How to Set Up an Email Drip Campaign (Step by Step)
A working guide to building a drip campaign: choosing the trigger, mapping the sequence, writing emails people finish, setting exit conditions, and knowing which numbers mean it is working.
Most drip campaigns fail for an unglamorous reason: they were written as a set of emails rather than designed as a path from one state to another. The emails are fine in isolation and the sequence goes nowhere.
This guide is the build order. Eight steps, a worked example with real timing, the numbers worth watching, and the mistakes that quietly cost the most.
What a drip campaign actually is
A drip campaign is a fixed series of emails delivered automatically, timed relative to **each recipient's own trigger date** rather than to a calendar date. Someone who signs up today and someone who signed up in March both get email one on their personal day zero.
That per-person timing is the whole advantage. It means the sequence can be genuinely relevant to a moment (just subscribed, just abandoned a cart, just finished a trial) in a way a broadcast never can, and it means you write it once and it keeps working.
It is worth separating three things people use interchangeably:
- **Drip campaign:** fixed sequence, fixed order, triggered per person. Predictable and easy to reason about.
- **Nurture campaign:** usually a drip campaign whose specific goal is warming a lead who is not ready to buy.
- **Behavioural or lifecycle automation:** branching logic that reacts to what someone does mid-sequence. More powerful, considerably harder to maintain.
Start with a drip campaign. Add branching only when you have evidence about where people fall off.
Step 1: Name the trigger and the single outcome
Two sentences, written down before you draft anything:
> **Trigger:** what has just happened to this person.
> **Outcome:** the one specific action this sequence exists to produce.
Examples that are specific enough to build:
- Trigger: downloaded the pricing calculator. Outcome: books a 20-minute call.
- Trigger: started a free trial. Outcome: publishes their first project.
- Trigger: added to cart, did not check out within 4 hours. Outcome: completes the order.
- Trigger: became a customer. Outcome: reaches the activation moment within 14 days.
- Trigger: went cold for 90 days. Outcome: replies, or unsubscribes cleanly.
If you cannot write the outcome as a single observable action, you are not ready to write emails. "Nurture the lead" and "stay top of mind" are not outcomes; they are how sequences end up with no measurable result and no reason to be improved.
Step 2: Work out what stands between the two
This is the step that separates sequences that convert from sequences that just arrive. Ask: **why has this person not already done the outcome?**
Write the honest list. Usually it is three to five items:
- They do not believe it will work for their situation
- They do not know it does the specific thing they need
- They think it costs more than it does
- They tried something similar before and it failed
- They agree it is a good idea and it is not this quarter's priority
- They are not the person who can approve it
**Each email in your sequence handles one of these.** That is the design. Not "email 3 is a case study" but "email 3 handles the belief that this does not work for a team our size, and it uses a case study to do it".
The fastest source for this list is sales calls, support tickets, and the replies you already get. Do not invent it.
Step 3: Choose length and cadence
One objection per email gives you your length. Four to seven emails covers most sequences.
Cadence should be front-loaded, because attention decays fastest right after the trigger:
| Email | Day | Job |
|---|---|---|
| 1 | 0 (within minutes) | Deliver what was promised, set expectations |
| 2 | 2 | Handle the biggest objection |
| 3 | 5 | Proof: a specific result, named |
| 4 | 9 | Handle the second objection, usually price or effort |
| 5 | 16 | Direct, clear ask |
| 6 | 30 | Useful thing with a soft ask, then exit to your regular list |
Two rules that matter more than the exact spacing:
- **Email one goes out immediately.** Not in an hour. The person is on your site right now, and a delayed first email arrives to someone who has moved on.
- **Do not send on the recipient's timezone midnight or on Saturday morning** unless you have data saying otherwise. Send-time optimisation is a small effect; sending at an obviously wrong hour is a large one.
Step 4: Write emails people finish
The practical constraints:
- **One idea per email.** If email two also mentions the integration, the pricing, and the webinar, it handles nothing.
- **One call to action, repeated.** Two different asks halve both.
- **Subject lines that describe rather than tease.** Curiosity gaps get opened once and trust you less afterward. "The three-day setup, start to finish" beats "You won't believe this".
- **Short.** 120 to 200 words for most emails in a nurture sequence. If it needs more, the extra belongs on a page you link to.
- **Plain formatting.** A text-forward email from a person outperforms a designed template in almost every sequence of this type, because it matches what the inbox expects from one-to-one mail.
- **From a person, not the brand.** Real name, real reply-to address, and someone actually reads replies.
- **Every email works alone.** People do not read your sequence in order. Assume any email might be the first one they open.
Skip the personalisation that is not personalisation. A first name in the subject line is transparently automated now. Referencing the specific thing they downloaded is not.
Step 5: A worked example
Trigger: downloaded a website planning checklist. Outcome: starts building a site.
