What's the best email outreach tool for solopreneurs?

Hey everyone, I recently wrote an article on what I think is the best email outreach tool for solopreneurs (I think it's Smartlead hehe). Curious on what other people's thoughts are? I go into detail of what I think below but would love to get other's opinions on it. I'm super interested in Ava as an email outbound tool. https://solounicornsclub.beehiiv.com/p/unlocking-success-solopreneurs-smartlead-ai-vs-lemlist?_gl=1*1polf58*_ga*MjA2NTk4MzA1MC4xNzAzMDYzMzkw*_ga_E6Y4WLQ2EC*MTcwNzY1OTg0My4yMy4xLjE3MDc2NjA3OTEuNTAuMS4xMTM1Mjk2Mjgz*_gcl_au*MTYxOTE0MjQ0LjE3MDMwNjMzOTA.
