Yes, you keep your current email provider. DMARC Engine is a DNS-based service, not an email host, so nothing about where your mail is sent or received has to change.
Why it works with any provider
Email authentication lives in DNS, not in your mailbox. DMARC, SPF, DKIM and BIMI are all published as records on your domain. They describe and authorise the systems that send mail as your domain; they do not move or store your email.
That means we work alongside whatever you already use:
- Google Workspace and Microsoft 365
- Self-hosted or ISP mail
- Marketing and transactional senders (e.g. your CRM, helpdesk or newsletter tool)
We identify every legitimate source sending on your behalf, make sure each one is properly authenticated with SPF and DKIM, and align it under DMARC. Your provider keeps doing exactly what it does today.
What we actually change
We manage your delegated DNS records, DMARC, SPF, MTA-STS and BIMI, and ingest your RUA reports so we can stage enforcement safely from p=none to p=reject. DKIM keys usually stay pointed at your provider's selectors, which is exactly how they should be.
At no point do we touch your MX records or relay your mail. There is no migration and no risk of an email outage.
