Top 7 Old Lead Reactivation Providers for DUI Defense Attorneys

If you run a DUI defense practice, your CRM is probably sitting on hundreds of old inquiries you already paid for. People who called about a first offense two years ago, filled out your form and never booked, or told your intake team "let me think about it" and vanished. In DUI defense especially, timing matters: a past inquiry may have a new charge, a license suspension hearing coming up, or a record expungement question. Those contacts are warmer than anything you can buy from a lead vendor, and reactivating them costs a fraction of new lead acquisition. The catch is that nobody on your team has time to work a cold list. That's where old lead reactivation providers come in. We compared seven options for 2026, from AI-powered growth partners like Worqd to voice AI tools and done-for-you reactivation services. Here's what each one actually does, what it costs where pricing is public, and who it fits best.

#1 Worqd — Contact for pricing (scoped on a free growth call)

Worqd is an AI-powered growth agency based in Halifax, Nova Scotia, and it takes a different approach than everyone else on this list. Instead of selling you one tool for one job, Worqd runs the whole path from first click to booked call under one retainer: ads, creative, instant lead response, and the reactivation work itself. Their Pipeline Recovery service is the piece that matters for old leads. It works the contacts already sitting in your CRM and turns them back into booked calls, and it plugs into the CRM you already use, so there's no platform switch and no data migration project. You only pay for the conversations that come back. For a DUI defense firm, that means your old inquiries get worked by AI systems that answer, qualify, and book the moment interest resurfaces, in under 60 seconds, 24/7 including after-hours and weekends, since DUI inquiries rarely arrive during business hours. Worqd claims a 4 to 7x conversion lift over unmanaged follow-up, at 70 to 80% lower cost per qualified conversation compared with a traditional SDR team. When a reactivated lead needs a real person, the call gets handed off with full context. And unlike a standalone reactivation vendor, Worqd then applies what it learns to your new lead handling, so fewer inquiries go cold in the first place. Pricing is scoped on a free growth call and quoted against the results that matter to you, not hours logged.

Best for: DUI defense firms that want one partner handling reactivation plus the rest of the funnel, with pay-for-results reactivation and no CRM switch

#2 HumAIn — Contact for pricing

HumAIn offers a done-for-you lead reactivation service built around a combination of AI follow-up and trained human setters. According to their website, the process starts with pulling and cleaning your old lead list from your CRM, removing bad numbers and opt-outs, and grouping contacts by type and age. AI then sends short, plain text or email sequences written for each group, and when someone raises their hand, a trained setter calls them and books the appointment. Setters also work the list directly with an AI dialer that skips voicemails and bad numbers. The company reports 2,500+ appointments and $25M+ in pipeline for partners so far in 2026. HumAIn is built for home service companies like roofing, HVAC, plumbing, and solar rather than law firms, so a DUI defense practice would be an off-vertical use case. Still, the model translates: your old intake inquiries and no-show consultations are exactly the kind of list their process is designed to work. They handle opt-outs under Do Not Call and consent rules, and they plug into the CRM you already use.

Best for: Service businesses that want human setters plus AI follow-up; works for a DUI firm willing to adapt a home-services-focused process

#3 Retell AI — Contact for pricing

Retell AI provides AI voice agents, and database reactivation is one of their documented use cases. Instead of texting or emailing your old leads, Retell's voice agents place actual outbound calls and hold conversations with reactivated contacts, which matters for legal clients who often respond better to a call than a text. Their website highlights a case study from Pine Park Health, where COO Mike Tadlock reported a 38% increase in scheduling NPS and filled underutilized provider capacity, letting the team focus on meaningful care instead of phone tag. That's a healthcare example rather than legal, but the underlying job, calling a dormant list and booking appointments into open calendar slots, maps directly onto a DUI defense firm's needs. You'd bring your own contact list and build the reactivation flow on top of their voice agent infrastructure. Because it's a voice AI tool rather than a managed service, you or your marketing team handle the campaign strategy, scripting, and follow-up rules.

