Frequency
The rate at which emails are sent to recipients.
Frequency refers to how often emails are sent to subscribers. Striking the right balance is key: sending too frequently can overwhelm recipients and lead to unsubscribes, while infrequent emails might result in disengagement. Optimal frequency depends on audience behavior, content type, and campaign goals. Monitoring engagement metrics helps determine the best email cadence. Many ESPs offer tools to optimize email frequency based on recipient activity.
