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.
