Email marketing
Email marketing is the practice of sending targeted, commercial or educational email messages to a list of subscribers or customers to build relationships, promote offerings, and drive specific actions. It is one of the oldest digital marketing channels and, measured by ROI, consistently one of the most effective. Unlike paid advertising, email marketing communicates with people who have already expressed some level of interest by subscribing, purchasing, or sharing their contact details. That existing relationship is the foundation of email’s effectiveness: you are not interrupting strangers, you are continuing a conversation with people who want to hear from you.
Email marketing spans a wide spectrum of communications: newsletters that build ongoing engagement, promotional campaigns that drive direct response, automated nurture sequences that move prospects through the funnel, transactional emails that confirm purchases or deliveries, and lifecycle campaigns that onboard, retain, and re-engage customers. Each serves a different purpose and requires different content, design, and measurement approaches.
For B2B marketers, email remains the primary owned marketing channel. It is the mechanism through which leads are nurtured into pipeline, customers are onboarded and expanded, and the audience that content marketing builds is converted into revenue. The combination of low cost, high reach, measurability, and the ability to personalise at scale makes email marketing foundational to virtually every B2B marketing programme, regardless of the organisation’s size or sector.
What is the average ROI of email marketing?
Email marketing consistently achieves high ROI relative to other channels. Frequently cited figures suggest returns of 36 to 42 dollars for every dollar spent, though actual ROI varies significantly depending on the quality of the contact list, the relevance of the content, the maturity of the programme, and the industry. B2B email marketing ROI is harder to measure precisely because the sales cycle is longer and attribution is more complex, but email typically contributes significantly to marketing-influenced pipeline.
What are the main types of email marketing campaigns?
The main types include: newsletters (regular content sends to an engaged audience), promotional emails (time-sensitive offers or announcements), automated nurture sequences (pre-built email flows triggered by contact behaviour), welcome emails (sent to new subscribers or customers), re-engagement campaigns (targeted at inactive contacts), transactional emails (triggered by specific actions like purchases or registrations), and lifecycle emails (targeted at specific stages of the customer journey).
What makes B2B email marketing different from B2C email marketing?
B2B email marketing typically involves longer sales cycles, multiple decision-makers, higher-value transactions, and more content-intensive nurture sequences. B2B emails tend to be more informational and less promotional, focused on building trust and demonstrating expertise rather than driving impulse purchases. The metrics also differ: open and click rates matter, but pipeline influence and revenue attribution are the ultimate measures of success. B2C email marketing is often more volume-driven with a greater emphasis on promotions, discounts, and immediate conversion.
