Knock Email API Benchmarks

What is Knock Email API Benchmarks?

Knock Email API Benchmarks is a comprehensive, data-driven resource designed to provide real-time insights into the performance, reliability, and uptime of various email service providers (ESPs). Leveraging proprietary data collected from billions of messages processed through the Knock notification infrastructure, this tool offers an unparalleled view into how different email APIs perform under real-world conditions. It goes beyond theoretical capabilities to show actual, day-to-day operational metrics, helping developers and businesses make informed decisions about their email delivery infrastructure.

The platform allows users to sort and filter providers based on critical metrics such as response time, error rates, delivery speed, and channel growth. This granular level of detail empowers users to identify the best-performing providers for their specific needs, whether they prioritize speed, low error rates, or consistent uptime. By analyzing data over a significant trailing 90-day window, Knock ensures that the benchmarks reflect the true variability and performance of production systems, rather than isolated, short-term load tests. This approach provides a more accurate and trustworthy assessment of each provider's capabilities.

Getting started with Knock Email API Benchmarks is straightforward:

1. Explore the Dashboard: Visit the Knock Email API Benchmarks page to view the main performance table.
2. Analyze Provider Metrics: Use the sort and filter options to examine key metrics like median response time, error rate, and growth rank for each email provider.
3. Compare Providers: Utilize the "Compare providers" feature to select two specific ESPs and see a side-by-side analysis of their performance and other relevant data.
4. Deep Dive into Specific Providers: Click on individual provider names to access detailed benchmark reports, feature comparisons, pricing information, and integrated status page updates.
5. Understand the Methodology: Review the "Our methodology" section to understand how the data is collected and the metrics are calculated, ensuring you can interpret the results accurately.
6. Request Missing Providers: If you don't see a provider you're interested in, use the "Request a provider" option to submit your suggestion to the Knock team.

This tool is designed for quick insights and in-depth analysis, allowing you to make data-backed decisions about your email sending strategy.

Use Cases

• Choosing a New Email Provider: Businesses looking to switch or select a new email service provider can use these benchmarks to compare the performance, reliability, and cost-effectiveness of leading options before making a commitment.
• Optimizing Existing Infrastructure: Development teams can identify underperforming email providers in their current setup and explore alternatives that offer better response times, lower error rates, or improved deliverability.
• Technical Due Diligence: For companies evaluating third-party integrations or services that rely on email delivery, these benchmarks provide crucial data points for assessing the technical robustness and reliability of the underlying email infrastructure.
• Performance Monitoring and Alerting: By understanding the typical performance ranges of different providers, teams can set more informed internal benchmarks and alerts for their own email delivery systems.
• Cost-Benefit Analysis: While not directly pricing benchmarks, the performance data can be correlated with provider costs to help teams find the optimal balance between speed, reliability, and budget.

FAQ

Q1: How often is the data updated? A1: The benchmarks are updated daily, reflecting a trailing 90-day window to ensure the data represents current performance and accounts for system variability.

Q2: What does "Growth" refer to in the benchmarks? A2: "Growth" rank reflects how many new channels (connections to a provider API) were created for each provider within Knock during the 90-day window. It indicates the increasing adoption and usage of a provider by Knock users.

Q3: How is response time measured? A3: Response time is measured from when Knock sends an API request to the provider until a 200 status code (indicating acceptance) is received. This measurement includes network latency and connection pooling time, and importantly, includes any duration added by Knock's automatic retry logic for retryable errors.

Q4: What if my preferred email provider is not listed? A4: Knock encourages users to request providers they would like to see benchmarked. You can submit your request through the "Request a provider" link on the page, and Knock will consider adding it to future updates.

Q5: How does Knock ensure the accuracy of these benchmarks? A5: Knock uses a transparent methodology based on billions of real-world messages processed through its platform. The use of a 90-day window, precise quantile calculations, and consistent measurement across all providers aims to provide an accurate and reliable representation of email API performance.
