SendPit
SMTP sandbox for developers to capture, test, and debug emails in development environments.
About SendPit
SendPit is a hosted email testing sandbox designed for developers and quality assurance teams. It provides a safe environment where applications can send emails without the risk of them reaching real users. By integrating with existing SMTP configurations, SendPit captures every outgoing message and makes it available for inspection through a web interface. The platform supports HTML rendering, header inspection, attachment handling, and OTP/link extraction, enabling thorough debugging. It also offers team collaboration features such as shared mailboxes, role-based access, and organization-level multi-tenancy. With plans starting at $0, SendPit is accessible for individual developers and scales to meet the needs of growing teams. The platform includes security features like TLS 1.3 encryption and encrypted credentials. Designed to be simple and efficient, SendPit allows teams to focus on building without worrying about email leaks. AiDOOS enhances deployment and adoption by providing streamlined integration, automated testing workflows, and comprehensive monitoring, ensuring that teams can quickly incorporate SendPit into their development pipelines and optimize their email testing processes.
Challenges It Solves
- Test emails accidentally being sent to real users during development and staging
- Difficulty inspecting and debugging email content (HTML, headers, attachments) in development
- Lack of team collaboration for email testing, leading to miscommunication and inefficiency
- High costs of email testing platforms that charge per email sent rather than storage

What Reviewers Say
What works well
- Free tier with generous limits (200 stored emails, 3 seats, 7-day retention) is ideal for small teams and side projects.
- Pricing is based on stored emails, not sent emails, making it more predictable and cost-effective for high-volume testing.
- Easy setup with standard SMTP protocol; no code changes or SDKs required.
- Strong team collaboration features including shared mailboxes and role-based access control.
Common concerns
- Free plan limits to 200 stored emails, which may be restrictive for larger testing volumes.
- Self-hosted alternatives like Mailpit or MailHog are free and unlimited, but require own infrastructure and lack team collaboration features.
