Booking email that leaves from Custom SMTP.
Custom SMTP means sending through a mail server you control, so booking email leaves from your own domain and sending reputation. Confirmations, reschedules and reminders go out as ordinary email, with a calendar invitation attached and a link to manage the booking.
What is switched on depends on your plan and industry pack. Ask us to confirm before you build a process on it.

What Custom SMTP brings to your booking workflow
A written record of the booking
The confirmation is the thing people search their inbox for the night before.
The invitation comes with it
A calendar invitation means the appointment ends up in the guest's own calendar, not only in yours.
Your domain, your reputation
Sending through Custom SMTP keeps booking email aligned with the address your customers already trust.
How it works
Three steps to a connection you can trust. Follow the screens in your own account for the exact wording.
- 1
Point at the right sender
Set up the Custom SMTP account or server that booking email should use.
- 2
Check what each message says
Review the confirmation, the reminder and the reschedule note before anyone else does.
- 3
Book a test and read the inbox
Confirm receipt, the invitation and the manage-booking link from the recipient's side.

Custom SMTP questions
Is this a Custom SMTP mailbox integration?
No. This is about sending booking notifications. Your mailbox is not read, synced or filed by udaybooking.
Will reminders always reach the inbox?
No one can promise that. Use a sender aligned to your domain, keep the content plain, and test receipt before you rely on it.
Is Custom SMTP available on my plan?
Custom SMTP is in udaybooking's connector catalogue, and what is switched on depends on your plan and the industry pack you run. Ask us to confirm it for your account before you build a process around it.
