Email deliverability: SPF, DKIM and DMARC done properly.

If your quotes, invoices or Klaviyo campaigns are landing in spam, the cause is almost always DNS. DarkForge AI configures and audits SPF, DKIM and DMARC across every domain and sending service you use, migrates Google Workspace and DNS without losing a message, and keeps inbox placement monitored. Fixed price, usually finished inside a week, for businesses in Orange County and anywhere in the United States.

What goes wrong

Gmail and Microsoft now reject mail that is not authenticated.

Since 2024, bulk senders to Gmail and Yahoo must pass SPF and DKIM and publish a DMARC policy, and Microsoft followed. Most small businesses have a half-configured SPF record, a DKIM key for one service but not the others, and no DMARC at all. The symptoms are quiet: replies stop coming, campaigns underperform, and nobody can say why.

  • SPFOne record that covers every service that sends as you: Google Workspace, Klaviyo, Shopify, Stripe, your CRM, your helpdesk. Under the ten-lookup limit, with nothing forgotten.
  • DKIMSigning keys generated and published for each sender, rotated on a schedule, and verified end to end.
  • DMARCA policy that starts in monitoring, with reports collected and read, then moved to quarantine and reject once every legitimate sender passes.
  • BIMI, MTA-STS and TLS reportingThe second-tier records that raise trust with mailbox providers, added where they help.
  • Workspace and DNS migrationsMoving mail from a legacy host to Google Workspace, or DNS between providers, with a cutover plan and a rollback for every record.
  • MonitoringScheduled audits of every domain you own, with alerts that reach a person when a record drifts.

How we work

Audit, fix, verify, monitor.

We built a command-line auditor that pulls live DNS for every domain in a portfolio, validates SPF, DKIM and DMARC syntax, scores deliverability and writes a report in under five seconds per domain. It runs before every fix and on a schedule after. Twelve domains in our own portfolio hold 100% inbox placement on it.

Who this is for.

E-commerce brands

Klaviyo, Shopify and Stripe all send as your domain. One misconfigured record drags every flow into promotions or spam.

Agencies and brokerages

Quotes, proposals and follow-ups that never arrive cost deals. A lead-generation site we rebuilt for an Orange County brokerage pairs a spam-proof form with hardened sending.

Clinics and wellness operators

Appointment reminders and prescription communications have to land, and have to be sent from infrastructure you control.

Businesses moving providers

Migrations to Google Workspace, new DNS hosts or new domains are where records break. We plan the cutover to the record.

Multi-domain portfolios

Holding companies and operators with several brands get one audit, one fix and one monitor across all of them.

Anyone who just got a bounce

"550 5.7.26 unauthenticated email is not accepted" is a DNS problem with a fixed-price fix.

Deliverability questions.

How long does a deliverability fix take?
Most single-domain setups are audited, fixed and verified inside a week. DMARC moves from monitoring to enforcement over the following two to four weeks as reports confirm every legitimate sender passes.
Will fixing DNS break anything?
Not when it is planned. Every change is staged with a rollback, DMARC starts in monitoring mode, and we verify each sending service before tightening policy.
Do you need access to my domain registrar?
We need access to wherever your DNS is hosted (Cloudflare, GoDaddy, Namecheap, Porkbun, Squarespace and others). Access is granted to accounts in your name and removed at handover if you prefer.
Can you fix Klaviyo or Shopify email specifically?
Yes. Dedicated sending domains, DKIM for each platform, and a DMARC policy that covers them all are the standard fix. See Shopify development if the store itself needs work.
What does it cost?
A fixed price quoted after a free automated audit of your domain. Portfolios of several domains are priced as one engagement.
