    "Great experience so far"

    Posted 2025-11-28

    Pros: Super easy implementation, great communication from the Opensend team, team is always willing to hop on a call to get things figured out.

    Cons: I wish they had the ability to qualify the emails for us before passing them to our ESP, as I've done with other similar companies before.

    Overall: Overall I've been happy with Opensend. Set up was easy, their team did basically everything for us. Implementing with Klaviyo was a breeze and we started seeing additional revenue come in really quickly.

    Overall: The team at Opensend made it incredibly easy to get up and running, and start collecting high intent email addresses from engaged users, that can be remarketed to using our both owned and paid channels.

    "Leveraging partnerships for scalable growth and exceptional customer service "

    Posted 2025-01-10

    Pros: What I appreciated about working with Opensend is their comprehensive approach to explaining the platform and its functionality. They provided all the necessary details, allowing me to confidently introduce the brands I work with to this new platform. The level of customer service and their thorough responses to optimizations and questions were impressive.

    Cons: When implementing any new platform that identifies site visitors, it can initially seem concerning. However, having a comprehensive plan to nurture these contacts is crucial. We received excellent resources to support this process. While some best practices may not suit every brand and service, nothing stood out as problematic. Just ensure to monitor early on and adjust the strategy as needed.

    Overall: We noticed a YoY decline in new sign-ups, so we tested new email captures and optimizations. Seeking alternative solutions to attract more visitors and increase brand awareness, we turned to Opensend. This allowed us to drive new visitors to the site and generate additional revenue. Once new visitors are captured and added to your ESP, it's crucial to implement a strategy to nurture these audiences differently than usual across your Flows and Campaigns.

    Pros: Absolutely love Opensend - it has increased the retention revenue for our entire book of business and is extremely easy to integrate

    "Got a great ROI from anonymous visitors"

    Edited 2024-11-16

    Pros: Opensend is easy to set up and worked directly with Shopify + Klaviyo. The team is very responsive and also provided some great tips to get started. I like that this solution requires no active management once it is set up.

    Cons: I wish the platform had native A|B testing and that I had more controls over which emails were allowed (e.g. non-corporate only, certain domain names etc...)

    Overall: Overall, I would recommend Opensend to anyone looking to get a higher ROI out of their email program. It's easy to use, simple to setup and the team is very supportive.

    "Game changer "

    Posted 2024-11-13

    Pros: Engaging customers who are already interacting with our clients' brands but haven’t provided their email addresses is a game changer.

    Cons: I honestly can’t think of a single area where Opensend hasn’t exceeded our expectations.

    Overall: Opensend has been an invaluable addition to our marketing toolkit. Its user-friendly interface has enabled us to generate revenue beyond our expectations. I highly recommend it to anyone looking to elevate their email and SMS marketing efforts.

    "Best List Growth Tool"

    Posted 2024-11-11

    Pros: Opensend stands out for delivering higher-quality email leads to your ESP. Unlike some competitors, Opensend vets each email for recent activity and intent, only passing leads that meet best-practice standards, including time-on-site delay requirements. This ensures your deliverability remains unaffected, and these qualified leads are more likely to convert into sales. The ROI? Truly impressive.

    Cons: While slightly on the pricier side, Opensend consistently delivers a fantastic ROI of over 10x. I’ve implemented it across 8+ sites, and each one has seen exceptional returns.

    Overall: Opensend has been a game-changer, delivering immense value across email revenue, Meta and Google Ads retargeting, and driving exceptional email list growth. It not only boosts conversions from prospects but also supports long-term customer value (LTV). Additionally, it’s a fantastic tool for cleaning up inactive emails, ensuring your list stays healthy. The user interface is incredibly intuitive, making integration with ad channels seamless and efficient.

    "Growth Unlock"

    Posted 2024-11-08

    Pros: After evaluating all the key platforms in this space, I chose Opensend, and it has been highly successful for our lead generation and email marketing. Opensend allows us to engage with otherwise anonymous site visitors and focus on high-intent users by targeting based on time spent, pages viewed, and specific page activity. The integration with Klaviyo is seamless, and the platform is very user-friendly. Although we’re still in the early stages, OpenSend is already showing strong initial ROI.

    Cons: Opensend requires credit card billing rather than invoice billing, which my company would prefer.

    Overall: Opensend is a powerful growth tool for brands looking to improve customer acquisition. It’s easy to use, offers strong onboarding and support, and has a proactive team dedicated to our success. I highly recommend it for anyone looking to convert anonymous site visitors into customers.
