Scheduled Email Sending

Last updated: April 7, 2026

Schedule your recruitment emails to be sent in the future. If you have participants in other time zones, or frequently prepare studies at off hours, scheduled email sending makes it easier to put your recruitment on autopilot.

This feature enables you to schedule bulk emails in advance to be sent out at specific times, and reschedule, pause, or cancel scheduled emails before the scheduled send time if needed. You can schedule emails for later when you are composing an email to be sent.


Schedule emails

  1. Select participants to include and select the Compose email button to select which email to send or create custom email.

  2. Edit the email subject and body to include all relevant information, links, and personalization tokens.

  3. Select Schedule to continue.

  4. Schedule when your email will be sent to participants.

    • Send now - Send messages immediately

    • Schedule later - Schedule for a specific date and time in the future

    • Autosend by frequency - Automatically send emails in batches at a set interval until your study's target is met

    • Autosend by date range - Automatically send emails evenly distributed between a start and end date until your study's target is met
