Most mortgage brokerages pour their budget into finding new borrowers while the clients they already closed quietly drift away. The numbers behind that habit are uncomfortable. Roughly 4 in 5 mortgage customers go to a different lender for their next loan, according to MonitorBase, and most customers forget a business they haven't heard from within about 12 months. Meanwhile, reactivating a past client costs around 5 times less than winning a new one. That gap is exactly why borrower retention and renewal-focused outreach tools have become a serious line item for brokerages in 2026. The four providers below approach the problem differently. Some use predictive data to flag borrowers who are about to shop around. Others run automated homeowner content to keep you top of mind. And one takes a fully done-for-you approach, running approved calls, texts, and emails to past clients and inactive members on your behalf. Here's how they compare, so you can pick the fit for how your brokerage actually works.
#1 CallMyCustomers — One-time Campaign Setup fee based on list size (quoted at the free list review), plus Outreach Minutes at 9¢–21¢ per minute depending on monthly volume. Campaign management is folded into the plan, and texts and emails are not billed separately.
CallMyCustomers is a done-for-you reactivation and retention service built for businesses that live on repeat work, and it treats renewal and membership retention as a campaign you can switch on rather than software you have to learn. The pitch is simple: your next booked customer already knows your business. Instead of buying another dashboard, you hand over your existing list, whether that lives in a CRM, a spreadsheet, or your point-of-sale system, and their team segments it by recency, old quotes that never closed, expiring memberships, and happy customers who could refer. Then they run the outreach for you, calling on your behalf and sending texts and emails in your name, with replies routed back into your booking process.
Pros
- Free list review means you see the potential before spending a dollar
- You approve every script, offer, and message, so outreach stays on brand
- No software to buy or learn; it works from the list you already have
- Flat, transparent pricing with no per-seat fees or surprise line items
- Campaigns typically run two to four weeks, with replies as soon as the first wave goes out
Cons
- It's a service, not a self-serve platform, so you can't log in and run campaigns yourself
- Best suited to businesses with an existing customer or member list to work from
- Outreach minutes are usage-based, so costs scale with call volume
Best for: Mortgage brokerages and other US service businesses that want past clients and expiring memberships worked by a real team, with full approval control, and without adding another software subscription.
#2 MonitorBase — Contact for pricing
MonitorBase positions itself as the leader in borrower retention technology for the mortgage industry, and its starting statistic explains why brokerages pay attention: according to the company, 4 in 5 mortgage customers go to a new lender for their next loan. The platform serves mortgage lenders, banks, credit unions, and brokers with a Borrower Retention System built around predictive scenarios and alerts. The idea is to identify which past borrowers are showing signs of re-entering the market before they start shopping, so you can reach out at the right moment with the right message. For a brokerage trying to protect its book of business from quiet attrition, that early-warning approach addresses the core retention problem directly.
Pros
- Purpose-built for the mortgage industry rather than a generic retention tool
- Predictive alerts let you engage borrowers before they shop around
- SoftPull credit checks provide concrete market re-entry signals
- CRM integration keeps retention data connected to your workflow
Cons
- Pricing is not published, so you'll need to contact sales for a quote
- Requires your team to act on alerts; outreach execution stays in-house
- Software-based, so there's a learning curve and a system to maintain
Best for: Mortgage brokerages and lenders that want data-driven early alerts when past borrowers show signs of shopping for a new loan.
#3 Milo — Contact for pricing
Milo markets itself as a system that transforms past clients into a repeat and referral engine for mortgage lenders, with its borrower retention operating on autopilot. According to its profile, the platform engages clients monthly with interactive content and monitors their online activity for indicators that they're re-entering the market, which lets you reach out at what the company describes as the precise moment they're needed. That combination is worth understanding. The monthly content keeps you top of mind between transactions, while the activity monitoring gives you a trigger for a personal conversation when a past client may actually need a loan again. For brokerages that don't have time to build nurture campaigns themselves, the automated content layer does a lot of the heavy lifting.
Pros
- Automated monthly content keeps past clients engaged without manual effort
- Activity monitoring adds a timely trigger for personal outreach
- Designed to drive both repeat loans and referrals
- Set-and-forget model suits busy loan officers
Cons
- Pricing is not publicly listed
- Automated content is less personal than human-run outreach
- You still handle the actual outreach conversations when signals fire
Best for: Mortgage lenders and brokerages that want always-on, automated nurture of their past client database with signal-based outreach triggers.
