  • ISP remediation and relationship management
  • Blacklist monitoring, including real-time alerts
  • Delivery and inbox monitoring
  • Feedback loop management

Services and features also include:

Message Throttling

Our highly configurable message throttling changes the sending speed to various ISPs, depending on how they are receiving your email campaigns.

Adapting to ISP Mail Server Response Codes

We dynamically manage your email campaigns by reading, interpreting, and changing sending patterns based on ISP response codes. This allows for maximum throughput of your mail, with optimum timing.

IP Sending Failover for Continued High Throughput

If one of your sending IP addresses gets clogged and delayed with an Error 4.xx SMTP response code, our software intelligence fails over to the next available IP address on the server, allowing sending to continue without delays.

Industry Whitelisting

To help your mail get through as cleanly and efficiently as possible, we maintain whitelists and complaint loops with all major ISPs. Equally important, we manage all complaints and unsubscribes for you automatically, in real time, so you don’t have to worry about people not getting unsubscribed instantly in real-time.

A Highly Responsive Email Delivery Team

We’re here to work with you individually to ensure your specific mailing needs and sending goals are being met. Our experts have helped clients send billions of emails for over 15 years. If we can’t get it delivered for you, nobody can.
