InboxReady: Email Deliverability Audit is a free Chrome add-on designed to enhance email marketing effectiveness by ensuring messages reach inboxes rather than spam folders. This tool provides a thorough audit of critical email authentication protocols including SPF, DKIM, DMARC, and BIMI, allowing users to identify potential issues and security risks with a single click. With features such as syntax error detection and policy enforcement checks, it caters to both marketers and developers looking to optimize their email strategies.

The latest version introduces a Deliverability Score, providing users with a clear rating of domain health on a scale from 0 to 100. Additionally, it can automatically detect the marketing technology stack in use, identifying platforms such as Klaviyo, Shopify, and Mailchimp among others. Users can also generate professional reports, making it easy to share findings with team members or clients. This tool is particularly beneficial for email marketers, agency owners, and IT managers.
