Everything you need to know about SendX and email marketing
Mailgun is a great starting point for developers who need quick, reliable email delivery. But when your sending volume scales, and inbox placement becomes mission-critical, SendPost is the platform built to deliver.
We specialize in the high-speed, reliable delivery of transactional emails. Our infrastructure is built on managed IP pools with proactive monitoring to protect sender reputation. Unlike bulk marketing platforms, our systems are optimized to ensure your critical emails—like password resets, invoices, and alerts—reach the inbox instantly.
SendPost is significantly more cost-effective for transactional and high-volume email. Our pay-as-you-go pricing is tied directly to your usage, not your subscriber count. This means you don't overpay for storing contacts and only get charged for the emails you actually send, making it a more economical and scalable solution for applications.
Migration is incredibly simple. For most applications, switching to SendPost is as easy as updating your SMTP credentials or changing an API endpoint in your code. Our clear documentation and dedicated technical support are available to ensure your transition is smooth, fast, and without any disruption to your service.
While our core offering is a robust API and SMTP service, SendPost provides a complete email delivery solution. All accounts include access to a powerful dashboard with deep, real-time analytics on deliverability, engagement, and bounces. This gives your team full visibility and control over your entire email program, not just a black box API.
