Outbound Email Security (OnDMARC)

DMARC, SPF, MTA-STS, and BIMI — outbound email authentication done properly

Without proper email authentication, fraudsters can send emails that appear to come from your domain — and recipients have no way to tell the difference. OnDMARC implements the full outbound email security stack and gets you all the way to enforcement, where most businesses stall.

£15.00 + VAT

Per domain, per month (7.50 per additional domain)

Key Features Of This Package

Full authentication stack

DMARC, SPF, DKIM, MTA-STS, and BIMI — all configured, monitored, and maintained. Not just set-and-forget, but actively managed.

Enforcement, not just monitoring

Most DMARC projects stop at monitoring mode. OnDMARC guides you to p=reject — where fraudulent emails are actually blocked, not just reported.

BIMI support

BIMI displays your verified brand logo next to emails in supporting inboxes — giving recipients a visual trust signal that you are who you say you are.

Stop fraudsters sending email as you.

Frequently Asked Questions About Outbound Email Security (OnDMARC)
We have complied a list of questions that are often asked about Outbound Email Security (OnDMARC) and how it can help your business. If you can’t see the answer to a question you have, please contact us today!

DMARC is an email authentication policy that tells receiving mail servers what to do with emails that fail authentication — report them, quarantine them, or reject them. Without it, anyone can send email pretending to be from your domain.

SPF records have a hard limit of 10 DNS lookups. Many businesses exceed this without realising, breaking SPF validation. OnDMARC automatically flattens SPF records to stay within the limit.

Brand Indicators for Message Identification — a standard that displays your verified brand logo next to emails in supporting inboxes (Gmail, Apple Mail, Yahoo). It’s a visual trust signal for recipients.

It depends on your current policy. Most businesses have DMARC in monitoring mode (p=none), which reports spoofing but doesn’t stop it. OnDMARC gets you to p=reject — where fraudulent emails are actually blocked.

Mail Transfer Agent Strict Transport Security — a policy that tells sending servers to only deliver email to your domain over an encrypted TLS connection, preventing downgrade attacks.

The first domain is £15.00 per month. Each additional domain is £7.50 — a 50% discount. Volume discount applies automatically.

Ongoing. Email authentication requires active monitoring — new sending services are added regularly, SPF records drift, and DMARC reporting needs review. OnDMARC manages this continuously.

OnDMARC focuses on outbound authentication — protecting your domain from being spoofed. Inbound email security (catching phishing sent to you) is covered by Avanan in the Cloud Security Packs.

No — we manage it for you. The OnDMARC platform provides the reporting and guided workflow; WDYG handles the technical implementation.
