Klaviyo holds the list; the growth system reads the numbers and decides who is due.

You run Klaviyo and every send goes to the whole list, because nobody knows who is due. Klaviyo is the email and SMS platform. The growth system reads the campaign history beside the record's numbers, plans from both, then decides who is due and reads which send booked. Klaviyo keeps the list, the segments, the flows and the campaign history; your record keeps the visit history. The growth system builds a segment in Klaviyo from visit dates, so the comeback goes only to who is due. It answers the phone, books onto your calendar, writes consent back to Klaviyo and reports it on one page. Klaviyo stays.

What Klaviyo is for

Klaviyo is an email and SMS marketing platform. It holds the email list, the segments, the flows and the campaign history, and all of it stays there. The page for Klaviyo covers what stays in it, what is built around it and what the connection is.

A growth system reads the numbers first: revenue and margin by provider and by treatment from your record system, and which send booked from the Klaviyo campaign history. It builds the ninety-day plan from them. Then it adds the work around the list. A segment in Klaviyo is built from the visit dates in your record system and the flow is triggered from the booking. The call and the DM are answered and booked onto your calendar with the consent written back to Klaviyo, and the numbers go on one page. The full list is on the Klaviyo page; this page is about which job lives where and what a switch would cost.

The segment is the whole job

A list in Klaviyo knows who opened and who clicked. A record system knows who had which treatment and when. The growth system's one job on an email platform is to put the second fact into the first, as a segment that updates itself. Patients past their neurotoxin interval, patients who bought a series and have sessions left, members with no visit this month. Each becomes a segment in Klaviyo, rebuilt from the record system on a schedule, so a flow sends to the people who are due and to nobody else. The campaign history then answers the question an owner asks every month: which send brought a booking. The dashboard reads it and puts the answer beside the calls and the bookings.

When staying on Klaviyo is right

Stay on Klaviyo. A list with consent on record and a campaign history is an asset that took years to build, and the growth system is built to use it better. The booking stays on the calendar in your record system; the list stays in Klaviyo.

What a switch would cost you in time

Switching an email platform costs you the history and the warm-up. The list moves by export, but the consent records have to move with it in a form you can show later; confirm with counsel what your records must prove. Every flow is rebuilt. A new sending domain has to earn its reputation before sends land reliably. Two platforms run through the overlap, and the campaign history is split between them. Any remaining term on the agreement is a question for counsel. None of that tells you who is due.

How to do this on Monday

  1. Export last-visit dates by treatment from your record system. The list in Klaviyo knows who opened; the record knows who is due.
  2. Build one segment in Klaviyo: patients past their interval whose written consent to marketing messages is on record. What counts as consent is for counsel to confirm.
  3. Write one flow for that segment in the provider's voice: one message, one follow-up, then stop.
  4. Call your own number three times this week and note what a new patient would have heard.
  5. Read the campaign history for the last three sends and write down which one brought a booking. If you cannot tell, that is the dashboard's first job.

What to do next

NorthCore's Run the whole practice solution builds the growth system on top of Klaviyo: the answering, the comeback timing, the segmentation and the dashboard, and Klaviyo stays where it is. Scoped in writing and covered by the promise on this site: results in 90 days, or we keep working until you have them.

Have this built for your practice.

The comparison is the software. The numbers, the strategy and the system around it are what we build and run, scoped in writing. Results in 90 days, or we keep working until you have them.

Questions people ask.

Does Klaviyo do patient reactivation?

Klaviyo holds the email list, the segments, the flows and the campaign history, and your record system holds the visit dates. A growth system reads the dates, builds a segment in Klaviyo of the patients who are due, and sends one message and one follow-up in the provider's voice, then stops.

What does a switch away from Klaviyo cost in time?

Count it in the warm-up: the list exported with its consent records in a form you can show later, and every flow rebuilt. A new sending domain earns its reputation while two platforms run through the overlap. Confirm with counsel what your consent records must prove.

What is the difference between Klaviyo and NorthCore?

Klaviyo is software your team runs every day. NorthCore is a team that builds and runs the growth system on top of it: the answering, the comeback timing, the segmentation and the dashboard. One is the record; the other is the work around the record.

Will this send more email to my whole list?

No. It sends less, to more of the right people. A segment built from visit history gets one message and one follow-up, then stops; the rest of the list is left alone until they are due.
