emails with a free SMTP server with no authentication, then you can definitely use Gmail, Yahoo, Outlook, etc.
It would be ideal for day-to-day communication with your contacts and also if you don’t have a website.
However, if you have a website then using Gmail, Yahoo, etc. to send emails on the behalf of your website to your subscribers is highly frowned upon. In that case, using professional SMTP servers is the best option.
This enables you to use a custom professional email address like mail@wpbloggingpro.com to send bulk emails. Also, if you send bulk emails from Gmail, Yahoo, etc. your account will be banned for life.
How Do I Get A Free SMTP Server?
It’s quite simple actually..!!
All you have to do is sign up on the free SMTP servers list mentioned above (and also below).
After that, you’d need to configure a couple of simple settings and that’s it…
