Most medspa marketing conversations start with acquisition: Google ads, social posts, influencer partnerships. These matter. But the arithmetic of a medspa business — high acquisition cost, high lifetime value, a treatment cycle that naturally drives repeat visits — means retention marketing almost always delivers a higher return per dollar than acquisition.
A client who books a Botox appointment and gets no follow-up for six months is a client who's actively being recruited by your competitors. The treatment is wearing off, they're noticing it, and whoever gets in front of them first wins the rebooking. That can be you or it can be someone else.
Email vs. SMS: when to use each
Both channels have a place. The choice is not either/or; it's which message belongs on which channel.
Email is better for:
- Longer-form content — seasonal promotions, service spotlights, treatment education
- Visual campaigns — before/after imagery, spa photography, branded templates
- Newsletters and digests — monthly updates, what's new, product launches
- Winback campaigns — lapsed clients who haven't booked in 90–180 days
- Pre-appointment preparation instructions (longer copy)
SMS is better for:
- Time-sensitive offers — "this week only" fills for open slots
- Re-engagement for clients whose treatment is about to lapse (12-week Botox reminder)
- Appointment confirmations and 24-hour reminders
- Direct conversational booking — the AI SMS agent discussed in a separate post
- Membership renewal nudges (one-line, direct)
HIPAA and marketing consent: the rules that apply
Email and SMS marketing to medspa clients sits at the intersection of two compliance frameworks: HIPAA and TCPA. They are separate, and confusion between them is one of the most common compliance mistakes medspa operators make.
HIPAA and marketing. Under the HIPAA Privacy Rule, using PHI to market to patients requires either an authorization or a very narrow exception. If you send a "come back for your Botox touch-up" email to a specific client because your CRM knows they had Botox — that is using PHI for marketing, and it requires explicit authorization unless your BAA covers it under treatment communications. Most medspa CRMs handle this by categorizing reminders as "treatment-related communications" (covered) vs. "promotional marketing" (requires opt-in). The distinction matters operationally: a re-engagement email about a service the client has had before is different from a promotional email about a new service.
TCPA and SMS consent. The Telephone Consumer Protection Act requires prior express written consent before sending marketing text messages. Booking a client does not automatically consent them to promotional SMS. Best practice: collect a separate "I consent to receive marketing texts" checkbox at booking, document the timestamp and source, and honor opt-outs immediately. Transactional SMS (confirmations, reminders, clinical follow-up) operates under a different consent standard.
The five campaigns every medspa should have running
1. The 90-day lapsed client
Every client who hasn't booked in 90 days and has a history of at least two visits is a winback candidate. Email first with a specific, personalized subject line referencing the service type (not "we miss you" — that pattern has a 2% click rate). Follow with SMS if no open at 72 hours. Include a direct booking link and, where appropriate, a limited-time offer for existing clients.
Typical results in the medspa vertical: 12–18% re-book rate from lapsed clients reached by both channels.
2. The treatment-cycle reminder
Botox results typically last 10–12 weeks. Fillers, 6–18 months depending on product and area. Laser packages run 4–8 sessions. Your CRM knows when a client's last treatment was. An automated SMS at 10 weeks for Botox clients — "Your results will start fading around now. Want to get ahead of it?" — converts at significantly higher rates than a generic promotion because it's factually relevant to where the client is physically.
3. The birthday campaign
Clichéd but effective, because it's personal and the offer timing is natural. Birthday month email with a client-exclusive offer. A 15% discount on their most-booked service, or a complimentary add-on. Keep the copy short and the offer specific. "Happy birthday, here's 15% off your next facial this month" outperforms elaborate creative every time.
4. The package balance nudge
Clients who bought a 6-session laser package and have used 2 sessions six months ago are a specific, high-value segment. They've already paid. They just haven't come back. An SMS that says "You have 4 sessions left on your laser package — want to schedule your next one?" converts because there's no purchase decision required, just a calendar action.
5. The membership renewal
If you run memberships, the renewal window — typically the week before and the day before renewal — is the highest churn-risk moment. A proactive email explaining what the membership includes, what the client has used in the current cycle, and what's available to them in the next cycle reduces voluntary cancellation meaningfully. Include a direct link to the client portal where they can manage their membership.
The content calendar: what to send and when
For a practice without a full-time marketing person, a sustainable email calendar looks like:
- Monthly newsletter — what's new, any seasonal services, provider spotlight. 400–600 words. Send the first Tuesday of each month.
- Quarterly promotion — meaningful offer tied to a natural event (New Year, spring refresh, holiday packages). Not more than four per year or the urgency evaporates.
- Ad-hoc slot-fill SMS — when you have last-minute cancellations, a broadcast to clients who have expressed interest in that service. Keep it short: "Opening Monday at 2pm for Botox — first to reply gets it."
Automated campaigns run in the background at whatever cadence makes clinical sense for each trigger.
Segmentation: the difference between spam and marketing
The most common reason medspa email campaigns underperform is sending the same message to everyone. A client who has only ever had facials should not receive an injectable promotion. A client who purchased a 10-session laser package last month does not need a "try laser" email.
The minimum useful segments for a medspa:
- By last visited service category (injectables, laser, facials, body)
- By recency (booked in last 30 days / 31–90 days / 90+ days lapsed)
- By active packages or memberships
- By channel consent (email only / SMS only / both)
- By new vs. returning client
Cross those segments and you have meaningful targeting. A "lapsed injectable client with no active package, email consent" is a distinct audience with a specific message that will land.
What the platform needs to support this
These campaigns are not hard to design. The execution challenge is always data access: does your marketing tool know who has an active package, when their last appointment was, which services they've had, and whether they've opted into SMS?
Most medspas running on Mindbody, Vagaro, or Boulevard end up exporting CSVs to Mailchimp, Klaviyo, or another email tool, reconciling data by hand, and losing the real-time precision that makes these campaigns work. A client who books at 10pm via the AI SMS agent won't be in next week's Mailchimp import — so the "don't send to recently booked clients" suppression list is always stale.
Lumè's marketing campaigns run against live CRM data — the same database that holds the appointments, packages, memberships, and consent flags. When a client books, they're immediately removed from the "lapsed" segment. When a package is redeemed, the balance updates in real time. No CSV exports, no stale lists, no double-sends to clients who booked yesterday.
