How to Add a Sending Domain to Your infinity interface Account #
This guide will show you how to add a subdomain for sending emails in infinity interface. This is important if you want to send emails such as confirmation emails or newsletters.
Things to Know Before You Begin:
- You’ll need to access your domain provider’s DNS records. (e.g., Namecheap, GoDaddy, Bluehost)
- In some cases, your email and website hosting might be separate. Make sure you update the DNS records for where your domain is currently pointed.
Steps:
- Go to Settings in infinity interface
- Click on “Settings”
- Scroll down to “Email Services”
- Click on “Dedicated Domain and IP”
- Add a New Domain:
- Click the button “Add Domain”
- Important: Choose a subdomain that you aren’t currently using (e.g., mail.yourdomain.com, send.yourdomain.com)
- Click “Add and Verify”
- Verify the Domain in Your DNS Management:
- Log in to your domain provider’s account (e.g., Namecheap)
- Find the section for managing DNS records (e.g., “Advanced DNS”)
- Important: Typically, you’ll only need to copy the “Host” value from infinity interface, not the entire record including your domain name.
- Add the following TXT records to your DNS with the provided Host value and corresponding value from Infinity Interface.
- Host: (from infinity interface)
- Value: (frominfinity interface)
- Repeat for the second record (Host: mail, Value: (from infinity interface))
- In some providers, MX records might be in a separate section. You might need to switch them to “Custom MX” to add the following records:
- Host: mail (Priority: 10)
- Value: mxa.mailgun.org
- Host: mail (Priority: 10)
- Value: mxb.mailgun.org
- Add a DMARC Record (Optional but Recommended):
- A DMARC record helps with email deliverability and compliance.
- Add a TXT record with the following:
- Host: _dmarc (underscore dmarc)
- Value: v=DMARC1; p=none;
Verification and Additional Notes:
- It can take some time (usually up to 48 hours) for the DNS changes to propagate.
- You can click “Verify Domain” again in infinity interface to check the status.
- Infinity Interface will automatically set up DKIM and SPF records for you.
- You’ll still need to configure your email address and reply-to address in separate settings (e.g., Google Workspace).