**Email 1, day 0, sent immediately**
Subject: Your website planning checklist
Delivers the file with no preamble. One line on what to do with it first. One line setting expectations: "I'll send you four short notes over the next two weeks on the parts people get stuck on. Reply any time and it reaches me."
**Email 2, day 2**
Subject: The part everyone skips
Handles the biggest objection, which here is not price but paralysis. Makes the case that the structure decision comes before the design decision, and points at [the seven types of business website](/blog/types-of-business-websites) so they can pick one and move.
**Email 3, day 5**
Subject: How Maria launched in a weekend
One specific customer, named, with the actual timeline and the actual outcome. Proof that is checkable, not a testimonial adjective.
**Email 4, day 9**
Subject: What this costs, honestly
Handles the money and effort objection directly. Real numbers, including what it costs if they do nothing. No discount.
**Email 5, day 16**
Subject: Want me to look at your plan?
The direct ask, with a booking link and a genuinely low-commitment framing.
**Email 6, day 30**
Subject: Three site structures that convert
Useful on its own, soft ask at the end, then the person moves to the regular list and out of the sequence.
Five of the six earn their place by being useful whether or not the reader buys. That ratio is roughly right.
Step 6: Set exit conditions before you turn it on
This is the step most often skipped, and it is the one that causes the embarrassing failures. Someone must leave the sequence when:
- **They complete the outcome.** Nothing erodes trust faster than being asked to start a trial you started yesterday.
- **They buy.** Applies to every parallel sequence, not only this one.
- **They reply, or a salesperson engages.** A human conversation always outranks an automation.
- **They enter a higher-priority sequence.** Decide the precedence order in advance and enforce it, so nobody receives three sequences at once.
- **They have not opened four in a row.** Continuing to send to someone who never opens damages deliverability for everyone else on your list.
- **They unsubscribe.** Obviously, and it must be one click, visible, and instant.
Write these as rules in the tool, then test each one by pushing a real record through it.
Step 7: Set it up and test it properly
Any mainstream email platform can do this, and the choice matters far less than the design. What you actually need:
- Triggers based on site or product events, not only on list membership
- Per-person delays, not calendar sends
- Exit and suppression rules
- Reporting per email, not only per campaign
- Authentication configured: SPF, DKIM, and DMARC on your sending domain
The last one is not optional. Since the major mailbox providers tightened bulk-sender requirements, an unauthenticated domain gets filtered regardless of content quality. Set it up once, verify it, and re-verify after any DNS change.
Then test like it is going to production, because it is:
1. Push yourself through the real trigger, on the real site, not with a manual add.
2. Check that email one arrives within minutes.
3. Check every link, including the unsubscribe.
4. Read all six on a phone. Most will be read there.
5. Trigger each exit condition and confirm the sequence actually stops.
6. Check what your emails look like with images blocked.
7. Send one to a Gmail, an Outlook, and an Apple Mail address and look at all three.
Step 8: Measure the thing you designed for
Per email, watch:
- **Delivery rate.** Below 98% means a deliverability problem, and nothing else you measure is meaningful until it is fixed.
- **Open rate.** Useful for comparing subject lines within your own sequence. Note that privacy features on some mail clients inflate opens, so treat the absolute number with suspicion and the relative trend as real.
- **Click rate.** The honest engagement signal.
- **Reply rate.** Underrated. A sequence that produces replies is producing relationships.
- **Unsubscribe rate.** Above roughly 0.5% on a single email means that email is wrong for that audience.
Across the sequence, watch two things:
- **Conversion to the outcome.** The only number that decides whether the sequence works.
- **Where people stop.** A cliff between emails three and four tells you exactly which email to rewrite.
Give it enough volume to mean something before you change anything. A few hundred people through a sequence is a signal; twenty is noise.
The mistakes that cost the most
- **No exit conditions.** Covered above, and worth repeating because it is the most common and the most damaging.
- **Writing for yourself instead of the objection.** Every email should be traceable to a real thing a real person said.
- **Selling in email one.** Email one delivers the thing you promised. That is all it does.
- **Sending to a purchased list.** It will not convert, and it will burn your sending domain for the list that would have.
- **Never revisiting it.** A sequence written eighteen months ago references a product you have changed. Re-read every sequence quarterly.
- **Sending traffic to a page that does not match the email.** A drip campaign is only as good as the destination. If the email promises a specific outcome and the landing page talks about something else, the sequence gets blamed for a page problem.
Key takeaways
A drip campaign is a design problem before it is a writing problem. Name the trigger, name the one outcome, list the real objections between them, give each objection one short email, front-load the timing, and build the exit rules before you turn it on.
Then look at where people stop and fix that email. That single loop, run four times, will beat any amount of upfront polish.
The destination matters as much as the sequence: every email points at a page, and that page has to deliver on what the email promised. If yours does not, [building a landing page that matches the sequence](/guides/how-to-create-a-landing-page) is the higher-leverage fix.
