Most guides on email drip campaigns start with a calendar: “send email 1 on day 1, email 2 on day 3.” That’s backwards. A good drip campaign doesn’t run on a schedule, it runs on behavior. The email someone gets should depend entirely on what they just did, not what day it happens to be.
I run this blog’s list on MailerLite, and building drip sequences this way, trigger first, timing second, is the single biggest shift that made mine actually work. Here’s how to think about it, with real examples of what each sequence should actually say.
Forget the schedule, think in triggers
An email drip campaign is a pre-written sequence that sends automatically, but the thing that starts it is what matters most. Four actions cover almost every situation you’ll actually need to automate: someone subscribes, someone downloads a specific lead magnet, someone clicks a specific link, or someone goes quiet. Each one calls for a different sequence, with a different job to do.
Trying to build one giant “everyone gets this” sequence is where most beginners go wrong. It ends up either too generic to be useful, or so overloaded with branches it never gets finished. Build one sequence per trigger instead, and each one stays simple enough to actually ship.
Here’s the practical difference. A scheduled approach sends the same “week 2 email” to someone who joined yesterday and someone who joined three months ago, regardless of what either of them actually needs right now. A trigger-based approach sends the right email to the right person at the moment it’s relevant to them, whether that’s five minutes after signup or five months later when they finally click a specific link. The setup takes a bit more thought upfront. The payoff is emails that feel considered instead of generic.
Trigger 1: someone subscribes (the welcome sequence)
The highest-interest moment you’ll ever have with a subscriber is the five minutes after they sign up. A welcome sequence is what stops that interest from evaporating into inbox silence.
Keep it to three or four emails over the first week: deliver whatever you promised immediately, point them to your best content on day two, teach them something useful on day three or four, and close by asking a question, replies are gold for both trust and deliverability. If you want the fuller breakdown of this specific sequence, I’ve written a whole guide on it, see the Recommended Reading below.
What this actually looks like: say someone downloads a generic “start your side hustle” checklist. Email 1 delivers the checklist and introduces you in two sentences, no life story. Email 2, sent the next day, links to your single most-shared post, the one that best represents what your blog is about. Email 3, a few days later, teaches one specific, actionable tip that isn’t in the checklist, proof there’s more value where that came from. Email 4 asks a simple question: “what’s the one thing holding you back from starting?” The replies to that single question will teach you more about your audience than any survey.
Trigger 2: someone downloads a specific lead magnet
This one’s easy to skip, but it’s one of the highest-converting sequences you can build. If someone downloaded your “freelance pricing calculator,” they’ve told you exactly what they’re struggling with. Treat that like the gift it is.
Build a short two-to-three email sequence specific to that lead magnet’s topic, not your generic welcome series. Someone who downloaded a pricing guide wants more on pricing, not a broad “welcome to my blog” tour they may have already gotten from your main welcome sequence. If you run multiple lead magnets, this means multiple small sequences, more setup work upfront, but far better relevance than one email trying to serve everyone.
Worked example: someone grabs your “freelance pricing calculator.” Email 1 (immediate) delivers it and highlights the one number most people get wrong. Email 2 (two days later) covers a related question the calculator doesn’t answer, like when to raise rates with an existing client. That’s it, two emails, both narrowly about pricing. Nothing generic gets mixed in.
Trigger 3: someone clicks a specific link
A click is a stronger signal than an open. Someone who clicks through to a specific product or article is telling you where their actual interest sits, right now, not just that they glanced at a subject line.
Most email platforms let you build an automation rule around a specific link click: if someone clicks the link to your pricing guide, tag them and send a short follow-up sequence about pricing over the next few days. This is where email marketing stops being “blast the same thing to everyone” and starts feeling personal, because it’s actually responding to what that person just did.
How this differs from Trigger 2: the lead magnet sequence fires the moment someone opts in, based on what they explicitly asked for. This one fires later, based on what they’re clicking inside your regular content or newsletter, a much softer, more passive signal. Both are useful, and they can even overlap for the same person, someone might get the lead magnet sequence after opting in, then later trigger the click-based sequence when they click through from an unrelated newsletter. That’s fine. Just make sure the content in each doesn’t repeat itself word for word.
Trigger 4: someone goes quiet (the win-back sequence)
Every list has subscribers who signed up enthusiastically and then went silent, no opens, no clicks, for months. Rather than ignoring them (which quietly hurts your sender reputation) or purging them immediately, a short win-back sequence gives them one honest last chance.
Two emails is usually enough: a genuine “still want to hear from me?” check-in, then a final “I’ll remove inactive subscribers soon, click here to stay” notice. Anyone who doesn’t respond to either, you can comfortably remove. This isn’t about being harsh, it’s that a smaller, engaged list consistently outperforms a bloated, unopened one, both for your open rates and for your platform’s deliverability standing.
