How much mail hard bounce percenatge is allowed

The allowed percentage of hard bounces in email marketing campaigns varies depending on the email service provider (ESP), industry standards, and the specific use case. Here are some general guidelines:

  1. Industry standards:
    • The Email Service Provider Industry Alliance (ESPIA) recommends a hard bounce rate of 5% or less.
    • The Direct Marketing Association (DMA) suggests a hard bounce rate of 3% or less.
  2. Email Service Providers (ESPs):
    • Many ESPs, such as Mailchimp, Constant Contact, and Campaign Monitor, have built-in filters to detect and remove hard bounces. They typically allow a hard bounce rate of 5% to 10% before taking action.
    • Some ESPs, like Sendinblue, have a more stringent policy, allowing only 1% to 2% hard bounce rate before taking action.
  3. Specific use cases:
    • For transactional emails (e.g., password reset, order confirmations), a hard bounce rate of 1% to 2% is generally considered acceptable.
    • For marketing emails, a hard bounce rate of 2% to 5% is often considered acceptable, but it depends on the specific campaign and audience.
