Understanding and Managing Email Bounce Suspension

Email bounces refer to emails that were not successfully delivered to the recipient's inbox. There are two main types of bounces:

• Hard Bounces: These occur when the email address is invalid or does not exist.
• Soft Bounces: These are temporary delivery failures due to issues like a full mailbox or the recipient's server being down.

Email bounces 指的是未能成功投递到收件者收件匣的电子邮件。主要分为两种类型：

• Hard Bounces：当电子邮件地址无效或不存在时发生。
• Soft Bounces：属于暂时性的投递失败，常见原因包括信箱已满或收件者的伺服器暂时无法使用。

Causes of an Account Suspension

If your bounce rate exceeds the industry standard (typically below 5%), your account could be suspended. A high bounce rate often signals poor sending practices, including emailing invalid addresses or being flagged as spam. Maintaining a bounce rate between 0-3% is generally considered optimal to ensure healthy email deliverability.

若 bounce rate 超过业界标准（通常应低于 5%），账户可能会被暂停。过高的 bounce rate 往往代表寄送方式不佳，例如寄送到无效地址，或邮件被标记为垃圾邮件。将 bounce rate 控制在 0–3% 之间通常被视为最佳做法，可确保电子邮件的正常送达率。

How to Fix the Hard Bounce and Reactivate Your Account

If your account is suspended due to a high bounce rate, take the following actions to resolve the issue:

1. Review Recent Email Activities: Inspect recent campaigns, workflows, and bulk messages for potential problems.
2. Pause All Outgoing Emails: Temporarily stop all workflows, campaigns, and bulk messages to prevent further issues.
3. Validate Email Addresses: Ensure all emails are directed to verified, active email addresses.
4. Provide Proof of Opt-In: Respond to the suspension notice with evidence of opt-in, including examples of unsubscribe links in your messages.
