Solution Used:
Netcore Email


Important transactional emails – like forgotten password resets, payment alerts and reminders – were delayed or not delivered. They tried to fix it several times in different ways because it was causing customer complaints, but nothing worked.

Netcore’s Strategy

First things first – delivery speed. Customers expect critical transactional emails in less than 5 seconds. For this reason:

  • we warmed new IP’s, over a 2-month period. In order to warm the site effectively, we segmented the email content by its type.
  • Each type of email was evaluated and prioritized, based on the email delivery speed that was required.
  • Then, we built the infrastructure based on our findings and our clients priorities.
  • Use Unique Segmentation to Warm IPs and Deliver Critical Emails
  • We applied best practices across the board. For example, we helped our client use transactional emails safely for cross-sell and up-sell purposes.
