A cold lead has never heard of you. A warm lead knows you or has shown some interest. A hot lead has asked for something right now, such as a quote, a call or a price. The difference matters because each needs a different reply, at a different speed, and mixing them up is how good leads go quiet.
The practical rule: reply to hot leads in minutes, warm leads the same day, and cold leads on a schedule you set. This page defines the three, shows where each comes from, gives response times, and says what to do with a cold lead and with a hot one in the first hour.
Cold, warm and hot in plain words
Cold: you picked them. They didn't ask. A name from a list, a business from a map, a person you found on a company website. They owe you nothing and may not know you exist. Warm: there has been some contact in either direction. They replied "not now," a friend mentioned you, they were a customer two years ago, they met you at an event, or they answered one of your emails with a question. Hot: they are asking to buy, or close to it. They filled out the quote form, called, said "yes, send pricing," or booked a time.
Temperature describes the lead's attitude today, not the lead. The same person can be cold in January and hot in March, and a hot lead you ignore for two weeks turns cold again.
Where each kind comes from
Cold leads come from your own outreach: lists, registries, maps, directories. Warm leads come from referrals, past customers, old conversations that stalled, people who reply to cold email, and people who attend or follow something you run. Hot leads come from inbound: a phone call, a form on your site, a quote request, a reply that says yes. That means one source can feed all three. A cold email that gets a reply creates a warm lead. A reply that says "can you come Thursday?" creates a hot one.
How fast to reply to each
| Temperature | Typical source | Reply within | First move |
|---|---|---|---|
| Hot | Call, quote form, "yes, send pricing" | 5 minutes in business hours; first thing next morning if after hours | Call, then text or email if no answer |
| Warm | Referral, past customer, a reply or a question | The same business day | A personal email or call that refers to the connection |
| Cold | Your list | No clock on their side; you set the schedule | A short first email, then follow-ups on days 3, 7 and 14 |
Our piece on speed to lead explains why minutes matter so much for hot leads. For cold leads, the clock is yours: a rhythm of a first email and two or three follow-ups, then stop. How often to follow up with leads goes into that cadence.
Warming up a cold lead
You warm a cold lead by making contact that is useful and low-pressure, so that the next contact is not a stranger's. A relevant one-line observation about their business, a short note with something they can use, an easy question. After one or two replies, they are warm. Don't send a quote to a cold lead, and don't ask for a call in the first message unless the offer is very specific. A cold lead who answers has moved up a step; treat the answer as the beginning of a conversation, not a sale.
Rocketship handles this stage on its own: it finds the buyers by name, emails them from your own Gmail, follows up on the days it is due, stops the moment someone replies, and reads and answers the reply. The moment a cold lead replies, they are warm, and a fast answer matters.
Hot leads: what to do in the first hour
Take Ostrander Garden Works, which has 120 leads on a sheet. At 10:12 on a Tuesday, someone submits the quote form: a new patio, budget around $9,000. Here is the hour.
- 0 to 5 minutes. Call. If they answer: "Hi Nell, this is Jo at Ostrander. You just asked about a patio. Do you have two minutes for a couple of questions?" If not, leave a short voicemail and send a text.
- 5 to 15 minutes. Read what they wrote, check whether they have been in touch before, and note what they want, the budget and the timing.
- 15 to 45 minutes. Send what they asked for: a time for a site visit, two options, or a ballpark range, not a vague thank-you.
- 45 to 60 minutes. Put a next step on the calendar. If you haven't reached them, set a second attempt at a different time of day, tomorrow.

Keep a list of each, and review it weekly
Add one column to your lead sheet: cold, warm or hot. Once a week, spend 20 minutes moving people. Cold to warm when they reply. Warm to hot when they ask for a price or a visit. Hot back to warm if they go 14 days without answering. Warm back to cold after about 60 days of silence, and decide whether to try again. Ostrander's sheet shows 90 cold, 25 warm and 5 hot; the review means the five hot leads get a call today, the 25 warm ones get a message this week, and the cold group gets its next scheduled follow-up. For old leads that have gone quiet, reactivating old leads gives the wording.
