Client purchased 129M contact list for $15K. ESP showed almost no engagement. List looked dead.
19.6 million contacts with real engagement signals. That $15K "garbage" list is now worth $70K+ in campaign revenue.
"We thought our list was dead. VIP13 found 3x more engaged contacts than our ESP showed. Campaign performance doubled."
"The ROI is insane. We ran a broker list through VIP13, filtered to engaged only, and hit 4x our normal response rate."
"Finally, visibility beyond our own platform. We can actually see who's engaged across the ecosystem, not just our sends."

We aggregate engagement signals across the email ecosystem — billions of opens and clicks from multiple sources over 6+ years. Your ESP only sees engagement on emails sent through their platform.
We match contacts against 55 billion verified engagement events. If we say someone is engaged, they've opened or clicked an email within your specified timeframe. No guessing.
Hot = engaged in last 30 days. Warm = 31-90 days. Cold = 90+ days. You control the thresholds. We recommend Hot+Warm for best deliverability.
