What list size is normal for a medspa?

Many medspas sit in the 500–10,000 range, with stronger operators sometimes reaching 20,000–30,000. At these sizes, you can usually find a platform that’s easier and more cost-effective without sacrificing professional features.

Email Marketing for Medspas: Best Platforms + Pricing

Medspa email marketing (real-world list sizes)

Most medspas aren’t collecting hundreds of thousands of emails. The “normal” range we see is closer to 500 to 30,000 contacts — and at that size, the best platform is usually the one that makes it easy to: capture leads, send 1–4 emails/month, and run a simple welcome sequence without turning marketing into a second job.

This guide compares the most common tools medspas use (Mailchimp and Constant Contact) alongside lower-cost, medspa-friendly options like MailerLite, Sender, and Brevo — plus a quick reality check on beehiiv (popular, but usually not a medspa fit).

Why MailerLite Wins for Most Medspas

Best overall

MailerLite = easiest path to “lead capture + newsletter + automation”

Most medspas don’t need complex funnels. They need a platform that makes it painless to capture emails, send consistent campaigns, and automate a short welcome sequence that educates new leads (without your team rebuilding things every month).

Built-in forms + landing pages Simple automations that actually run Fits 500–30k list sizes Clean UI (less “tool fatigue”)

If you want campaign ideas and plug-and-play content, pair your platform with your content system: Medspa Mastery Email Content.

Platform Breakdowns (Medspa Use Case)

Mailchimp (common starting point)

Familiar, easy to start, and widely used — which is why many medspas begin here. The downside is that pricing can rise as your database grows, especially if you’re keeping old contacts you can’t email.

Easy to use Good templates Can get pricey

Constant Contact (traditional option)

Straightforward for newsletters and less intimidating for teams that want something “classic.” If you don’t need heavy automation, it works — it’s just not usually the lowest-cost option.

Simple Automation is basic Often higher cost

Sender (best budget)

Great when you want the essentials — capture forms, campaigns, and basic automation — without paying “brand tax.” Ideal for many single-location medspas and newer clinics.

$ Lowest cost feel Solid capture tools Easy setup

Brevo (good for larger lists)

Often a strong value when your list grows and you don’t send constantly. Slightly more “platform-y” than the simplest tools, but very workable once set up.

Good for 10k–30k Flexible pricing model More setup

beehiiv (popular, but usually not a medspa fit)

Beehiiv is awesome for creator-style newsletters. But medspas typically need promotion-friendly campaigns, segmentation, and lead-capture-to-follow-up workflows. If your goal is bookings + retention (not “media brand newsletter growth”), a traditional email marketing platform is usually the better choice.

Easy to publish Limited automation Not built for promos

If You Switch: Time, Steps, and the “Don’t Break Your Forms” Checklist

Typical time investment: 2–4 hours

Most medspas can switch platforms in one focused afternoon. The biggest time-sink isn’t the emails — it’s swapping lead capture forms across the website and recreating automations.

1

Export your contacts
Download subscribed contacts (and tags/segments if available). If you’re leaving Mailchimp, plan a quick cleanup so you’re not paying for old “ghost contacts.”
2

Choose your new platform + create your lists/segments
Medspa-friendly segments: Injectables, Skin, Laser, Membership, Leads (never booked), and VIP/High frequency.
3

Import contacts + map fields
Map first name, phone (if stored), lead source, last appointment date, etc. Keep it simple.
4

Rebuild your lead capture
Update website forms, popups, and landing pages. This is the step that prevents “we stopped collecting leads for 2 weeks and nobody noticed.” Reference your services setup here: Newsletter Services.
5

Recreate your automations (minimum viable)
Start with: Welcome series (2–4 emails), Post-consult follow-up, Reactivation (90–180 days no booking). For ideas: Email Content.
6

Authenticate your sending domain (deliverability)
Add SPF/DKIM records in DNS to protect inbox placement. Most platforms provide step-by-step instructions.
7

Warm up your sending
First send to your most engaged subscribers (opened/clicked recently), then expand. Avoid blasting the full list on day one.

FAQ: Email Marketing Platforms for Medspas

What’s the best email marketing platform for most medspas?

For most medspas with 500–30,000 contacts, the best fit is the platform that makes it easiest to capture leads, send 1–4 campaigns per month, and run a simple welcome sequence. Many medspas choose MailerLite for usability, or Brevo if they have a larger list and don’t email constantly.

Is beehiiv a good choice for medspa email marketing?

Beehiiv is excellent for creator-style newsletters, but medspas usually need stronger segmentation, promotion-friendly campaigns, and lead-capture-to-follow-up workflows. For most service businesses, a traditional email platform is typically a better match than a newsletter-first platform.

How long does it take to switch from Mailchimp or Constant Contact?

Most medspas can switch in about 2–4 hours. The time goes into exporting/importing contacts, replacing website signup forms, recreating welcome emails, and authenticating your domain for deliverability.

What do I need to rebuild when I switch platforms?

Plan to rebuild your signup forms/popups, landing pages (if used), and automations like welcome emails and follow-up sequences. Email templates can usually be copied over quickly.

Will switching platforms hurt deliverability?

Not if you authenticate your domain (SPF/DKIM), import only engaged contacts, and warm up sending by emailing your most engaged subscribers first before expanding to your full list.

What’s the simplest setup a medspa should have?

At minimum: one high-converting signup form, one welcome sequence (2–4 emails), and one monthly newsletter or offer email. Consistency beats complexity.
