Email bounces happen when your email fails to reach its recipient. But not all bounces are the same. Here’s a quick breakdown:
- Hard Bounces: Permanent delivery failures caused by invalid email addresses or non-existent domains. Action: Remove these addresses immediately.
- Soft Bounces: Temporary issues like full inboxes or server problems. Action: Monitor and retry within 24-72 hours.
Quick Comparison
| Characteristic | Hard Bounces | Soft Bounces |
|---|---|---|
| Nature | Permanent failure | Temporary failure |
| Common Causes | Invalid addresses, non-existent domains | Full inboxes, server errors |
| Action Needed | Remove from list | Monitor and retry |
| Impact | Strong negative effect | Minimal unless repeated |
Managing bounces effectively protects your sender reputation and ensures better email deliverability. Use email verification tools to keep your lists clean and campaigns successful.
Hard Bounces and Soft Bounces: What Sets Them Apart
Understanding Hard Bounces
Hard bounces happen when an email can’t be delivered due to permanent issues like invalid email addresses or domains that don’t exist [3]. These failures can hurt your sender reputation and make it harder to deliver emails in the future [2][4].
Understanding Soft Bounces
Soft bounces are temporary delivery issues caused by things like full inboxes or server errors. They often resolve themselves [1][3]. A single soft bounce isn’t a big deal, but if the same address keeps bouncing, it could signal a bigger problem that needs attention [3].
Hard vs. Soft Bounces: A Quick Comparison
Here’s a breakdown of the main differences between hard and soft bounces:
| Characteristic | Hard Bounces | Soft Bounces |
|---|---|---|
| Nature | Permanent failure | Temporary failure |
| Common Causes | Invalid addresses, non-existent domains, blocked accounts | Full inboxes, server errors, large attachments |
| Required Action | Remove from the list immediately | Monitor and retry |
| Impact on Deliverability | Strong negative effect | Minimal impact unless it happens repeatedly |
| Retry Potential | None – failure is permanent | Retry within a short timeframe |
| Resolution Timeline | Needs immediate action | Typically resolves within 24-72 hours |
Hard bounces demand quick action, like removing invalid addresses from your list. Soft bounces, on the other hand, require tracking and retrying. Using email verification tools can help you spot potential bounce risks early, keeping your email deliverability strong and your domain reputation intact.
How to Handle Email Bounces
Managing Hard Bounces
Hard bounces need to be addressed right away to maintain your sender reputation [1][3]. Follow these steps to handle them effectively:
- Set Up Automated Removal: Use tools provided by your email service provider to automatically flag and remove hard-bounced addresses. Keep a record of these addresses to avoid adding them back by mistake.
- Audit Your Email Lists Regularly: Review your email lists every quarter to spot hard bounce trends and take action before they affect your reputation [3][4].
While hard bounces require immediate attention, soft bounces call for a more measured approach.
Managing Soft Bounces
Soft bounces should be monitored for patterns. If an address soft bounces three times in a row, treat it as a hard bounce and remove it from your list [2][3].
Here’s how you can handle soft bounces more effectively:
- Adjust email sizes to meet server requirements.
- Keep an eye on bounce trends by email provider.
- Retry sending emails within 24 to 72 hours.

How Bounces Affect Email Deliverability
Managing bounces effectively is essential to ensure your emails consistently reach your audience. Both hard and soft bounces can harm your sender reputation and campaign performance, but they do so in different ways.
The Impact of Hard Bounces
Hard bounces are a major issue for email deliverability. These occur when emails are sent to invalid addresses, signaling poor list management to Email Service Providers (ESPs). High hard bounce rates can lead to serious consequences, such as:
- Emails being sent straight to spam folders
- Delays in delivery
- Blocking of your IP address
- A lower sender score
- Risk of being blacklisted
"Hard bounces are a clear indication that an email address is invalid or does not exist, and should be removed from your list immediately to protect your sender reputation." [1]
The Impact of Soft Bounces
Soft bounces are temporary but can still cause problems if not addressed. They may delay delivery, waste resources on retries, and potentially turn into hard bounces, which can harm your reputation further [1][3]. Keep an eye on soft bounces to identify potential issues, such as:
- Problems with your sending reputation
- Email content triggering spam filters
- Strict delivery policies on the recipient’s server
Monitoring bounce rates is key to maintaining good deliverability. Tools like Bouncebuster can help identify invalid addresses early, reducing both hard and soft bounces. By understanding the reasons behind bounces and addressing them promptly, you can protect your sender reputation and improve your email campaigns. We’ll dive deeper into ways to reduce bounces in the next section.
