Apollo

If you sell to businesses, Apollo is one of the first places worth opening. It pairs a large searchable database of companies and contacts with the tools to actually reach them, so you can build a list, enrich it and launch an email sequence without bouncing between tabs.

In our tests, the filters were the real highlight: job title, company size, industry and tech stack narrow things down quickly. The AI writing help drafts reasonable first emails, though we still rewrote the openers to sound like ourselves.

The free plan is generous enough to get a feel for it, while paid tiers from $49/mo unlock more credits and automation. Data accuracy varies by region and niche, so we'd verify emails before sending big batches.
