[ Key points ]

  • Choose an unused technical name and preserve existing services.
  • Verify custom domains and branded links separately.
  • Test the selected campaign identity after default-domain changes.

Reserve the right names

Beamery can send recruitment campaigns with customer-domain authentication, but a domain connection is more than a cosmetic sender label. Begin with the recruiting campaign owner, the DNS administrator and a security contact. Record the intended From address, domain, chosen technical subdomain and whether branded tracking is required. Inspect existing DNS at each proposed name before connecting anything.

A familiar name such as careers may already serve a recruitment website. Do not replace that service with a mail-related CNAME. Choose an unused label with the domain owner instead. The name selected for technical routing need not become the visible mailbox address used by recruiters. Beamery's authentication fact sheet explains this distinction and identifies SendGrid as its delivery system.

Complete the custom-domain flow

References: RFC 1034 §3.6.2.

The documented route is Beamery Settings > Email Settings > Custom Domain > Add Your Domain. Supply the domain and subdomain, select Connect Domains, then give the generated records to the DNS administrator. Return to that screen and select Verify after publication. For multiple domains, the domain menu can choose a default. Custom-domain instructions

Copy the generated account values rather than the sample numbered SendGrid hosts in the fact sheet. Its sample illustrates three CNAMEs, including two DKIM selectors; it is not an account-specific prescription. A CNAME delegates resolution at that owner, so inspect any existing record before replacing it. Publish through the authoritative DNS service, which may differ from the registrar.

Beamery also describes generated Inbound Parse values after verification. Treat changes there as a separate routing decision and preserve the current configuration. The existence of this section does not authorize moving the organization's ordinary inbound mailbox MX records.

The documented link workflow is Email Settings > Branded Tracking Links > Add a Branded Links, followed by domain/subdomain entry, Add Link, DNS publication and Verify. Authentication and link branding have distinct verification screens. A working tracking link is not proof that a received message passes DMARC, and a passing signature is not proof that the link destination works.

Original release worksheet: use one row per campaign domain, recording the chosen From identity, generated record owners, default-domain decision, link-branding status and accountable recruiter. Keep account-generated values and screenshots in a private change record. Avoid candidate information in technical test messages.

Test the campaign recipients will receive

References: RFC 9989 §4.4, RFC 6376 §6.

Send a harmless campaign to a controlled mailbox using the intended workflow. Capture the trusted receiving system's authentication results, visible From, envelope sender and DKIM signing domain and selector. Evaluate alignment against the actual From domain. Also follow an approved test link and verify its expected destination and HTTPS behavior without entering real candidate data.

Illustrative scenario: the team authenticates a new recruitment domain but leaves another domain selected as default. A successful DNS check cannot tell you which identity the next campaign uses. The received message and selected campaign settings resolve that ambiguity; adding a second copy of the same DNS records does not.

Maintain an explicit recovery path

If a test fails, pause the affected campaign and restore the last approved domain or link selection. Keep existing valid records until their dependencies are understood. Recheck after changing the default domain, DNS provider or tracking configuration. If policy prohibits sending on the apex domain, engage Beamery's technical team rather than improvising unsupported settings.

This guide reflects documentation reviewed on 8 November 2026. The worksheet and scenario are original operational examples; no Beamery account, DNS update or campaign delivery was executed here.

[ Takeaway ]

Test the selected campaign identity after default-domain changes.

[ By role ]

What this means for you

Choose your role for practical next steps.

IT / Mail Admin

Separate the two configurations

Sender authentication and branded links need their own checks.

Next steps

  1. Publish generated records only.
  2. Verify both screens where used.
  3. Retain actual message identities.

CISO / SecOps

Avoid accidental delegation

A mail CNAME can displace another service.

Next steps

  1. Check existing DNS owners.
  2. Review apex-domain policy.
  3. Exclude candidate data from tests.

Founder / Non-technical

Keep recruiters on the approved identity

Domain defaults affect campaign operations.

Next steps

  1. Name a campaign owner.
  2. Approve the chosen subdomain.
  3. Require a controlled campaign test.

[ FAQs ]

Frequently asked questions

Must the subdomain be careers?

No. Choose an unused name suitable for your organization; Beamery’s common examples are not mandatory values.

Sender Authentication Fact Sheet – Beamery

Will recruiters have to use a subdomain mailbox address?

The fact sheet distinguishes the technical subdomain from the normal visible sending domain. Verify the actual From address in your test.

Sender Authentication Fact Sheet – Beamery

Can I paste the numbered SendGrid sample?

No. Publish the records generated for your own Beamery account and domain.

Sender Authentication Fact Sheet – Beamery

Where do I start domain setup?

Use Settings > Email Settings > Custom Domain > Add Your Domain.

Setting Up Custom Email Domains and Branded Tracking Links – Beamery

Does branded-link verification prove DMARC?

No. Test link behavior and received-message authentication separately.

Setting Up Custom Email Domains and Branded Tracking Links – Beamery

Can I reuse the careers website hostname?

Not without understanding and approving the existing dependency. Prefer a free technical label.

What if apex-domain sending is prohibited?

Beamery says this requires advanced configuration with its technical team. Obtain that supported design first.

Sender Authentication Fact Sheet – Beamery

What should be retested after changing the default domain?

The intended campaign’s actual From, signing identity, envelope identity and any branded test link.

A signature verified using a public key at a selector under the signing domain.

Selector
The DKIM identifier used with the signing domain to locate the public key.

Enterprise provenance

Why top financial institutions and governments retired their email security dashboards.

Traditional email authentication platforms sell you a dashboard and ask your engineers to do the labour. In high-stakes environments, manual oversight means delayed enforcement, configuration drift and unmonitored shadow domains.

EmailAuth is the agentic email provenance platform. Our agents enforce p=reject, keep third-party senders aligned and move your domains to full RFC 9989 compliance, the new DMARC standard,, with human-in-the-loop auditability.
