Email deliverability measures the percentage of emails that successfully reach recipients' inboxes. Key health metrics include bounce rates, spam complaint rates, and overall delivery rate.
Enter your email sending metrics from your email service provider (ESP) dashboard to calculate deliverability health.

Email deliverability is the foundation of email marketing success. Even the best-written email campaign delivers zero ROI if messages never reach the inbox. In 2024, Google and Yahoo implemented strict sender requirements that made deliverability hygiene more critical than ever for bulk senders.
Example 1: Healthy List
Sent: 20,000 | Hard Bounces: 40 (0.2%) | Spam: 10 (0.05%)
Delivery Rate: 99.8% | Sender Score: 92/100 — Excellent
Example 2: At-Risk List
Sent: 15,000 | Hard Bounces: 225 (1.5%) | Spam: 30 (0.2%) | Soft Bounces: 300 (2%)
Delivery Rate: 96.5% | Sender Score: 45/100 — Needs Immediate Attention
Key deliverability improvements: implement SPF, DKIM, and DMARC authentication, regularly clean your list by suppressing hard bounces immediately, use a double opt-in process for new subscribers, warm up new sending domains gradually, monitor your sender reputation via Google Postmaster Tools and Validity/Return Path, and never purchase email lists.
What is a good email deliverability rate?
A delivery rate above 98% is considered good. 99%+ is excellent. Anything below 95% indicates serious list hygiene or reputation problems that need immediate attention. Note that delivery rate measures reaching the mail server, while inbox placement rate (harder to measure) measures reaching the actual inbox vs. spam folder.
What is the new 2024 Google/Yahoo spam requirement?
In February 2024, Google and Yahoo began enforcing: (1) email authentication (SPF, DKIM, DMARC required for bulk senders), (2) one-click unsubscribe within 2 days, and (3) spam complaint rate must stay below 0.1%. Senders exceeding 0.3% complaint rate face severe inbox placement issues.
How do I reduce hard bounce rates?
Reduce hard bounces by: implementing real-time email verification at sign-up, using double opt-in to ensure addresses are valid, immediately suppressing hard bounces from all future sends, quarterly list hygiene using email validation services (NeverBounce, ZeroBounce, etc.), and removing subscribers inactive for 12+ months.
