How to Follow Up With Leads: A Seven-Part Lead Follow-Up System

To follow up with leads without dropping any, build a system with seven parts: every source flowing into one place, a first response within minutes, a cadence for people who don't reply, a few qualifying questions, a rule for when a person takes over, conditions that stop follow-up, and long-term nurture for people who aren't ready yet.

Each part can be run by hand, by a drip sequence, or by AI lead follow-up: software that texts each new lead, reads the replies, and decides what to say next and when to check in again from that conversation rather than a fixed schedule.

In Harvard Business Review's 2011 research, firms that tried to reach an online lead within an hour were nearly seven times as likely to qualify it as firms that waited even an hour longer, and in a separate audit of 2,241 US companies, 23% never responded at all (Harvard Business Review, 2011). Speed to lead covers the first hour in detail.

AI follow-up vs. a drip sequence

A drip sequence is a list of messages with delays you write ahead of time ("day 1: text A, day 3: text B"); AI follow-up has no list and decides each message after reading the last reply.

	Drip sequence	AI lead follow-up
Who decides timing	You, in advance, the same for every lead	The AI, per lead, from what was said ("call me after the 15th")
Who decides content	You write every step; merge fields fill in the name	The AI writes each message from the conversation and the lead's details
What happens on a reply	The sequence pauses or ends, and a person has to answer	The AI answers, asks the next question, and picks the next check-in
How it stops	Last step sent, or a rule fires (reply, tag, opt-out)	Opt-out, a "no", a handoff to a person, or the goal is met
What you build	Steps, delays, branches, exit rules	Your goal, who gets ready leads, and the facts it may use
Typical failure	A lead replies and no one sees it for a day	It says something you wouldn't, so you read the conversations

Drips still fit one-way news (a newsletter, a rate update) where no reply is expected. If your CRM already runs drips, Out Nurture vs. workflow marketing automation compares the two setups.

A follow-up system that doesn't drop leads

1. Lead intake

Send every source to one place automatically: web forms, Facebook and Google lead ads, portals, your CRM. Most tools take a webhook, a native connector or a CSV upload. A lead that lands in an email inbox gets no first text until someone copies it into the system. Pass along the details the lead gave (source, what they asked about, notes) so the first text can mention them.

2. First response

Text within minutes, mention what the lead did, and ask one easy question. Leave out links in the first message.

Example: "Hi Dana, this is Sam with Acme Roofing. You asked for a quote on a roof repair in Northpark. Is it leaking now, or are you planning ahead?"

3. Cadence for non-responders

If you run follow-up by hand or with rules, start with this schedule for texts and adjust it. Change the wording every time and stop the moment the lead replies.

When	Message
Within 5 minutes	First text, as above
Same day, 3 to 4 hours later	A shorter nudge with a yes/no question
Day 2	Something useful: an answer to what they asked, a price range, an opening this week
Day 4 or 5	A different angle or a different time of day
Day 10	"Should I close this out, or is it still on your list?"
Then monthly	Long-term nurture (step 7)

Federal rules bar telephone solicitations before 8 AM or after 9 PM in the recipient's time zone (47 CFR 64.1200(c)(1)). Some states are stricter: Florida limits commercial telephone solicitations to 8 AM to 8 PM and to three per person per 24 hours on the same subject (Florida Statutes section 501.616(6)).

Every local 10-digit number you text from also needs an approved A2P 10DLC registration, or carriers block the messages. The brand and the messaging registration each go through carrier review, so file before you connect lead sources; the A2P 10DLC guide lists the fees and review times.

4. Qualifying questions

Ask one question per text, in the order below. Skip any the lead already answered on the form.

5. Handoff rule

Write down exactly what "ready" means, and who gets the lead when it happens. Examples: "asked to see a home, has a timeline under 90 days" or "wants an inspection this week". Hand off in a way the salesperson can't miss (a group text with the lead, or a message with the conversation so far), and set a time limit for the person to respond, such as 15 minutes during business hours.

6. Stop conditions

• Opt-out: under FCC rules, "stop", "quit", "end", "revoke", "opt out", "cancel" and "unsubscribe" each revoke consent, and so does any other reply a reasonable person would read as a request to stop. You must honor it within 10 business days and may send one confirmation text with no marketing in it (47 CFR 64.1200(a)(10) and (a)(12)).
• A clear no ("already bought", "went with someone else", "not interested"): send one polite closing text and stop.
• Wrong number: remove the number from every list, not just this campaign.
• Handed off: once a person owns the lead, automation stops so the lead doesn't get two voices.

7. Long-term nurture

When a lead says "not yet", ask what they're waiting for. An answer like "after my lease ends in March" gives you a date. Check in near that date, mention it, and ask one question. Between dates, a monthly or quarterly text is enough. A lead who said "next spring" has told you when to text again; put that date on the lead.

