Email marketing leader announces new Link Monitoring in Email Guardian solution

BOSTON & SAN MATEO, Calif. — March 6, 2024 — Litmus, a leader in email marketing, announces the launch of Link Monitoring in Litmus Email Guardian, the only solution that proactively monitors emails for unexpected changes and now, broken links. As email volume rises, this new feature detects potential issues before they negatively impact subscriber experiences. With 86% of customers abandoning a trusted brand after just two poor experiences, broken links are more than just an inconvenience. Link Monitoring is essential for marketers to create consistent, high-quality email interactions that build trust, boost loyalty, and drive revenue.

Email Guardian’s Link Monitoring continually checks link functionality in monitored emails, proactively alerting marketers when broken or slow-loading links are detected. Marketers can view their link journey, including the time it takes any redirects to load, and preview the link destination page—all without leaving their email. Ultimately, Link Monitoring empowers marketers to protect their reputation before and after they hit send.

This new feature is the latest addition to Litmus’ Email Guardian monitoring solution, helping brands ensure successful engagement and positive subscriber experiences while reducing the chances of poor engagement and a drop in clickthrough rates, which can lead to lost subscribers and deliverability issues. Always-on email monitoring is essential for marketing success, as every error can frustrate audiences, causing them to unsubscribe and brands to lose revenue. With 25-35% of revenue on the line, brands cannot afford to neglect effective email monitoring.

“With email volume tripling over the past three years alone, manual link testing is an insurmountable task for marketers,” says Erik Nierenberg, CEO of Litmus. “Litmus Email Guardian’s Link Monitoring empowers marketers to send emails with confidence, safeguarding their brand’s reputation, orchestrating seamless customer journeys and maximizing email revenue. In today’s digital landscape, emails transcend mere messages; they’re a reflection of your brand identity and customer commitment. Maximizing the effectiveness of every send has become a necessity for any successful email marketing program.”

Only Litmus Email Guardian enables marketers to:

  • Automatically monitor links in enrolled emails 24/7 without any manual work.
  • Proactively receive alerts when broken or slow-loading links are detected.
  • Resolve critical issues pre-send, ensuring seamless subscriber experiences.
