Email marketing covers all emails sent for commercial purposes: newsletters, offers, follow-ups, or prospecting. Its principle is to use email to keep a relationship going with an audience and, over time, generate sales. It's one of the most direct and least expensive channels, provided it's done well.
Its main forms
Email marketing spans several uses. The newsletter keeps the link alive with contacts who already know you. Promotional emails push an offer at a given moment. Follow-ups revive a cart or an ongoing conversation. And cold email addresses people who don't know you yet. They all share the same medium, but the tone and legal frame differ depending on whether the recipient has already given consent.
The rules to follow
Whatever the form, three principles hold. Offer a simple, one-click unsubscribe, and honor it. Write only within a legitimate frame, accounting for opt-in where it applies. And tend to deliverability, because a perfect email is useless if it lands in spam. Following these rules isn't just an obligation: it's what protects your ability to reach inboxes over time.
