You’ll notice two new sub-Labels under “GMass Reports”: “Bounces” and “Replies”. Based on italy phone number resource your particular email campaigns, you may also notice the sub-Labels “Blocks”, “Delays”, and “Over Limit”.
Here are the details on each reply management category:

Bounces: Bounce notifications indicating that an email address you sent to is invalid. These are removed from your Inbox and placed under the Bounces Label. Additionally, the bounced address is added to your account’s bounce list, and further attempts to send to this email address will be suppressed by GMass. This means that you no longer have to manually extract bounces from your Gmail account. (If you click the regular Gmail “Send” button, however, you can still send to bounced addresses.) You also have granular control over your account’s bounce list. See this post on how to manage your account’s bounce list or have your account ignore bounces.
