GetESP
Improve email deliverability with ESP matching
About
GetESP.io is a web-based tool designed to help users identify the Email Service Provider (ESP) and any associated spam protection tools for email addresses within an uploaded CSV file. The service aims to improve email deliverability by allowing users to segment their email lists based on ESPs (e.g., Gmail, Outlook, Yahoo) and send emails from matching providers. This strategy is intended to increase inbox placement, enhance email authentication, and speed up delivery. The tool provides instant analysis, a downloadable report, and supports a continuously updated list of ESPs and spam protection services like Proofpoint, Mimecast, and Barracuda Networks. It is currently free to use.
