### Achieve Better Deliverability with AhaSend

AhaSend is optimized for transactional emails, offering faster and more reliable delivery than Mailjet. While Mailjet handles both marketing and transactional email from a single platform, AhaSend is purpose-built exclusively for fast, reliable email delivery — with infrastructure and tooling designed specifically around transactional performance.

- Proven experience delivering millions of emails monthly
- Enhanced delivery speeds tailored for transactional emails
- Dedicated to fast and reliable transactional email delivery

### Gain Insight with Advanced Reporting

Mailjet tracks opens, clicks, and bounces — but stops there. AhaSend goes deeper, exposing raw SMTP error codes, full bounce categorization, and DSN reports so you can actually diagnose and fix delivery issues, not just observe them.

- Detailed bounce reasons for improved performance
- DSN reports for deep deliverability analysis — unavailable on Mailjet
- Actionable insights to enhance your email strategy

### Monitor Email Events in Real-Time with Webhooks

AhaSend offers comprehensive webhook support for real-time email event notifications, keeping you informed on every step of your email’s journey. Our webhooks ensure you can easily track and respond to key events like delivery, bounces, and opens.

- Instant notifications for email delivery events
- Track events such as queued, delivered, bounced, and more
- Easily integrate webhooks into your applications

### Integrate Incoming Emails Seamlessly

AhaSend's Email Routing feature simplifies the process of directing incoming emails to your applications. Mailjet does not offer inbound email routing at all. With AhaSend, you can parse and forward messages based on custom rules, enabling smoother app integration for order confirmations, and reply-to flows.

- Automatically parse and direct incoming emails
- Integrate emails directly into your application workflows
- Separate the latest reply from the rest of the email content for precise handling

### Protect Your Domain’s Reputation

AhaSend helps you maintain a strong sending reputation through automated DNS configuration and continuous monitoring. Our tools are specifically designed to prevent common errors that could harm deliverability, ensuring your domain is optimized for successful email campaigns.

- Automated DNS configuration for quick, accurate setup
- Enforce best practices for DNS setup to boost deliverability
- Continuous monitoring of domain and DNS health status

### Protect Your Email and Application with Advanced Security

AhaSend prioritizes data security with customizable retention policies and proactive measures to block risky domains. Mailjet offers no reputation protection, no S3 archiving, and no configurable data retention. AhaSend's Reputation Shield blocks temp-mail addresses, typo-squatted domains, and toxic recipients before they damage your sender score.

- Set data retention periods to match your compliance needs
- Block emails to temporary and suspicious domains automatically
- Prevent typo-squatting attacks by filtering domains with typos
