Dynamics 365 Customer Insights - Journeys

Hello MG-01111147-0,

You're asking a very important question about the hard bounce limit (8%) in Dynamics 365 Customer Insights - Journeys (CIJ). This limit is crucial for maintaining your sending reputation and ensuring email deliverability.

Here's a breakdown of what the 8% hard bounce limit means and how it's applied:

Understanding Hard Bounces:

Hard Bounce Definition: A hard bounce indicates a permanent delivery failure. This typically occurs due to:
- Invalid email addresses.
- Non-existent domains.
- Blocked email servers.

Impact on Sender Reputation: A high hard bounce rate signals to email providers that your sending practices might be poor, leading to:
- Increased spam filtering.
- Lower inbox placement.
- Potential IP address or domain blocking.

The 8% Hard Bounce Limit in CIJ:

Purpose: Microsoft enforces the 8% hard bounce limit to protect its email infrastructure and ensure good deliverability for all its customers.

Application:
- CIJ monitors your hard bounce rate across your email sending activities.
- If your hard bounce rate exceeds 8%, your email sending capabilities might be suspended.
- The 8% is a cumulative number.

What it contains:
- The 8% limit applies to all emails sent through CIJ within a defined period.
- It's not calculated on a per-journey or per-email basis, but rather across your overall email sending volume.
- It is a rolliong number. Meaning that old hard bounces will still count towards the 8% until they are old enough to be out of the measured time frame.

Why it is important:
- This is to protect the sender reputation of the Dynamics 365 Customer Insights - Journeys service.
- If a tenant is sending emails to many invalid email addresses, it will harm the other tenants that are using the same service.

Key Considerations:

Data Hygiene:
- Regularly clean your email lists to remove invalid or outdated addresses.
- Implement double opt-in (DOI) to ensure that you're only sending emails to valid and interested recipients.

Monitoring:
- Monitor your hard bounce rate closely using CIJ's email insights.
- Take immediate action if you notice a spike in hard bounces.

List Segmentation:
- Segment your email lists based on engagement and recency.
- Focus on sending emails to your most engaged subscribers.

Feedback Loops:
- Set up feedback loops with email providers to receive notifications about hard bounces.

In summary, the 8% hard bounce limit in CIJ applies to your overall email sending activities within the service. It's crucial to maintain good data hygiene and monitor your bounce rates to avoid suspension and ensure optimal email deliverability.
