Insights

This panel provides a summary of your generated inbox report.

The information on this panel gives a simplified overview of all the analyzed data. Click any of the mentioned information boxes to be taken directly to that panel of the report.

Authentication

The authentication panel provides information regarding DKIM, SPF, and DMARC fields. These are the protocols of email authentication.

• SPF (Sender Policy Framework)

SPF verifies whether the sending mail server is authorized to send emails on behalf of the domain by checking the sender’s IP against the domain’s DNS records.

• DKIM (DomainKeys Identified Mail)

DKIM uses cryptographic signatures to confirm that the email was sent by the claimed domain and that its content was not altered during transit.

• DMARC (Domain-based Message Authentication, Reporting & Conformance)

DMARC builds on SPF and DKIM to define how receiving servers should handle authentication failures and provides reporting to help domain owners monitor and prevent spoofing.

Placement

Placement tells you where your email actually lands after it is delivered and will show the inbox, spam % rate. Click on the "VIEW" option on the respective mail providers to see more details.

In this Gmail placement example, Inbox is 100% and the inbox breakdown placement is under Updates 100%. Spam is 0%.

So, the email will be delivered on the updates section for the gmail.

In this Outlook placement example, Inbox 0% and Spam 100%. So, the email will be delivered on the Spam/Junk folder for the outlook emails.

The outlook placement also shows the SCL, BCL, PCL scoring.

• SCL (Spam Confidence Level): Outlook’s score showing how likely an email is spam.
• BCL (Bulk Complaint Level): Outlook’s measure of how often users mark similar bulk emails as spam.
• PCL (Phishing Confidence Level): Outlook’s assessment of how likely an email is a phishing attempt.

Spam Scoring

Spam scoring ranks the likelihood of an email being labeled as spam.

SpamAssassin is spam scoring engine. When you click "VIEW" on SpamAssassin, you can view the scores for various providers.

Link Validation

Shows information about the links present in your email, the image structure and whether the links inside your email are safe, reachable, trustworthy and if they could trigger spam filters or security warnings that hurt inbox placement.

Image Validation

Shows the information about the images present in your email, whether the images inside your email are safe, accessible, properly hosted, and spam-filter friendly so they don’t hurt inbox placement or break visually for recipients.

Blacklists

This panel offers information regarding any blacklists your domain(s) or IP address(es) are currently on.

All of these panels consist of technical analysis of the content and placement of your email and your sender domain characteristics.
