Notis

Review signup IPs without leaving Slack

When your team shares a signup IP in Slack, Notis can run an Ip2proxy check and return the classification for review.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Check Proxy Status of an IP

Tool to check if an IP address is a proxy. Use after obtaining an IP to detect proxy, VPN, or Tor status.

Why this helps

A founder reviewing new signups may lose focus opening separate tools for each suspicious IP.

  • Keep signup review and IP context close together.
  • Avoid repeating manual lookups for each flagged signup.
  • Give the team a consistent starting point for follow-up.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Ip2proxy to Notis once in the portal.
  • 2Create an automation in the portal or ask Notis conversationally.
  • 3Describe that Notis should check IP addresses shared with signup-review context and report proxy, VPN, or Tor status.
  • 4Select the Slack channel message trigger, choose a run-report channel, and test with one real signup IP.

Questions about this workflow

Can the automation decide whether to reject a signup?

This workflow checks IP status. The team can use the result as context for its own review.

Can I use it in a dedicated channel?

Yes. Choose the relevant Slack channel message trigger when creating the automation.
