Full Customization for Scheduler Notification Messages

Nylas Scheduler automatically sends confirmation emails to all attendees of a booked event if the Notifications are enabled. 

Currently, there’s no way to customize sender details, edit the content of those emails, or choose which attendees receive notifications from the Scheduler configuration. Also, the emails for the invitations sent by Scheduler will always come from:

Scheduling Assistant <no-reply@notify.nyl.as>

If you need more flexibility, such as sending notifications only to specific attendees, customizing the sender's address, or controlling the email content and branding, you can implement the following workaround:

Use Custom Notifications

You can disable Scheduler’s built-in confirmation emails and replace them with fully customized messages sent from your own domain. Here’s how:

Step 1: Disable Nylas Emails

In your Scheduler configuration, set disable_emails to true.

{
  "scheduler": {
    "disable_emails": true
  }
}

This prevents Nylas from sending confirmation emails to attendees.

Step 2: Send Custom Emails via Webhooks

Once Scheduler is configured, you can use webhooks to trigger custom email workflows.

1. Enable webhooks for event.created or booking.created (depending on your use case).

2. When a new booking is made, your webhook will receive the event payload.

3. Use this data to send tailored emails from your own service or via a third-party provider (e.g., SendGrid, Postmark, AWS SES...).

This gives you full control over:

• Recipients – Send only to the attendees you choose.

• Sender details – Use your own domain and display name.

• Branding and content – Personalize subject lines, body text, or templates.

Example Workflow

• Scheduler booking is completed.

• Webhook fires with booking details.

• Your app parses attendees and business rules (e.g., only send to host + main attendee).

• A custom email is sent from your preferred email service.
