    This one is up to you and we’ll tell it to you straight: sending wanted, expected, and relevant email is essential to your Inbox success.

Achieve Volume & Speed

Have a big list and an important deadline? Need high-performance? Don’t be held back by slow software. GreenArrow users boast sending 10M+ emails an hour with up to 8,000 concurrent connections. GreenArrow’s Engine will ensure your time-sensitive messages are delivered on time.


Intuitive Interface

We’ve built an intuitive, easy-to-use web interface for technical and non-technical teams, alike. For example, easily assign different delivery attributes to various classes of email.


Encrypted Delivery

Prevent passive intermediaries from reading, intercepting or modifying your email. GreenArrow provides opportunistic TLS encryption for SMTP deliveries. If the remote server does not support encryption, GreenArrow’s Engine will deliver without encryption.


Dynamic DeliveryTM

Automatically adjusts your delivery settings based on how the ISPs are responding to you.

When the ISPs push back on your email delivery, GreenArrow’s Dynamic Delivery will automatically throttle down your sending rate, which, by being polite, can help improve your overall delivery.


Advanced Reporting

Get more insight into your campaigns and deliverability, including the ability to drill down to ISP deferral and failure messages.

Discover 51 data points, including: detailed bounce codes, spam complaint rates by domain, clicks/opens and more. Pair these reports with Inbox Monitor analytics to identify weaknesses or opportunities for improvement.
