Signal-based cold email outreach
Trigger hyper-personalized cold emails based on real-time intent signals like job changes, funding rounds, or LinkedIn activity instead of generic spray-and-pray.
Why this can grow a startup
Generic cold email is dying because inboxes are flooded. Signal-based outreach cuts through because it references something the recipient just did or experienced, making the message feel relevant and timely rather than random. Using separate domains for outreach, warming up accounts for 14+ days, and capping volume per account keeps deliverability high. The key is surgical targeting over volume.

When to use it
Use this when Email is relevant to 0-100, 100-1K and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
