What VP Pulse Monitors
DMARC Policy Check
Instantly check whether your domain has a DMARC record and what policy level it enforces. Move from p=none (monitoring only) to p=reject (full protection) with guidance on each step.
SPF Strength Analysis
VP Pulse checks your SPF record for the critical -all qualifier (hard fail) vs ~all (soft fail). Domains with ~all provide significantly weaker protection against email spoofing.
DKIM Selector Enumeration
VP Pulse checks common DKIM selectors to verify that your domain's email is cryptographically signed. Missing DKIM means DMARC alignment will fail for DKIM-authenticated mail flows.
Email Deliverability Context
Understand how Google, Yahoo, and Microsoft DMARC requirements affect your email deliverability. Domains with p=none or no DMARC face increasing deliverability penalties from major providers.
Business email compromise (BEC) is the most financially damaging cybercrime category targeting UK businesses. Attackers send email spoofing your domain to deceive employees, clients, and suppliers into transferring funds or sharing credentials. DMARC, SPF, and DKIM are the proven technical controls that prevent this β and VP Pulse checks all three for free.
The UK Email Security Gap
A significant proportion of UK business domains have either no DMARC record or p=none β providing no actual protection against spoofing. This is particularly common in the SMB sector, where email security configuration is often overlooked in favour of user-facing features. VP Pulse analysis of UK domains shows substantial room for improvement across legal, accounting, and professional services sectors.
Since 2024, Google and Yahoo have required DMARC for bulk email senders. Microsoft followed with similar requirements in 2025. Without DMARC, your marketing and transactional email faces increasing deliverability penalties β ending up in spam or rejected outright by major providers.
Frequently Asked Questions
- How do I check if my domain has DMARC?
- Use VP Pulse's free domain scan at pulse.vpnetworks.co.uk/scan. Enter your domain and the scan returns your DMARC policy, SPF qualifier, and DKIM coverage in seconds.
- What DMARC policy should I use?
- Start with p=none to monitor email flows without affecting delivery. After 4β8 weeks, move to p=quarantine, then p=reject. P=reject provides maximum protection but requires SPF and DKIM to be fully configured first.
- Does DMARC affect email I send through MailChimp or HubSpot?
- Yes β marketing tools that send email on your domain's behalf must be configured with DKIM signing and their sending IPs added to your SPF record. Check their documentation for instructions specific to your email platform.