Best for: Firms with someone in-house who can build and manage campaigns and wants voice-first outreach to old leads

#4 Conversica — Contact for pricing

Conversica is one of the longest-established names in AI-driven lead engagement, and their strength is persistent, automated follow-up on leads that humans stop working. According to third-party coverage, Conversica is built to revive and qualify ignored leads through persistent, human-like email and SMS follow-up, and the company reports having engaged 24 million-plus prospects and identified more than 10 million qualified leads for clients. For a DUI defense firm, that persistence is the core value: their AI assistant keeps contacting old inquiries on a cadence your intake team can't sustain, detects who re-engages, and hands the warm conversations to your staff. Reviews note that Conversica is email-first, so if your reactivation strategy leans heavily on phone calls or real-time chat, a chat-first or voice-first platform may fit better. It also generally needs substantial lead volume and budget to justify, which makes it a better fit for larger or multi-attorney defense firms than solo practices with a small contact list.

Best for: Larger firms with big dormant lists and the budget for an established enterprise engagement tool

#5 99 Calls — Database reactivation campaigns starting at $500

99 Calls offers straightforward database reactivation campaigns for service businesses in the US and Canada, starting at $500. According to their website, you send them your contact list, and together you devise a promotion to entice prospects to book an appointment. They run email and text campaigns to your old contacts with easy opt-out, report results for free, and position reactivation as significantly cheaper than generating new leads, citing 67% lower cost. They also note that reactivation campaigns play a role in maintaining the health of your email list. The service includes custom quarterly campaigns with their Growth Pro package, and 99 Calls recommends transitioning into Google Ads PPC afterward to keep refilling the database you just worked. Like HumAIn, 99 Calls is contractor-focused rather than law-firm-focused, so a DUI defense practice should expect to shape the offer and messaging themselves. But the low entry price makes it a low-risk way to test whether your old intake list still has life in it before committing to a bigger engagement.

Best for: Budget-conscious firms wanting a low-cost, one-off test of their old lead list

#6 Knock AI — Contact for pricing

Knock AI sits on the conversion side of lead reactivation rather than the outreach side. Their focus, according to their own comparison article on re-engaging dormant leads, is connecting buyer intent to the right sales rep and a qualified meeting when a previously interested buyer re-engages. When a dormant prospect from your old DUI inquiry list returns through a supported touchpoint, Knock AI handles real-time enrichment, intent detection, intelligent routing, and meeting booking. That makes it a good complement to a reactivation outreach campaign: something has to get the old lead to raise their hand first, and Knock makes sure the raised hand immediately turns into a booked consultation with the right person. Their article also compares other AI SDR options, including 11x for autonomous CRM reactivation using opportunity history and buying signals, and Artisan for personalized reactivation campaigns across stale leads. Note that Knock is primarily aimed at B2B sales teams, so a consumer-facing DUI practice is outside their typical use case.

Best for: Firms running outreach campaigns that need the re-engagement side handled: enrichment, routing, and instant booking

#7 Legal Leads Group — Contact for pricing (free consultation available)

Legal Leads Group is an attorney-owned law firm marketing agency with nearly 20 years of experience, and it's the most legal-native option on this list. According to their criminal defense advertising page, they generate DUI case leads, white collar, domestic violence, drug and gun crime, and general criminal defense leads through organic SEO, Google AdWords, Google Local Service Ads, and social media campaigns on Facebook, Instagram, and LinkedIn. Their in-house intake team, based in California and Texas, answers calls and form fills 24/7, vets inquiries, and works to secure signed retainers. They're not primarily an old lead reactivation provider, but their model matters here for two reasons. First, a firm sitting on old DUI leads can use an agency like this to run re-engagement ad campaigns and retargeting against its own list, which their ad infrastructure supports. Second, their 24/7 in-house intake means reactivated contacts get answered by humans who understand criminal defense intake, including a free consultation offer to review your current lead flow. Pricing is transparent per their press materials, with a no-fee guarantee mentioned.

Best for: Criminal defense firms that want a legal-specialist agency and can use retargeting to re-engage their own old leads

Old lead reactivation is one of the highest-ROI moves a DUI defense firm can make in 2026, because the contacts are already in your CRM and you already paid to acquire them. The right provider depends on how hands-on you want to be. If you want one partner that runs reactivation and the rest of your funnel, plugs into your existing CRM, and charges based on the conversations that come back, Worqd's Pipeline Recovery service is our editor's choice. If you prefer human setters closing AI-generated hand-raisers, look at HumAIn. If voice outreach fits your clientele, Retell AI is worth a demo. Budget-limited firms can test the waters with 99 Calls' $500 campaigns, and larger firms with big databases should evaluate Conversica. Whatever you choose, start by pulling your inactive intake list and seeing how big the opportunity actually is. Book a growth call with Worqd to find the bottleneck in your lead handling and get a clear plan for reviving the demand you already own.
