ESP Matching is a strategy that improves email deliverability by identifying the email service provider (ESP) of your recipients—such as Gmail, Outlook, or Yahoo—and sending emails from the same ESP. This approach helps ensure emails land in the inbox rather than the spam folder. Follow these three simple steps to identify ESPs and improve your email strategy. And send emails from the matching ESP for better inbox placement and deliverability. Upload your email list, and our tool will detect the ESP for each email and identify any spam protection tools in use. Get a report…from getesp.io
