Why Brands Are Moving Away from Opensend
All of these third-party visitor ID vendors are under the delusion that their data is 90% accurate when it’s really 70-95% wrong.
Here’s why it’s time to switch from Opensend:
Their Data Quality Is Poor
While Opensend claims to have a high accuracy rate, we’ve done tests showing 70-95% wrong!
Their Data is Limited
While Opensend provides email addresses and basic identifiers, it does not offer more detailed information about visitors.
They Hurt Email Deliverability
Other visitor ID providers focus on volume of emails vs. quality of emails, resulting in deliverability issues.
Limited Feature Set
The Opensend platform lacks features like customer journey tracking and advanced segmentation capabilities.
They're Too Expensive
Opensend’s pricing can be expensive, especially for higher traffic sites.
Highest True Match Rate by Far
Opensend claims an impressive 25-35% “Match Rate” for their Website Visitor ID but match rate alone is misleading—it can be inflated simply by returning more emails, even if most are incorrect.
What really matters is True Match Rate—what percentage of known, validated website users correctly identified?
Our studies show that Customers.AI’s True Match Rate is 2-18x higher than Opensend because far fewer of their “matches” actually check out, indicating serious data quality issues!
Opensend said you were their biggest competitor. They set up a trial for us and they went into Klaviyo and set up their own campaigns for their own abandoned cart campaigns. They accidentally were actually emailing everyone July 4th promos for November.

Opensend’s bad data is costing you thousands!
Better Data & Integrated Tools for Visitor ID Marketing
Opensend dumps low-quality data into third-party ESPs, leaving you to handle poor engagement and deliverability risks while providing only data, not tools, at the cost of email performance.
Customers.AI delivers higher-quality visitor ID data with the flexibility to send it to an ESP or use our built-in marketing tools—including email automation, segmentation, customer journeys, deliverability optimization, postcard sending, and ad platform integrations like Google, Meta, and TikTok.
The result? More accuracy and more ways to leverage visitor ID data—without ESP compliance risks.
Opensend Has Yet to Match Our Data in Head-to-Head Tests
In a blind test run by a third-party CDP, Customers.ai was shown to have a 65-85% data accuracy rate while the other top vendors, including Opensend, struggled to reach 30% accuracy.
It’s not their fault. Like most identity resolution tools, Opensend licenses their data from bad sources. They don’t even know how poor the data being provided to them is because it’s behind a black box!
Customers.ai’s proprietary database combined with our first-party validation tools, ensures the names, emails, and contact information provided are accurate.
The result? Your emails won’t be marked as spam, your domain won’t be penalized, and you won’t hurt your sales.
Accuracy of Top 3 ID Resolution Providers
Protect Your Sender Reputation with Our Integrated Visitor ID + Email Sending Solution
While Opensend integrates with hundreds of third-party ESPs, sending emails to contacts sourced from low-accuracy data can be risky, potentially triggering spam complaints and hurting your sender reputation.
Instead of dumping your third-party data into your ESP and potentially skewing your complaint rate, we offer a fully compliant solution.
We’ll send the emails for you, so there’s no need to mix identity resolution data with your first-party customer data.

Customers.ai vs Opensend FAQs
Can you tell me more about Opensend’s cost?
Revenue Roll’s pricing starts at $499 per month for up to 10,000 identified visitors, making it one of the more expensive options in the market. For larger businesses, the Enterprise plan costs $8,999 per month, which can be a steep commitment. This tiered pricing structure can escalate quickly as your business grows, making it less accessible for smaller companies or those seeking cost-effective scalability.
What do Opensend reviews say about the platform?
While some users appreciate Revenue Roll’s ability to identify visitors, reviews often mention challenges with data quality and limited feature sets. Users report that its primary value lies in retargeting, but it falls short in providing the flexibility and robust integrations needed to execute broader marketing strategies. Customers.ai, in contrast, delivers enriched data alongside seamless omnichannel integrations, ensuring your marketing efforts are more comprehensive and effective.
Who are Opensend’s competitors?
Revenue Roll competes with platforms like Customers.ai, Retention.com, Opensend, and 17hats. However, unlike its competitors, Revenue Roll lacks advanced visitor identification features, dynamic email marketing capabilities, and the comprehensive sales automation tools offered by Customers.ai. This makes it less appealing for businesses looking for an all-in-one solution.
Does Opensend integrate with Klaviyo?
Revenue Roll does integrate with Klaviyo, but its functionality is limited to basic data syncing for retargeting. It doesn’t offer the deeper integration capabilities and advanced segmentation options that Customers.ai provides, which are essential for creating high-performing omnichannel campaigns.
Does Opensend have an API?
Revenue Roll does not appear to offer an API, which can be a significant limitation for businesses that rely on custom workflows or advanced integrations. Customers.ai, on the other hand, includes API access to ensure maximum flexibility and compatibility with your existing systems.
Does Opensend integrate with Shopify?
Revenue Roll integrates with Shopify, but the features are relatively basic compared to the depth of Shopify integrations provided by Customers.ai. Customers.ai’s tools not only sync data but also allow for advanced visitor identification and personalized engagement, giving businesses a stronger edge.
Is Opensend legal?
Revenue Roll operates within the bounds of consumer privacy policies and emphasizes legal compliance in its operations. The platform focuses on identifying users who have opted into first-party (cookie) tracking and ensures that any data shared aligns with the highest quality data brokers and credit agencies. This approach underscores Revenue Roll’s commitment to adhering to legal standards and protecting consumer privacy.
