What to do with contacts that have a "Bounced" status
When an email cannot be delivered to a recipient, depending on the reason, the contact is automatically marked as “Bounced” in your list.
1. How to identify "bounced" contacts?
These contacts are easy to identify by the "Stop" icon associated with their profile.
You can also find them using a filter in your contact list:
You can also search for bounced contacts in your list by using the Contact Status (1) filter.
When you click the Stop icon (2), you can get an overview of why the contact is marked as bounced.
This allows you to understand the cause of the problem and adjust your actions accordingly (invalid address, inbox problem, server rejection, etc.).

Keep in mind that the more errors you accumulate when sending your emails, the more it can harm your deliverability.
A deliverability problem occurs when your emails:
- End up in the spam folder
- or are not delivered at all
instead of reaching your recipients' inbox.
2. The "bounced" status and its consequences
To protect your sender reputation, contacts in the "Bounced" status in systeme.io no longer receive emails.
This measure helps preserve the quality of your deliverability and prevents invalid or problematic addresses from impacting your future campaigns.
3. The best practice to adopt
It is highly recommended to:
- Regularly check your list of "Bounced" contacts
- Delete these addresses from your database
This helps maintain a clean, up-to-date list and improves the overall performance of your email sends.
Notes:
- When a contact marks one of your emails as spam in their inbox, they will automatically be moved to the "Bounced" status in systeme.io.
- If you are sure a contact was marked as bounced by mistake, we recommend that you contact us so we can reactivate this contact and remove them from your bounced contacts list.
