A good list tells you who could buy from you. A signal tells you who might buy now. That difference is why two campaigns to the same industry can perform so differently.
Signals also solve the hardest part of writing cold email, which is having something true and specific to say in the first line. Here are five that are public, practical and hold up across most B2B markets.
1. Hiring in the right role
Job posts are one of the best signals around, because companies put them in public and they cost real money. A company hiring its third sales rep has a pipeline question. A company hiring its first compliance manager just got serious about compliance. A company hiring for a role your service could replace might be open to another option.
Read the post itself, too. People describe their real problems in job descriptions in surprisingly plain language.
2. A new location or expansion
A second office, a new warehouse, a move into another state. Expansion breaks whatever setup was working: IT, benefits, insurance, logistics, compliance. Local news, press releases and permits will all show you this, often before a salesperson has called.
3. Money coming in
A funding round, a large contract, an acquisition. New money usually comes with a plan to spend it and pressure to do so quickly. It is widely watched, so these people get a lot of email. To stand out, connect it to something specific to their situation and not just "congrats on the raise."
4. A change at the top
A new executive in the area you sell to is one of the strongest signals there is. New leaders review vendors, want early wins and are more open to a change than someone who picked the current provider three years ago. Timing matters here: give them a few weeks to arrive, and reach out within the first few months.
5. A public filing
This one is underused because it takes more work. Government and regulatory filings show who is doing what: building permits, trademark applications, import records, regulatory notices. Which of these matters depends entirely on your market, but most markets have one, and few of your competitors will be looking at it.
How to use a signal without being creepy
Mention what is public and relevant, then move on quickly. "Saw you are opening a Nashville office" is fine, because you are referencing something they announced. Listing details from someone's personal social media is not, and it reads as strange even when it is well meant.
Be honest about the link, too. Do not pretend a signal means more than it does. Saying "companies your size usually hit this problem at the second location" is a fair observation. Saying "I know you are struggling with this" is a guess that sounds like a claim.
When the signal runs out
Not every company on your list will have a fresh event. In that case, don't invent one. An observation about the company itself, such as what they specialize in or who they serve, can do the job. And if there truly is nothing specific to say, it is better to leave that company out of this send than to fake a personal line, because a fake line announces automation in the worst possible way.
We build signals into every list we put together where the data allows it.
