A drip campaign (also called a drip sequence or nurture sequence) is a series of pre-written emails automatically sent to contacts at set intervals, typically triggered by a specific action such as signing up to a newsletter, downloading a resource, or requesting a free trial. The 'drip' metaphor refers to content being delivered at a steady pace over time, rather than all at once. Drip campaigns are the primary mechanism through which email marketing nurtures cold leads into warm prospects — and warm prospects into paying customers.
The core purpose of a drip campaign is to build familiarity, trust, and purchase intent over time in an audience that is not yet ready to buy. Research on B2B buying behaviour consistently shows that 80%+ of leads who will eventually buy from a business are not ready at the point of first contact — they need education, relationship building, and repeated exposure before they are comfortable making a decision. Drip campaigns automate this relationship-building process.
Types of drip campaigns
- Lead nurture drip — educates prospects about a problem and your solution, building toward a sales conversation or purchase
- Onboarding drip — guides new customers through product features or service processes, reducing churn and increasing activation
- Re-engagement drip — sent to inactive contacts to rebuild engagement before removing them from the list
- Educational drip — delivers a mini-course or serialised content across multiple emails, building authority and engagement
- Promotional drip — builds toward a launch or sale with countdown content, early access, and urgency messaging
- Upsell/cross-sell drip — sent to existing customers at the right point in their lifecycle to introduce complementary products or services
The most effective drip campaigns are built with clear decision points: if a contact opens email 3 and clicks the link, they enter a more sales-focused branch; if they ignore it, they continue the educational track. This conditional logic (available in platforms like ActiveCampaign, Klaviyo, and HubSpot) allows a single drip campaign to serve a heterogeneous audience with appropriately personalised content based on engagement behaviour.
A drip campaign is an automated sequence with a defined endpoint — it runs for a fixed number of emails delivered over a set period after a trigger event. An email newsletter is a recurring broadcast sent to all active subscribers on a regular schedule (weekly, monthly). A new subscriber might receive your 5-email welcome drip over their first two weeks, then transition to receiving your regular weekly newsletter. Both serve different purposes: drip campaigns nurture and convert; newsletters maintain relationship and deliver ongoing value.
Length depends on the sales cycle and the educational depth required. For e-commerce (short buying decisions), a 3–5 email drip over 1–2 weeks is typically sufficient. For B2B or high-consideration services (longer decision cycles), a 6–12 email drip over 4–12 weeks may be appropriate. The best test is tracking engagement by email number — if open rates drop sharply after email 4, the sequence is too long. If contacts are converting primarily from email 6+, earlier emails may be too soft on the commercial message.
