When Jake’s e-commerce business hit $2M in annual revenue, his email marketing platform bill jumped to $899/month. “There has to be a better way,” he told me over coffee last week. Three months later, after switching to Brevo’s Aura AI, he’s saving $6,400 annually while his email revenue increased by 34%.
Jake’s story isn’t unique. Across industries, businesses are discovering that traditional email tools – no matter how “advanced” they claim to be – simply can’t compete with true AI-powered platforms.
But here’s the challenge: every email platform claims to have “AI features.” How do you separate marketing hype from genuine intelligence? Today, I’m sharing the most comprehensive comparison between Brevo’s Aura AI and traditional email tools, backed by real data from 47 businesses that made the switch.
