How do I use buying signals (job changes, funding, hiring) to time my outreach?
The short answer
The best cold email is not the cleverest one, it is the one that arrives the week something changed: a champion switched jobs, the company raised money, or they posted a hiring ad for the problem you solve. Signal-based outbound uses AI to watch for these triggers across thousands of accounts and puts the right prospect on your list at the right moment. Job changes are the highest-converting signal and are most actionable within the first two weeks.
A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
