Introduction
We completely understand why many clinics want patient emails and appointment reminders to come from their own domain (e.g., `yourclinic.com`). It feels more personal and on-brand.
However, TrackStat does not support sending emails from custom domains. All outbound emails are sent from `patienthealthcenters.org` on your behalf. This is a deliberate design choice that protects your deliverability, security, and compliance while keeping things simple for you.
Below we explain exactly why this matters and why we handle email sending centrally.
How TrackStat Email Delivery Works
TrackStat has the capability to send:
Appointment confirmation & reminder emails
Drip campaign emails
Blast campaign emails
Marketing campaign emails
Canned Reply emails
…all from the verified domain `patienthealthcenters.org`.
You still see your clinic name in the From line of the email (e.g., “Your Clinic Name"), but the actual sending domain remains `patienthealthcenters.org`. This ensures every email reaches inboxes reliably.
Why Custom Domains Are Not Supported: The Technical Reality
Email authentication is far more complex than most people realize. Modern email providers (Gmail, Outlook, Yahoo, etc.) use strict rules to fight spam and phishing. If these rules aren’t configured perfectly, your emails get blocked, land in spam, or damage your domain’s reputation.
Here are the three main authentication standards we manage for you:
1. SPF (Sender Policy Framework)
Tells the world exactly which mail servers are allowed to send emails for a domain.
If the wrong server sends mail, the email fails SPF and is often rejected.
2. DKIM (DomainKeys Identified Mail)
Adds a digital signature to every email so receivers can verify the message wasn’t altered in transit.
Requires a special DNS record (a long cryptographic key) that must be kept up-to-date.
3. DMARC (Domain-based Message Authentication, Reporting & Conformance)
The “boss” policy that tells receivers what to do when SPF or DKIM fails (quarantine, reject, or none).
Misconfiguring DMARC can instantly tank your deliverability.
Managing these for thousands of unique clinic domains would be extremely complex. A single typo in a DNS record, an expired certificate, or a forgotten update could:
Cause your emails to bounce
Get your domain blacklisted
Trigger spam filters across the entire internet
Expose you to phishing risks (spammers love impersonating real clinic domains)
That’s why we handle one single, professionally managed domain (`patienthealthcenters.org`) at enterprise scale. Our team monitors authentication 24/7, rotates keys, responds to DMARC reports, and maintains pristine sender reputation - so your messages consistently land in the inbox.
What You Can Do Instead
While custom domains aren’t available, you can still strengthen your brand:
Add your logo to email templates
Include your clinic’s contact info and website in every email
