Why change your workspace subdomain
Every workspace gets a default address like yourteam.essential.support, chosen when you signed up. If that slug no longer fits — a rename, a typo, or you just want it to match your company name more closely — you can change it yourself, with live availability checking before you commit.
Change your subdomain
- Click the gear icon in the top bar to open Settings.
- In the left-hand navigation, click Branding, then click the Custom domain sub-tab.
- If you don’t currently have a custom domain connected, a Workspace subdomain section appears at the top of the page, above the custom-domain tools. (If you do have a custom domain connected, this section is hidden — see the note below.)
- The field shows your current slug, with “.essential.support” fixed to its right as a suffix.
- Type your new slug. As you type, only lowercase letters, numbers, and hyphens are kept — anything else you type is stripped automatically — up to a maximum of 63 characters.
- About 400ms after you stop typing, availability is checked live and reported just below the field: “Checking availability…” while the check runs, then either “<newslug>.essential.support is available” with a checkmark, or an inline error such as “That subdomain is already taken.”
- Read the warning shown on the page before saving: your current address stops working immediately and becomes available for anyone else to claim; any existing links to it — notification emails, the embedded widget, and SSO — will break.
- Once the field reports “available” and your typed slug differs from your current one, Save subdomain becomes clickable. Click it.
- A confirmation reads “Subdomain changed. Taking you to <newhost> to sign in again…”, and after about 2 seconds your browser is redirected to the new address automatically.
- Sign in again at the new address. Sessions are tied to the exact host you’re on, so your previous session doesn’t carry over to the new one.
Subdomain naming rules
- 1–63 characters: lowercase letters, numbers, and hyphens only, with no leading or trailing hyphen.
- Internationalized/punycode subdomains (any slug starting “xn--“) aren’t allowed.
- Subdomains ending in “-sbx” are reserved — that suffix is used internally for the Integration Sandbox.
- A short list of reserved system words, and a further list of blocked words, can’t be used either; you’ll see a generic “Please choose a different subdomain.” if you hit one of those.
Notes and edge cases
- The Workspace subdomain field only appears when you have no custom domain connected. If you’ve already connected a custom domain (see Connect a custom domain), it becomes your canonical (actively serving) address and this field disappears — remove the custom domain first if you need to change the underlying subdomain.
- Subdomain changes are rate-limited to 10 per hour, per workspace.
- If you use the Integration Sandbox, changing your subdomain deletes your existing sandbox sub-workspace; a fresh one is created automatically the next time you open the sandbox.
- Typing your current slug back into the field shows “This is your current subdomain.” and the Save button stays disabled — it’s treated as a no-op, not an error.
