In one sentence: Email marketing is sending targeted messages directly to a list of subscribers who've opted in, remaining one of the highest-return marketing channels available.

Despite the rise of social media, email marketing has consistently remained one of the highest-ROI marketing channels โ€” largely because an email list is owned directly by the business.

Why Owning the List Matters

Social media followers are subject to a platform's algorithm deciding whether they even see your posts. An email list bypasses that entirely โ€” a message arrives directly.

๐Ÿ’ก Did You Know?

Email marketing is consistently cited across industry studies as delivering one of the highest returns on investment of any digital marketing channel, often ahead of social and paid search.

Frequently Asked Questions

Why is email marketing still relevant with social media available?

Unlike social followers, an email list is owned directly by the business โ€” not subject to a platform's algorithm deciding who sees your message.

Is it legal to email anyone who gives you their email address?

No โ€” regulations like CAN-SPAM and GDPR require clear consent and an easy way to unsubscribe.

What's a good email open rate?

This varies significantly by industry, but averages commonly fall in the 15-25% range โ€” context and list quality matter more than a universal benchmark.

What is an automated email sequence?

A pre-written series of emails triggered by an action, like signing up, sent automatically over a set schedule.

How often should a business email its list?

It varies by audience and content type, but consistency matters more than frequency โ€” a predictable, valuable cadence performs best.

What's the difference between GDPR and CAN-SPAM?

CAN-SPAM is U.S. email regulation; GDPR is broader EU data protection law that also covers email consent requirements.

Can email marketing work without a large list?

Yes โ€” a smaller, genuinely engaged list often performs better than a large, disengaged one, since relevance drives results more than size.
