Domain Authentication Systeme.io

Sending emails with Systeme.io is a smart way to grow your business. However, before you begin, there is one crucial step you cannot skip. That step is domain authentication. In this article, you will learn how to authenticate your domain name for email sending.

Without it, your emails may not reach your audience. They could end up in the spam folder. Or worse, they may not get delivered at all.

Email services like Gmail and Outlook have become very strict today. They only trust emails that come from verified domains. If your domain is not verified, your emails look unsafe. This can hurt your open rates and your business.

The good news: Systeme.io makes domain authentication easy. No tech skills or outside help required. You can do it in a few quick steps.

In this guide, you will learn how to set up the domain authentication Systeme.io requires. I will walk you through everything. Step by step. This guide is made for beginners, so anyone can follow along.

Let’s get your emails into inboxes where they belong.

What Is Domain Authentication in Systeme.io?

Domain authentication proves you own your sending domain. Mine is thepassivecircle.com, as you know.

Email services like Gmail and Yahoo want to know that your emails are real. If they cannot trust your domain, your messages may go to spam. Or they may get blocked.

With domain authentication in Systeme.io, you add SPF, DKIM, and sometimes DMARC records to your domain settings. These tell email platforms that your emails are safe.

These records are like digital ID tags. They say, “Yes, this domain is real and safe.”

Without domain authentication, your emails may look fake. People may not open them. Your email list may stop working well.

But once you set it up, your emails are more trusted. They go to the inbox. Your open rates improve. And your chances of success go up.

Using domain authentication Systeme.io gives your emails the trust they need to reach your audience.

Why You Need Domain Authentication with Systeme.io

If you send emails with Systeme.io, you need to set up domain authentication. It is not just a good idea. It is a must.

Here is why it matters:

  • Your emails are more likely to land in the inbox.
  • More people will open and click your emails.
  • Gmail, Yahoo, and others will trust your domain.
  • You follow the latest email rules

Email platforms now block messages that look unsafe. If your domain is not verified, your emails can get marked as spam. Guess what! I’ve faced it at the beginning of my Systeme.io journey. It didn’t feel good!

This is very important if you do email marketing, affiliate marketing, or run an online coaching business. You need your emails to reach your audience.

Setting up domain authentication Systeme.io helps you avoid big problems. Do it now so you don’t lose leads or sales later, like I did.

Step-by-Step: How to Set Up Domain Authentication in Systeme.io

Setting up domain authentication may sound hard, but it’s not. Just follow these simple steps. For me, it was like tons of work to do! Search the website, watch tutorials, and research the best approach to do it. I’m hoping to get an easy solution!

I did it and share the best approach so that you don’t have to repeat the whole struggle like me. Just follow the process I stated below:

Step 1: Log in to your Systeme.io account

Systeme.io login

Go to your dashboard. Click on Settings. Then go to Email Settings and choose Custom Domain.

Step 2: Add your domain name

Type in the domain you want to use. This is the name that shows up after the @ in your email.

If you’re using the same domain for both WordPress and Systeme.io (for email or funnel setup), and you don’t configure it carefully…Conflict happens. Systeme.io overrides your domain, and visitors land on a broken page.

And trust me, if you’re just blindly following tutorials from YouTube (like I did), You’ll never know why it’s happening until someone clicks your site and gets confused.

Use a subdomain for Systeme.io instead.
Here’s what happened to me and how I fixed it by adding a subdomain for Systeme.io.

Step 3: Copy the DNS records

Systeme.io will show you special records. These are SPF and DKIM. Copy each one carefully.

Step 4: Open your domain provider

Log in to where you bought your domain, like GoDaddy or Namecheap. Go to the DNS settings. Paste each record as a new TXT entry. I’m currently using ExonHost. So the Screenshot based on ExonHost. But the steps are same for Namecheap, GoDaddy, Hostinger etc.

Step 5: Save your changes
