Flexible Workflows That Save Hours
What I like about Clay is that it feels flexible without being a mess. We set up a table that pulls in companies, enriches job changes, and scores leads with AI prompts, and once it was dialed in it saved my team hours every week

Premium Tool That Pays Off for Serious Outbound
ZoomInfo is expensive, so I would not call it a casual tool, but for a sales team doing serious outbound it earns its spot. The Chrome extension is genuinely useful when I am on LinkedIn, and the export process into Salesforce has been pretty smooth for us

Great value for money, does what it says on the tin. It's a little clunky in places i.e with the workflows and automated list pulls from linkedin. Sometimes it's hard to tell whether it's pulled these properly and then put them in the CRM. Only works for linkedin as far as I'm aware, would be good to have it working when you visit a website, if it pulled the company and you could search through that way that would be ideal.

Fast LinkedIn Prospecting via Chrome Extension
Lusha has been solid for building outbound lists fast, especially with the Chrome extension pulling contact details straight from LinkedIn profiles. It does not get every number right, but the hit rate has been good enough that my team spends less time guessing and more time actually reaching people

Get deal for freeFullEnrich is a B2B data enrichment platform built around “waterfall” enrichment: it checks multiple premium data vendors to maximize the chances of finding accurate work emails and mobile numbers. What makes it stand out is the combination of multi-source coverage, strong deliverability safeguards (like multi-step verification), and workflow flexibility via API, bulk CSV enrichment, and automations through tools like Zapier/Make. Next, I’ll break down the pros, cons, best-fit users, and alternatives to consider.
