ZoomInfoZoomInfo makes it much easier to identify decision-makers, prioritize high-value accounts, and keep pipelies moving. With powerful AI automation and high-quality data, it's an all-in-one solution for sales, marketing, and RevOPs teams who want to save time and drive revenue growth.
As a B2B database, ZoomInfo certainly has a lot to offer. Its detailed business information on people and companies is impressive, and I've found it to be a useful resource for researching potential clients and partners.
However, I do have a few criticisms of the product. Firstly, its pricing is quite steep, especially compared to other B2B databases on the market. This makes it difficult for smaller businesses or startups to justify the cost. Additionally, while the information on ZoomInfo is generally accurate and up-to-date, I have come across a few instances where the information was incomplete or outdated.
Despite these drawbacks, ZoomInfo is still a good resource for business information. It just might not be the best option out there. If you're willing to pay for a premium service, then ZoomInfo could be worth considering. However, if you're looking for more cost-effective alternatives, there are several options to consider.

Skip ZoomInfo for this use case. It's enterprise-contract priced, built for outbound prospecting from company lists, and adds zero value for personal email resolution. Same story with Lusha — excellent for Chrome extension-style lookups starting from a LinkedIn profile, wrong tool for an automated inbound pipeline. - Source: dev.to / 3 months ago
Most SDR stacks start with a contact database — ZoomInfo, Apollo, or Lusha — and treat enrichment as a one-time step at the top of the funnel. The problem: these databases are 3–18 months stale on average. Job titles change. Companies restructure. Decision-makers who were Director of Engineering in Q1 are VP by Q3. - Source: dev.to / 4 months ago
Kaspr is the most LinkedIn-native option on this list. The Chrome extension sits on LinkedIn profiles and exports contact data directly — phone numbers, emails, and CRM sync. 120M+ European contacts is their differentiator; US coverage is noticeably thinner. Starting at $74/month, it's not cheap for light usage, but teams running 200+ LinkedIn outreach touches per month will find the unit economics work. Kaspr is... - Source: dev.to / 4 months ago
For the phone calls - there's a decent chance they got your number from zoominfo.com - you can go there and request to be removed. Source: about 3 years ago
I just found a few data collator sites, zoominfo.com and signalhire.com are just two - they seem to scrape sites like Linkedin etc and collate everything. Personal numbers can be found pretty easily, if you've ever signed up for a business identification number it could be there, could be in a data leak somewhere - these companies are pretty shady and will buy data from places to just get a lead.

React Testing Library’s core philosophy is that we should write our tests in such a way that we simulate user behavior. By testing what the user can actually do, our tests focus less on implementation details and more on the actual user interface, which leads to less brittle tests and a more reliable test suite. - Source: dev.to / 7 months ago
In the main branch, we set up Vitest as the test runner and React Testing Library for rendering the component and simulating user interactions. We also set up MSW to intercept the network requests and return mock responses. - Source: dev.to / 11 months ago
React Testing Library (RTL) provides lightweight utilities built on top of react-dom and react-dom/test-utils, designed to promote testing through user interactions rather than component internals. Instead of working with component instances, RTL encourages querying and asserting against actual DOM nodes, just like real users would. This approach improves test reliability and pushes developers toward writing more... - Source: dev.to / about 1 year ago
Testing ensures code reliability and maintainability. Jest, Vitest and React Testing Library are standard tools for unit and integration testing. Unit tests verify individual components, while integration tests ensure features work together. For example, testing a TodoList component might involve:. - Source: dev.to / about 1 year ago
Additionally, I wrote Jest and Enzyme unit tests to demonstrate how to go about unit testing the components, as test driven development (TDD) is another methodology my organization subscribes to. Jest is a unit testing framework that actually shipped with React if you use the Create React App CLI to make a new React project. And at the time, Enzyme was created by Airbnb and added additional functionality to Jest... - Source: dev.to / over 1 year ago
