When a hard bounce occurs, HubSpot automatically removes the contact from your email list. This helps to protect your sender reputation and ensure that your emails are delivered to the inbox.
HubSpot has three types of email bounces: hard bounces, soft bounces, and pending bounces.
- Hard bounces are permanent errors that prevent an email from being delivered. Common hard bounce reasons include:
- Invalid email address
- Mailbox full
- Account disabled
- Spam filter
When a hard bounce occurs, HubSpot automatically removes the contact from your email list. This helps to protect your sender reputation and ensure that your emails are delivered to the inbox.
- Soft bounces are temporary errors that prevent an email from being delivered. Common soft bounce reasons include:
- Server overload
- Out of office
- Temporary network outage
When a soft bounce occurs, HubSpot will retry delivering the email for up to 72 hours. If the email is still not delivered after 72 hours, it will be marked as a hard bounce.
- Pending bounces are caused by a temporary technical issue with either the sending or receiving email server. HubSpot will continue to try sending the email for up to 72 hours. If the message isn't delivered during that time, it becomes a soft bounce.
It's important to monitor your bounce rates and take steps to address any issues that may be affecting your deliverability. High bounce rates can damage your sender reputation and make it more difficult for your emails to reach the inbox.
Here are some tips for improving your email deliverability:
- Use a double opt-in process. This will help to ensure that only interested subscribers are added to your email list.
- Keep your email list clean. Remove any contacts who have unsubscribed, bounced, or been inactive for an extended period of time.
- Use a reputable email service provider. A good email service provider will have a strong deliverability infrastructure and can help you to troubleshoot any delivery issues.
- Follow best practices for email marketing. This includes using clear and concise subject lines, avoiding spammy language, and including an unsubscribe link in all of your emails.
By following these tips, you can improve your email deliverability and ensure that your emails reach the inbox.
