Instantly is one of the most popular cold email tools: unlimited sending accounts with warm-up, a large B2B lead database and AI agents for writing and replies. LeadGen.tools takes another route: you paste your website and it decides who to sell to, finds real companies (including small local ones), finds the person who decides at each one and writes a different email for every prospect.
Here is an honest look at both, with prices checked on October 1, 2026.

Where Instantly is the better choice
- Volume. Up to 500,000 emails a month on the biggest plans, unlimited inboxes and warm-up included.
- A large B2B database with filters by role, industry and company size.
- Agencies sending for many clients from many domains.
Where LeadGen.tools is the better choice
- You don’t know exactly who to sell to. It reads your website and proposes your best customer segments, ranked, never your competitors.
- Local and small businesses. Clinics, shops, agencies and contractors that are on maps but often missing from B2B databases.
- One email per prospect written for that company, plus follow-ups, without writing prompts.
- Small volumes at a small price. Free plan, then $24.99/month; you pay per prospect contacted, not per email.
- LinkedIn and WhatsApp through your own AI agent, with limits built in (see how).
Can you use both?
Yes. Some people find the companies, the decision makers and the emails with LeadGen.tools and export them to the tool they already use for sending. Exporting costs 2 credits per company; sending with LeadGen.tools costs 1, follow-ups included.
