Proton Mail uses advanced spam filtering driven by machine learning to sort all incoming emails. You can create your own spam, block, and allow lists to complement or override Proton’s general spam filtering.
To better serve and protect the high-profile businesses and organizations that rely on Proton for Business, we also support spam, block, and allow lists for organizations.
Organization administrators (admins) can create filter lists that apply to all members of the organization.
Here are some use cases for spam, block, and allow lists:
- Spam: Your organization regularly receives junk mail from an email address, and you want to send future messages from this sender to your members’ spam folders.
- Block: One of your members reported a phishing attack, and you want to immediately block the sender to protect your organization.
- Allow: You want to start an email marketing campaign in your organization and ensure all emails from the sender will arrive in your members’ inboxes.

View organization filter lists
To view all existing filters and add new ones for your organization, log in to your administrator Proton Mail account at mail.proton.me(new window) and click Settings → All settings → Organization → Organization filters → Spam, block, and allow lists.
The filter lists for organizations are split into three tabs, Spam, Block, and Allow:
- Spam: These emails will arrive in the spam folder of your organization members, unless overridden by user filters.
- Block: These emails will be dropped and not delivered to your organization members.
- Allow: These emails will arrive in the inbox of your organization members, unless overridden by user filters.
In terms of priority, users’ spam and allow lists can override the organization’s spam and allow lists. However, the organization’s block list has the highest priority and can’t be overridden. Emails from senders in the organization’s block list won’t be delivered to any users.
