About Opensend

Opensend is a lead generation platform that enables e-commerce brands to identify anonymous website visitors and convert them into known, addressable customers. The platform uses proprietary identity technology to capture emails and other identifiers from high-intent visitors who do not complete a purchase, allowing businesses to grow their email lists and re-engage these shoppers through multi-channel marketing campaigns including email, SMS, and programmatic advertising. Opensend offers AI-powered persona targeting, which segments customers based on real behavioral data to create personalized marketing strategies. The platform integrates seamlessly with major marketing tools such as Klaviyo, Meta, Google, TikTok, and more. Opensend’s solutions include Connect (real-time visitor capture), Reconnect (cross-device identity resolution), Ignite (server-side conversion tracking for Shopify), and Personas (AI-driven customer segmentation). With a proprietary identity graph spanning over 180 million shoppers, Opensend provides a 73% match rate for US-based shoppers. The company emphasizes legal compliance with CAN-SPAM and CCPA, and serves over 1,000 brands. AiDOOS enhances deployment and adoption by offering custom integrations, expert onboarding, and ongoing optimization support, ensuring that businesses maximize their return on investment from Opensend.

"Effortless Implementation, Outstanding Customer Service"
I've had a wonderful experience with Opensend. Their customer service is excellent, with team members like Jeffrey and Sergio helping us get up and running efficiently. The onboarding process was smooth, and their team ensured everything was in place quickly, only delayed by our IT department's tasks. The seamless integration with Klaviyo improves the user experience, making it a valuable tool in our marketing arsenal. Moreover, Opensend's reconnect platform is highly effective, allowing us to identify and target anonymous website visitors, resulting in higher conversion rates. The ability to target previously unreachable users has significantly increased our revenue. Opensend's tools stand out above others like Wonderken and retention.com, proving to be more effective in our experience. I wish Opensend had a larger user database, as not everyone is currently included. While the platform already has broad reach, expanding to identify more users would be beneficial. I use Opensend to identify anonymous website traffic, boosting conversions and revenue. Their seamless onboarding and excellent customer service were crucial in setting up flows targeting users we couldn't otherwise reach.

"Transformation with Outstanding Onboarding Experience"
I absolutely love Opensend for the huge success we've had, especially in scaling our triggered flow revenue by nearly 100%. It has been a fantastic investment, delivering an impressive 29X ROAS. The platform excels at helping us reach potential customers with relevant, timely content, which is increasingly difficult with traditional campaigns. The onboarding process with Opensend was remarkably easy and fast; it was seamless thanks to the excellent onboarding team who were very helpful in setting up our flows. Setting up the Klaviyo integration was a breeze, taking only minutes, which was very convenient. I am completely satisfied with the service, as shown by my high likelihood of recommending Opensend, giving it a solid 10 out of 10. Nothing. I use Opensend to scale our triggered emails, effectively reaching and retargeting visitors, resulting in nearly 100% increase in triggered flow revenue with a 29X ROAS.

"Smooth Onboarding, Quick Support, Revenue Increase"
I like Opensend because it's very easy to get started, with a highly responsive onboarding team. They react quickly to any changes in our existing CRM stack, usually within twenty-four hours. This ensures I never worry about people getting incorrect messages. It integrates extremely well with Klaviyo, which adds significant value to our workflow. The initial setup was quite easy and very hands-off. We just connected our CRM accounts and were up and running. Nothing to report so far. I use Opensend to identify visitors that my usual tech stack cannot recognize, triggering more flow emails and boosting revenue.

"A straightforward and effective tool for engaging site visitors"
We can market to our site visitors in a meaningful and engaging way. Once we obtain an identity, we can send our welcome series and tell them more about our product. It's simple and easy to use, serving as a great funnel to capture visitors from our Google and Meta ads. It integrated seamlessly with Klaviyo, and the dashboard is user-friendly. We had a great onboarding team that made setup simple. They've been responsive whenever we have questions or need support. The CAC is a bit higher than some other channels, but some of that is on us to improve our welcome flows and create a better offer. We are using Opensend to generate sales and grow our mailing list. Opensend is ideal because it attaches names to visitors we would never have known otherwise. It's helping us improve conversion rates and make our ad spend more effective.

