API Performance
We claim under 300ms and deliver ~150ms on average. Here is the data to prove it.
Real-Time Monitoring Dashboard
We monitor API latency 24/7 with synthetic probes. This is an actual screenshot from our Grafana monitoring infrastructure -- not a mockup.
Where the Time Goes
A breakdown of the ~149ms average API response time. Most of the latency is network overhead (TLS + TCP), not processing.
MX record lookup for the recipient domain
Establishing a secure connection to the mail server
Network round-trip to the SMTP server
SMTP verification, disposable check, and scoring
How We Compare
Most email validation providers do not publish their API latency. Here is what they claim versus what we measure and prove.
| Provider | Claimed Latency | Evidence |
|---|---|---|
MailOdds You are here | 149ms measured avg | Live Grafana dashboard (shown above) |
| ZeroBounce | 3,000ms avg | Self-reported |
| Bouncer | <10,000ms | Self-reported |
| Emailable | 12ms | Self-reported, unverified |
| Clearout | 0.5ms | Self-reported, unverified |
| NeverBounce | Not published | No public data |
Competitor data is based on their publicly available documentation and marketing materials as of February 2026. Claims marked "unverified" could not be independently confirmed. We welcome any corrections.
Why Latency Matters for Email Validation
Real-Time Signup Forms
Validate emails inline as users type. Sub-300ms responses feel instant -- users never notice the check happening.
High-Volume Pipelines
Processing 10,000 emails at 149ms each completes in under 25 minutes sequentially, or seconds with bulk endpoints.
API Gateway Timeouts
Slow validation APIs risk triggering gateway timeouts. At 149ms average, MailOdds fits comfortably within any timeout budget.
