This is why we love using tools like** HubSpot,** as they can give you complete insights into why your emails have bounced. 1. What we do is we go to our HubSpot account and navigate to Marketing > Email. 2. Click the name of your email that included any contacts who bounced. 3. Click the Recipients tab. 4. In the left sidebar menu, click Bounced. 5. ** ****Voila! ** So what are the types of bounces? **[Hard bounce](https://knowledge.hubspot.com/email/what-is-the-difference-between-a-hard-bounce-and-a-soft-bounce?_ga=2.127830989.1902655052.1673899531-2053802173.1645678000#hard-bounce):** usually indicates a permanent error but can also be caused by a strict email security filter. To protect your email sender's reputation, HubSpot [excludes these contacts](https://knowledge.hubspot.com/articles/kcs_article/email/analyze-your-marketing-email-campaign-performance#not-sent) from future emails. **[Soft bounce](https://knowledge.hubspot.com/email/what-is-the-difference-between-a-hard-bounce-and-a-soft-bounce?_ga=2.127830989.1902655052.1673899531-2053802173.1645678000#soft-bounce):** indicates a temporary problem with the recipients' server, or another temporary technical problem. Contacts who soft bounce are eligible to receive future emails from you. **Pending bounce:** caused by a temporary technical issue with either the sending or receiving email server. HubSpot continues to try sending the email for up to 72 hours. If the message isn't delivered during that time, it becomes a [soft bounce](https://knowledge.hubspot.com/email/what-is-the-difference-between-a-hard-bounce-and-a-soft-bounce?_ga=2.127830989.1902655052.1673899531-2053802173.1645678000#soft-bounce). **Global bounce:** a hard bounce for a permanent reason across three or more HubSpot accounts. Permanent bounces include [unknown user](https://knowledge.hubspot.com/email/what-is-the-difference-between-a-hard-bounce-and-a-soft-bounce?_ga=2.127830989.1902655052.1673899531-2053802173.1645678000#hard-bounce-errors-and-recommendations) and [mailbox full](https://knowledge.hubspot.com/email/what-is-the-difference-between-a-hard-bounce-and-a-soft-bounce?_ga=2.127830989.1902655052.1673899531-2053802173.1645678000#hard-bounce-errors-and-recommendations). Global bounces are [dropped](https://knowledge.hubspot.com/articles/kcs_article/email/analyze-your-marketing-email-campaign-performance#not-sent) from future emails across all HubSpot accounts. # All of HubSpot's Hubs.
