Because Public Notices are a project-level feature, there isn't currently a way to send one out to all vendors registered with your Bonfire portal.
If you need to send an announcement out to all registered vendors, you can:
- Export a list of all vendors from the Vendors Dashboard.
- Open the export in the appropriate software (e.g., Excel) and copy all email addresses.
- Paste the email addresses into your preferred email client (preferably using the BCC field) and send out a mass email.
