How it works

Send mail

A short mail from the company address to check@conbool.com is enough, no sign-up required.

Analysis runs

Conbool checks authentication, transport encryption, reputation and the domain configuration.

Receive scorecard

The result comes back as a clear scorecard with an overall grade and prioritised actions.

What is checked

Authentication

SPF, DKIM and DMARC determine whether mail in the domain name is forgery-resistant.

Transport

TLS, MTA-STS, TLS-RPT and DANE secure encrypted mail transport.

Reputation

Reverse DNS and blocklists show how the domain is seen by recipients.

Encryption

S/MIME and PGP protect confidential content end to end.

The analysis is based on the check mail sent and publicly queryable DNS records. The sender address is stored to provide the scorecard and for possible follow-up contact by Conbool. An objection is possible at any time at info@conbool.com. Privacy policy
