Default Email Domain

Overview

When sending emails through RedFlag, your location will use a default email domain unless you choose to configure a custom domain. This ensures that messages are deliverable and compliant with email authentication standards, even without additional setup.

Default Email Domain

RedFlag uses the following default domain to send emails if a custom domain has not been configured:

• From Email Address: no-reply@redflaghub.com
• From Name: Defaults to “RedFlag Notification from [Location Name]” (can be adjusted under the Email Template section)
• Authentication Status: ✅ Authenticated
  The default domain is fully authenticated using industry-standard DNS records (SPF, DKIM, DMARC), ensuring high deliverability and reduced spam risk.

When is the Default Domain Used?

• When no custom domain has been added under More > Setup > Email Domains
• When a previously added custom domain has been deleted
• For any new locations, RedFlag defaults to no-reply@redflaghub.com until a custom domain is added and authenticated

🛡️ Note: Using the default domain allows you to begin sending emails immediately without DNS configuration or IT involvement.

Benefits of the Default Domain

• No Setup Required – Emails are ready to send out of the box
• High Deliverability – RedFlag manages all DNS authentication
• Spam Protection – Messages are sent from a domain trusted by major email providers

Limitations of the Default Domain

• You cannot use your organization's domain name in the sender address
• Recipients may not immediately recognize the sender as your brand
• Limited branding control compared to a custom domain

How to Revert Back to the Default Domain

If you've previously set up a custom domain and want to return to using RedFlag's default:

• Navigate to More > Setup > Email Domains
• Click the Trash Icon next to your custom domain
• Confirm the deletion — your account will immediately revert to:
  • From Address: no-reply@redflaghub.com
  • Status: Authenticated

🛡️ Note: If you want to update the default sending address no-reply@redflaghub.com to use your organization’s domain, please refer to Add Custom Email Domain.

IP address

To ensure reliable delivery of RedFlag email messages, your IT team may need to whitelist the sending IP address associated with our email servers: 167.89.17.161. 

Why Whitelisting the IP Address is Important

• Some email systems or firewalls may block or filter emails from unknown or unauthenticated sources.
• Whitelisting helps prevent RedFlag emails from being marked as spam or rejected altogether.
• This is especially important if you’re using a custom email domain, as your email system may apply stricter rules for messages that appear to come from your own domain but are sent through an external service.

When Whitelisting is Recommended

• You're using a custom domain for sending RedFlag emails.
• Your organization has strict email filtering or security policies.
• Recipients are reporting not receiving email notifications, especially internally.
• We provide the sending IP address in the Email Domains setup area, so your IT team can easily access and add it to your email allowlist or firewall rules.
