What is the difference between hot, warm and cold leads?
The difference is how much evidence you have that the person is looking now. All three fit your buyer profile. A hot lead has recently said or done something that shows they need what you sell. A warm lead has shown interest in you, or has had a change that often comes before buying. A cold lead fits on paper and has shown nothing yet. Someone who doesn't fit isn't a lead at any temperature.
| Label | Fit | What you've seen | Our time window | Next step |
|---|---|---|---|---|
| Hot | Matches your buyer | A stated need: asked for a recommendation, compared tools, asked for an alternative, replied with interest | Last 14 days | Reply the same day |
| Warm | Matches your buyer | Attention or timing: engaged with you, followed, subscribed, new role, hiring, funding | Last 60 days | A message that names the signal, within a week |
| Cold | Matches your buyer | Nothing visible | None | No pitch; a short, useful first message or nothing |
| Not a lead | Doesn't match | Anything | None | Remove from the list |
The windows are our working rule, not an industry standard. Pick your own and write them down, so two people on your team label the same lead the same way.
Hot, warm and cold: 13 common signals, labelled
By our labels, most signals sold as hot are warm: they show attention, not need. Here is how we would label common ones:
| Signal | Label | Why |
|---|---|---|
| Posts "can anyone recommend a tool for [your category]?" | Hot | A stated need, in public, now |
| Asks for an alternative to your competitor | Hot | Already buying the category and unhappy |
| Replies to your message with "tell me more" | Hot | Direct interest in you |
| Comments on your post about the problem you solve | Warm | Attention on the problem, no stated need |
| Only likes your post | Weak warm | A reaction costs one tap |
| Follows you or your company page | Warm | Attention, no need stated |
| Subscribes to your newsletter | Warm | Opted in to hear from you |
| Started as head of the team you sell to in the last 90 days | Warm | A change in who decides |
| Company hiring for the work you automate | Warm | The work is growing |
| Company announced funding | Warm | Budget, not need |
| Engaged with a competitor's post | Warm | Interest in the category |
| Said "not now, try next quarter" | Cold until that date | Asked you to wait |
| Fits your profile, no activity | Cold | No evidence of timing |
A real example. In June 2025 one r/Entrepreneur poster asked for a tool to detect leads with "really hot signals" and listed six: a comment on their post or a competitor's, a new follower, a newsletter sign-up, a new connection with a competitor, someone launching a marketing campaign, and a funding announcement. By our labels, none of the six is a stated need, so at most they are warm. The difference matters because the message changes: a warm lead needs a reason to talk, and a hot lead needs an answer. Our guide to using job postings as buying signals shows how to read one warm signal in detail.
How many of your leads can be hot at once?
Very few at any moment. The LinkedIn B2B Institute's 95-5 rule says its research shows 95% of your potential buyers aren't ready to buy today. On that page, research with the Ehrenberg-Bass Institute is cited showing that 80% of companies change banking services once every five years.
Two practical points follow. A list where half the leads are labelled hot is mislabelled, so check the reasons. And the 95% still matter: they are next year's hot leads, which is why the 95-5 page argues for reaching the whole category, not only the people in the market today. Our guide to sorting 1,000 leads by who to contact first turns this into a scoring sheet.
How do sales tools label hot, warm and cold leads?
Neither LinkedIn's intent scores nor HubSpot's default stages use hot, warm and cold as labels. This is how three systems label leads, checked on 24 October 2026:
| Tool | Labels | Based on |
|---|---|---|
| LinkedIn Sales Navigator, Buyer Intent | High, Moderate, Neutral, Negative (for accounts) | Activity such as following the company, company page visits, profile views, ad engagement, InMail responses and, with the Insight Tag, website visits |
| HubSpot | Lifecycle stages from Subscriber to Evangelist; lead statuses such as Attempted to Contact, Connected and Bad Timing | Forms, imports, workflows and manual updates; no hot, warm or cold by default |
| Siela AI SDR | Hot, warm or cold, each with a one-line reason | Fit, intent, recency and likelihood to reply |
LinkedIn's Buyer Intent FAQ says High means "a very active expression of buyer intent" and a good time to reach out, Moderate means the account is likely to respond, and Negative means an active expression of disinterest. Its activity list names the activities behind the score, and its Buyer Intent overview says the feature is for Advanced and Advanced Plus users. Read as temperatures, High is close to hot, Moderate to warm, and Negative means stop.
