The NPAI list (No longer lives at the indicated address) groups together invalid or incorrect email addresses that could not receive your campaigns. At Sarbacane, this term also corresponds to what is called a hard bounce, that is to say a permanently invalid email address.
It is important to note that Sarbacane Contacts identifies these addresses only after your first send. If you are migrating from another emailing solution, we therefore recommend that you import your NPAI or bounce list before your first send in order to avoid sending campaigns to addresses that are already invalid.
The NPAI list is specific to each account and is automatically enriched after each campaign sent via Sarbacane Campaigns.
Access the NPAI list
To view your NPAI list in Sarbacane Contacts:
Log in to your Sarbacane account
Open the Contacts application
In the left-hand side menu, click on Contact lists
Select the NPAI list tab
You will then be able to view all addresses identified as invalid.
Manage your NPAI list
From this tab, several actions are possible:
View the information related to each address (original campaign, date added, import source, etc.)
Add new NPAI addresses via a file, manual entry, or copy-paste
Export the complete list or a selection of addresses in Excel format
View statistics, in particular the distribution of NPAI by domain name
⚠️ It is not recommended to clear the NPAI list, unless explicitly requested by our team, as it helps maintain the quality of your mailings.
