Why Email Marketing Tools Are Still Your Brand’s Best Revenue Driver
No marketing channel guarantees revenue, but email—powered by the right email marketing tool—comes impressively close. According to Litmus, email delivers a jaw-dropping $36 for every $1 spent.
Here’s why email marketing tools are dominating the scene:
- Apple’s privacy changes have disrupted paid social targeting, making owned channels even more critical.
- Data privacy laws are tightening across the US and globally, pushing brands to move away from third-party data.
- Email earns permission. Unlike passive social ads, email reaches shoppers ready to engage.
For B2C brands focused on building customer relationships, email remains the smartest way to drive repeat revenue. But today, blasting your entire list with the same promotions is outdated. Modern platforms like Klaviyo, one of the leading email marketing tools, empower you to personalise messaging at scale, integrate customer data across channels, and automate flows intelligently.
Ready to future-proof your email strategy? Here are 8 essential email marketing tools and features you should demand in 2025 — especially if you’re using Klaviyo, but also applicable to Mailchimp, Zoho, and beyond.
