A warm welcome your patients feel

A kind first visit, then only robotic reminder texts.

Patients choose a practice for how it feels, and most of what they hear afterwards is "Reply C to confirm". A short letter from the front desk, with their name and a real welcome, is a small thing that people remember when a friend asks for a recommendation.

Questions people ask

What should these letters say?

Keep them warm and non-clinical. Welcomes, thank-yous, birthdays and holiday notes work well. Treatment details, results and anything clinical belong in your practice system, not in a letter.

We have strict data rules. Can we use it?

Practices with specific requirements usually look at Private Deploy, which runs on your own web address and sends through your own mail server, with your data on your system. We go through your requirements before a pilot.

Is it really handwritten?

No, and we never say it is. Each letter is set in one of 60 handwriting fonts you choose, on letter paper inside an envelope that tears open on screen. It reads like a handwritten note and arrives in seconds.

Do they need an app or an account?

No. The letter arrives as a link by email and opens in any phone or computer browser. You can see when each one is opened.

Can we add a photo of our team and a voice note?

Yes. Add a photo, a voice note of up to 60 seconds and music. On the Business plan letters carry your practice name and no GreetSpark branding.

What does it cost?

You can try three letters a month for free. Business is $39 a month for 500 letters, sent from your own email address.

Three letters a month are free. No app for anyone, nothing to install.
