550 5.7.26 - Gmail SMTP rejection is live

Gmail now rejects unauthenticated email. Are your clients' domains compliant?

Since November 2025, mail that fails authentication does not go to spam - it bounces. Check any client domain's DMARC, SPF and DKIM in seconds, free.

Free. No signup. Checks DMARC, SPF, DKIM and MX in seconds.

Built for MSPs and web agencies managing 10-50 client domains.

Why now

Three enforcement waves, and they keep coming

Email authentication stopped being optional. Each wave breaks delivery for another slice of your client base.

Feb 2024

Google and Yahoo

Bulk senders (5,000+/day) must have SPF, DKIM and a DMARC record. Non-compliant mail started landing in spam.

May 2025

Microsoft

Outlook and Hotmail enforce SPF, DKIM and DMARC for senders over 5,000 messages/day.

Nov 2025

Gmail

Escalated from spam-foldering to SMTP-level rejection. Non-compliant mail now bounces with error 550 5.7.26 and never reaches the inbox.

It is an audit item now, too

PCI DSS v4.0 (mandatory since March 2025) expects anti-spoofing controls like DMARC. 68.7% of domains worldwide still have no effective DMARC protection.

Monitoring that your clients actually see value from

Dashboards get ignored three months after enforcement passes. Alerts and client-facing reports do not. That is what we are building.

One weekly digest for every client domain

Instead of 30 dashboards nobody opens, one Monday email: which domains passed, which broke, what changed.

New-sender and shadow-IT alerts

A client signs up for a new email tool and starts failing DMARC? You know before their invoices bounce.

White-label monthly PDF reports

Client-facing reports with your logo, ready to attach to your monthly review. Proof of the work you already do.

12-month retention on every plan

A full year of aggregate report history for audits, PCI DSS evidence and incident forensics. Not a paid add-on.
