Audience Preferences: Understanding what your audience wants and expects is crucial. Segment your email list and gather feedback to tailor your approach. Type of Content: The nature of your content can significantly impact how often you should send emails. Informational newsletters may require less frequent sends than promotional emails. Industry Standards: Research the norms within your industry to gauge an appropriate frequency. For example, media companies may send daily updates, while B2B companies may opt for a monthly digest. Engagement Metrics: Monitor your open rates, click-through rates, and unsubscribe rates. If engagement drops, it may be a sign that you're emailing too often.
