No, these features will remain functional for your domain even if your subscription expires, ensuring there is no immediate downtime. However, you will lose the ability to manage or modify these settings through the platform until your subscription is renewed.
If you choose not to renew your subscription, it's essential to take proactive steps to prevent potential disruptions. Managed DMARC and EasySPF rely on dynamic records provided by the system, but the features themselves will no longer be accessible after expiration. To avoid future issues, you should deactivate these features and revert to manual record management before your subscription ends.
By doing so, your domain will rely on static, manually configured records instead of the system-generated dynamic ones, ensuring continuity without relying on the expired service.
