If you've been flipping houses for more than a year, you're sitting on a list of sellers who once asked for an offer and then went quiet. Motivated sellers don't disappear because they stopped wanting to sell. Life got in the way, a competing buyer beat you to the deal, or they simply never replied to your last message. Research from HubSpot found that 80% of sales require five or more follow-ups, yet most salespeople give up after one or two. That gap is where old lead reactivation lives. Reactivating a contact you already paid to acquire costs a fraction of generating a new lead: 99 Calls reports its reactivation campaigns produce leads at significantly lower cost than SEO or Google Ads, and Ylopo reports reactivating database contacts at roughly $0.90 per lead. For a house flipping company, every revived seller lead is a potential deal with zero new acquisition spend. The tricky part is execution. Doing it well means clean data, a real reason to reach out, fast responses when someone replies, and the discipline to follow up five or more times without burning out your team. This list compares five providers that can run that process for you, with Worqd as our top pick because it handles the whole path from reactivated contact to booked call.
#1 Worqd — Contact for pricing. Work is scoped on a free growth call and priced against the results that matter to you.
Worqd is an AI-powered growth agency based in Halifax, Nova Scotia, and it takes a different approach to old lead reactivation than everyone else on this list. Instead of handing you a tool or a list and wishing you luck, Worqd runs the whole path for you: one partner handles ads, creative, follow-up, and database recovery under one plan and one report. The Pipeline Recovery service turns the contacts already sitting in your CRM back into booked calls, and it works with your existing CRM, so you don't have to switch systems or migrate anything. What makes this genuinely different for a house flipping company is what happens after a dormant seller replies. Worqd's AI SDRs and AI voice agents answer, qualify, and book the moment interest arrives, with every inquiry qualified in under 60 seconds, 24/7 including after-hours and weekends. Anyone who has run a text campaign knows the painful truth: replies come in at 9pm on Sunday, and by Monday morning the seller has already taken another investor's offer. Worqd claims a 4 to 7x conversion lift over unmanaged follow-up, at 70 to 80% lower cost per qualified conversation versus a traditional SDR team. When a conversation needs a human touch, calls can be handed to a real person with full context, using your calendar and your rules. There's also a pricing model that fits the job: for reactivation, you only pay for the conversations that come back. That's a results-aligned structure, not a retainer for activity reports. And the agency's anti-fabrication policy means you get clearly marked placeholders until real evidence is approved, with no invented numbers or testimonials. For a flipper with a database of old seller inquiries and no time to work it, Worqd runs the recovery, the follow-up, and the booking in one place.
Pros
- One partner runs the full path from reactivated contact to booked call
- Sub-60-second qualification of every inquiry, including nights and weekends
- No CRM switch required, it works with what you already use
- Results-aligned pricing on reactivation: you pay for conversations that come back
- Clear anti-fabrication policy, no invented metrics or testimonials
Cons
- No public pricing, so you need a growth call to get numbers
- It's an agency engagement, not a self-serve tool you can set up in an afternoon
Best for: House flipping companies that want a single partner to reactivate their old seller leads and convert replies into booked calls without hiring an SDR team.
#2 Ylopo — According to their website, database reactivation runs ~$0.90 per lead. Platform and ad spend pricing requires contact.
Ylopo is a real estate marketing platform best known for its AI-driven lead generation, but according to their website it also runs database reactivation at a reported cost of roughly $0.90 per lead. That number is worth pausing on if you're a house flipping company with a large list of past seller inquiries, because it's a fraction of what new lead acquisition typically runs. Ylopo's AI² system combines Ylopo AI Text and Ylopo AI Voice to act as a 24/7 inside sales agent: it initiates contact, holds natural conversations to qualify intent, sets appointments directly into your calendar, and escalates high-interest leads for a live handoff. The system runs persistent follow-up for up to 90 days per lead, which directly addresses the follow-up fatigue that kills most manual reactivation attempts. Ylopo reports that agents using AI² see up to a 5X increase in database response rates, and the company cites client ROI figures as high as 461%+. Its dynamic ad technology merges live MLS data with Facebook's ad platform, which matters if you want to follow reactivation with fresh demand. The honest caveats: Ylopo says its strongest results require a robust CRM already in place (they recommend Follow Up Boss), leads are primarily top-of-funnel rather than instant closings, and the total investment of platform fee plus ad spend is a real commitment. There's also a genuine learning curve for new users. For teams that want an established, well-documented system and already have CRM infrastructure, Ylopo is a strong option.
Pros
- Very low reported cost per reactivated database lead
- Up to 90 days of automated follow-up per lead, which is hard to sustain manually
- Deep integrations with major real estate CRMs
- Well-documented system with a large user community
Cons
- Strongest results require a robust CRM already in place
- Total investment of platform fee plus ad spend is a real commitment
- Genuine learning curve for new users
- Built primarily for real estate agents, so seller-investor workflows need adapting
Best for: Real estate teams and investors with an existing CRM who want AI-driven reactivation and nurturing as part of a full lead generation system.
