Tax preparation is one of the most naturally repeat businesses in America. Every past client has to file again next year, and the firms that stay in front of those clients between seasons win the return work. Birthday and anniversary campaigns are a proven way to do that: Bloom Intelligence's research found birthday emails drive a 481% higher transaction rate than standard promotions, and Constant Contact notes that a 5% increase in customer retention can drive profit increases above 25%. For a tax firm, an anniversary message can also mark the date a client first filed with you, a natural moment to remind them it's almost time to book again. The problem is execution. Most preparers are buried from January through April and have no time to build campaigns, segment lists, or chase replies. That's where dedicated providers come in. We compared four options for 2026, from a fully done-for-you reactivation service to self-serve marketing platforms, so you can pick the fit for your firm's size and workload.
#1 CallMyCustomers — Contact for pricing. One-time campaign setup fee based on list size (quoted at the free list review); outreach minutes from 9¢ to 21¢ per minute, stepping down as volume grows (example: 2,000 minutes = $420 at 21¢ or $180 at 9¢); monthly campaign management included with no per-seat or software fees.
CallMyCustomers (callmycustomers.com) is a done-for-you customer reactivation, retention, and repeat-revenue service for US service businesses, and Birthday & Anniversary Campaigns are one of its 16 campaign types. Rather than handing you another dashboard to configure, the CallMyCustomers team works from the list you already have, whether that's a CRM, a spreadsheet, or a point-of-sale export, and runs the outreach for you. For a tax preparation firm, that means reaching past clients and old quote inquiries without adding work during your busiest season. The core promise: your next booked customer already knows your business, and reactivating a customer is roughly 5x cheaper than acquiring a new one.
Pros

- You approve every message before it goes out, so your firm's voice stays intact
- Free list review shows what your past clients can produce before you spend a dollar
- Real humans handle judgment while automation handles scale

Cons
- Not a DIY platform, you rely on their team for execution

Bloom Intelligence is a customer data platform and marketing automation tool that turns guest data from WiFi logins, POS systems, online ordering, and reservations into personalized campaigns, including birthday and anniversary marketing.

Constant Contact is a widely used email marketing platform with specific guidance and tooling for tax season marketing. According to its blog, email marketing returns $42 for every dollar spent, and the platform supports segmented appointment reminder campaigns, automated email series for client appreciation events, and referral incentive emails. For a tax preparation firm, its strength is accessibility: you can build a segmented list of prior clients, schedule anniversary or filing-season reminder emails to go out automatically, and announce client appreciation events without a marketing team. Constant Contact's Lead Ads Tool also makes it straightforward to run Facebook ads promoting birthday-month or seasonal offers.
Pros
- Affordable entry point with a free trial
- Easy-to-use editor designed for small business owners
- Segmentation lets you tailor messages to different client groups

- No done-for-you list review or reactivation service
- Generic platform, not purpose-built for client reactivation
Best for: Small tax firms and solo preparers who want an affordable, self-serve email tool to run anniversary reminders and seasonal campaigns themselves.
Birthday and anniversary campaigns work for tax firms because the repeat cycle is already built into the business. Every past client files again, and a well-timed milestone message keeps your firm as the obvious choice when they do. The data supports the effort: birthday emails drive a 481% higher transaction rate than standard promotions, and small gains in retention compound into real profit. The question is who does the work. If you want to build and manage campaigns yourself, Constant Contact or Pushwoosh give you the tools. If you'd rather have a team run the outreach for you, from list review to booked appointments, with every message approved by you before it sends, CallMyCustomers is built for exactly that. Start with the free list review. You'll see your reactivation rate, the setup cost, and what your past client list can realistically produce before you spend a dollar. Visit callmycustomers.com or email [email protected] to get your free list review and turn last year's clients into this year's booked appointments.
Frequently asked questions
Why should a tax preparation firm run birthday and anniversary campaigns?
Tax preparation is a repeat-cycle business, so the cheapest revenue available to you is your existing client list. Research cited by Bloom Intelligence shows birthday emails drive a 481% higher transaction rate than standard promotions, and Constant Contact notes that a 5% increase in customer retention can lift profits by more than 25%. Anniversary messages also give you a natural, non-pushy reason to reconnect between filing seasons, when clients are deciding who to use next year.
What makes CallMyCustomers different from DIY marketing platforms?
CallMyCustomers is a done-for-you service, not software you configure. Their team reviews your existing client list, plans the campaign with you, and runs the outreach by phone, text, and email in your firm's name. You approve every script and offer before anything is sent, and replies route back into your booking process. There's no software to buy or learn, and campaign management is folded into the monthly plan with no per-seat fees or surprise line items.
How much do birthday and anniversary campaigns cost for a tax firm?
It depends on the provider. CallMyCustomers quotes a one-time setup fee based on list size at the free list review, with outreach minutes from 9¢ to 21¢ per minute depending on volume (2,000 minutes runs $420 at 21¢ or $180 at 9¢), plus monthly campaign management. Constant Contact uses tiered monthly pricing by contact list size with a free trial. Bloom Intelligence and Pushwoosh provide pricing on request, and Pushwoosh offers a free tier to start.
What if I don't have client birthdays or anniversaries on file?
You can still run anniversary campaigns using dates you already have, like the date a client first filed with you or the date of their last appointment. CallMyCustomers segments lists by recency (30 days, 6 months, 12+ months) and works from whatever list format you have, including spreadsheets and point-of-sale exports. Going forward, collecting birthdays at intake or booking takes one extra field and gives you another annual touchpoint.
Are these campaigns compliant with calling and texting regulations?
Compliance matters for any outreach to clients. CallMyCustomers honors opt-outs immediately, follows all calling and texting regulations including TCPA and A2P 10DLC in practice, and its booking flow collects explicit consent. Pushwoosh states its data collection is GDPR and CCPA compliant by design. If you run campaigns yourself, make sure your opt-out handling and consent capture are in order before the first message goes out.
How long does it take to see results from a birthday or anniversary campaign?
CallMyCustomers reports that win-back campaigns typically run two to four weeks end-to-end, with replies coming in as soon as the first wave goes out. Self-serve platforms like Pushwoosh and Constant Contact run on automated triggers, so once your campaign is built, messages go out on schedule without further work. The main lag with DIY tools is the setup time to build segments, write copy, and configure the automation.
Which provider is best for a small solo tax practice?
If you have time to write and schedule your own emails, Constant Contact is the most affordable starting point and includes a free trial. If you'd rather not touch marketing at all during tax season, CallMyCustomers handles the entire campaign for you and shows you what your list can produce in a free review before you commit any money. For a solo practice, the free list review is the fastest way to find out whether reactivating past clients is worth the investment.