HubSpot's lifecycle stage guide (updated 20 October 2026) lists eight default stages and eight default lead statuses, and says you can customise them. If you want temperatures in HubSpot, add them as a custom property next to Lead status rather than renaming its stages.
How do you find warm leads?
Look where people have already paid attention to you or to the problem. A 30-minute weekly pass over these covers most warm leads a small team can find for free:
Your own post comments
Open your last five posts. List commenters who fit your buyer and wrote more than a few words.
New followers and subscribers
Check new followers on your profile and company page, and new newsletter sign-ups. Keep the ones who fit.
Timing changes at target accounts
New heads of the team you sell to, hiring posts for the work you do, funding news.
Old replies whose date has come
Anyone who said "try me in [month]" and that month is now. In HubSpot, the default Bad Timing lead status is a natural place to record these.
Write the signal and its date next to each name. A warm lead without a recorded reason is a cold lead you forgot about. Our list of 15 free buying signals has more places to watch.
What should you send to each type of lead?
Match the message to the evidence. These scripts are our own examples for this guide, with no measured reply rates behind them:
- Hot: answer the need. "Saw your post asking about tools for [task]. We built [product] for exactly that. Two questions so I don't waste your time: how many [units] a month, and what are you using now?"
- Warm: name the signal, ask one question. "Thanks for the comment on [post]. You mentioned [detail]. Is that something your team is working on now, or more of a someday problem?"
- Cold: give before you ask. "Hi [name], we put together [one-page checklist] for [role]s dealing with [problem]. Happy to send it. No call needed."
Answer hot leads first, the same day if you can. Our guide to speed to lead for small teams looks at what fast enough means when you can't staff a desk.
When does a lead change temperature?
A lead cools as its signal ages and heats up when it adds a stated need. Re-label weekly with rules like these:
- Hot to warm: no reply and no new signal after 14 days.
- Warm to cold: the newest signal is older than 60 days. LinkedIn's Buyer Intent lead filter uses a similar idea, surfacing leads at accounts with high or moderate intent in the past 30 days.
- Warm to hot: a warm lead asks a question about price, setup or a competitor.
- Any to stop: they say no or ask you to stop. Record it and don't contact them again for this offer.
- Cold to scheduled: "not now" with a date. Set a reminder for that date.
Siela's AI SDR scores every lead it finds hot, warm or cold with a one-line reason based on fit, intent, recency and likelihood to reply, and with Hot leads selected it only contacts leads scored hot. Normal, the default, starts with hot leads and then adds everyone who fits your customer profile, still skipping people who don't fit. Whatever you use, keep the reason with the label, so you can check whether the temperatures predicted who replied.
Frequently asked questions
Is a warm lead the same as a marketing qualified lead?
Not exactly. In HubSpot, a marketing qualified lead is a contact your marketing team has qualified as ready for sales, which is a judgement about readiness. Warm describes the evidence you have seen, such as a follow, a comment or a new role. Many warm leads never become marketing qualified leads, and teams set their own rules for both.
Is a referral a hot lead or a warm lead?
It depends on what the referrer said. If they passed on someone who asked for help with the problem you solve, that is a stated need and the lead is hot. If they only suggested you might get on well, the person knows your name but hasn't asked for anything, so treat them as warm.
How long does a lead stay hot?
There is no standard. We use 14 days with no reply or new signal before moving a hot lead to warm, and 60 days before warm becomes cold. LinkedIn's Buyer Intent lead filter looks at high or moderate intent in the past 30 days, which is a useful reference point for your own windows.
Can you buy a list of warm leads?
You can buy contact data, and some vendors sell intent data, but warmth comes from a signal tied to a date and a reason. A purchased list with no signal attached is a cold list, however it is labelled. Ask any vendor what signal put each person on the list and when it happened.
Should you contact cold leads at all?
Yes, carefully. LinkedIn's B2B Institute says 95% of potential buyers aren't ready to buy today, so most of your market is cold at any moment. Contact them with something useful and no pitch, or reach them through content, so they remember you when they do start looking.
