If you run an event marketing agency, you already know the pattern. Every conference, trade show, or webinar your clients exhibit at generates a burst of badge scans, form fills, and booth conversations. Then the event ends, the team moves to the next deadline, and those contacts quietly cool off in the CRM. Research across the industry suggests most leads never get a proper follow-up sequence, which means the money your clients spent on that booth is still sitting in their database, unclaimed. Old lead reactivation, sometimes called database reactivation, is the practice of going back to those dormant contacts with a structured, multi-touch campaign and turning them into booked conversations. It's cheaper than fresh acquisition because the leads are already paid for. Below are four providers that can help an event marketing agency recover that missed demand, starting with the one we'd pick first.
#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 shape than everyone else on this list. Instead of selling you a tool you have to configure, Worqd operates as a retainer-style growth partner, and one partner runs the whole path from first click to booked call. For event marketing agencies, that matters. Reactivating old event leads works best when the follow-up is fast, personal, and actually books something, and Worqd's Pipeline Recovery service is built exactly for that: it turns the contacts already sitting in your client's CRM back into booked calls, working with the existing CRM so nobody has to switch tools. You only pay for the conversations that come back, which aligns the agency's incentives with yours. The reactivation work is handled by AI SDRs and AI voice agents that answer, qualify, and book the moment interest arrives, in under 60 seconds, 24/7 including after-hours and weekends. If a conversation gets warm, it can be handed to a real person with full context, using your calendar and your rules. Worqd claims a 4-7x conversion lift over unmanaged follow-up, at 70-80% lower cost per qualified conversation than a traditional SDR team. The other reason we rank it first: reactivation is one pillar of a full growth engine. The same partner can handle paid ads, creative testing, and AI search visibility, so your agency gets one plan and one report instead of juggling separate vendors. Worqd also offers white-label creative for agencies, and it's upfront about evidence: until real results are approved, it uses clearly marked placeholders rather than inventing testimonials or client logos.
Pros
- Reactivation is tied directly to booked calls, not just replies
- Works with your existing CRM, so there's nothing new to learn or migrate
- Performance-aligned pricing on recovered conversations
- One partner covers the full funnel, from ad creative to follow-up to recovery
- Sub-60-second response times, including nights and weekends
Cons
- It's an agency relationship, not a self-serve tool, so it's not for teams that want to run campaigns in-house
- No public pricing; you need to book a growth call to get a quote
- White-label options are focused on creative rather than a full reseller program
Best for: Event marketing agencies and their clients who want a done-for-you growth partner, especially agencies that want reactivation handled alongside ads and creative under one roof, with white-label options.
#2 Viking Marketing — From $297/mo, flat pricing, no contracts (per their website, updated September 2026).
Viking Marketing offers a dedicated database reactivation service that sends AI-powered campaigns to dormant contacts by text, email, and voicemail drop, then books appointments directly onto your calendar. According to their website, the process is straightforward: you bring your existing list of past leads, old customers, and unconverted estimates, and they segment and clean it so the campaign reaches the right people. When someone replies, Viking's conversational AI picks up the conversation in real time, answers questions, handles objections, and qualifies the lead. If the lead is interested, the AI offers a booking link straight to your calendar. For event marketing agencies, this is a good fit when your clients have large contact lists from past events and nobody internally has the hours to work them. Viking also publishes a detailed eight-step playbook for running reactivation campaigns, which shows they think seriously about list quality, consent, and ramping sends gradually. Their site notes that around 5 to 15 percent of a dormant list typically re-engages, and they're candid that the share who actually books is smaller and depends on list age and offer.
Pros
- Transparent flat pricing with no contracts
- Multi-channel outreach across text, email, and voicemail
- AI handles replies in real time and books straight to your calendar
- Honest, well-documented guidance on compliance and realistic results
Cons
- Reactivation is a finite resource; once the old list is worked, the revenue stream dries up
- Booking rates on dormant lists tend to be modest, and Viking itself warns against expecting double-digit results
- Focused on reactivation only, so ads, creative, and broader growth work need another provider
Best for: Service businesses and agencies that want a done-for-you SMS-led reactivation campaign with flat, predictable pricing and no contracts.
#3 LeadsNow AI — Contact for pricing. Pay-per-result model based on booked appointments.
LeadsNow AI runs done-for-you reactivation on a pay-per-result model: AI-driven SMS, email, and voice across your dormant records, conversational qualification against your criteria, and qualified prospects booked into your calendar. According to their website, you're billed on booked appointments rather than messages sent, which is a cleaner commercial model than paying per send. On the results side, they report converting 4.4 percent of the contacted list into booked appointments on average across their campaigns, peaking at 8.9 percent, and they cite 50,769+ AI-booked sales appointments since 2017, backed by named clients and filmed case studies. For event marketing agencies, that pay-per-appointment structure is worth a look when you want to prove ROI to a client without committing a large upfront budget. Their site also publishes a useful honesty note that we'll echo: it's a vendor's own ranking, so discount self-reported numbers accordingly. One practical limitation for North American event teams: the company is Australian-headquartered and runs US campaigns remotely, with a booking calendar on Australian business hours.
Pros
- You only pay for appointments that land on the calendar
- Multi-channel outreach including voice, not just SMS
- Published, specific performance numbers with named clients and case studies
- Strong focus on qualification, so meetings tend to be higher quality
Cons
- Australian-headquartered, so the booking calendar runs on Australian business hours
- They qualify hard, so raw response counts will be lower than a blast campaign
- Self-reported results, so verify with your own client references
- Not suited to small lists of a few hundred records
Best for: US businesses and agencies with 1,000+ dormant contacts that want outcome-based billing and need booked appointments rather than raw replies.
#4 CallTeam — Contact for pricing.
