Step 2: Go to the Domain Section
From the navigation menu, open the Domain section.
Step 3: Add Your Domain

Step 4: Get Your DNS Records
After adding the domain, you’ll see two options in the domain list:

Choose whichever method is more convenient for you.
Step 5: Update Your DNS Provider
Log in to your domain’s DNS provider (such as Cloudflare, GoDaddy, Namecheap, etc.) and add the records provided by MailCub.
Once the records are added, return to the MailCub portal and click Verify Domain.