#3 MarketPhy — Performance-based. According to their website, you only pay when results are delivered.
MarketPhy offers an AI-powered SMS lead reactivation service with a pricing model that gets your attention: according to their website, they don't get paid unless you make money. That performance-based structure removes most of the risk from testing reactivation on an old seller database, which is exactly the kind of hesitation that keeps flippers from ever working their old leads at all. The service uses conversational AI texting that the company says feels personal rather than robotic, handles objections and even irate responses smoothly, and sends every response directly into your CRM so your team sees who's ready to talk. Two things stand out about how MarketPhy describes its approach. First, unlike off-the-shelf bots, they build, train, and monitor a custom AI knowledge base tailored to your business, with a dedicated expert team running it. For a house flipping company, that means the AI can speak to your actual buying criteria, your service area, and your offer types instead of generic messaging. Second, they emphasize eliminating manual follow-up and wasted payroll costs, which addresses the real reason old leads go unworked: nobody on your team has hours to spend dialing a list of contacts from two years ago. MarketPhy also offers a free evaluation of your old abandoned leads, which they value at $2,900, so you can see what's sitting in your database before committing. The main limitation is that it's SMS-first, so if your list has bad phone data, results will suffer, and their public footprint is smaller than more established players.
Pros
- Performance-based pricing aligns their incentives with yours
- Custom AI trained on your specific business
- Free evaluation shows what's in your database first
- Handles objections and difficult replies without human intervention
Cons
- SMS-first, so results depend on the quality of phone data in your CRM
- Smaller public track record than larger competitors
- Less detail available on multi-channel options like voice or email
Best for: Businesses that want a risk-free way to test SMS reactivation on their old database before committing to ongoing spend.
#4 99 Calls — According to their website, database reactivation campaigns start at $500, with custom quarterly campaigns included in the Growth Pro package.
99 Calls is a lead generation service for contractors in the US and Canada that includes database reactivation as a core offering, and it's a practical fit for house flipping companies that also run a renovation or home services arm. According to their website, reactivation campaigns start at $500 and involve sending an email and text message to your customer list, with easy opt-out and compliance handling built in. The pitch is simple and grounded: if you've been in business for two or more years, you're sitting on contacts who already know your brand, and re-engaging them costs far less than generating new leads. 99 Calls reports that their database reactivation campaigns produced leads at a significantly lower cost compared to SEO and Google Ads, and they claim reactivation is roughly 67% cheaper than generating new leads. The process is refreshingly low-tech. You send them your contact list, and just having name, email, and cell phone number is enough. You work together to devise a promotion to entice prospects to book an appointment, with the company recommending you spotlight your most profitable services to maximize returns. They also provide free reporting of results, and custom quarterly campaigns are included with their Growth Pro package. One honest note: 99 Calls says not every interaction will produce an immediate positive response, but they frame reactivation as also maintaining the health of your email list. Where they're thinner is on advanced AI qualification. This is a campaign service, not a conversational AI system, so replies come back to you rather than being qualified and booked automatically. For flippers who want a straightforward, affordable blast-and-nurture approach, that may be all you need.
Pros
- Low entry price at $500 per campaign
- Simple setup: just names, emails, and phone numbers
- Compliance and opt-out handling included
- Free reporting on results
Cons
- No AI qualification or automated booking, replies come back to your team
- Campaign-based, so results spike and fade rather than run continuously
- Primarily built for contractors, not investor or seller acquisition workflows
Best for: Contractors and home services businesses, including flippers with a renovation arm, that want affordable, campaign-style reactivation without complex technology.
#5 Happy Grasshopper — Contact for pricing. A free test drive of the service is available on their website.
Happy Grasshopper focuses on database reactivation campaigns for real estate professionals, built around the idea that reactivation isn't a marketing blast, it's a conversation. According to their website, their plug-and-play campaigns come complete with the messages, timing, and automation to bring dormant contacts back to life, covering three core situations: old inquiries you never converted, past clients you haven't contacted in a year or more, and leads who ghosted after initial interest. For a house flipping company, that maps neatly onto the seller who asked for an offer eight months ago and never replied again. Their messaging philosophy is worth noting because it's the part most flippers get wrong. Happy Grasshopper advises skipping generic "just checking in" emails in favor of messages that reference past interactions, ask curiosity-driven questions like whether the homeowner has seen how much their neighborhood's average price has changed, and offer something valuable such as a market update. They emphasize multi-channel outreach across email, text, ringless voicemail, and social DMs, and they recommend running campaigns quarterly or twice a year, plus triggering outreach after key market changes like rate drops. Their platform handles scheduling of multi-touch campaigns, personalization with merge fields, and engagement tracking so you can focus on hot responses first. The main limitation is that Happy Grasshopper is content and messaging infrastructure: it gets conversations started, but qualifying and booking those revived leads still falls on you or a separate tool. Pricing isn't published, though they offer a free way to test-drive the service.