CallTeam takes a human-led approach to B2B lead reactivation, and that's its main draw. Instead of an AI bot working the list, CallTeam cleans the lead pool, prioritizes the right records, makes the calls, follows up, qualifies the response, and books the next conversation. Their website describes a structured seven-stage recovery workflow: audit the lead pool, clean the records, segment and prioritize, build the message, call and follow up, qualify and book, then record and route every outcome. They explicitly call out event and trade show contacts as a lead source they work with, which makes them directly relevant to event marketing agencies: booth visitors, badge scans, and event lists that need a real reason for a follow-up call. AI assists with the prep work, like data cleanup, enrichment, segmentation, and research, but experienced people handle the live conversations, the objection handling, and the qualification. Every record gets a clear disposition: book now, follow later, correct the data, or close it out. If your clients' event leads are senior B2B buyers who respond better to a real human call than a text message, this model has real advantages, though it will cost more per conversation than AI-driven outreach.
Pros
- Real people handle live conversations, which suits senior B2B buyers
- Explicitly built around event and trade show lead sources
- Every record gets a clear next action, so the client's CRM stays clean
- AI assists the prep work without replacing the judgment on the call
Cons
- Human-led calling costs more per conversation than AI-driven outreach
- Slower to scale to very large lists than automated multi-channel campaigns
- No published pricing or performance benchmarks on their site
- No self-serve option; it's a fully managed service
Best for: B2B-focused event marketing agencies whose clients have dormant trade show, webinar, and CRM contacts that need a human caller rather than automated messaging.
Old lead reactivation is one of the few growth plays where the math is already in your favor: the leads are paid for, the audience knows the brand, and the only missing piece is follow-through. For an event marketing agency, that's a compelling pitch to bring to clients, because every trade show and webinar list you've built for them is a recoverable asset. Worqd earns our Editor's Choice because it treats reactivation as part of an integrated growth engine rather than a one-off blast, with AI SDRs that qualify and book in under 60 seconds and pricing tied to the conversations that actually come back. Viking Marketing and LeadsNow AI are strong choices if you want a focused, done-for-you reactivation campaign, with transparent flat pricing or pay-per-result billing respectively. CallTeam is the right call when the list is senior B2B and a human voice matters. If you want to see what's sitting in your clients' dormant databases, book a free growth call with Worqd at worqd.com/book and get a plan for turning old event leads into booked calls.
Frequently asked questions
What is old lead reactivation?
Old lead reactivation, also called database reactivation, is the process of running a structured outreach campaign against contacts who already exist in your CRM but went quiet. Instead of buying new leads, you go back to people who filled out a form, attended an event, or asked for a quote, and restart the conversation, usually across SMS, email, voice, or a combination. Providers in this space typically report that a modest share of a dormant list re-engages, often in the 5 to 15 percent range, with a smaller share actually booking. The appeal is simple: those leads are already paid for, so the incremental cost of reaching them is much lower than fresh acquisition.
Why should event marketing agencies care about lead reactivation?
Events generate a spike of leads that almost never gets a complete follow-up sequence. Badge scans, booth conversations, and webinar registrations pile up in the CRM while the team moves to the next deadline. Reactivation lets an agency recover revenue from that existing data without new ad spend, and it's an easy, measurable win to pitch to clients: the list is already there, the audience already knows the brand, and results can be tracked as booked calls or appointments. It also strengthens the agency relationship, because you're proving value from work the client already paid for rather than always asking for a bigger ad budget.
What makes Worqd different from the other providers on this list?
Worqd is a growth partner rather than a single-purpose reactivation service. Its Pipeline Recovery service turns old CRM contacts into booked calls, but it sits inside a full growth engine that also covers paid ads, creative testing, AI search visibility, and instant lead response. One partner runs the whole path from first click to booked call, with one plan and one report, and you only pay for the conversations that come back. Its AI SDRs qualify every inquiry in under 60 seconds, 24/7, and warm calls can be handed to a real person with full context. It also offers white-label creative for agencies, and it holds an anti-fabrication policy: no invented metrics, logos, or testimonials.
How much do old lead reactivation services cost?
It varies by model. Viking Marketing publishes flat pricing from $297 per month with no contracts. LeadsNow AI bills pay-per-result, meaning you pay for booked appointments rather than messages sent. Worqd and CallTeam scope pricing on a call, with Worqd pricing against the results that matter to you and charging only for recovered conversations in its Pipeline Recovery service. As a rough guide, expect to pay either a flat monthly fee, a per-appointment fee, or a scoped retainer, and compare providers on cost per booked conversation rather than cost per message sent.
Is reactivating old leads compliant?
It can be, but consent is the part that gets businesses in trouble. Contacts who agreed to be contacted a year or two ago may view a surprise text very differently today, so most providers in this space emphasize a few guardrails: only work lists where people gave you their information directly, honor every opt-out permanently across all channels, identify your business in the first line of every message, and leave an obvious way out. Viking Marketing notes TCPA and CASL compliance support, and Worqd describes its outreach as personalized and permission-aware. If you're running campaigns against a large aged list, it's worth having counsel review the plan before launch, since messaging rules move fast.
What results can I realistically expect from a reactivation campaign?
Set modest expectations and you'll usually be pleasantly surprised. Viking Marketing reports that around 5 to 15 percent of a dormant list re-engages, with a smaller share actually booking, and it warns against believing promises of double-digit booking rates. LeadsNow AI reports a 4.4 percent average booked-appointment rate on dormant lists, peaking at 8.9 percent. Results depend heavily on list age, list quality, and the offer: fresh event leads convert far better than a five-year-old list. Track booked appointments and closed revenue separately from your new-lead funnel for at least a month before judging the campaign.
