Buying a Custom Domain for Email Broadcasts

If you want to use Broadcast to send emails, you'll need to set up a custom email domain. It’s a quick process that adds a big layer of protection for your practice.

Why do I need this?

When you send emails from SigmaMD without a custom domain, they go out through a shared system. That’s risky — because if someone else on that system sends too many emails or gets flagged as spam, your messages might also get blocked.

Same is true for using your practice's main domain. If an email is flagged as spam by recipients, you may start facing delivery  issues on your main email.

That could mean important stuff — like invoices, updates, or care reminders — never reaches your patients.

Setting up a custom domain gives your broadcasts their own identity, protecting your practice's email reputation and improving delivery rates.

How to get started

1. Go to Practice Settings → Integrations 

   

2. Click on 'Buy domain'
   You'll be redirected to our partner Ionos, where you can buy your new domain. Once complete, you'll be automatically returned to SigmaMD.
   Tip: you can just add the word "mail" at the end of you current domain. E.g. if your practice's main domain is sigmahealth.com you can try sigmahealthmail.com.
    
3. Wait for verification 
   This usually takes a few minutes to a few hours. Once verified, practice admins will be notified and Broadcast will let you choose email as a delivery option for future messages.
