Sealing

Set up DMARC, SPF and DKIM without breaking your email

It is not pasting a record copied from a tutorial. It is knowing which services send with your domain, authorising them one by one, looking at the reports and only then closing the door. That is what we do for you.

Why a tutorial is not enough

  • The tutorial does not know which services you use

    The SPF you copy authorises Google. Your invoicing program, your newsletter and your website’s contact form are left out and nobody tells you.

  • SPF only allows ten lookups

    Every service you add uses some of that allowance. Go over, and the whole record stops counting, even though it looks well written. We count them by really resolving them.

  • DMARC at none does not protect

    The tutorial ends at p=none. Raising to quarantine and reject without looking at the reports is like changing the lock without knowing who has a key.

This is the sheet you receive

Each record, with its copy button. And a button that checks whether it is already published.

Sealing: we set it up, from end to end

One payment per domain. You do not need to know what a TXT record is: we tell you what to paste and where, and we check that it has gone in properly.

  1. Sender inventory

    You tick which services send with your domain and we read what you already have published.

  2. The record sheet

    A single SPF with everything needed and within the ten lookups, the DKIM steps for each service and your DMARC.

  3. The guide for your panel

    With the name of each record written the way your DNS provider asks for it, and a version to forward to your IT person.

  4. Automatic check

    You press “Check” and we look at your DNS record by record. If something is not there, we tell you which one.

  5. 90 days of delivery receipts

    We read the reports that Gmail, Outlook and the others send every day about your domain, and show them to you in plain language.

  6. The step-up to quarantine and reject

    When the reports say everything of yours passes, we give you the next record. Never before.

  7. The sealing record

    A document with what has been published and the date, for your files or for whoever asks for it.

€129 + VAT, one-off payment per domain. Each additional domain on the same order: €59.

Set-up guarantee. If, when we finish, our checker does not find the SPF, DKIM and DMARC of the services you declared compliant, we carry on until they are or we refund you. It is a guarantee on what can be checked from outside: we do not promise inbox placement, opens or replies.

Guides by DNS provider

Each panel asks for the record name in its own way. These guides link to each one’s official documentation.

Is yours not listed? The sheet comes with a generic guide that works for any panel, and if you get stuck, write to us.
