What our customers are saying
"Opensend has done wonders for our business - in our first 90 days we generated almost $70K in revenue by following up with visitors to our site with whom we previously could not engage. The installation was done in minutes, and the data quality is great; deliverability, open and click rates have all exceeded my expectations."

"By capturing a larger number of emails daily, we have reduced our reliance on costly programmatic retargeting campaigns and seen a noticeable improvement in our conversion rates. We see this as insurance for our advertising efforts, a no-brainer."

"Opensend is the perfect tool for e-commerce owners seeking to grow their email list profitability. Its simple installation and automatic email capture capabilities make it a must-have tool."
Oliver Walsh

"We tried other services like Open Send but they didn't work for our clients. We have multiple clients using the software and one of them is getting over 150 new leads a day and a 20x return on their investment from the cost of Open Send. A bonus for us is that the revenue is the same revenue that Klaviyo is tracking with Shopify data, so it's not making up random revenue attribution (that's out of the ordinary)."
