[ 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
- Publish generated records only.
- Verify both screens where used.
- Retain actual message identities.
CISO / SecOps
Avoid accidental delegation
A mail CNAME can displace another service.
Next steps
- Check existing DNS owners.
- Review apex-domain policy.
- Exclude candidate data from tests.
Founder / Non-technical
Keep recruiters on the approved identity
Domain defaults affect campaign operations.
Next steps
- Name a campaign owner.
- Approve the chosen subdomain.
- 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.
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.
Can I paste the numbered SendGrid sample?
No. Publish the records generated for your own Beamery account and domain.
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.

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.
What should be retested after changing the default domain?
The intended campaign’s actual From, signing identity, envelope identity and any branded test link.

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.
