Email Deliverability with Humanic

Humanic uses Resend which is a modern email API designed for developers, focusing on simplicity, reliability, and strong deliverability for transactional and marketing emails.

Resend, Amazon SES, and Mailgun all offer strong deliverability rates, but there are differences in performance and features:

• Resend consistently reports near 100% uptime and high inbox placement rates due to its multi-region routing, built-in authentication (DKIM, SPF), and 24/7 monitoring. It is designed for developers and prioritizes transactional email reliability, with real-time insights and automated failover for maximum delivery consistency.​

• Amazon SES has a 2025 average inbox placement rate of about 85.66%, with roughly 11.31% of emails landing in spam and 2.89% not reaching recipients. SES benefits from Amazon's global infrastructure and is known for reliability, especially for bulk and transactional emails, but deliverability can vary by industry and sender reputation.​

• Mailgun has an average inbox placement rate of 81.81%, with about 14.28% of emails sent to spam and 3.30% lost. Mailgun’s deliverability is strong for most use cases, but performance can be lower for sensitive industries like finance or dating.​

In summary, Resend and Amazon SES tend to outperform Mailgun in deliverability, with Resend offering modern tools for monitoring and optimization, while Amazon SES leverages AWS’s robust infrastructure. Mailgun remains a solid choice but generally has slightly lower inbox placement rates
