Managing Email Block List
This article guides you through how to configure email delivery reports and manage supplier users affected by email delivery issues.
How the Email Block List works
Supplios places a high priority on reliable communication with your suppliers. If Supplios detects a hard-bounce on an email sent to a supplier user, that user is automatically added to the block list.
While on the block list, a user:
- Cannot be added or invited to new things in the portal (new RFQ invites, new quality issues or other newly assigned workflow tasks)
- Can still log in to the portal
- Will still receive notifications and reminders for things already assigned to them
Block List Report
Supplios can send a daily email report to designated internal users whenever new people are added to the block list.
To configure it, go to More → Company Settings → Email Settings:
- Toggle the report on to enable it, or off to disable it completely.
- Select which Admin or Super Admin users should receive the report.
- If no recipients are selected, all Admins and Super Admins in the account will receive the report (if enabled).

What to do when someone is on the Block List
When you see a user on the Email Block List, work through the options below. Common causes include someone leaving the company, a typo in the email address, or IT problems on the receiving end.
- Check the email address for typos. If you spot an error, correct it directly on the user's profile. Changing the email address will automatically remove the user from the block list - you do not need to clear the hold separately.
- If the address is locked due to a pending invitation, open the contact's details by clicking Open, click Revoke Invitation, and you will then be able to edit the email address.
- If the person has left the company, deactivate them. Important: deactivate directly from the Email Block List - not from the vendor profile (see the note below).
- If you believe the address is correct and the bounce was a temporary issue, click Clear Hold to remove the block and allow emails to resume.
- If the user keeps reappearing on the list after you've cleared the hold, contact the Supplios support team to investigate the underlying delivery issue.

⚠️ Important - deactivating users: If a user on the Email Block List needs to be deactivated, always deactivate them from the Email Block List itself, not from their vendor profile. Deactivating from the vendor profile first will cause an error - the system will report the user as "not found" when you then try to remove them from the block list.
As always, if you have questions about email deliverability or the people on this list, please contact our support team at support@supplios.com, or pop open the in-app Help widget.
