How to send Systeme.io emails from your own domain, step by step

Systeme.io gives you unlimited emails on its free plan, but it will not send a single newsletter until it knows who the sender is. Sending from an address on your own domain, such as hello@yourdomain.com, takes four steps and one wait. We went through all of them on 14 November 2026 while testing the free plan for our Systeme.io review. This is the exact order that worked, and the places where it did not.

Before you start

You need:

• A Systeme.io account. The free plan is enough.
• A domain you control, and access to its DNS settings at your registrar or host.
• A mailbox on that domain that can receive email, because Systeme.io sends a confirmation link to it.

Why not just use Gmail? You can verify a Gmail or other free address in a few minutes. But marketing emails sent “from” a free address through another company’s servers are more likely to land in spam, because the free provider cannot vouch for them. An address on your own domain, with the domain authenticated, avoids that. Our test email from our own domain reached the Gmail inbox, not spam.

Step 1: create a mailbox on your domain

If your domain already receives email, skip this step.

Our domain is with Hostinger, where we created the mailbox in hPanel under Emails, picking the domain and then a hello mailbox with its own password. hPanel also added the DNS records the mailbox needs (MX, SPF, DKIM and a basic DMARC record).

Check your other DNS records afterwards. When we switched email on, the domain’s existing Google Search Console verification record disappeared from DNS. Google rechecks that record, so losing it would eventually have cost us access to Search Console. We added it back, next to the new SPF record. If you verified your domain with Google or anyone else through a TXT record, look for it after any email setup.

Step 2: add the address as a sender in Systeme.io

1. In Systeme.io, open Settings, then Emails.
2. Under Verified email addresses, click Add new email address and enter your address.
3. Open that mailbox and click the confirmation link Systeme.io sends.

The address now shows as Verified, but with a warning icon. Hover over it and Systeme.io explains that you still need to authenticate the domain. Until you do, the address does not appear in the sender list when you write a newsletter.

Step 3: authenticate your domain

On the same settings page, under Domains, click Add new domain and enter your domain without www. Then click the eye icon under DNS settings to see the records to add.

Add these at your DNS provider:

Type	Name	Value
CNAME	si followed by a number (shown on your screen)	inbound.systeme.io
CNAME	systemeio1._domainkey	key1.systeme.io
CNAME	systemeio2._domainkey	key2.systeme.io
TXT	_dmarc	v=DMARC1; p=none; rua=mailto: plus a report address

Three things to get right:

• Names. Most DNS panels add your domain to the name automatically. Enter systemeio1._domainkey, not systemeio1._domainkey.yourdomain.com, or you end up with the domain twice.
• Only one DMARC record. If your domain already has a _dmarc record (ours did, from the email setup), replace it rather than adding a second one. Two DMARC records count as none.
• The report address is public. The rua=mailto: address goes into public DNS, where anyone can read it. Systeme.io’s dropdown suggested the account’s login address, which for many people is a personal inbox. Pick an address on your own domain instead. The dropdown only changes the text shown for you to copy; it is not a saved setting.

To confirm the records are live, look them up in a public DNS checker or run:

nslookup -type=CNAME systemeio1._domainkey.yourdomain.com 8.8.8.8

Ours showed up on Google’s and Cloudflare’s public DNS within a minute.

Step 4: wait for the domain check

This is the part you cannot speed up. Systeme.io checks the domain on its own schedule, and there is no button to run the check again. The only option in the domain’s menu is Delete. We did not try deleting and re-adding the domain, since that could mean setting the records up again.

Our records were correct within a minute, but the domain stayed Pending for hours and switched to Verified later the same day. If yours is still pending after a full day and the records check out, contact Systeme.io support from the chat bubble in the dashboard.

Step 5: tag the people who should get the newsletter

A Systeme.io newsletter is sent to tags, not to your whole contact list. A newsletter with no tag warns that no one will receive it.

1. Open CRM, then Tags, and create a tag, for example newsletter. Tags cannot be created from the newsletter screen or from a contact page.
2. Add the tag to your contacts, or set up your sign-up form’s automation to add it to everyone who subscribes.

The free plan allows one tag and one automation rule, so spend them on this.

Step 6: write and send the newsletter

1. Open Emails, then Newsletters, and click Create newsletter.
2. Fill in the subject and sender name, and pick your address under Sender email address. It appears only once the domain is verified.
3. Choose the visual editor or the simple text editor, and save.
4. Write the email. In the Recipients panel, under Tags, include your tag.
5. Open the arrow next to Save draft. Save and test sends a preview to you only, and Save and send sends it to everyone with the tag, after a confirmation.

Read the email before you press send. In our test, the simple text editor dropped characters when long lines were typed quickly, cutting sentences off mid-line. Typing in shorter bursts fixed it.

If something goes wrong

What you see	Likely cause	Fix
The sender list says “No options”	The domain is not verified yet	Finish step 3 and wait for step 4
The address is “Verified” with a warning icon	The domain is not authenticated	Step 3
The domain stays “Pending”	Systeme.io has not re-checked yet, or a record is wrong	Check the records on public DNS; contact support after a day
“Without a tag, no one will receive this newsletter”	No recipient tag chosen	Step 5
Sentences cut off in the email body	The editor dropped typed characters	Retype in shorter bursts and check before sending
Search Console or another service lost verification	Email setup replaced a TXT record	Add the old verification record back

How long it takes

The clicking takes about 30 minutes, most of it in your DNS panel. The wait in step 4 can take most of a day, so start it before you write the newsletter.
