Email Compliance
Email is essential to everyday business communication, but it is also one of the most common routes for phishing, impersonation and brand abuse. Email compliance helps ensure your domain is properly protected, authorised senders are verified, and suspicious emails are handled correctly.
At TwentyFour IT Services, we help businesses strengthen domain trust, reduce impersonation risk and maintain compliance through the correct implementation and management of SPF, DKIM and DMARC.

What is Email Compliance?
In short; email compliance is the process of making sure your business email domain is properly authenticated, monitored and protected against misuse.
This includes configuring key email authentication controls such as SPF, DKIM and DMARC.
SPF allows your business to define which mail servers are authorised to send emails on behalf of your domain. DKIM adds a digital signature to outgoing emails so that receiving servers can verify that the message has not been tampered with. DMARC ties SPF and DKIM together, giving receiving mail servers clear instructions on what to do when an email fails authentication.
These controls help protect your domain from spoofing, phishing and impersonation, while also supporting better visibility over who is sending emails using your business identity.
Email compliance is not a one-time setup. It requires careful configuration, regular monitoring and ongoing management as your business adds new systems, marketing platforms, finance tools, CRM platforms, third-party services and cloud applications.
Why is Email Compliance Important?
Without the right email authentication controls in place, cyber criminals may be able to send emails that appear to come from your business domain. This can be used to target your customers, suppliers, employees or wider network with phishing emails, fraudulent payment requests, malicious links or fake documents.
The impact can be significant. A spoofed email can damage customer trust, disrupt business operations, put sensitive data at risk and harm your brand reputation.
Email compliance helps reduce this risk by making it much harder for unauthorised senders to successfully impersonate your domain. It also provides your business with greater visibility over the systems and services sending emails on your behalf, helping you identify misconfigurations, unknown senders and potential threats.
It is also increasingly important for deliverability. Major email providers are placing greater emphasis on authenticated email, meaning that businesses without the correct records and alignment may find that legitimate emails are more likely to be rejected, quarantined or marked as spam.
What Does the Email Compliance Process Involve?
Achieving strong email compliance starts with understanding your current email environment. This means reviewing your domain records, identifying the systems that legitimately send emails on your behalf, and checking whether SPF, DKIM and DMARC are configured correctly.
The first stage is visibility. DMARC can be introduced in a monitoring mode, allowing your business to collect reports without affecting email delivery. This helps identify which platforms are sending emails from your domain and whether they are passing or failing authentication.
From there, your email records can be reviewed and refined. SPF records need to include authorised senders without becoming overly permissive or exceeding technical limits. DKIM should be configured across the platforms that send email on behalf of your business. DMARC should then be aligned correctly so that receiving servers can trust legitimate email and take action against messages that fail authentication.
Once your legitimate email sources are identified and configured, your DMARC policy can be strengthened over time. This usually moves from monitoring, to quarantine, and eventually to reject, helping block unauthorised emails that attempt to misuse your domain.
However, this must be managed carefully. Moving too quickly can risk disrupting genuine business email. Moving too slowly can leave your domain exposed. The right approach is structured, monitored and aligned with how your business actually uses email.
How Can TwentyFour IT Services Help You Achieve Email Compliance?
At TwentyFour IT Services, we work with businesses to review, implement and manage email compliance in a way that strengthens security without disrupting day-to-day communication.
We begin by assessing your current domain configuration, reviewing SPF, DKIM and DMARC records, and identifying any gaps that may leave your business exposed to spoofing or impersonation. We also help identify authorised and unauthorised sending sources, including Microsoft 365, CRM systems, marketing platforms, finance tools, website forms and third-party applications.
From there, we develop a practical roadmap to improve your email authentication posture. This includes correcting misconfigured records, enabling DKIM where required, implementing DMARC reporting, and helping your business move towards stronger enforcement policies safely.
Our team also supports the ongoing management of your email compliance. As your business adopts new platforms, changes suppliers or introduces new communication tools, your email authentication setup must continue to evolve. We help keep your records accurate, your reporting visible and your domain protected.
