Use Cases
These two platforms have different approaches to lead generation – 6sense focuses on account-based marketing tactics, while Apollo.io focuses on targeting individual contacts. Here are some use cases to better understand each approach.
6sense
Account-based marketing allows for account-level information rather than (or in addition to) individual contact details. This approach lets sales teams tackle teams or companies versus individuals within a business. With intent data, 6sense makes it easier to identify accounts or businesses that may be in a position to buy.
For example, a B2B software company may specialize in enterprise-level cybersecurity solutions. They may target accounts rather than individual decision-makers because the solutions they provide are company-wide. 6sense would help create a curated list of accounts and personalized content development for those target accounts.
Apollo.io
Apollo.io is less focused on account-based marketing and sticks to individual contacts to reach out to. The tried and true lead generation method gives you a curated, accurate list of contacts to reach out to individually. The platform also includes built-in outbound marketing tools, meaning you can leverage Apollo for more than just your contact lists – you can launch outreach campaigns from the tool.
A digital marketing agency may be able to leverage Apollo to quickly identify key contacts within small to medium businesses in their area (typically contacting CEOs, marketing managers, etc.) Apollo allows sales teams to create a highly accurate contact list and send outbound emails right from the same tool.
Database & Reliability
Both databases offer an impressive number of contacts (over 400 million in the 6sense database and over 200 million in Apollo’s). With the size of these databases, you’ll typically see similar data structures, accuracy, and availability of data, but let’s do a quick comparison.
6sense
6sense states Free plan access to 270 million B2B profiles, 100 million emails and 50 million direct dials. The company does not publish an overall database accuracy rate.
In terms of the data you receive, similar to Apollo, you’ll see name details, emails, phone numbers, and general company information.
Apollo.io
While Apollo.io’s is half the size of 6sense, over 200 million contacts is still a large enough global database to meet most businesses’ needs. Apollo states verified emails have an accuracy rate of more than 90 percent and cites a 91 percent figure in its verification documentation. However, user reviews may indicate a less accurate dataset.
Apollo has been working to continually integrate AI into their data farming and validation processes in an effort to increase data accuracy. Apollo offers standard contact details, including name, email address, phone number, and general company details.
One positive note on the data accuracy concerns – Apollo refunds the email credit if an Apollo verified email bounces within 30 days and the email was sent inside Apollo.
Pricing for 6sense vs. Apollo
While price isn’t everything when it comes to choosing a lead generation platform, it may be a deciding factor for many businesses. Let’s take a look at what each platform costs and what you’ll get with each.
6sense
6sense now publishes a pricing page that includes a Free plan with 50 data credits per month and additional paid plans with credit based tiers. Detailed plan pricing for higher tiers is still delivered via sales.
While it’s understandable the pricing may vary depending on needs and features, in a world where there is so much transparency in pricing, not publishing pricing may deter potential customers. Additionally, there is no free trial available, meaning customers have no sense of pricing or if the product is fit for purpose.
