Email authentication

Put SPF, DKIM and DMARC on a sound footing.

Your business email, website and marketing tools may all send using your domain. I review those senders, configure authentication for the agreed systems and document the checks so you know what is in place.

The approach

Know what happens next.

  • A review of existing records

    I inspect your DNS and current authentication setup, then identify the sending systems that need to be considered.

  • SPF and DKIM configuration

    I configure or repair the records for the agreed platforms and check their authentication results using live messages.

  • DMARC setup and reporting

    I configure the agreed policy and reporting approach, with enforcement decisions based on the senders and evidence available.

  • Third party sender checks

    I review the approved tools that send for your domain, such as Mailchimp, Klaviyo, HubSpot or SendGrid, within the agreed scope.

  • A record of the configuration

    You receive the records changed, verification results and a plain language explanation of the setup and any next steps.

What helps me scope your project

You do not need every answer before getting in touch. Share what you know, and we can work through the rest together.

  • Which domains need configuration or review?
  • Which provider hosts your business email?
  • Which websites, CRMs and marketing tools send using those domains?
  • Who has access to DNS and the sending platforms?
  • Are DMARC reports or an existing enforcement policy already in place?

Questions about this service

Details before decisions.

The final scope is always confirmed for your specific setup.

Do I need to know every tool that sends email?

A list of known senders is a useful starting point. I review it with you and use the available records and reporting to identify gaps before making policy changes.

Will authentication fix emails going to spam?

It can address authentication problems, but spam placement may also involve reputation, content and sending practices. If messages are already failing, I will help determine whether a deliverability investigation is the right starting point.

Can you work with several domains or providers?

Yes. Share the domains, providers and sending tools involved. I will confirm the scope and quote for that setup before making changes.