Set the trigger around 60 to 90 days of no opens or clicks, tight enough to catch genuine disengagement, loose enough that you’re not chasing someone who just had a busy month. Most email platforms let you build this as a simple inactivity filter rather than something you have to track manually.
How to actually build one in MailerLite
Here’s the exact workflow I use for my own list on MailerLite, which is one of the easiest platforms to build these on, its automation editor is included on the free plan up to 250 subscribers, no upgrade required to start.
- Go to Automations and choose your trigger. MailerLite lets you start from a group join, a specific form submission, or a link click, matching the four triggers above directly.
- Add your emails with delays between them. Drag in each email, then set the wait time before the next one sends, immediately, one day later, three days later, whatever fits the sequence.
- Write each email to do one job. Deliver something, teach something, recommend something, ask something. If an email is trying to do three of those at once, split it into two emails instead.
- Turn it on, then actually check back. Once a month, glance at open and click rates for each automation. A sequence that looked great on paper sometimes needs a rewrite once real data comes in.
Worth being upfront here since I’ve corrected this elsewhere on the blog: I’m gradually moving my own list toward Kit (ConvertKit) for its stronger automation branching once I’ve outgrown MailerLite’s current setup, but MailerLite is what I run today, and it’s a solid, free place for you to build your first drip sequences too. One thing worth knowing if you’re comparing the two: Kit’s free plan covers newsletters up to 10,000 subscribers and includes one basic automation, but multi-step sequences like the ones in this guide need a paid plan, whereas MailerLite includes full automation free from the start. That’s a real practical difference if you’re picking a platform specifically to build drip campaigns on a budget.
How to tell if a sequence is actually working
Turning on an automation and never checking it again is almost as common a mistake as never building one at all. Three numbers are worth watching for each sequence:
- Open rate. If it drops sharply between email 1 and email 2 of the same sequence, your subject lines or the gap between sends probably need work.
- Click rate. A low click rate with a healthy open rate usually means the content is fine but the call to action is weak or buried.
- Unsubscribe rate on a specific email. If one particular email in a sequence consistently drives more unsubscribes than the others, that’s your clearest, most specific signal to rewrite it.
For a sense of what’s normal, Mailchimp’s current email marketing benchmarks break down typical open and click rates, useful context so you’re comparing your automation against realistic numbers rather than guessing whether a given open rate is good or bad.
Common drip campaign mistakes
- Building one giant sequence for everyone. Different triggers need different content. A single one-size-fits-all sequence ends up too generic to convert anyone well.
- Never revisiting it after launch. A drip sequence isn’t “set and forget” in the sense of never checking on it, it’s set and forget the manual sending, not the improving. Check the numbers periodically.
- Selling too early or too hard. If every email in a sequence is a pitch, people unsubscribe fast. Teach and help far more often than you sell.
- Ignoring your unsubscribe and complaint rate. A spike after a specific email tells you something in that sequence isn’t landing. Don’t ignore that signal.
- Letting sequences overlap awkwardly. If someone can trigger both your welcome sequence and a lead-magnet sequence within the same week, check that the two don’t repeat the same points or feel like two strangers emailing the same person. A quick skim through both, back to back, catches this fast.
FAQ
What’s the difference between a drip campaign and a newsletter?
A newsletter goes to your whole list on a schedule, same content, same day, for everyone. A drip campaign is triggered by an individual action and sent only to the person who took it, on a timeline relative to that action, not a calendar date.
How many emails should a drip campaign have?
For most triggers, three to five emails is plenty. A welcome sequence works well at three to four; a win-back sequence often needs just two. Longer isn’t automatically better, each email should have a clear job, and once the job’s done, the sequence should end.
Can I set up drip campaigns for free?
Yes. MailerLite includes full automation on its free plan up to 250 subscribers, so you can build and run everything covered in this guide without paying anything to start.
Should every trigger get its own sequence?
Not necessarily all four at once. Start with the welcome sequence, since it has the highest impact for the least setup effort, then add the others as you have time. A single well-built welcome sequence beats four half-finished ones.
Should drip emails feel personal, or is it obvious they’re automated?
Aim for personal. Write each email as if you’re speaking to one specific person who just took the action that triggered it, not a broadcast to a list. Merge tags for a first name help, but tone matters more than any personalization token, write like you would to a single reader, not a crowd.

Build the one you’re missing
Most blogs have zero automation running, which means every ounce of nurturing happens manually or not at all. Even one well-built sequence, just the welcome one, changes that completely, and it keeps working while you’re doing literally anything else.
Pick the trigger that matches where you’re weakest right now, build that one sequence this week, and add the rest over time. That’s how mine got built too, one at a time, not all at once.
