Email & Automation
Email Marketing
Definition
Email marketing is the practice of sending targeted, personalised emails to a subscriber list to nurture leads, retain customers, and drive purchases — delivering an average ROI of 42:1, the highest of any digital marketing channel.
What is Email Marketing? — Detailed Explanation
Email marketing sends commercial messages to opted-in subscribers — newsletters, promotional campaigns, transactional messages (order confirmations), and automated behavioural sequences triggered by user actions.
Unlike social media's algorithm-limited reach, email gives direct access to subscribers who have explicitly opted in. This owned-channel dynamic means email is not subject to algorithm changes or platform outages — your list is an owned asset that compounds in value.
Effective email combines segmentation (different messages by demographics, purchase history, or engagement), personalisation (using name, company, past purchases), and automation (trigger-based sequences responding to subscriber actions).
Email deliverability — reaching the inbox rather than spam — requires domain authentication (SPF, DKIM, DMARC), list hygiene (removing inactives), low complaint rates, and quality content. A 25%+ open rate is the benchmark.
Key Points — Email Marketing Summary
- Average ROI: 42:1 — highest of any digital marketing channel
- Owned channel — not subject to algorithm changes or platform risk
- Segmentation + personalisation increases revenue per email by 40–60%
- Automated sequences (welcome, cart recovery, re-engagement) run 24/7
- Deliverability requires SPF/DKIM/DMARC setup and regular list hygiene
- Open rate benchmark: 25%+ is good; below 15% signals deliverability issues
Examples & Use Cases
An online course platform segments into "new subscribers", "active learners", and "inactive users" — each receiving tailored sequences. Segmentation increases overall revenue per subscriber by 60%.
A SaaS company's bi-weekly newsletter to 10,000 subscribers at 38% open rate generates 50–80 trial activations and 5–10 paid upgrades per send — their second-highest revenue channel.
Email Marketing — Frequently Asked Questions
