Definition

Email marketing is a digital marketing strategy that uses email to promote products, services, or content to a targeted audience. It involves sending commercial messages to people who have opted in to receive communications from your brand.

Common Use Cases

Send promotional campaigns to announce sales and new products

Nurture leads with automated drip sequences

Deliver newsletters with valuable content to subscribers

Re-engage inactive customers with win-back campaigns

Send transactional emails like order confirmations and receipts

Why Email Marketing Matters

Email marketing delivers an average ROI of $36-$42 for every $1 spent, making it one of the most cost-effective marketing channels. Unlike social media, you own your email list and have direct access to your audience without algorithm interference. With 4 billion daily email users worldwide, email remains one of the most reliable ways to reach customers.

How Email Marketing Works

Effective email marketing starts with building a quality subscriber list through opt-in forms. You then segment your audience based on behavior, preferences, or demographics to send relevant content. Email service providers (ESPs) help you design, automate, and track campaigns while managing deliverability to ensure your messages reach inboxes.

Best Practices

Build your list organically - never buy email lists

Use double opt-in to ensure subscriber quality

Segment your audience for personalized messaging

Verify email addresses to maintain list hygiene

Monitor deliverability metrics and keep bounce rates below 2%

Include clear unsubscribe links in every email

Frequently Asked Questions

What is a good email open rate?

The average email open rate across industries is 20-25%. However, rates vary significantly by industry - B2B emails often see 15-20%, while retail may see 25-30%. Focus on improving your rates relative to your own benchmarks.

How often should I send marketing emails?

Most brands find success with 1-4 emails per week. The key is consistency and value - subscribers prefer regular, valuable content over sporadic promotional blasts. Test different frequencies to find what works for your audience.

Why do my emails go to spam?

Emails land in spam due to poor sender reputation, high bounce rates, spam trigger words, or lack of proper authentication (SPF, DKIM, DMARC). Regularly verify your email list and maintain good list hygiene to improve deliverability.
