Understanding Email Frequency by Industry: How Often Should You Contact Your Subscribers?

March 7, 2025

Email marketing is one of the most powerful tools for businesses to build relationships, boost engagement, and drive conversions. However, a common question among marketers is:

How often should I send an email campaign?

Too many emails can overwhelm subscribers, leading to unsubscribes, while too few can make your brand easy to forget. Finding the right balance is key.
Additionally, factors like the best time to send an email campaign and the impact of frequency of emails on open rates play a crucial role in your success. Let’s explore industry benchmarks and strategies to help you optimize your email campaigns.

Maximizing Value in Email Marketing

Retail brands can improve efficiency by focusing on engaged subscribers.
Media companies can maintain high-frequency emails while optimizing list management.
SaaS businesses can manage large databases without overspending on inactive contacts.

  • Media companies with high-frequency emails must aggressively manage lists to control costs.
  • SaaS businesses with large databases might struggle with email marketing expenses despite lower sending volumes.
