It would be incredibly beneficial if we could offer a feature that enables users to set customizable email-sending limits per day on a domain level, depending on the subscription package they have opted for. This would provide an enhanced level of control and flexibility for managing email volumes based on specific user requirements.
Furthermore, integrating an anti-abuse mechanism within this feature would be invaluable in maintaining the integrity of our platform. By setting a customizable rate failure threshold, we could effectively deter and prevent abuse. For instance, a basic entry-level plan might allow for 100 outbound emails per hour with a 5% failure rate.
This combination of features would not only improve user experience but also protect our platform from misuse and maintain a high standard of service quality for all users.
