Back-Of-The-Box Details

The InboxReady platform is designed to equip users with the data they need to identify and correct email deliverability issues through capabilities such as seed testing, email verification and analytics. Additional features and capabilities include:

  • Inbox Placement Testing that allows marketers to see if an email will land in the inbox or in a tab before they send;
  • Email Preview, which enables marketers to test their email across various devices and clients to ensure their email is correct;
  • Email Verification, designed to clean up existing contact lists and can be integrated into website forms or an app sign-up process to verify new users as well as assign risk factors to unengaged emails;
  • Blocklist Monitoring, which tracks IPs across a curated list of blocklist providers to spot and address problems in real-time; and
  • Spam Trap Monitoring that aims to help users understand the quality of their email lists to protect their reputation and profits.

Who It’s For

The solution is for enterprise marketers looking to reach their audience with high-quality, deliverable emails, improve the customer experience and drive revenue.
