Email marketing is far from outdated—in fact, it’s booming. With over 4.7 billion email users expected by 2026, startups and digital entrepreneurs are quickly realizing that email isn’t just alive—it’s evolving fast. The surge in remote work, creator-led businesses, and automation-first marketing has opened up massive opportunities in the email marketing app niche.
From AI-powered newsletters to e-commerce-focused automations, the ecosystem is brimming with gaps ready to be filled. If you’re a founder or agency looking for the next big move, launching an email marketing app in 2025 could be your golden ticket.
In this blog, we’ll break down why these apps are red-hot right now, which ideas are worth pursuing, how much it costs to launch, and how clone app development from Miracuves can save you months of time and budget.
Why Email Marketing Apps Are a Hot Opportunity in 2025
According to Statista, email marketing revenue is projected to surpass $17.9 billion by 2027, with constant annual growth.
