Why is SMTP authentication necessary for your email program?

Would you encourage someone else to spoof your brand, damage your email infrastructure, or send emails from your account?

No, right?

When you don’t secure your emails properly, spammers could do all these destructive activities using your email account.

Time and again, spammers have proven that they operate where there is the least resistance.

SMTP refers to the Simple Mail Transfer Protocol.

It is a simple way of sending emails. 

An email communication channel is widely preferred for the security of a sender, and the email service provider offers to guard the email program. 

This is where SMTP authentication comes into the frame.

SMTP authentication not just allows you to leverage the features available in your SMTP service provider but also protects your email programs from the possibility of spam and unauthorized use.

You might have put in a lot of effort and time to find emails and build your prospect list. All your efforts will go in vain if you fail to secure your email account.

Does it make sense to you?

How did you build your prospect list? Did you buy it from a third-party source? If you did, I would recommend you stop purchasing email databases from a third-party source.

Instead, use GetEmail.io to find an email address; this tool uses big data and a machine-learning algorithm to locate the correct email format of the prospects.

All you have to do is enter your prospects’ name and company domain, and the tool will quickly get the email addresses.

As a beginner, you may go with the free plan instead of investing money.

You can sign for the free plan and get to find up to ten email addresses every month. 

When you find the tool effective or your requirement exceeds ten emails per month, you might opt for the paid version.

I hope you find this tip valuable.

As we go ahead, we shall talk more about SMTP authentication.

SMTP Authentication

It is a method of securing your email communication. This is utilized when a user logs in with a valid authentication mechanism by the submission server.

What will happen if you don’t authenticate?

When you don’t authenticate, your email account is highly vulnerable to spammers.

These bad actors might damage your email program with email spoofing. This is a tactic where the spammers send emails with an email address that they don’t own.

Besides this, your prospects (i.e., recipients) might consider your mail as untrustworthy; This means that you could send unauthenticated email contents through your account.

And if the email gets delivered at all, it will ultimately lead to spam delivery and high filtering rates.

This emphasizes the fact that your account could be exposed to phishing attacks when someone is spoofing your sending domain. 

When you use domain authentication or single sender verification, it forces the users to authenticate their ownership of the email account to eliminate spoofing.

Final Thoughts

You can ensure that your email infrastructure is protected from spammers and spoofing attacks when you have a secure SMTP server.
