It depends on your goal, but for appointment reminders, SMS is usually better if you want the highest chance people will see it.

Quick comparison

SMS

  • Pros: Very high open rate, usually read quickly, good for short reminders and same-day alerts
  • Cons: More expensive, character limits, needs phone number consent
  • Best for: Time-sensitive reminders, no-show reduction, short confirm/cancel messages

Email

  • Pros: Cheaper, can include more detail, links, attachments, directions, prep instructions
  • Cons: Lower open rate, may be delayed or missed
  • Best for: Full confirmation messages, detailed instructions, non-urgent reminders

Best practice

For most businesses, the best approach is:

  • Email for the initial confirmation and detailed information
  • SMS for the reminder closer to the appointment

Simple rule

  • If the reminder is important and time-sensitive: use SMS
  • If you need to send more details: use email
  • If you want the best results: use both

If you want, I can help you choose based on your industry, budget, and how far in advance you send reminders.

Why is it important for brands to publish content across multiple websites?

Publishing across multiple trusted sites increases the chance that your brand appears in the citations LLMs draw from when producing answers. Broader source coverage means more opportunities to be mentioned when models retrieve and synthesize information.
