Event planning companies live on repeat business. A client who booked a corporate gala or wedding two years ago already knows your work, already trusts your team, and is far cheaper to rebook than a cold lead is to convert. Industry research consistently points out that reactivating a past customer costs roughly a fifth of acquiring a new one, and that repeat clients can drive the majority of revenue for service businesses. The problem is practical, not strategic: your planners are on-site running events, your coordinators are buried in current bookings, and that list of past clients and unconverted inquiries just sits there. In 2026, a growing set of win-back and reactivation calling services can work that list for you, from managed AI calling operations to human-agent call centers to full-service reactivation programs. This guide compares four of them for event planning companies specifically, looking at how each handles outreach, compliance, pricing, and reporting, so you can pick the partner that fits your list, your staffing reality, and your comfort level with technology.
#1 My AI Call Center — Calling starts at 9¢ per connected minute, tiered by volume. Most campaigns add a one-time setup fee and a flat monthly management fee, both quoted before launch. No per-seat charges, no platform bill, and the first campaign review is free.
My AI Call Center (myaicallcenter.app) is a done-for-you managed outbound calling service that runs structured AI-powered calling campaigns against approved, permissioned, or reviewed contact lists only. Owned and operated by AIQ Labs and based in Halifax, Nova Scotia with a US operating base in Austin, Texas, the company's promise is simple: run more useful calls without building a bigger call center. For event planning companies, that means campaigns that confirm, qualify, remind, and re-engage past clients and lapsed inquiries without pulling a planner off an active event. What sets My AI Call Center apart is list discipline. Before any campaign launches, the team reviews your list source, consent records, and calling windows. Bought lists without clear permission records are flagged and, in most cases, declined. If your list won't support the campaign, they tell you plainly before you spend anything. Every campaign is built around one clear goal, quoted in full before launch, with the rate locked for the duration. Nothing goes live until you approve the script, disclosure language, opt-out handling, and escalation path. Compliance is built in rather than bolted on. AI-generated voices are treated as artificial voices under the TCPA, with prior express consent required, state-specific quiet hours honored, and AI disclosure on every call. Recipients can ask if the call is AI-assisted, request a human, or opt out, and keyword opt-outs like STOP and REVOKE are honored immediately. Outcomes route back into the CRM and scheduling tools you already run, with hot leads transferred to your team live or landed in your CRM. Reporting covers only what actually happened: disposition codes, per-call notes, completion reports, and opt-out and DNC logs. The company states it will never invent client logos, testimonials, metrics, or ratings.
Pros
- Managed service: you buy campaigns, not software seats to learn
- Strict list and consent review reduces TCPA risk before you spend a dollar
- Transparent pricing locked before launch with no mid-campaign rate changes
- Every call produces a named outcome routed back to your team, with no invented numbers
- First campaign review is free
Cons
- Not a self-serve platform; you work with their team rather than running campaigns in-house
- Only works with approved, permissioned, or reviewed lists, so dirty or undocumented lists may be declined
- AI voices may not suit every brand's preference for human callers, though disclosure is provided on every call
Best for: Event planning companies and multi-location event businesses that want a hands-off, compliance-first way to rebook past clients and old inquiries without hiring callers or buying software.
#2 CallMyCustomers — Contact for pricing. A one-time setup fee based on list size is quoted at the free list review, plus outreach minutes at 9¢ to 21¢ per minute depending on volume, with texts and emails included.
