Drip Campaign

GlossaryCold outreachUpdated March 23, 2026

Definition
An automated email sequence that sends pre-written messages to prospects at scheduled intervals to nurture them through the sales funnel.

A drip campaign is an automated series of emails sent to prospects on a predetermined schedule. Each message in the sequence is designed to build on the previous one, gradually educating the recipient, addressing objections, and moving them closer to a desired action whether that is booking a demo, signing up for a trial, or making a purchase. Drip campaigns are a staple of both marketing automation and sales outreach strategies.

In B2B sales, drip campaigns are particularly effective for cold outreach. A well-designed sequence might start with a personalized introduction, follow up with a case study or social proof, and conclude with a direct call to action. The spacing between emails typically two to five days keeps the sender top of mind without overwhelming the recipient.

The key to successful drip campaigns is relevance. Each email should provide genuine value and feel like a natural continuation of the conversation. Generic, template-heavy sequences get ignored. The best-performing drip campaigns combine personalization, strong copywriting, and strategic timing to create a sequence that feels intentional rather than automated.
