Drip Campaign
An automated sequence of emails sent on a predetermined schedule to nurture leads or onboard new users.
A drip campaign is an automated series of pre-written emails sent to subscribers or customers at predetermined intervals, triggered by specific actions or time-based rules. The term "drip" refers to the gradual, steady delivery of content — like water dripping from a faucet — rather than sending everything at once.
Drip campaigns serve various purposes throughout the customer lifecycle: welcome sequences for new subscribers, onboarding flows for new users, lead nurturing for prospects, re-engagement campaigns for inactive users, and post-purchase follow-ups. Each email in the sequence builds on the previous one, progressively moving the recipient toward a desired action.
The power of drip campaigns lies in their combination of personalization and automation. Once configured, they deliver the right message at the right time without manual effort. Modern email platforms enable sophisticated branching logic — if a recipient opens email 3, they receive email 4a; if they do not, they receive 4b. This conditional flow personalizes the experience based on actual engagement behavior.
Testimonials are among the most effective content elements in drip campaigns. Including a customer quote in a welcome email builds immediate trust. Adding a video testimonial to a lead nurturing sequence can push hesitant prospects over the conversion threshold. Post-purchase drip campaigns that showcase customer success stories reinforce the buying decision and reduce buyer's remorse. The key is matching testimonial content to the recipient's stage — early-stage prospects need broad credibility signals, while later-stage prospects need specific, relevant success stories from similar companies.
Frequently Asked Questions
How many emails should a drip campaign include?
Campaign length depends on the goal and audience. Welcome sequences typically include 3-5 emails over 1-2 weeks. Lead nurturing campaigns might span 5-10 emails over 3-6 weeks. Onboarding drips can include 7-12 emails over the first 30 days. The right number is the minimum needed to achieve the campaign's goal without fatiguing recipients. Monitor unsubscribe rates and engagement metrics after each email — if engagement drops sharply at email 6, your campaign may need to be 5 emails.
How do you include testimonials in drip campaigns?
Place testimonials strategically based on campaign stage. In welcome emails, include a brief customer quote that validates the sign-up decision. In nurturing sequences, feature case study summaries with specific results relevant to the lead's industry. In conversion emails, embed video testimonial thumbnails that link to the full video. In post-purchase drips, share success stories from customers at similar stages. Always use testimonials from customers who match the recipient's profile for maximum relevance.
