Unknown senders
Marketing platforms, payroll tools, ticketing systems, and vendors may all send as your domain without a central inventory.
DMARC, SPF, and DKIM setup service
Make it harder for someone else to send email as your business.
WolfWarden inventories the services sending as your domain, corrects SPF and DKIM, deploys DMARC in stages, and explains what receiving providers are reporting before policy is tightened.
One-time setup and hardening is quoted as a flat-fee engagement. Ongoing report review is optional.
Why projects stall
Publishing a DMARC record is the easy part.
The hard part is finding every legitimate sender, correcting the ones that fail, and tightening policy without breaking invoices, marketing, alerts, or line-of-business systems.
SPF lookup limits
SPF permits only ten DNS-causing mechanisms during evaluation. Layered vendor includes can push a record into permanent error.
DKIM not aligned
A platform may sign mail but use its own domain, which does not necessarily satisfy DMARC alignment for your visible From address.
Policy without observation
Moving to quarantine or reject before reports are understood can interrupt legitimate mail and create an avoidable rollback.
Receivers apply local policy
DMARC publishes the domain owner's requested handling, but each receiving provider ultimately applies its own security policy.
Authentication drifts
New vendors and platform changes appear over time. A working deployment needs a documented way to add senders without weakening the domain.
The engagement
From inventory to enforcement
- Discover every senderReview DNS, tenant configuration, known vendors, and DMARC aggregate data to identify who is using the domain.
- Correct SPF and DKIMRemove conflicting SPF records, control lookup depth, enable DKIM, and align legitimate mail streams.
- Observe in DMARCStart with reporting, classify sources, and confirm that legitimate mail passes before stronger policy is requested.
- Move policy deliberatelyProgress toward quarantine or reject with documented exceptions, rollback criteria, and ongoing change guidance.
What you receive
A working configuration and a handoff you can operate.
The goal is not to create another opaque dashboard. It is to leave the domain in a known state with a documented path for future senders.
- Sender inventoryA list of known platforms and whether each passes SPF, DKIM, and alignment.
- Corrected DNS recordsSPF, DKIM selectors, DMARC policy, reporting addresses, and related records.
- Deployment decisionsWhat was moved to enforcement, what remains in observation, and why.
- Written runbookHow to add a service, what to verify, and where to look when deliverability changes.

Common questions
DMARC setup without oversimplification
Does p=reject guarantee every forged message is rejected?
No. It publishes the domain owner's requested handling for messages that fail DMARC, while the receiving provider retains its own local policy. It materially improves the signal and expected handling without controlling every mailbox provider.
Can this break legitimate email?
Yes, if policy is tightened before legitimate senders are discovered and aligned. That is why the engagement begins with inventory and observation rather than immediate enforcement.
Do I need an expensive DMARC platform?
Not always. The right answer depends on sending complexity, volume, and how often new services are added. WolfWarden can work with provider reports directly or recommend tooling when the operating need justifies it.
Can you help with deliverability too?
Yes, when the issue is related to authentication, alignment, DNS, sending separation, or platform configuration. Reputation and content filtering are receiver-controlled and may require additional evidence or vendor support.
Do you resell Microsoft 365 or Google Workspace licenses?
No. You buy licenses directly from the vendor. WolfWarden configures and documents the tenant without adding license markup or taking ownership of the account.
