methodology / Email & Communications / #76

Email provider class (Workspace / 365 / Zoho / self-hosted / shared)

live factor #76 · Email & Communications · scoring impl: implemented · weight 0.7%

What we measure

We classify your email provider into a quality tier. Google Workspace and Microsoft 365 are professional grade. Bargain-host shared mail is a deliverability and security risk.

How to improve your score

Migrate to Google Workspace, Microsoft 365, Fastmail, or Zoho. Avoid running mail through your hosting provider's built-in mail unless it's a managed-WP host with explicit mail support.

Data source

Data source for this factor is not yet documented.

Implementation notes

Already collected. Could expand to detect Brevo, Mailgun, etc. as transactional senders separately from primary mailbox provider.

Scoring

Scoring formulas are versioned with the methodology. The current method (v1.1.0) maps raw measurements to pass, warn, fail. Factor weights determine how much each contributes to the composite — see the methodology index for the full table.
