Who this is for

This product is intended for people who work with email lists in CSV format and want to improve deliverability by sending from the right ESP. It may be useful for teams that need a quick way to identify ESP patterns before running email campaigns.

The available evidence does not include pricing, privacy, security, or broader file-format details, so those points should be checked separately before use.
