Drip Campaign: Definition, Examples, and Best Practices

A drip campaign is a series of pre-written messages sent automatically on a fixed schedule after a trigger, such as a signup or a purchase. The term comes from drip irrigation, where small amounts of water are delivered steadily over time rather than all at once. Most drip campaigns run over email, though the same structure applies to SMS, push, and in-app messages.

Why Drip Campaigns Work

Timing beats volume. A drip campaign reaches someone while their interest is still active, instead of waiting for the next monthly newsletter that may land three weeks after they cared.

Repetition without nagging is the second reason. One email gets missed. A five-email sequence spaced four days apart gets seen, and each message can approach the same offer from a different angle.

Drip campaigns are also written once and run indefinitely. A welcome sequence built in an afternoon greets every new subscriber for the next two years, which makes it one of the highest-leverage assets in an email program.

How a Drip Campaign Works

A drip campaign has four moving parts:

Entry trigger. The event that adds someone to the sequence: a form submission, a free trial signup, a first purchase, or a tag applied in the CRM.
Message sequence. The pre-written emails in fixed order. Each has its own subject line, body, and single call to action.
Delays. The wait time between messages, usually 1 to 7 days. The gap can also be conditional, such as sending the next email only on a weekday.
Exit criteria. The rule that removes someone from the sequence, normally the conversion the campaign is driving. Without exit criteria, buyers keep getting sold what they already own.

Some platforms add branching, so a subscriber who clicked the pricing link gets a different email four than one who did not. That branching is where a drip campaign starts to blur into full marketing automation.

Types of Drip Campaigns

Welcome drip. Introduces the brand over 3 to 5 emails after signup. Sets expectations for frequency and content.
Onboarding drip. Walks a new user through setup steps, timed to the actions they have not completed yet.
Lead nurture drip. Sends educational content to a lead who is not sales-ready, spaced over weeks rather than days.
Abandoned cart drip. Recovers an incomplete checkout with 2 to 3 messages inside 72 hours.
Re-engagement drip. Targets subscribers who have not opened in 90 to 120 days, then suppresses those who still do not respond.
Post-purchase drip. Covers delivery, product usage, a review request, and a replenishment reminder.
Renewal drip. Fires ahead of a subscription renewal date, typically at 30, 14, and 3 days out.

Drip Campaign Examples

Email drip campaign for a SaaS free trial (14 days):

Day 0: Account confirmation and the single first step to take.
Day 1: How to complete setup, with a 3 minute walkthrough.
Day 4: One customer result, tied to the feature most trials skip.
Day 8: Comparison against the manual process the tool replaces.
Day 12: Trial ending, with pricing and a booking link.
Day 14: Trial expired, plus a one-week extension offer.

Ecommerce welcome drip:

Immediately: The promised discount code, nothing else.
Day 2: The brand story and what makes the product different.
Day 5: Bestsellers, with reviews.
Day 9: Discount code expiry reminder.

B2B lead nurture drip after a whitepaper download:

Day 0: The download link.
Day 3: A related case study in the same industry.
Day 10: A benchmark or data point relevant to the reader’s role.
Day 17: An invitation to a demo or consultation.

Note the pattern in all three. The gaps widen as the sequence goes on, and each email carries one call to action, not four.

Drip Campaign vs Nurture Campaign vs Broadcast Email

A broadcast email goes to a whole list at one moment, chosen by the sender. Everyone receives it on the same day regardless of when they subscribed. Newsletters and sale announcements are broadcasts.

A drip campaign starts from each person’s own trigger date. Someone who signs up today gets email one today. Someone who signed up last month is already on email four.

A nurture campaign is a drip campaign with a specific job: moving a lead toward sales readiness. Every nurture campaign is a drip campaign, but a post-purchase or re-engagement drip is not nurture. In practice most platforms use the terms interchangeably.

How to Track a Drip Campaign

Track performance at the step level, not just the sequence level. Platform reports give opens and clicks per email, which shows exactly where subscribers stop engaging.

Tag every link with UTM parameters so analytics can attribute revenue back to the specific email. Set utm_content to the step number, since that is what makes step-by-step comparison possible:

Without that tagging, the whole sequence collapses into one line in Google Analytics 4, and you cannot tell which email drove the purchase.

Watch three numbers: click-through rate per step, the drop-off point where engagement falls sharply, and unsubscribe rate per email. Anything above 0.5% unsubscribes on a single send signals the message or the cadence is wrong.

Frequently Asked Questions

What is a drip campaign in simple terms?

A drip campaign is a set of emails written in advance and sent automatically over days or weeks after someone takes an action. Signing up for a newsletter and then receiving a welcome email, followed by two more over the next week, is a drip campaign. The sender writes it once, and it runs for every new person from then on.

How many emails should a drip campaign have?

Three to seven emails covers most sequences. Welcome and abandoned cart drips work well at 3 to 4. B2B lead nurture drips run longer, often 5 to 7 spread across several weeks. Add emails only when each one has a distinct point to make.

What is the difference between a drip campaign and marketing automation?

A drip campaign is one workflow type. Marketing automation is the software category that runs it, alongside lead scoring, segmentation, CRM updates, and ad audience syncs. Every automation platform can run drip campaigns, but drip campaigns are only a fraction of what those platforms do.

Are drip campaigns still effective?

Yes, provided the sequence is triggered by a real signal and offers something useful at each step. Drip campaigns fail when they are generic, too frequent, or missing exit criteria. The CAN-SPAM Act also requires a working unsubscribe link in every commercial email, and opt-out requests must be honored within 10 business days.