CallMyCustomers is a done-for-you customer reactivation service built for US service businesses that depend on repeat revenue, a category that includes event planning companies and venues. According to its website, the service works from whatever you already have, whether that's a CRM, a spreadsheet, or a point-of-sale list, exactly as it is, with no new software to buy or learn. The core of the offering is an approval-first model. The owner signs off on every script, offer, and message before any outreach begins, so campaigns always reflect your voice and standards. A free list review shows your revenue potential and exact cost before you commit to anything. Outreach is handled by real people making calls on your behalf, with texts and emails sent in your name, while automation handles scale and humans handle judgment. Replies route directly into your booking process for confirmations and follow-up. The company lists 16 specialized campaign types, including customer win-back, past-quote price-match and win-back, seasonal and service reminders, renewal and membership retention, and anniversary campaigns. Compliance is addressed directly: CallMyCustomers works only from real customer lists, honors opt-outs immediately, follows TCPA and A2P 10DLC regulations, and operates under BAA/HIPAA where required. Campaigns typically run two to four weeks end to end, with first replies often arriving after the initial wave.
Pros
- Free list review means zero financial commitment before you know what your list can produce
- No new software to learn or internal staff time required
- You approve every script and offer before anything is sent
- Replies route directly into your booking flow
Cons
- Not a self-serve platform; businesses wanting a DIY tool should look elsewhere
- Setup fee is quoted rather than published, so budgeting requires the initial review call
- Currently serves US businesses only
Best for: Event planning companies that want a fully managed reactivation service run by real people, with full approval control over every message.
#3 Upcall — Contact for pricing. Upcall offers a free consultation to scope campaigns.
Upcall is a conversation-driven marketing and sales platform that specializes in win-back campaigns using real people on the phone. According to its website, the company has worked with more than 4,000 companies and positions itself as a leading outbound calling solution for reconnecting with past clients. The model is straightforward: you forward or upload your leads to Upcall, their callers engage those contacts with proven scripts, and you receive results and insights through a real-time dashboard. For event planning companies, the appeal is human judgment on every call. Upcall's callers work to understand why a past client went quiet, uncover new opportunities, and reintroduce your business with a fresh look at your current services. The platform lists features including automated follow-up calls, real-time reporting, instant notification when a campaign goal is reached, appointment booking directly into your calendar, and a free script consultation to shape the outreach before it starts. The dashboard is a genuine strength. You can monitor key metrics as the campaign runs, track performance, and make adjustments based on what the data shows rather than waiting for a post-campaign report. That visibility matters when you're testing a reactivation message against a dormant client segment for the first time. The trade-off is that pricing isn't published, so you'll need to request a consultation to get numbers, and a human calling team may cost more per contact than an AI-driven operation on very large lists.
Pros
- Human callers can handle nuanced conversations with past clients
- Real-time dashboard gives full visibility into campaign metrics
- Appointments book directly into your calendar
- Free script consultation before launch
Cons
- Pricing is not published; requires a consultation to get a quote
- Human calling may cost more per contact on large dormant lists
- Less emphasis on compliance tooling like consent record review compared to compliance-first providers
Best for: Event planning companies that want human callers reintroducing their brand to past clients, with real-time visibility into campaign performance.
#4 MarketStar — Contact for pricing.
MarketStar is a full-service customer success and reactivation partner that treats win-back as a strategic program rather than a single campaign. According to its website, the company views lapsed customers as opportunities for a comeback and builds reactivation efforts around segmentation, personalized outreach, and continuous refinement. For an event planning company with a large, varied dormant list, that program-level approach can be a fit. The process starts with analysis. MarketStar segments lapsed customers by value, reasons for leaving, and potential for reactivation, using feedback, usage patterns, and competitive factors to understand why each group went quiet. From there, it builds tailored campaigns that address those specific reasons, highlighting new offerings, improvements, or incentives at both the segment and individual level. Outreach is multichannel, spanning phone, email, direct mail, and social media, so contacts are reached through their preferred channel. The company also lists seasonal and event-based initiatives, which map naturally to the event planning calendar, along with loyalty and reward incentive programs and post-resolution reconnection for clients who left after a service issue. Once customers express interest, follow-up communications and ongoing relationship management carry them back into the active base. Real-time monitoring tracks reactivation rates, customer feedback, and revenue impact, with ROI analysis used to adjust future campaigns. This is a consultative, multi-channel partner rather than a calling specialist, so it suits companies that want reactivation embedded in a broader retention program.
