"Spikemail chose GreenArrow over a number of competitors to partner with for our email delivery platform. Their team is by far the best technical department to support the email campaigns for our clients in New Zealand to send to recipients worldwide. Their ability to interface with ISPs across the globe and provide outstanding customer service is second to none."
"Unlike typical mailing software systems, our customers benefit from high speed and high volume deliveries with the added benefits of automated and configurable Bounce Processing, delivery and speed throttling at the ISP level, private virtual mail servers for each of our clients, and more. Additionally, DRH's detailed deliverability analysis capabilities enable us to specifically identify problems with a client's list or mailing and even help identify which segments of a mailing list are responsible for generating sales, complaints, or no activity at all."
