Adding Domains to MailSentinel

This guide walks you through adding and verifying domains in MailSentinel.

Prerequisites

Before adding a domain, ensure you have:

• Access to your domain's DNS settings
• A MailSentinel account (organization owner or admin role)

Step 1: Navigate to Domains

1. Log in to your MailSentinel dashboard
2. Click Domains in the sidebar
3. Click Add Domain

Step 2: Enter Your Domain

Enter your domain name (e.g., example.com) in the input field.

example.com

Note: Add the root domain, not subdomains. MailSentinel will automatically monitor subdomains.

Step 3: Verify Ownership

To verify you own the domain, add a TXT record to your DNS:

DNS Record Details

Adding the Record

Cloudflare:

1. Go to DNS settings
2. Click "Add Record"
3. Select TXT type
4. Enter the verification value
5. Save

GoDaddy:

1. Go to DNS Management
2. Add a new TXT record
3. Leave Host as @
4. Paste the verification value
5. Save

AWS Route 53:

5. Enter the verification value
6. Create records

Step 4: Complete Verification

After adding the DNS record:

1. Return to MailSentinel
2. Click Verify Domain
3. Wait for DNS propagation (usually 5-15 minutes)

Tip: DNS changes can take up to 48 hours to propagate globally, but most changes are visible within minutes.

After Verification

Once verified, MailSentinel will:

1. Scan DNS Records - Check for existing DMARC, SPF, and DKIM records
2. Start Monitoring - Begin processing incoming DMARC reports
3. Generate Insights - Provide recommendations based on your configuration

Managing Multiple Domains

You can add multiple domains to a single organization:

• Each domain is monitored independently
• Reports are aggregated in the dashboard
• Alerts can be configured per-domain

Troubleshooting

Verification Failed

Common causes:

• DNS record not yet propagated - wait 15 minutes and retry
• Incorrect TXT value - double-check for typos
• Wrong record location - ensure it's on the root domain

Domain Already Exists

If you see "domain already exists":

• Check if it's in another organization you own
• Contact support if you believe it was added in error

Next Steps

After adding your domain:

1. Configure DMARC - Set up your DMARC policy
2. Set Up Alerts - Get notified about issues
3. Invite Team Members - Collaborate with your team