How qualification works over text

Text qualification is a short interview, one question at a time, ordered from the easiest question to the most personal:

1. Need: what they want and why now. "Is this for a repair or a full replacement?"
2. Timeline: "When are you hoping to have this done?"
3. Money: budget, financing or insurance. "Will this go through insurance, or out of pocket?"
4. Decision: who else decides, and whether they're talking to anyone else. "Is anyone else involved in picking the contractor?"
5. Next step: the thing your team wants. "I can have someone out Thursday at 10 or 2. Which works?"

Industry (adjusted questions)	Timeline	Money	Decision
Real estate	When they want to move	Talked to a lender? Need to sell first?	Already working with an agent?
Mortgage	Under contract, or shopping?	Rough price, down payment	Co-borrower?
Insurance	When the current policy renews	Current premium	Who's on the policy?
Home services	Urgent or planned	Insurance claim or cash	Owner or renter?

The real estate ISA guide has the full real estate list. Here is an illustrative exchange (not a real customer) after the roofing text above:

Lead: Just planning ahead. It's an old roof.

Agent: Makes sense. Are you thinking this year, or more like next spring?

Lead: Probably spring, after we get our tax refund.

Agent: Got it. I'll check back in early March. Want a rough price range now so you can plan?

That reply sets the next follow-up date (early March), answers the money question (tax refund), and keeps the lead out of a sales rep's queue until it's useful.

Guardrails for the AI

• Give it the facts it may use: service area, price ranges you're willing to quote, hours, what happens at an appointment. Tell it what it may not do, such as quote a final price, promise availability or give legal, tax or coverage advice.
• Pilot on one lead source for a week or two before turning it on for everything, and compare it against the same source's previous month.
• Read conversations daily for the first two weeks, and weekly after that. Look for promises, wrong facts and questions it couldn't answer.
• Decide what happens on an unknown question: the AI should say someone will get back to them and flag the thread for a person, not guess.
• Make it easy for a person to jump in on any thread, and make sure the AI stops once someone does.

Consent before the first text

Collect texting consent on the form or ad itself: a separate, unchecked checkbox that names text messages, says message frequency varies and that message and data rates may apply, and explains HELP and STOP. Keep the form version, the timestamp and the source with each lead so you can show where consent came from; the A2P guide has opt-in wording that passes carrier review. The stakes are real: the TCPA lets a consumer sue for $500 in damages per violation, and a court can triple that if the violation was willful or knowing (47 U.S.C. 227(b)(3)).

What it costs per lead

If a tool charges per message, the cost per lead is messages per lead times the price per text. At 10 texts per lead (an assumption; long nurture sends more) and Out Nurture's usage rate of about $0.025 a text, that's about $0.25 a lead, plus the $25 monthly plan. Compare it with your current cost per lead worked: a person's loaded hourly cost times the minutes they spend per lead, or a drip tool's monthly fee plus the time someone spends answering replies.

What to measure

• Time to first text, as a median, and the share of leads that got one at all.
• Reply rate by lead source. Published averages mix industries and channels, so take your own baseline from the month before a change and compare against it. If one source's rate is much lower, check its consent and data first: wrong numbers and leads who never asked to be texted look like bad follow-up.
• Qualified or handed off, as a share of leads who replied.
• Handoff response time: how long a person takes to pick up a ready lead.
• Handoff to appointment held. If this is low, the "ready" definition is too loose.
• Opt-out rate per message. A jump after a change in wording or timing means back it out.
• Leads with no next step: not opted out, not closed, nothing scheduled. This number should be zero.

Choosing a tool

• Timing: does it decide when to follow up from the conversation, or do you build the steps and delays?
• Control: can you read every thread and take over, and does the AI stop when you do?
• Opt-outs: is a STOP honored across every campaign and number, including plain-language requests?
• Hours: are quiet hours set by the lead's time zone or yours?
• Registration: who files the A2P 10DLC registration, and who pays the carrier fees?
• Handoff and CRM: how does a ready lead reach a person, and do handoffs and opt-outs get written back to your CRM?
• Pricing: per text, per seat or per contact, and what a long nurture costs at your volume.

When not to automate

• Numbers without consent, such as bought lists, scraped numbers or an old CSV export where you can't show where consent came from: don't text them at all.
• A lead who asked for a phone call: call them.
• Advice with legal or financial weight: rate quotes, coverage decisions, anything you would need a license to say. Let the AI collect details and hand off.
• Complicated or sensitive situations: divorce, a death in the family, a claim dispute.
• Very few leads: at a handful a week, one person with reminders can answer each one directly.

If you use Out Nurture

Out Nurture is an AI sales agent that does this over two-way SMS. Leads come in by webhook, API or CSV, and it uses every detail sent with them. It texts a new lead within seconds during texting hours, decides each reply and when to follow up next, and only sends proactive texts between 8 AM and 9 PM in the lead's time zone. There are no sequences to build: you set what a win is and who gets ready leads, and it hands off by group text or an email summary. STOP and "remove me" are honored immediately across every campaign. The cost calculator works out the monthly cost for your lead volume.
