Every day, leads come in through your website, social media, or network. Some are ready to buy. Most aren't — not yet. They need information, trust, a few touchpoints before they make a decision. The problem: maintaining those touchpoints manually costs hours every week and is the first thing to get dropped when things get busy.
Email automation solves that. You build a sequence of emails that are sent automatically at the right moments, personalised based on what the recipient has done or requested. No manual work, no forgotten follow-ups, no leads falling through the cracks. In this article, you'll learn which email sequences you need, which tools fit SMBs best, and how to get started.
What Is Email Automation?
Email automation means emails are sent automatically based on triggers — actions a lead or customer takes. Someone fills in a form: trigger. Someone opens an email but doesn't click: trigger. Someone hasn't ordered in 30 days: trigger. Even receiving a document as an email attachment can be a trigger — read how AI document processing makes that possible.
The distinction from a newsletter is crucial. A newsletter is a broadcast: the same email to everyone at the same time. Email automation is personal: the right email to the right person at the right moment, based on their behaviour.
The impact is measurable. According to Omnisend, automated emails generate 29% of all email revenue while accounting for just 2% of total email volume. They're more effective because they're relevant and timely.
The Five Email Sequences Every Business Needs
1. Welcome Sequence (3–5 emails)
The welcome sequence starts when someone subscribes to your newsletter, fills in a form, or downloads a free resource. This is your chance to make a first impression and set expectations.
Example welcome sequence:
- Email 1 (immediate): Thanks for signing up. Here's [the resource you requested]. Brief introduction: who we are, what we do.
- Email 2 (day 2): Our most-read article or case study — something that delivers immediate value.
- Email 3 (day 5): Background story: why we do what we do, what makes us different.
- Email 4 (day 8): Concrete results: what do our solutions deliver? Numbers, examples.
- Email 5 (day 12): Soft CTA: "Want to know what we can do for your business? Schedule a free consultation."
Welcome sequence open rates are typically 50–80% higher than regular emails. It's the moment when the recipient is most engaged. Use it.
2. Lead Nurture Sequence (5–8 emails)
Not every lead is ready to buy. The nurture sequence guides them from interest to purchase readiness by providing valuable information — not by pushing.
Structure:
- First three emails: educational. Share knowledge, insights, tips that are immediately useful.
- Emails four and five: social proof. Case studies, client results, testimonials.
- Emails six and seven: positioning. How your approach works, what differentiates it from alternatives.
- Final email: direct CTA. "Ready to take the next step?"
Timing depends on your sales cycle. For a €500 product, a two-week nurture sequence is sufficient. For a €20,000 B2B service, the sequence might span three months. This connects directly to what we describe in our article on sales automation.
3. Abandoned Cart / Incomplete Request (2–3 emails)
Someone started a checkout process or half-completed a form and stopped. That's not a lost lead — it's a lead that needs a nudge.
Example sequence:
- Email 1 (1 hour later): "You left something behind" — reminder with a direct link to continue.
- Email 2 (24 hours later): Add social proof: "500+ businesses chose us" or a brief testimonial.
- Email 3 (72 hours later): Urgency or incentive: limited offer, free extra, or simply "Can we help with anything?"
In e-commerce, abandoned cart sequences recover an average of 5–15% of lost orders. In B2B services, the percentages are lower but the deal values are higher, meaning every recovered lead contributes significantly.
4. Re-Engagement Sequence (2–4 emails)
Subscribers who haven't opened or clicked in 60–90 days are inactive. They cost you money (you pay per contact with most tools) and lower your deliverability. A re-engagement sequence tries to win them back — or cleans them out.
Example sequence:
- Email 1: "We miss you" — short, personal, with a link to your best recent content.
- Email 2 (7 days later): "Do you still want to hear from us?" — direct question with a button to update preferences.
- Email 3 (14 days later): "Last message" — if they don't respond, you unsubscribe them. No hard feelings, but a clean list is more valuable than a large one.
5. Customer Onboarding Sequence (4–6 emails)
After the sale, the real work begins: ensuring the customer succeeds with your product or service. An automated onboarding sequence guides new customers through the first steps, reduces support tickets, and increases retention.
Structure:
- Day 1: Welcome as a customer. Here are your login details / next steps / contact person.
- Day 3: "Have you completed [first action] yet?" Tips to get results quickly.
- Day 7: Checklist: is everything set up correctly? Common questions and answers.
- Day 14: "How's it going?" Short satisfaction survey (NPS or single question).
- Day 30: Cross-sell or upsell: "Now that you've mastered [product A], you might be interested in [product B]."

Email Automation Tools
Mailchimp
Best for: Startups and small businesses wanting a simple entry point.
Mailchimp offers a free plan up to 500 contacts with basic automation. The interface is intuitive, but automation capabilities are limited compared to more specialised tools. Good as a starting point; you'll outgrow it quickly if you want to build serious nurture flows.
Price: Free – €350/month depending on contacts and features.
ActiveCampaign
Best for: SMBs wanting serious automation without enterprise-tool complexity.
ActiveCampaign combines email automation with a built-in CRM. The visual workflow builder lets you create complex sequences with conditions, splits, and scoring. The strength is the combination: email + CRM + lead scoring in one tool.
Price: €49–€149/month.
HubSpot Marketing Hub
Best for: Businesses wanting email automation integrated with their CRM and sales process.
HubSpot's Marketing Hub is most powerful in combination with HubSpot CRM. Everything is integrated: a lead who opens an email automatically increases their lead score in the CRM. That makes it a natural choice if you're already using HubSpot for sales — something we also cover in our article on CRM automation.
Price: Free basic / €45–€800/month.
Make or n8n (for Custom Workflows)
If you want to connect existing systems without migrating to a new platform, Make and n8n are powerful alternatives. You build custom workflows that trigger emails from any system — your webshop, your accounting software, your own application. This requires technical knowledge or a partner to build it for you, but the flexibility is unlimited. Explore the possibilities of custom business automation.
Metrics That Matter
Not all numbers are equally important. Focus on these:
| Metric | Benchmark | What it tells you |
|---|---|---|
| Open rate | 20–30% | Whether your subject lines work and your list is engaged |
| Click rate | 2–5% | Whether your content is relevant and your CTAs effective |
| Conversion rate | 1–3% | Whether your sequence actually turns leads into customers |
| Unsubscribe rate | <0.5% per email | Whether you're communicating too often or irrelevantly |
| Revenue per email | Varies | The direct contribution to revenue |
Measure per sequence, not as a whole. Your welcome sequence might perform excellently while your nurture sequence underperforms — you want that distinction to optimise effectively.
Getting Started Step by Step
Step 1: Choose your first sequence. Start with the welcome sequence — it has the highest reach and the most impact per email. You'll learn the system on a sequence that's relatively straightforward.
Step 2: Write the emails. Keep them short (150–250 words), personal (use first names), and valuable (every email contains something useful, not just promotion). Also read how automating business processes works in the broader sense.
Step 3: Configure the triggers. Set when each email is sent. Test the flow by adding yourself as a test contact and running through the entire sequence.
Step 4: Launch and measure. Go live with a subset of your contacts. After two weeks: review open rates, click rates, and unsubscribes. Adjust where needed.
Step 5: Build the next sequence. Once your welcome sequence is running, build the nurture sequence. Then the re-engagement. Each sequence builds on the previous one and strengthens your overall email strategy.
