1. Why Email Marketing Still Matters for Small Businesses

Many small-business owners assume email marketing is outdated compared to social media or paid ads — but the data tells a different story.

  • ROI averages $42 for every $1 spent (according to DMA).
  • 81% of SMBs rely on email as their primary customer-acquisition channel.
  • Unlike social media algorithms, you own your list — direct access to your customers.

Email marketing allows you to:
✅ Stay top-of-mind with existing customers
✅ Build loyalty and repeat purchases
✅ Announce offers, events, or updates
✅ Automate communication to save hours every week

In 2025, with automation, AI-assisted personalization, and tighter privacy laws, the right email tool can help you deliver targeted, human-like communication that actually converts.


2. What to Look for in an Email Marketing Tool

Choosing the right tool means understanding what matters most to small businesses — simplicity, automation, scalability, and value.

Here’s what to evaluate before you commit:
