Verify your domain for email campaigns

Before sending email campaigns, you need to authenticate your domain. This step ensures your emails are trusted by providers like Gmail or Outlook, improving deliverability and preventing messages from going to spam.

Written by Jon Trasobares

Overview

Domain authentication is the first mandatory step when setting up Marketing Campaigns.

During this process, you will work in two environments:

  • Sage Sales Management → where you generate the records

  • Your domain provider (DNS) → where you configure them

Key concepts before you start

  • DNS (Domain Name System): It works like the “phonebook” of the internet. It tells where traffic for your domain should be directed.

  • Domain/DNS provider: This is the company where you purchased your domain (e.g. GoDaddy, Cloudflare, Arsys, Ionos). This is where you will make the required changes.

  • CNAME record: A type of DNS record used to “digitally sign” your emails.

  • TTL (Time To Live): Indicates how long it takes for DNS changes to be updated across the internet. A lower value (such as 1 hour) allows faster propagation.

Recommendation: use a subdomain

We recommend verifying a subdomain dedicated to marketing, such as mkt.yourcompany.com, and using it to send your marketing emails instead of using the root domain (yourcompany.com).

Benefits of using a subdomain

  • You protect the reputation of your main domain—which you may use for your website, corporate email and other services—by separating your marketing emails.

  • You simplify DNS management because you only need to add the verification records to the subdomain.

  • You avoid conflicts if the root domain already contains CNAME records or other DNS settings. Many providers already use the root domain and do not allow additional CNAME records without disrupting existing services. A dedicated subdomain does not interfere with this configuration.

For example, if your corporate domain is yourcompany.com:

You can also use other common subdomains, such as marketing.yourcompany.com or news.yourcompany.com.

The domain in the sender address must exactly match the verified domain.

Root domain or subdomain?

Use a marketing subdomain if you have already configured CNAME records on your main domain or if you use the root domain for your website or corporate email. This is standard practice in email marketing and reduces the risk of disrupting other services.

Before you start

Make sure that:

  • You have access to your domain’s DNS settings

  • You know who your domain provider is

  • The domain matches your sender email

Example:

If you send emails from info@yourcompany.com, your domain is yourcompany.com

Step-by-step

1. Add your domain

Go to:

Campaigns → Settings → Domain authentication

Click “Add domain” and enter your domain.

2. Enter your domain name

The platform will open a pop-up window. Enter your domain name here.

Recommendation: enter a marketing subdomain, such as mkt.yourcompany.com, instead of the root domain (yourcompany.com). For more information, see the Recommendation: use a subdomain section above.

IMPORTANT

Make sure the domain you enter exactly matches the domain in your sender email addresses.

For example, if you send emails from info@mkt.yourcompany.com, you must verify mkt.yourcompany.com, not yourcompany.com.

3. Generate DNS records

Click “Obtain DNS records”

The system will automatically generate 3 CNAME records. Each one includes:

  • Name

  • Value

These values are unique to your domain. You will need to copy them and paste them later into your domain provider’s DNS settings.

3. Access your DNS provider

Open a new tab in your browser and log in to your domain provider.

Look for a section such as:

  • DNS management

  • DNS zone settings

4. Add the records

Create the 3 records using the values generated:

For each record:

  1. Select the type → CNAME or TXT

  2. Copy the Name

  3. Paste it into the “Host” or “Name” field

  4. Copy the Value

  5. Paste it into the “Value” or “Points to” field

  6. Leave the TTL (Time to Live) as default

5. Save changes

Click “Save” or “Confirm” in your domain provider.

6. Check the status

Go back to Sage Sales Management.

Your domain will appear as:

Pending

⏱ Propagation time

DNS propagation is the time required for the changes made to your DNS records to be updated and applied across servers worldwide.

DNS updates are not immediate.

Once you have added and saved your records, return to Sage Sales Management and check the status of your domain:

  • Open the domain options (usually in the top right corner or in a three-dot menu)

  • Click “Update status”

Typical timing:

  • Usually: a few hours

  • Maximum: 24–48 hours

If the status is still “Pending” in Sage Sales Management, please wait and try again later.

7. Domain verified

Once everything is correct, the status will change to Verified, and you will be ready to send campaigns.

Common errors

  • Adding the full domain in the Name field (when the provider already adds it automatically)

  • Mixing up Name and Value

  • Not saving the DNS changes

  • Using a domain that does not match the sender email

⚠️ Multiple domains

If you use multiple domains (for example):

  • @company.com

  • @shop-company.com

You must verify each one separately.
