Updated September 2026. Email platforms have cut their free plans sharply this year — confirm current limits on each provider’s pricing page.
An email automation workflow sends the right email when a subscriber does something — joins your list, buys, or goes quiet — without you pressing send. You set it up once. This guide covers the five workflows worth building first, how to plan them on paper, and an honest look at which email tools still let you automate for free.
How an automation workflow works
Every workflow has the same three parts:
- A trigger — the event that starts it, such as “subscribed to my list” or “made a purchase”.
- Delays — how long to wait before each email.
- Emails and conditions — what to send, and optionally a rule such as “only if they haven’t bought yet”.
Once you understand those three parts, every email tool’s automation builder looks familiar.
Plan it on paper first
Before opening any software, write each workflow down in one line per email:
| When | Goal | One call to action | |
|---|---|---|---|
| 1 | Immediately after signup | Deliver what they signed up for | Download the free guide |
| 2 | 2 days later | Show your most useful content | Read your best article |
| 3 | 5 days later | Explain what you offer | See your product or service |
Giving each email a single goal and a single call to action keeps the sequence short and easy to measure. If you can’t state an email’s goal in a few words, leave it out.
The five workflows worth building first
1. Welcome series
Trigger: someone joins your list. This is the workflow almost every business should build first, because new subscribers are paying the most attention right after signing up. Deliver what you promised in the first email, then introduce your best content and what you offer over the next few emails.
2. Post-purchase follow-up
Trigger: a purchase. Help the customer get value from what they bought — setup instructions, tips, answers to common questions — then ask for a review once they’ve had time to use it. This workflow needs your email tool connected to your shop or payment system so it knows a purchase happened.
3. Abandoned cart
Trigger: a shopper adds items to a cart and leaves without buying. Send a simple reminder, then optionally a second one. This only works if you run an online shop that’s connected to your email tool, and on many platforms it’s a paid feature. Avoid training customers to wait for a discount: offer one sparingly, if at all.
4. Re-engagement (win-back)
Trigger: a subscriber hasn’t opened or clicked for a set period. Ask whether they still want your emails and make leaving easy. Removing people who never engage keeps your list healthy and helps your emails reach inboxes.
5. Lead nurture
Trigger: someone downloads a lead magnet but hasn’t bought. Send a short run of genuinely useful emails that answer the questions people ask before buying. For a deeper walkthrough, see email automation sequences for lead nurturing.
Which email tools still let you automate for free?
This changed a lot in 2026. Several popular providers reduced their free plans, and some removed automation from them entirely. At the time of writing:
| Tool | Free plan and automation | Worth knowing |
|---|---|---|
| Mailchimp | Free plan has a small contact limit and only a preview of automation flows | Working multi-step automations start on the Standard plan |
| MailerLite | Free plan includes a small number of active automations | Its free subscriber and send limits were reduced in 2026 |
| Brevo | Free plan includes automation, with a cap on contacts in automations | Free sending is limited per day, not per month |
Free plans are fine for building and testing your first welcome series. Expect to pay once your list grows or you need more than one or two workflows. Compare total cost at your expected list size, not just the free tier.
Setting up your first workflow
The buttons differ between tools, but the steps are the same:
- Connect your signup form to the list or audience the workflow will watch.
- Create a new automation and choose the trigger, for example “subscriber joins”.
- Add your first email with no delay, and write it from your paper plan.
- Add a delay, then the next email. Repeat for the rest of the sequence.
- Test it by signing up yourself with a separate email address. Check every email arrives, looks right on a phone, and every link works.
- Turn it on.
How to tell if it’s working
- Click rate — are people clicking the one link you asked them to? This is more reliable than open rate.
- Conversions — did they do what the email was for, such as reading the article or buying?
- Unsubscribes — a spike after one particular email tells you that email is the problem.
A note on open rates: privacy features in some email apps load images automatically, which can count as an “open” even if the person never read the email. Use opens as a rough signal only, and judge workflows mainly by clicks and conversions.
Common mistakes
- Building five workflows at once. Start with a welcome series, measure it, then add the next.
- Setting and forgetting. Review your workflows every few months — links break, offers expire and products change.
- Sending too often. A new subscriber getting an email every day for two weeks will unsubscribe.
- Skipping consent. Only email people who signed up, and include a clear unsubscribe link in every email.
Frequently asked questions
What is the easiest email workflow to start with?
A welcome series. It’s triggered by a signup, needs no shop integration, and reaches people when they’re most interested.
Can I automate emails for free?
Some providers still include limited automation on their free plans, but several reduced or removed it in 2026. Free plans suit a small list and one or two workflows; plan to upgrade as you grow.
How many emails should a welcome series have?
Three to five is a sensible starting point. Short sequences are easier to write, test and improve. Add emails only when you have something genuinely useful to say.
Do I need a website to use email automation?
You need a way for people to sign up. Most email tools provide a hosted signup page, so you can start without your own site.
