Heymarket allows you to send emails to users individually or in bulk via broadcasts and campaigns. However, not all emails reach their destination; some will be bounced.
Understanding Bounces
A bounced email is one that cannot be delivered to the recipient's email server. When this occurs, the recipient's server sends an automated message called a Non-Delivery Report (NDR) providing more details about the issue.
Bounces are recipient-specific; in a multi-recipient email, some contacts may receive the message while others bounce. It is important to distinguish between the two primary types of bounces:
- Hard Bounce: A permanent delivery failure, often caused by a non-existent email address. Heymarket will mark these recipients as ‘Bounced’ to protect your sending reputation by preventing future attempts.
- Soft Bounce: A temporary delivery failure, such as a full mailbox or a temporary server issue.
Key Considerations
- Unpredictability: Heymarket cannot predict if an email will bounce beforehand.
- ISP Variation: Different internet service providers (ISPs) use their own rating systems and definitions to bounce messages.
Strategies for High Deliverability & Low Unsubscribe Rates
Unsubscribes and bounces negatively impact your deliverability. Proactively managing your lists and content will improve your sender reputation over time.
Here are some things to know.
- Heymarket can't predict if an email will bounce.
- Clean your lists regularly: Remove unengaged, misspelled, fake, or spam email addresses.
- Different internet service providers (ISPs) bounce email messages based on their own rating systems and definitions.
How to decrease unsubscribe rates
Some key strategies to decrease unsubscribe rates include:
- Clean your lists regularly
- Refresh email content and manage preferences page
- Clean your lists regularly
List Cleaning Procedures
- Navigate to the Contacts section
- Filter the contacts by the status ‘Bounced’.
- Bulk delete these contacts to maintain list hygiene.
Unsubscribes negatively impact your deliverability, so proactive list cleaning and suppressing profiles that are unengaged will improve your sender reputation over time.
Monitoring Your Performance: Bounce Rates
Maintaining a low bounce rate is essential for protecting your domain reputation and ensuring emails are not flagged as spam.
| Bounce Rate | Status | Action Needed |
| Under 2% | Acceptable | Standard Healthy Performance |
| 2% - 5% | Warning | May signal issues with data quality or targeting. |
| Over 5% | Critical | Investigate immediately to avoid domain blocking. |
