What are custom domains?
Adding a custom domain will allow you to use your own domain for hosting and sending Pods. This means instead of a url like “pods.trumpet.app/…” it would be “pods.example.com/…”
Before you start
Custom domains are an Elite plan feature — the option only appears once that’s enabled on your account.
You’ll need a subdomain on a domain your company already owns (e.g.
pods.yourcompany.com). Your IT team, or whoever manages your DNS, usually creates this.That subdomain must not already be used for something else.
You cannot use trumpet’s own domains (e.g.
trumpet.app) as your custom domain.If your company runs automated security scans on websites, exclude this domain from those scans — scans can trigger protections and temporarily break access.
If you own “example.com”, your subdomain could be “pods.example.com”, “hubs.example.com”, “collab.example.com”, “yourproject.example.com” — or whatever takes your fancy!
How to set up your custom domain
In trumpet, open Settings → Custom Domain. If you don’t see this menu item, custom domains likely aren’t enabled on your plan yet.
Enter the subdomain and main domain (e.g. subdomain
pods+ domainyourcompany.com).Click Verify domain. trumpet will show the DNS records you need to add.
Ask your IT team (or log into your DNS provider — GoDaddy, Cloudflare, etc.) to add the DNS records exactly as shown in trumpet. You can copy each value from the table in the settings screen.
Wait for DNS to update — this can take up to 48 hours, though it’s often faster.
When the records are in place, click Activate domain in trumpet. Once it shows as verified, your live Pod links will use the new domain.
If something goes wrong
What if I am getting an Invalid configuration error?
This means the domain or subdomain doesn’t exist on any DNS server yet.
If the domain doesn’t exist, you may need to purchase it (e.g. via GoDaddy).
If you already own the domain, your IT team may need to add a CNAME record for the subdomain first.
You can use whatsmydns.net to check whether your domain and subdomain exist on DNS.
What if I am getting a Pending verification error?
The domain exists on a DNS server, but it isn’t yet verified for use with trumpet. Add the TXT record shown on the Custom Domain settings screen — this is sometimes needed when the domain is registered elsewhere. You can remove that TXT record once verification is complete.
What if I have a wildcard subdomain already set?
After setting the custom domain in trumpet, you will also need to add the below record to your DNS records:
Type: CNAME
Name: <NAME_OF_YOUR_SUBDOMAIN>
Value: 38703aa7fe1237c7.vercel-dns-016.com
Still stuck after ~48 hours?
If your records are in place and it’s still not working after 48 hours, contact trumpet support or post in #tech-questions for deeper DNS help.
Optional: custom email domain
On the same settings page, you can also set up email so invites and notifications come from your company domain — this helps avoid spam filters. It’s a separate section with its own DNS records to add. See Custom Email Domain for details.
Changing your domain later
Remove the existing custom domain in settings first, then add the new one.
Note: any old Pod links that used the previous domain will stop working.
