Campaigns vs Workflows: When to Use Each One
A clear breakdown of when to use one-off campaigns versus automated workflows, and how experienced people use both together.
This question comes up constantly and most people end up using one when they should be using both.
They send campaigns when a workflow would perform better, and build workflows for things that only needed a one-time send. The result is usually the same: more work, lower engagement, and a system that feels harder than it should.
A real example
Say you launch a new feature.
If you only use a campaign:
- existing users hear about it
- new users who sign up next week never see it
If you only use a workflow:
- new users learn about it
- your current users miss the announcement entirely
The right setup:
- campaign → announce to your current audience
- workflow → add it as a step in onboarding for future users
That combination is what most teams miss.
Campaigns are one-time sends. You write an email, pick an audience, and send it at a specific moment.
Workflows are automated sequences. You build a multi-step flow once, and it runs continuously for every contact who enters it.
That's the mechanical difference. The strategic difference is about timing.
Use campaigns when the moment matters
Campaigns are the right choice when you're sending something tied to a specific point in time:
- Product announcements
- Seasonal promotions
- Event invitations
- Monthly newsletters
- Flash sales or limited offers
- Company news
The content is relevant now and won't be relevant in the same way next month. You want everyone in the audience to receive it around the same time.
Use workflows when the trigger matters
Workflows are the right choice when the timing depends on the individual contact, not the calendar:
- Welcome sequences after signup
- Trial nurture after starting a free trial
- Post-purchase onboarding
- Re-engagement after 30 days of inactivity
- Lead scoring follow-up when a threshold is reached
Each contact enters the workflow at a different time, and the sequence is the same for everyone who enters — but personalized to their moment.
The overlap zone
Some teams get stuck because certain use cases could go either way. A "new feature announcement" could be a campaign to existing users and a workflow step for new users who sign up after the feature launches.
The rule of thumb: if you're going to send it once and move on, it's a campaign. If you're going to need this content to be delivered automatically to future contacts, build it into a workflow.
Use both together
A common pattern: send a campaign to announce a new feature to your existing list, then add a "new feature highlight" step to your onboarding workflow so future signups learn about it too. Campaign handles the broadcast. Workflow handles the ongoing automation.
A practical planning framework
When deciding between a campaign and a workflow, ask:
- Is this time-sensitive? → Campaign
- Will future contacts need this? → Workflow
- Is the audience everyone, or a triggered subset? → Everyone = campaign, triggered subset = workflow
- Will I send this once or repeatedly? → Once = campaign, repeatedly = workflow
Most people don’t have a campaigns problem or a workflows problem, they have a coordination problem.
Once you start thinking in terms of:
- what needs to happen once
- what needs to happen continuously
the system gets simpler.
Campaigns handle moments.
Workflows handle journeys.
You need both, just not for the same job.
