What it means
A drip campaign is the simplest unit of marketing automation: a pre-written series of messages, sent on a schedule, kicked off by a triggering event. The classic trigger is a list opt-in ("subscribe to get our weekly tips"), but drips can be triggered by anything: a signup, a feature use, a stalled deal, an abandoned cart, a churn event.
The name comes from "drip irrigation": small, regular doses instead of a single deluge. The point of a drip is that nobody converts on first contact, so the next-best thing is to be present in the prospect's inbox or DMs once every few days with something useful, until they are ready to act.
Drips can run on email, DMs, push notifications, in-app messages, SMS, or any combination. The trigger-and-step logic is the same. What changes is the cadence (DMs faster, email slower), the consent model (each channel has its own opt-in), and the content length (DMs short, email long).
The four standard drip structures
Most successful programmes run four core drips, each with a different goal:
- Welcome. Fires the moment a contact opts in. Delivers what was promised, sets expectations for the relationship, and introduces the product without selling hard. Typically 4-6 messages over 7-14 days.
- Nurture. Runs after the welcome ends. Long-form, low-cadence content that builds trust and keeps you top of mind until purchase intent shows up. Weekly is the sweet spot; biweekly is the floor.
- Re-engagement. Wakes up contacts who have gone quiet. The goal is not to sell; it is to find out whether they are still on the list voluntarily. Successful re-engagement either gets a click or unsubscribes the contact; both outcomes are wins.
- Win-back. For churned customers. Different from re-engagement because the contact has previously paid you. Often the most effective drip in a B2B portfolio when sequenced correctly, but the easiest to misfire if it feels desperate.
Cadence rules
Three principles to anchor your cadence design:
- Open with daily, fade to weekly. The first three or four messages can fire on consecutive days while the contact is still warm. After day 7, drop to once every 3-5 days. After day 30, weekly.
- Never send two channels on the same day. An email and a Telegram DM landing within four hours of each other reads as desperate. Stagger by at least 24 hours.
- Respect time zones. Send during the contact's local business hours, not yours. The fastest way to a low open rate is mid-morning emails delivered at 4 AM in their time zone.
A/B testing each step
Drips are uniquely good for A/B testing because every step is a ready-made experiment: same audience, same trigger, same channel with just two subject lines or two opening paragraphs. A few rules we follow:
- One variable per test. Subject line OR opening line OR CTA placement; never all three. You will not be able to attribute the lift.
- Test the first step first. The opening message accounts for ~40% of the entire drip's downstream conversion. That is where the biggest lifts live.
- Stop at 95% confidence or 1,000 sends per arm, whichever comes first. Drips do not get the volume of a broadcast; be willing to call a winner at 80% confidence on huge effects and at 95% on small ones.
- Keep a holdout. Always reserve 5% of contacts as a no-message control. Without it you cannot prove the drip outperforms doing nothing.
Why it matters
Drips work because conversion is rarely a single moment; it is a series of small commitments. A well-designed drip stays present during the period when a prospect is forming an opinion, without requiring a salesperson to remember to send each follow-up.
For most teams the math is simple: a single sales rep can send maybe 50 follow-ups a day. A drip can send 500,000 at the right time, with the right context, to the right person. The personalisation does not need to be smart; it needs to be present.
Real-world examples
- SaaS welcome drip. Day 0: thanks-and-quickstart email. Day 1: a 60-second product video. Day 3: a customer case study. Day 6: an invitation to book a setup call. Day 9: "We noticed you haven't connected your first integration. Can we help?"
- Ecommerce post-purchase drip. Day 0: order-confirmation transactional. Day 3: "How to use it" video. Day 14: review request. Day 30: cross-sell to complementary product. Day 60: loyalty program invite.
- Real-estate buyer drip. Week 1: "What to look for in a first-home" guide. Week 2: mortgage-calculator walkthrough. Week 3: neighborhood market reports. Week 4: "Schedule a viewing" CTA.
- Cold-outreach nurture. Lead replies "not now" to a DM. They move into a 90-day nurture: month 1 sends industry insights, month 2 sends a case study, month 3 sends a soft re-engagement asking if circumstances have changed.
- Course-creator launch drip. 7 days before launch: behind-the-scenes content. 3 days: testimonials. 1 day: launch reminder. Launch day: cart open. Final day: cart closing in 4 hours.
Common mistakes
- No exit triggers. A drip that keeps emailing someone after they replied "I'm not interested" is the fastest way to make every drip you run feel worse.
- Cadence too fast. Two messages a day for a week looks like a glitch, not a sequence. Open rates collapse after step 3.
- Every step asks for the demo. If every email ends with "book a call", the drip feels like a sales push with extra steps. Mix in education, social proof, and question prompts.
- Same content on every channel. A 600-word email does not translate to a Telegram DM. Tailor message length to channel.
- No holdout group. Without a no-message control you cannot tell whether the drip caused the conversion or the prospect would have converted anyway.

How CRM Solid handles it
CRM Solid's Automation Sequences engine is built for drips that run across email, Telegram, X DMs and Instagram. Each step has its own channel, delay, exit triggers, and A/B variant slots. Spintax keeps every send unique, account rotation respects per-channel rate limits, and stop-on-reply is on by default, so a contact who replies on any channel exits the drip automatically. Holdout groups are built-in so you can prove attribution.