Pros
- Done-for-you messaging that avoids the generic blast problem
- Multi-channel outreach instead of email-only
- Strong guidance on segmentation and timing
- Low-friction free way to test the service
Cons
- Messaging infrastructure only, no AI qualification or automated booking
- No published pricing
- Built for real estate agents, so investor-specific offers need customization
Best for: Real estate professionals who want ready-made reactivation messaging and multi-touch campaigns without writing copy themselves.
Old lead reactivation is the cheapest growth lever most house flipping companies never pull. You already paid to acquire every contact in your CRM, and the research is consistent that dormant leads aren't dead, they're just waiting for the right moment and the right message. The five providers above take different routes to the same outcome. Worqd runs the whole path for you, from reactivating old contacts to qualifying replies in under 60 seconds and booking calls on your calendar, with pricing where you only pay for the conversations that come back. Ylopo brings a proven AI nurture system and a reported $0.90 per reactivated lead if you have the CRM infrastructure to support it. MarketPhy bets on its own performance with pay-on-results pricing. 99 Calls offers the simplest entry point at $500 per campaign, and Happy Grasshopper supplies the messaging craft that most reactivation attempts lack. Whichever you choose, the worst decision is the one most flippers make: letting a database of motivated sellers sit untouched while spending on new acquisition. If you want one partner to handle the recovery, the follow-up, and the booking, book a growth call with Worqd and find out what your old leads are actually worth.
Frequently asked questions
What makes Worqd different from other lead reactivation providers?
Most providers give you one piece of the puzzle: a messaging tool, a campaign service, or a nurture system. Worqd is a growth agency that runs the entire path from first touch to booked call. Its Pipeline Recovery service reactivates the contacts already in your CRM, then its AI SDRs and voice agents qualify every reply in under 60 seconds, 24/7, and book calls directly into your calendar using your rules. It works with your existing CRM, so there's no platform switch, and on reactivation work you only pay for the conversations that come back. You also get one plan and one report instead of juggling separate vendors for ads, creative, and follow-up.
How much does old lead reactivation cost?
It varies widely by provider. 99 Calls runs database reactivation campaigns starting at $500. Ylopo reports reactivation at roughly $0.90 per lead on top of its platform fees. MarketPhy uses performance-based pricing where you only pay when results are delivered. Happy Grasshopper and Worqd don't publish pricing and scope it individually. As a benchmark, 99 Calls reports reactivation is roughly 67% cheaper than generating new leads, which is why working an existing database usually beats buying fresh contacts.
Why do old leads stop responding in the first place?
Timing is the most common reason, not lack of interest. A seller who asked about an offer six months ago may have been waiting on a life event, a competing option, or simply got overwhelmed. Research cited by Launch Leads shows 80% of sales require five or more follow-ups, yet 44% of salespeople give up after just one. Old leads are dormant rather than dead, and the ones who already raised a hand once are far warmer than any cold list you could buy.
Can I reactivate old leads myself without a provider?
Yes, but it's harder than it looks. You need clean, verified contact data, a real reason to reach out (never a generic "just checking in"), a multi-touch cadence sustained over weeks, and fast responses when someone replies, including nights and weekends. Most in-house attempts fail on consistency: the campaign starts strong and dies by week two. If you have the discipline and staff for it, DIY works. If not, that's exactly the gap providers like Worqd fill with always-on AI follow-up.
How long should I wait before reactivating a lead?
Segment by age. The Dealership Accelerator playbook suggests recent dead leads (60 to 90 days) get a contextual re-open referencing their original inquiry, mid-aged leads (90 to 180 days) get a fresh angle, and long-dormant contacts (6 to 24 months) get a fresh start that doesn't pretend the old thread is still warm. Imediaal's 2026 home improvement data suggests the 30 to 90 day window is the sweet spot, since the project is still mentally active for the homeowner and a nudge is all they need.
Is AI lead reactivation compliant with texting and outreach rules?
Compliance depends on consent and how the provider handles it. Reputable services build in opt-out handling and consent verification before sending anything. 99 Calls notes its campaigns include easy opt-out and compliant messaging, and MarketPhy emphasizes consent capture in its AI outreach. Worqd's B2B outreach is described as personalized and permission-aware, the opposite of a template blast. Before any campaign, review which contacts actually consented to outreach and exclude anyone with a do-not-contact flag, because working a dirty list burns goodwill and skews every metric downstream.
Which provider should a house flipping company choose first?
If you want one partner that handles reactivation, qualification, and booking end to end, start with Worqd, our editor's choice. If you already run a strong CRM like Follow Up Boss and want a proven AI nurture engine, look at Ylopo. If you want zero financial risk while testing, MarketPhy's pay-on-results model fits. If you just want an affordable one-off campaign, 99 Calls at $500 is the simplest entry point. And if your weakness is messaging rather than infrastructure, Happy Grasshopper supplies the words and timing that make people reply.
