Meet SendLint

SendLint checks marketing emails against the copy and creative a team has approved before a campaign is sent. Users provide the email and its reference materials, and the service examines copy, links, images, accessibility, metadata, rendering, and brand requirements. Findings show where the built email differs from the source material so reviewers and developers can work from specific evidence.

The platform tracks issues across review rounds, records approvals and waivers, and can produce a verification certificate tied to the final HTML. Agencies and internal marketing teams can use it to review multiple versions or languages, recheck corrections, and keep a record of what was inspected before sign-off.
