Keep emails out of
spam.

Are your quotes, invoices or newsletters ending up in spam? With the free email check, we find out where it goes wrong. We check how your domain proves your email is genuine, test where it lands at Gmail and Outlook and review your list and your content. You receive a clear report with the causes and fixes in order of priority. That way your email reaches the people who are waiting for it again.

Since November 2025, Gmail has been rejecting more mail that breaks the sending rules. Outlook has done so for large senders since May 2025. That is why the check covers 7 fixed points, from your domain to your unsubscribe link.

1. DOMAIN

Prove who you are

Mail providers first check whether an email really comes from your domain. They do this with three authentication checks in your domain settings: SPF, DKIM and DMARC. Together they tell providers who may email on your behalf and what happens to forged email. We check whether all three are correct, including for services that email on your behalf.

Introduction and your email traffic 🎯

In a first call, Dominic, your dedicated point of contact, finds out which recipients are getting your email in their spam.

Together we choose which addresses and mailings we test.

Access to take a look πŸ”‘

We can read your domain settings from the outside. For your sending system, we ask for read access.

In this phase everything stays as it is. We look and measure.

Domain audited πŸ”

We check every authentication record of your domain, including for services that email on your behalf.

Think of your newsletter, your webshop or your accounting software.

Test email at the major providers πŸ“¬

You send an email the way your customers receive it, to test addresses we manage.

For each provider, we read whether it reaches the inbox or lands somewhere else.

List and unsubscribing 🧹

We look at how your list was built and how many emails bounce.

We also test whether one-click unsubscribe works and is processed quickly.

Content and sender βœ‰οΈ

We read your email through the eyes of a filter, from sender name to last link.

We list anything that could raise suspicion.

Report and call πŸ“‹

You receive a report with the causes in order of priority and the fix for each point.

Dominic walks you through it, then you choose how to proceed.

Fix and keep measuring πŸ“ˆ

If you leave the fix to us, we adjust the settings and ramp up your sending volume step by step.

After that, we measure every month how your email lands, often as part of an ongoing partnership.

Frequently asked questions

Frequently asked questions about keeping emails out of spam (FAQ)

  • It is often down to your domain settings. If an authentication check is missing, or a service emails on your behalf outside those checks, the provider doubts your email. An old list or lots of spam complaints also cost reputation.

    The free check shows which cause applies to you. That way you first tackle what sends the most email to spam and the rest after that.
  • The check is free and without obligation. Afterwards you have a report with the causes in order of priority, with the fix for each point. Dominic walks you through the outcome.

    Then you choose. You pick up the points yourself, hand them to your own IT partner or leave the fix to us. If you choose the latter, you receive a clear proposal with planning and price in advance.
  • Anyone emailing Gmail addresses needs at least one authentication check, an encrypted connection and few spam complaints. If you send around 5,000 emails a day, all three checks and one-click unsubscribe are mandatory.

    Since May 2025, Outlook has set similar requirements for large senders. Since November 2025, Gmail has been rejecting more mail that breaks the rules.
