Seamless.AI and ZoomInfo share many similarities. Both platforms promise to let you tap into your target market by finding the data you need and send out highly personalized emails that maximize the reply rate. They also automate many tedious tasks, saving you time and money.
Still, these two solutions differ in several key aspects. To help you identify them, we took a close look at both platforms’ features and sought opinions from marketing and sales experts in our network. The result is a detailed Seamless.AI vs. ZoomInfo comparison that’ll help you decide which option to choose.
We’ll also introduce a third option you should consider as it addresses some of the main drawbacks of these two platforms while holding onto their strengths. 🏋️
ZoomInfo vs. Seamless.AI—Main Differences Explained
After putting ZoomInfo and Seamless.AI head-to-head, we’ve decided to compare them across four factors that matter the most:
- Data sourcing and availability
- Additional features
- Ease of use
- Pricing
🔎 Data Sourcing and Availability
Seamless.AI and ZoomInfo give you access to lots of B2B data, though they take different approaches to providing it. ZoomInfo adds contacts and other information to its database, while Seamless.AI performs real-time searches.
In theory, this gives Seamless.AI a slight edge because there’s a smaller risk of data getting stale. The company prides itself on over 1.9 billion contacts and company records verified in 2023, though this doesn’t always translate into satisfactory real-life results. Some users claim that 30%–40% of the provided data is inaccurate, which makes for a low hit rate.
ZoomInfo is undoubtedly comparable to Seamless.AI in terms of the available data. Its database contains the following:
- 260+ million published professional profiles
- 100+ million published company profiles
- 135+ million verified phone numbers
While these numbers seem impressive, the data accuracy issue is still present. There have been reports of ZoomInfo’s data getting increasingly inaccurate, especially when it comes to phone numbers.
In all fairness, no sales engagement platform can guarantee 100% data accuracy, and the above complaints don’t necessarily reflect the general experience you should expect with either platform. Many users have found lots of valuable contact information with both solutions, but you should beware of the aforementioned risks before making the final choice.
Winner: It’s a tie 🏅
➕ Additional Features
When it comes to feature availability, ZoomInfo knocks Seamless.AI out of the park. That’s because the platform encompasses a collection of four products, as shown in the following table:
It’s clear that ZoomInfo is a robust solution that lets you expand your workflow far beyond prospecting and outreach. SalesOS is particularly useful for your outbound campaigns because it’s packed with features, such as:
- AI-powered conversation intelligence
- Email and phone outreach automation
- Contact tracking
- Lead scoring
Seamless.AI is far more focused on prospecting, which is a double-edged sword. On the bright side, you’ll pay significantly less for it (more on that later), but you also don’t get an all-in-one solution offered by ZoomInfo. Instead, you get a set of specialized features, most notably:
- Pitch intelligence—A form of data enrichment that helps you target prospects using their specific information and updates
- Autopilot—An AI-powered lead list builder that removes lots of manual labor
- Buyer intent data—Qualifies leads based on over 12,000 intent signals
- Writer—An AI writer that creates different types of content (emails and replies, social posts/comments, cold call scripts, etc.)
While the above features are useful, ZoomInfo offers most of them and so much more. It’s a more well-rounded platform since it reduces the need for additional tools.
Winner: ZoomInfo 🏆
⚙️ Ease of Use
The upside of Seamless.AI’s narrower feature spectrum is better user-friendliness. The platform features a clean UI that’s easy enough to navigate whether you’re only getting started with sales engagement platforms or have prior experience.
Searching and filtering leads is easy and intuitive, as reported by the platform’s users. If you do find anything unclear, you can use quick tutorials and video guides for help.
As expected, ZoomInfo feels a lot busier. This isn’t necessarily a bad thing if you know your way around sales engagement platforms, but beginners will most likely face a significant learning curve before getting the hang of the platform’s features.
ZoomInfo’s team offers onboarding to help you get started, but some users weren’t happy with it. One customer said they had to spend 20–30 hours watching webinars to start using ZoomInfo, while support was underwhelming.
Winner: Seamless.AI 🏆
💰 Pricing
ZoomInfo and Seamless.AI share a major disadvantage—non-transparent pricing. Neither platform offers any specific details on its website, so you need to reach out and get a quote.
What we do know is that ZoomInfo offers three pricing plans:
- Professional+
- Advanced+
- Elite+
The pricing also depends on the specific add-ons you’ll use, as well as the depth of information you’re looking for. If you need a reference point, ZoomInfo states an average customer spends $30,000 on SalesOS annually, which is an astronomical amount of money for many businesses.
Unlike ZoomInfo, Seamless.AI offers a free plan, which gives it a massive advantage. You get 50 credits to test the platform’s enrichment, as well as limited access to its core features. If you want to upgrade, you can choose between three tiers:
- Basic
- Pro
- Enterprise
According to existing users, Seamless.AI comes at a fraction of ZoomInfo’s cost. Specifically, one customer said it’s only 10%–15% of ZoomInfo’s average price, so it goes without saying that Seamless.AI is a much better option for users on a budget.
Winner: Seamless.AI 🏆
The Verdict—Should You Use ZoomInfo or Seamless.AI?
ZoomInfo and Seamless.AI are both solid platforms, and neither option is universally better than the other—it all comes down to your individual factors. To sum up our findings:
- If you need a robust platform with lots of features and have a sizeable budget, ZoomInfo might be better
- If you don’t want to pay five figures a year for a sales engagement platform and need a more specialized solution without a bunch of bells and whistles, you might be better off with Seamless.AI
Unfortunately, there’s an issue you won’t be able to avoid regardless of your choice—upfront investments without guarantees that you’ll get the data you’re looking for. This is a common problem with all single-source data providers, and it can be highly frustrating.
Let’s say you sign up for either platform and pay the annual fee. A couple of weeks or months go by, and you realize the hit rate is nowhere near what you expected. You’re still tied up in the contract, so you have two options—get the most of the data you have or spend even more money on another platform.
Nobody wants to find themselves in this position, which is why many experts avoid platforms like ZoomInfo and Seamless.AI altogether. Instead, they go with a platform that lets them access multiple providers at once and maximize data coverage.
