Your booking emails should come from you, not us.
Right now, when someone books a meeting with you, the confirmation email lands in their inbox from a scheduling tool's domain. That's not your brand. With schedule.so's Custom SMTP, every email — confirmation, reminder, follow-up, cancellation — goes out from your email address. Your clients see your name. Always.
Every confirmation email is a brand touchpoint. Make it count.
Think about the last booking confirmation you received. You saw the sender's name. You saw their email domain. That's the same experience your clients have — except right now, they're seeing someone else's brand instead of yours.
For a coach charging premium rates. For an agency sending proposals. For a clinic building patient trust. The email domain matters.
