Communication channels - email and SMS

When to send email, when SMS, and when both - practical guidance.

Updated 19.02.2026

You can send message templates via email, SMS, or both channels simultaneously. Each has its advantages - choose the right one for the situation.

Email - for longer messages

Email is the default communication channel:

  • No length limit - ideal for directions, detailed confirmations, studio rules
  • Attachments supported - photos, PDFs
  • Free - sending emails does not involve additional charges

Email works well for booking confirmations, post-session messages, and review requests.

SMS - for short, urgent messages

SMS arrives faster and is harder to miss:

  • 160 character limit - longer messages are split into multiple SMS
  • No attachments - text only
  • Instant delivery - the client will see the SMS even without internet
  • Additional cost - approx. 0.07-0.09 PLN per domestic SMS

SMS is ideal for reminders just before the booking (2 hours before) and urgent information about changes.

How to choose the channel in a template

When creating or editing a template, select:

  • Email only - standard choice for most messages
  • SMS only - for short reminders (e.g., 2h before session)
  • Email + SMS - for the most important messages (e.g., booking confirmation), when you want to be sure the client sees it

Practical recommendations

  • Booking confirmation - email (client needs details to keep)
  • 24h reminder - email + SMS (maximum effectiveness)
  • 2h reminder - SMS (client may not check email right before the booking)
  • Post-session / review request - email (not urgent)
  • Status change - email (informational)

What if...

  • Client does not have a phone number? SMS will not be sent, but the email will go normally.
  • SMS is too long? It will be split into multiple SMS. Each one is counted separately in costs.

Use SMS sparingly - for reminders and confirmations. Too many SMS messages can irritate clients. Email is sufficient for most communication.
