Why Email Marketing is Critical for Startups and SMEs
Marketing is often the hardest part of a startup journey, not building the product, not creating the team. Why? Because marketing validates whether there's even a demand for what you're offering. Email still boasts the highest ROI among marketing channels: For every $1 spent, businesses earn an average return of $36. But without automation, email marketing can quickly become overwhelming.
That’s where tools like HubSpot and Mailgun step in, automating the heavy lifting and allowing your team to focus on creativity and strategy.
