1. Lindy – Best AI outreach tool overall

Lindy lets you build custom AI agents that handle your entire outreach process, from enriching a lead to following up with them across channels.

You can automate sales, support, and recruiting outreach with custom AI agents that act like flexible sales development representatives (SDRs). You can assign them tasks like researching leads, sending personalized follow-ups, updating CRMs, or even replying to emails.

How we tested these AI outreach tools

We tested how each tool fits into daily sales tasks like prospecting, follow-ups, and CRM sync.

What we looked for:

• Ease of setup and use: A tool that needs a week and two engineers to launch a campaign won’t work for most sales teams.
• Automation depth: We checked if each tool could run multistep campaigns with follow-ups, branching logic, and CRM updates.
• Data quality and deliverability: We tested email validation accuracy, inbox rotation, and how well tools handled enrichment and bounce mitigation.

Our testing process

We tested each platform by running real campaigns, including cold outreach, follow-ups, and CRM syncs. We used dummy domains to test deliverability and track response rates across different industries and ICPs.
