Disconnected systems send the wrong message to the wrong stage: a promo to a customer in a support escalation, or a cold pitch to a paying account.
The metrics that matter#
- Authentication pass rate: share of mail passing SPF, DKIM, and DMARC alignment. Healthy: 99% or higher.
- Spam complaint rate: Gmail enforces at 0.3%; stay under 0.1%.
- Hard bounce rate: under 2%; above 5% triggers platform reviews.
- Inbox placement: above 90% across major providers via seed tests.
- Engagement: click and reply rates by segment; opens are unreliable after Mail Privacy Protection.
Where to read them#
- Google Postmaster Tools for Gmail domain reputation, spam rate, and authentication.
- Microsoft SNDS and JMRP for Outlook.com IP reputation and complaints.
- Your ESP's delivery and bounce reports.
- DMARC aggregate reports for authentication by source.
Improving the numbers#
- Decide the system of record for each field.
- Sync bi-directionally only for fields that both sides change; otherwise one-way.
- Push email engagement (replies, meetings booked) into the CRM timeline.
- Suppress marketing to contacts in active sales conversations.
Frequently asked questions#
Which CRM integrates best with email automation?
Depends on your stack. HubSpot bundles both; Salesforce and GoHighLevel rely on connectors. The key is a single contact identifier.
