USE CASE:
Working out what a competitor runs their outbound on
This page is about working out what a competitor runs their outbound on: what your options are for outbound stacks, what each costs, and the one we would use. We are Mamba Labs, we build Apify actors, and Outbound Infrastructure Fingerprint is ours for outbound stacks.
The problem
You are pitching against someone and you can see their emails land, but not what sends them. That matters for two reasons. If you sell into outbound teams, the stack tells you what to say. If you compete with them, the number of sending domains tells you roughly how hard they are pushing.
Traditional Search Tools
- Signing up for their list. The fastest route and the one most people forget. Use a personal address, wait a week, read the headers.
- BuiltWith or Wappalyzer. Strong on website technology, weak on sending infrastructure. They see the marketing site, not the cold email domains, which are deliberately kept off it.
- Read the headers. Get one of their emails, open the raw source, and read the Received chain and the return path. Everything is in there. You need one email, which is the hard part.