"Simple Setup with Great Support"
I really valued the customer support from Opensend. Setting it up without them would have been tough. The steps to install it on a platform without native integrations were a bit confusing, but they made it easy. The initial setup of Opensend was also easy. I wish the follow-up support were better. After capturing leads, I'm left wondering what to do next. It would be helpful to have a clearer guide on using Opensend's connect and reconnect features with other CRM platforms. I use Opensend to capture contacts for e-commerce sales, building a list of potential customers to convert into active buyers.

"Simplified Identity Resolution with Quick Setup"
I appreciate that Opensend provides a 'set and forget' experience, making it very convenient without constant monitoring. The entire suite is excellent and very simple to set up, making the initial installation pretty easy. I find maintaining separate flows somewhat annoying, but I suppose it's part of the deal. I use Opensend for identity resolution, which helps me identify unknown visitors.

"Excellent Support and Easy Implementation"
I really value the amazing support from Opensend. Their team was excellent during onboarding, quickly jumping in to help, checking our flows and connections, and offering guidance whenever we got stuck. The instructions were clear, making the initial setup easy for us. More transparency on how email addresses are captured and matched would be beneficial. Opensend obtains email addresses from site visitors, enabling us to market to those who don't convert right away.

"Easy List Growth and Powerful Features with Opensend"
I like how comprehensive the Opensend dashboard is; it looks very clean and is easy to navigate. I really value the white glove support because they handle all the setup and communicate frequently, offering insights and ensuring flows work properly. They are very proactive. I appreciate that we can track everything accurately on both Klaviyo and Opensend, and the numbers align. I also like that Opensend constantly releases new features, and it's very customizable, letting us choose how many people we want and set conditions, which is rare among identity resolution tools. That's quite good. The credit system is simple and clear, and you can select the engagement level. The dashboard makes it easy to monitor list performance without splitting every campaign or flow in Klaviyo, saving a lot of time. Initial setup was very easy, completed in a couple of hours with a lot of assistance from their team. We had to do very little. Improvements: I'd like more analytics features on the dashboard, such as lifecycle and churn risk. The revive program could identify more people, and it would be helpful if it were automated without manual list uploads. An integration for that would also be beneficial. I use Opensend to grow client lists and generate extra revenue. It helps reconnect with people who left, like purchasers, without relying on slow methods like direct mail. Opensend has enhanced client list growth, especially when facing deliverability challenges.

"Great Integration with Accurate User Profiles"
I really enjoy the integration with Opensend. It's very easy and quick to deploy in just minutes. We use it with Klaviyo to reengage users through email, and that process is also straightforward. The users identified by Opensend are active, and their data is very accurate. The precise data helps us reach the right people even if they didn't subscribe with us directly. Improvement areas: their internal analytics could provide more clarity on what's working. Also, handling suppressions for users who don't want our emails could be clearer. We've created our own internal processes, but it would've been helpful to have best practices to maximize Opensend without hurting deliverability. Opensend identifies traffic that doesn't engage with our brand and lets us reengage them via email, even after they leave the site.

"Top Choice for Identifying Anonymous Site Visitors and Growing Email Lists"
I've implemented Opensend at two different companies and compared it to a couple of competitors; it consistently comes out as the top solution for identifying unknown website visitors and extending cookie durations for abandoned cart flows. All tools struggle with this, but I'd like more precise attribution metrics in the Opensend dashboard. The revenue reports seem inflated, but still, Opensend's Connect and Reconnect features clearly bring in more subscribers and revenue than we'd have otherwise. It grows our email list, allowing us to reach more visitors than those who initially subscribe. It captures more email subscribers in abandonment flows than Shopify or Klaviyo can with their cookie expiration. It generates more revenue from new customers who are hesitating.