Tips to Reduce Email Bounces
Understanding how bounces impact email deliverability is only half the battle. Let’s dive into actionable strategies to cut down on both hard and soft bounces in your campaigns.
Regularly Check Your Email Lists
Keeping your email list up-to-date is key to avoiding bounces and protecting your sender reputation. In fact, regular email verification can lower bounce rates by as much as 98% [1]. Here are some ways to keep your list clean:
- Use real-time validation tools during signups and verify your list every quarter for accuracy.
- Be proactive – clean your list before you notice a drop in engagement metrics.
While this helps eliminate invalid addresses, it’s equally important to ensure your email content doesn’t trigger server rejections.
Optimize Your Email Content
Well-optimized emails not only engage your audience but also avoid soft bounces caused by server restrictions. Many email servers enforce size limits, with some as low as 10MB [2]. Stick to these guidelines:
| Content Element | Suggested Limit |
|---|---|
| Total Email Size | Under 10MB |
| Text-to-Image Ratio | 80:20 |
Monitor and Segment Your Email Lists
Effective email list management goes beyond just cleaning – it’s about understanding your audience. Here’s how to reduce bounces through better targeting:
- Study bounce patterns and adjust your targeting based on engagement.
- Segment your audience by engagement levels to send tailored campaigns.
- Adjust sending frequency to match each segment’s preferences.
- Remove subscribers who consistently show no engagement.
Tools like Bouncebuster can simplify this process by automating real-time email verification and integrating with popular email marketing platforms. Combining segmentation with verification tools ensures your lists stay clean, while your campaigns remain effective.
Conclusion: Final Thoughts on Managing Bounces
Let’s wrap up by refining how you handle email bounces to keep your campaigns running smoothly.
Hard bounces are permanent failures, meaning those email addresses should be removed immediately. On the other hand, soft bounces are temporary issues that could resolve themselves over time [1][3]. Knowing this difference is crucial for safeguarding your sender reputation and ensuring your emails reach their audience [2].
To stay on top of things, address both types of bounces systematically. Remove hard bounces within 24 hours. For soft bounces, monitor them for up to 72 hours. If the same address soft bounces three times, treat it as a hard bounce. This step-by-step process helps you maintain strong deliverability rates and protects your domain’s reputation.
Here’s how to manage bounces effectively:
- Validate your email lists regularly to avoid sending to invalid addresses.
- Track bounce patterns to identify recurring issues.
- Fine-tune your content to reduce server-related soft bounces.
- Leverage real-time verification tools to catch problems before they escalate.
Real-time email verification tools, like Bouncebuster, can be a game-changer. They help you keep your email list clean and prevent invalid addresses from damaging your sender reputation. By integrating these tools with the strategies discussed earlier, you can boost your email deliverability significantly.
Bounce management isn’t just about removing bad addresses. It’s an ongoing effort that involves:
- Keeping your email list clean and validated
- Optimizing your email content
- Monitoring patterns in bounce data
- Using preventive verification techniques
Taking these proactive steps will help your email campaigns achieve consistent deliverability while protecting your sender reputation over the long haul.
FAQs
What is a soft bounce back?

Should I remove hard bounces from my email list?
Yes, hard bounces should be removed right away because they indicate a permanent delivery failure [3]. Leaving hard bounces on your list can harm your sender reputation and even get you blacklisted [2].
To keep your email list in good shape, remove hard bounces within 24 hours, verify new subscribers, and use double opt-in to avoid invalid addresses [4].
