Wix and Squarespace domain email DNS checker
Check the public DNS records that matter when email on a Wix or Squarespace domain is not receiving or authenticating correctly.
Wix and Squarespace are site builders that often also manage a domain's DNS. Neither one hosts mailboxes itself - business email is usually a Google Workspace add-on or a separate mailbox provider.
Use this page to confirm which dashboard actually controls DNS for the domain, then check that the mailbox provider's records are published there.
DNS records to check first
| Record | What to check | Safe note |
|---|---|---|
| Active DNS host | Confirm whether the domain's nameservers point at Wix, Squarespace, or an external registrar or DNS host. A domain connected by pointing keeps its DNS at the original host. | Edit email records in whichever dashboard the nameservers make active; changes anywhere else never reach public DNS. |
| MX | If the mailbox is Google Workspace sold through Wix or Squarespace, confirm the MX setup that Google Admin shows for the account - many newer setups use smtp.google.com. | Builder dashboards often add Google MX records automatically; confirm what public DNS returns instead of assuming the automation ran. |
| SPF | If Google Workspace sends mail for the domain, the SPF record commonly includes _spf.google.com; other mailbox providers have their own include. | Keep one SPF record that merges every real sender, including any marketing or form-sending tools. |
| DKIM | Generate DKIM in the mailbox provider's admin console - for Google Workspace, in Google Admin - and publish the exact value through the active DNS dashboard. | Do not invent DKIM selectors or keys. Wix and Squarespace cannot generate DKIM for a mailbox provider. |
| DMARC | Add a DMARC record once SPF and DKIM are confirmed so receivers know what to do with failing mail. | Start at p=none and review reports before tightening, especially when several tools send as the domain. |
Common mistakes
- Editing DNS at the registrar while the nameservers point at Wix or Squarespace, or editing in the builder while DNS still lives at the registrar.
- Assuming buying a domain through a site builder includes a mailbox - email is a separate subscription.
- Leaving placeholder or default records in place after adding Google Workspace MX records.
- Publishing a second SPF record for the mailbox provider instead of merging it into the existing record.
Boundaries
Domain Email Doctor checks public DNS records only and does not access a Wix, Squarespace, or Google account.
Domain subscriptions, Google Workspace add-on billing, and DNS automation stay inside the builder dashboards.
Provider-generated verification and DKIM values must come from the mailbox provider's admin console, and a passing DNS check does not guarantee inbox placement.
