Email marketing is a crucial aspect of running a successful WooCommerce store. However, understanding the ideal email-sending frequency can be challenging, especially when considering the limitations set by various email service providers (ESPs). This article provides a comprehensive guide to optimizing your email sending frequency, ensuring high deliverability and engagement rates while adhering to ESP policies.

Understanding Email Sending Frequency

Email sending frequency refers to the number of emails sent over a specified period. For WooCommerce store owners, this often involves sending newsletters, promotional emails, order confirmations, and abandoned cart reminders. Finding the right balance in your sending frequency can improve customer engagement and avoid issues such as being marked as spam or facing ESP restrictions.

Factors Influencing Email Sending Frequency

  1. Email Service Provider (ESP) Limits: Different ESPs have varying limits on the number of emails you can send per minute, hour, or day. It’s crucial to understand these limits to avoid throttling or blocking.
  2. Subscriber Engagement: High-frequency emails can lead to subscriber fatigue and increased unsubscribe rates. Monitoring open rates, click-through rates, and unsubscribe rates helps in finding the optimal frequency.
  3. Content Relevance: The more relevant and personalized your content, the more frequently you can send emails without annoying your subscribers.

The limit for sending emails from web hosting is comparatively low. If you need to send a large volume of emails from your WooCommerce store, it is best to use an ESP (Email Service Provider) rather than relying on your own web hosting. This approach ensures better deliverability, scalability, and compliance with email-sending best practices.

Best Practices for Email Sending Frequency

  1. Gradual Ramp-Up: When starting with a new ESP or increasing your email volume, do so gradually to avoid triggering spam filters.
  2. Monitor Metrics: Monitor key metrics such as bounce rates, spam complaints, open rates, and click-through rates. Adjust your frequency based on these insights.
  3. Segment Your Audience: Send emails to smaller, targeted segments rather than your entire list at once. This approach not only improves engagement but also helps in managing sending limits.
  4. Use Throttling Features: Some ESPs offer built-in throttling features to help manage sending frequency. Utilize these features to control the rate at which emails are sent automatically.


Finding the ideal email sending frequency for WooCommerce emails is essential for maximizing engagement and maintaining high deliverability rates. By understanding the limits set by your ESP, monitoring key metrics, and following best practices, you can optimize your email marketing strategy effectively. Always remember to start slow, segment your audience, and gradually increase your sending frequency to achieve the best results.

By adhering to these guidelines, WooCommerce store owners can ensure that their email campaigns reach their intended audience without running afoul of ESP restrictions or overwhelming their subscribers.
