Which option allows you to exceed your comms limit for an operational email?

The option that allows you to exceed your communication limit for an operational email is to uncheck the "block operational email." When this setting is disabled, it allows operational emails to be sent even when the overall communication volume has hit the designated limit imposed on marketing emails. This is essential as operational emails, which include important transactional messages or alerts, should still reach recipients regardless of overall communication constraints.

Other options involve either enabling a setting that could help with operational emails or strategies like resetting limits or upgrading plans, but they do not specifically relate to enabling the send of operational emails beyond the established comms limit as directly as unchecking the block option does.
