Start with the domain. Add the rest when you’re ready.

Three steps, flat prices, no contracts, no per-ticket fees. Every client starts with the domain registration and setup. Monitoring and important senders are your call — add them at registration or any time after.

Domain registration, setup & "whitelisting"*

The complete foundation: sender profile, domain setup, SPF, DKIM, and DMARC published correctly, provider registrations and submissions where programs exist, our "whitelisting" process at Google, Microsoft, and the rest, and a documented monitoring baseline. Nobody else does this part.*

Important-sender coverage

For billing, owner, support, and other addresses that can never miss: domain association, provider status setup, authentication, and "whitelisting" for the individual sender, plus its own monitoring.

$19 one-time
per email
+ $4/mo or $39/yr

Every additional domain gets the same treatment at the same rates: $149 setup plus its own monitoring at $199/yr or $19/mo.

Sender packages (volume pricing)

Setup and first-year annual monitoring for batches of important senders, added to the domain service. Above 50 senders is custom.

Third-party senders (add-on)

Most businesses also send email through outside systems that use their domain: booking and scheduling tools, CRMs, invoicing and payment platforms, marketing and newsletter services, and help desks. Those systems send from their own infrastructure, so they need their own authentication published in your DNS. Without it, mail sent on your behalf can be flagged as spam even when your own mailbox is set up perfectly.

Add-on

Third-Party Sender Authentication

We cover any outside system that sends as your domain. We identify how it sends, obtain the vendor's DKIM and SPF values, publish them alongside your existing records, and verify that messages authenticate and pass. Includes ongoing monitoring, so a vendor change never silently breaks your deliverability.

$99 one-time
per system
+ $4/mo or $39/yr

Priced per sending system. A single vendor that sends from several addresses counts once. Volume pricing is available for agencies and multi-system setups.

A quick example

A plumbing company registers one domain with annual monitoring, and adds their billing and owner addresses as senders:

  • Domain registration, setup & "whitelisting": $149 one-time
  • Domain monitoring, annual: $199/year
  • 2 sender setups: 2 × $19 = $38 one-time
  • 2 sender monitoring, annual: 2 × $39 = $78/year

Due today: $464. Then $277/year. The register page totals this for you automatically as you choose.

How payment works: You build your plan on the register page and pay right there through Stripe, one of the world’s largest payment processors. Your card details go to Stripe’s secure checkout, never to this website. Annual plans renew automatically with an email notice beforehand; monthly plans bill once a month. Manage your plan, payment method, and invoices anytime in your client dashboard. We never store card numbers.

Every plan includes the honest promise: we make your sending identity complete, authenticated, registered where programs exist, and continuously monitored. We do not promise guaranteed inbox placement, because no legitimate service can. See the FAQ for details.

* Third-party SaaS support is available as an add-on. If an outside system sends email as your domain, its authentication is not included in the standard domain setup. See Third-Party Sender Authentication above.
