GetESP

GetESP is an email deliverability analysis platform designed to help teams choose and optimize the right Email Service Provider (ESP) for their campaigns. By allowing users to upload actual email content and test it across multiple providers and filters, GetESP provides data-driven insights into how messages are treated before they reach recipients. Its primary purpose is to reduce guesswork in ESP selection and configuration, enabling more consistent inbox placement and higher overall deliverability performance.

The platform analyzes emails across 30+ ESPs and 15+ spam filters, giving a comprehensive view of how different infrastructures impact deliverability. Users can identify which ESPs are more likely to land in the inbox, promotions, or spam for specific content types, audiences, or sending patterns. GetESP highlights deliverability risks, such as content triggers or configuration issues, and helps compare performance across providers using consistent, testable criteria. The tool’s interface focuses on clear, actionable reporting rather than opaque scores, making it easier to interpret and apply findings.