#4 Stikkum — Contact for pricing
Stikkum bills itself as an easy-to-use, plug-and-play mortgage retention platform, and its onboarding speed is the headline: according to its listing, you can sign up in minutes and be live in 72 hours, with 7-day customer support. The platform focuses on automating outreach, staying ahead of client shopping behavior, and protecting your pipeline with real-time alerts that drive repeat business. For a smaller brokerage that has been meaning to set up a retention program but keeps putting it off, the fast setup removes the usual excuse. The trade-off is that it's a platform you run, so someone on your team owns the campaigns and follows through on the alerts it surfaces.
Pros
- Fastest time to live of the platforms here, at 72 hours
- Real-time alerts on shopping behavior help you intervene early
- 7-day support is more available than typical weekday-only support
- Simple, plug-and-play design keeps the learning curve short
Cons
- Pricing is not published publicly
- Your team still runs the outreach the platform automates
- Fewer documented features available in public listings than some competitors
Best for: Mortgage brokerages that want a quick-to-launch retention platform without a long implementation cycle.
Retention math is hard to argue with. Reactivating a past client costs about 5 times less than acquiring a new one, and for many service businesses, roughly 60% of revenue comes from repeat customers. The catch is that retention only works if someone actually does the outreach, and that's where most brokerages stall. If you have the staff and the discipline, a predictive platform like MonitorBase or Milo can surface the right borrowers at the right time. If you'd rather have the work done for you, CallMyCustomers starts with a free list review, shows you what your past client and membership list can produce, and then runs approved calls, texts, and emails on your behalf, routing replies straight into your booking process. Either way, the borrowers and members who already know you are the cheapest growth you'll find in 2026. Get your free list review and turn the clients you've already served into your next booked pipeline.
Frequently asked questions
What makes CallMyCustomers different from mortgage retention software?
It's a done-for-you service rather than a platform. Their team segments your list, runs the calls, texts, and emails in your name, and routes replies into your booking process. You approve every script, offer, and message before anything goes out, and there's no software to buy or learn. Predictive tools tell you who to call; CallMyCustomers actually makes the calls.
How much does borrower retention software cost?
Most mortgage-specific retention platforms in this list, including MonitorBase, Milo, and Stikkum, don't publish pricing, so you'll need to request a quote. CallMyCustomers quotes a flat one-time Campaign Setup fee based on list size at its free list review, plus Outreach Minutes at 9¢ to 21¢ per minute depending on monthly volume, with campaign management and all texts and emails folded into the plan.
Why should a mortgage brokerage invest in retention instead of just more lead generation?
Because the economics favor it. Research cited across the industry shows reactivating a past customer costs about 5 times less than acquiring a new one, and roughly 60% of revenue for many service businesses comes from repeat customers. MonitorBase also reports that 4 in 5 mortgage customers switch lenders for their next loan, which means most brokerages are losing repeat business they could keep with consistent outreach.
How quickly can I see results from a retention campaign?
CallMyCustomers win-back campaigns typically run two to four weeks end to end, with replies often coming in as soon as the first wave of outreach goes out. Stikkum gets you live within 72 hours of signing up. Predictive platforms like MonitorBase work on an ongoing basis, surfacing signals as past borrowers re-enter the market.
Is this kind of outreach compliant with calling and texting regulations?
It needs to be, and CallMyCustomers treats compliance as part of the service: it works only from lists of real customers, honors opt-outs immediately, follows calling and texting regulations including TCPA and A2P 10DLC in practice, and collects explicit consent during the booking flow. If you run outreach in-house through another platform, make sure your team covers the same ground.
Do I need a big customer database for retention campaigns to work?
You need a real list of past clients or members, but it doesn't have to be large or clean. CallMyCustomers works from a CRM, spreadsheet, or point-of-sale list exactly as it is, and the free list review tells you what your list can realistically produce before you spend anything. Even a few hundred past clients can be worth working systematically.
Can these tools help with referrals as well as renewals?
Yes. Milo is positioned around turning past clients into repeat and referral business, and CallMyCustomers runs dedicated Referral & Repeat-Visit campaigns and a Structured Referral Program Engine alongside its renewal and win-back campaigns, so one list can feed multiple revenue streams.
