Send a Bulk Email to Multiple Recipients through Ripple
Ripple allows users to send emails in bulk to participants. This feature is useful for sending reminders, announcements, holiday greetings, and other important communications related to the study. Bulk emails can be created from scratch or by using an existing email template.

LIMITATION NOTE:
Ripple is designed to limit outgoing bulk emails to 20 recipients per batch, even when using the “Select All Potential” or “Select All Enrolled” participant options. This limit is in place to help manage server load and ensure compliance with email service provider standards that protect deliverability and reduce the risk of emails being flagged as spam.

Understanding Recipient Privacy in Bulk Emails
When sending a bulk email through Ripple, participant privacy is maintained at all times. Each recipient will only see their own name and email address in the message they receive.
What Recipients See:
-
Only their own name (as pulled from the participant profile)
-
Only their own email address
-
No information about other recipients included in the bulk email
This ensures that participant contact information remains confidential and compliant with privacy best practices. Bulk emails are delivered as individual messages, not as a visible group or distribution list.
✅ Best Practice: Always preview your email before sending to ensure merge tags and formatting display as intended.
