Success stories from our customers

“We had a ton of traffic hitting the site, but we were struggling to engage with most of these visitors. We partnered with Opensend and Flowium to test out Opensend's Connect service, running a scientific hold-out group experiment - the test group that we engaged with our email flows dramatically outperformed the holdout group, giving us a strong ROI within weeks.”

“We ran a split-test, with 30% going to a control group. We tagged contacts in Klaviyo based on whether they went through Opensend. We pulled that data from Klaviyo to calculate results. There was no reliance on Klaviyo cookie tracking. It was pure lift.”

“We compared Opensend's Connect tool with Retention's Grow and found a clear difference. Opensend's contacts consistently converted at a higher rate, which made a real impact on performance. The dashboard also stood out—it's cleaner, more intuitive, and easier for our team to work with day-to-day. While the cost per contact is slightly higher, the overall value and ease of use made Opensend the right choice for us.”

“Opensend has completely transformed how we engage with our Meta ad audiences. By seamlessly scraping and segmenting contact data into our CRM, they've enabled highly targeted email and SMS campaigns driving over $100K in additional revenue in just the first 3 months. It's been a game changer for our customer acquisition and retention strategies.”

“Opensend has become a quiet growth engine for Gardencup. By identifying more than 370K previously anonymous shoppers and keeping them engaged with 67% open rates, we've turned passive interest into real revenue—$2.6M+ in placed orders so far. In the last 30 days alone, Reconnect added ~$19K in incremental sales with virtually no lift from our team. It's the easiest ROI decision we've made this year.”

“Using Revive, we were able to bring back thousands of previously inactive customers that we had no way to reach before. The engagement was impressive, and the return made it well worth the effort. The whole process was fast, easy, and effective”

“I love that our client list growth has increased more than 6% year-over-year since starting with Opensend. It's rare to see a tool deliver results this consistently.”

“By combining Nostra with Opensend, we don't just extend cookies—we extend visibility. That means more known users, longer attribution windows, and more revenue captured from traffic others miss—something no standalone platform can replicate.”

“Opensend turned anonymous traffic into known customers. We could finally retarget and personalize for shoppers who would've otherwise disappeared.”

“Opensend has been a true unlock for UTV Source. For years, we'd worked with various identity-resolution providers and never saw the kind of measurable lift we're seeing now. Opensend consistently recovers sales that used to slip through the cracks, and the customers it identifies convert at nearly double the typical order value. It's rare to find a partner that moves the needle this clearly, but Opensend has proven itself an essential part of our profitability stack.”