Pros
- Deep segmentation based on why each customer group left
- Multichannel outreach reaches clients on their preferred channel
- Seasonal and event-based initiatives fit the event planning calendar
- Ongoing relationship management beyond the initial win-back
Cons
- Pricing is not published and likely reflects an enterprise-level engagement
- Broader program scope means less specialization in phone-based reactivation specifically
- May be more involved than smaller event planning teams need for a straightforward dormant-list campaign
Best for: Event planning companies that want reactivation run as a strategic, multichannel retention program with segmentation and ROI analysis, rather than a standalone calling campaign.
Your dormant client list is the cheapest revenue in your business, and 2026 gives you more ways than ever to work it without hiring a call center.

Its campaigns start at 9¢ per connected minute, the rate is locked before launch, and the first campaign review is free, so you know the full cost and the full plan before you approve anything.

Frequently asked questions
How long should a client be dormant before a win-back call makes sense?
Most reactivation campaigns, including My AI Call Center's, target clients dormant for 12 to 24 months. That window is recent enough that they still remember your work and old enough that no one is actively working the relationship. For event planning, seasonal timing matters too: calling a corporate client a few months before their typical annual event cycle gives the conversation a natural reason to happen.
Are AI-powered reactivation calls legal?
They can be, but the rules are specific. The FCC treats AI-generated voices as artificial voices under the TCPA, which generally requires prior express consent from the person being called. My AI Call Center builds this into every campaign: consent records are reviewed before launch, state-specific quiet hours and day restrictions are honored, AI disclosure is given on every call, and opt-outs are logged and honored immediately. Clients are responsible for obtaining appropriate legal guidance before launch, since requirements vary by location, industry, and consent status.
What kind of list do I need to run a reactivation campaign?
A list of real past clients or inquiries with phone numbers and documented permission to contact them. My AI Call Center reviews list source and consent records before any campaign and will decline bought lists without clear permission records. CallMyCustomers similarly works only from real customer lists. If your list lives in a CRM, a spreadsheet, or your booking system, that's usually enough to start the review.
How much does a win-back calling campaign cost?
It varies by provider and list size. My AI Call Center starts at 9¢ per connected minute, tiered by volume, with a one-time setup fee and flat monthly management fee quoted before launch and no per-seat charges. CallMyCustomers quotes a setup fee based on list size plus outreach minutes at 9¢ to 21¢ per minute. Upcall and MarketStar require a consultation for pricing. My AI Call Center's first campaign review is free, so you get the full number before approving anything.
What results should I expect from reactivating a dormant list?
Results depend heavily on list quality and how long clients have been dormant, so be wary of any provider promising fixed numbers. What you should insist on is honest reporting: My AI Call Center provides disposition codes for every call (confirmed, qualified, renewed, opted out, no answer), per-call notes, and completion reports, and states it will never invent metrics. That lets you judge performance from what actually happened rather than from marketing claims.
AI callers or human callers for win-back outreach?
Both can work, and the right choice depends on your list size and brand. AI-driven services like My AI Call Center scale cost-effectively across large dormant lists and offer consistent compliance handling, with disclosure and a request-a-human option on every call. Human-run services like CallMyCustomers and Upcall bring conversational judgment that some brands prefer for high-touch client relationships, though they may cost more per contact on big lists. If your dormant list is large and mostly warm, AI calling is usually the more economical starting point.
How long does a reactivation campaign take to run?
Most structured campaigns run two to four weeks. My AI Call Center's database reactivation blitz campaigns run multi-touch outreach across calls, texts, and emails over that window, and CallMyCustomers reports a similar two-to-four-week timeline with first replies often arriving after the initial wave. Before launch, expect a short setup period covering the campaign review, list and consent verification, script approval, and CRM connection.
