Email authentication records are the technical backbone of email security, yet millions of businesses operate without them, leaving their domains vulnerable to spoofing and their legitimate emails at risk of landing in spam. WebElev8 implements SPF, DKIM, and DMARC records correctly, improving your email deliverability and protecting your brand from being used by spammers and scammers.

Why Choose Our DMARC, SPF & DKIM Setup Service?

We deliver measurable results that grow your business

Prevent Domain Spoofing

DMARC, SPF, and DKIM together prevent criminals from sending emails that appear to come from your domain, protecting your brand reputation and your customers.

Improve Email Deliverability

Properly authenticated emails are far more likely to reach recipients' inboxes. Gmail and Microsoft now require strong authentication for bulk senders.

Meet Google & Microsoft Requirements

Google and Microsoft have mandated authentication standards for email senders. Our setup ensures your domain meets these requirements and avoids deliverability issues.

Protect Your Brand

Criminals use unprotected domains to send scam emails to your clients, suppliers, and prospects. DMARC enforcement puts a stop to this and protects your reputation.

Visibility into Email Abuse

DMARC reporting gives you detailed visibility into who is sending email using your domain, revealing any unauthorised sources and attempted abuse.

Compliance Alignment

Implementing email authentication supports Cyber Essentials, NCSC guidance, and GDPR compliance obligations related to protecting personal data in communications.

What's Included

Everything you need in one comprehensive package

SPF Record Configuration

We create or correct your SPF (Sender Policy Framework) record, specifying every mail server authorised to send email on behalf of your domain.

DKIM Key Generation & Setup

We generate DKIM cryptographic key pairs, publish the public key in your DNS, and configure your mail server to sign outbound messages with the private key.

DMARC Policy Implementation

We create your DMARC record starting with a monitoring-only policy, then progress to quarantine and reject policies as your authentication confidence grows.

DMARC Report Analysis

We set up DMARC aggregate (RUA) and forensic (RUF) report collection and provide regular analysis of the reports to identify authentication issues and spoofing attempts.

Third-Party Sender Configuration

Many businesses send email through third-party services like Mailchimp, HubSpot, or Salesforce. We ensure all legitimate sending sources are properly authorised in your SPF and DKIM.

Subdomain Protection

We extend authentication protection to your subdomains, preventing criminals from using subdomain variations of your domain for spoofing attacks.

MTA-STS & TLS-RPT

We implement MTA-STS (Mail Transfer Agent Strict Transport Security) to enforce encrypted email transport and TLS-RPT for reporting on TLS-related failures.

Policy Enforcement Progression

We guide you through the process from p=none (monitoring) to p=quarantine to p=reject, moving at a pace that ensures no legitimate emails are affected.

Our Process

A proven, structured approach to delivering results

Email Flow Discovery

We audit all the services sending email on behalf of your domain, including your mail server, marketing platforms, CRM, and transactional email services, to map your full email sending infrastructure.

SPF & DKIM Implementation

We create or update your SPF record to cover all legitimate senders and set up DKIM signing on your mail server and any third-party sending services.

DMARC Monitoring Deployment

We implement a DMARC record in monitoring mode (p=none) with reporting configured, allowing us to collect data on all email sent from your domain before enforcing any policies.

Analysis & Policy Enforcement

We analyse your DMARC reports, resolve any authentication failures from legitimate sources, and progressively tighten your DMARC policy to quarantine and ultimately reject unauthorised senders.

Frequently Asked Questions

What are SPF, DKIM, and DMARC in plain English?

SPF is a list in your DNS that says which servers are allowed to send email for your domain. DKIM adds a digital signature to your emails that proves they genuinely came from you. DMARC tells receiving mail servers what to do when an email fails SPF or DKIM checks. Together, they form a comprehensive email authentication framework.

Will setting up DMARC break my email?

A DMARC record in monitoring mode (p=none) does not affect email delivery at all. Problems only arise if you move to an enforcement policy (quarantine or reject) while legitimate sending sources are still failing authentication. Our careful, phased approach ensures we identify and fix all authentication issues before enforcing any policy that could affect delivery.

Do I need this if I already use Google Workspace or Microsoft 365?

Yes. While Google and Microsoft provide DKIM signing for your email, they do not set up SPF or DMARC for you. Without these, your domain may still be spoofable and your emails may face deliverability challenges. We see many businesses on Google Workspace and Microsoft 365 with incomplete or absent email authentication.

How long does it take to see results?

DNS changes propagate within 24–48 hours. DMARC reports start arriving within days of implementation and give you visibility into your email authentication posture almost immediately. Moving from monitoring to full enforcement typically takes four to eight weeks, depending on the complexity of your email sending infrastructure.

What are DMARC reports and what do they tell me?

DMARC aggregate reports are XML files sent daily by major email providers (Gmail, Outlook, Yahoo, etc.) showing all email claimed to be from your domain, whether it passed authentication, and where it was sent from. These reports are invaluable for identifying spoofing attempts and discovering misconfigured sending sources.
