MailSlurp is a powerful messaging API platform built for developers, QA teams, and site reliability experts. Use MailSlurp to execute email infrastructure load testing with Grafana K6.
Send email in K6
Easily send mail at scale with simple HTTP requests:
Read email in K6
Receive messages and attachments in your scripts using versatile wait methods that hold open a test until matching conditions are met:
Create dummy inboxes
Generate unlimited real email accounts on demand via HTTP and the use the email address for user flows:
Phone numbers and SMS
It's not just email - MailSlurp also provides real phone numbers for stress testing inbound and outbound SMS.
Test SMTP servers
Despite using Javascript K6s is not node compatible meaning testing SMTP servers can be tricky. Luckily, MailSlurp has an extensive HTTP/S API for performing all SMTP server actions from within K6!
Reliable and Scalable Email Performance Testing
Ensuring your email infrastructure performs under real-world conditions is critical for businesses dependent on transactional and marketing email communications. MailSlurp's powerful integration with k6 offers comprehensive email infrastructure load testing to keep your service running smoothly under peak loads.
Why Email Load Testing Matters
Email sending and receiving is a fundamental aspect of modern business operations, yet it often remains under-tested until issues arise. Performance bottlenecks, delays in transactional email deliveries, or complete outages can lead to frustrated customers, lost revenue, and reputational damage. Proactively load testing your email infrastructure can prevent these scenarios, helping you understand email throughput, delivery latencies, inbox ingestion rates, and server reliability.
MailSlurp combined with k6 helps you simulate real-world traffic, checking SMTP server reliability, measuring latency, and assessing queue performance to maintain robust email deliverability.
Leveraging k6 for Email Performance
k6 is a developer-friendly, open-source load testing tool ideal for rigorous testing of email infrastructures. Its flexibility allows testers and DevOps engineers to simulate complex email sending and receiving scenarios through straightforward scripts. MailSlurp simplifies this integration, enabling automated checks for SMTP performance, inbox monitoring, and transactional email flow.
Using k6, your teams can quickly build detailed load tests that verify email message throughput, assess inbox delivery speeds, and identify issues like email queue backlogs. MailSlurp enhances these tests by allowing real email sending and receiving within your scenarios, enabling precise measurement of deliverability metrics.
Enhance Email Reliability and Infrastructure
Reliable email delivery isn't just about sending messages; it's also about ensuring those messages consistently arrive promptly and securely. MailSlurp and k6 provide tests that check email authentication protocols like DKIM, DMARC, and SPF under load. These tests ensure your messages reliably reach their destination inboxes without being marked as spam or rejected.
Additionally, using load tests to monitor IP reputation, bounce rates, and email latency allows you to proactively resolve issues before they impact users. Regular testing ensures your email infrastructure scales effortlessly, handling spikes in transactional email volume without disruption.
Seamless CI/CD and DevOps Integration
Modern development teams rely on continuous integration and deployment pipelines to maintain fast release cycles. MailSlurp integrates effortlessly with platforms like GitHub Actions, GitLab CI, Jenkins, and Azure DevOps, allowing automated load tests for email performance.
Incorporating email infrastructure testing into your CI/CD pipeline provides real-time feedback on email reliability, alerting your teams to regressions or performance degradations immediately. This integration significantly enhances your DevOps processes, minimizing downtime and maintaining high email deliverability standards.
Solve Email Performance Problems Before They Start
Many companies experience email deliverability problems only when customers complain. MailSlurp's proactive load testing identifies and resolves potential performance bottlenecks, latency issues, and reliability concerns early in the development lifecycle. By simulating real-world scenarios like high-volume email sending or transaction-heavy email workflows, MailSlurp enables you to troubleshoot and optimize your infrastructure before performance issues escalate.
