Send the right email to the right person at the right time — automatically, with zero coding
Here is everything you need to follow this guide:
If you can send an email, you can automate an email. That is the whole idea.
OpenClaw has a free tier that lets you run automations, connect your email, and send messages without entering a credit card. You can build everything in this guide on the free plan.
If you grow and need more volume, here is what the paid plans look like:
| Feature | Free Tier | Pro ($19/month) | Business ($49/month) |
|---|---|---|---|
| Automations | 5 active | Unlimited | Unlimited |
| Emails per month | 500 | 10,000 | 50,000 |
| Email connections | 1 provider | 3 providers | Unlimited |
| Follow-up sequences | 1 active | Unlimited | Unlimited |
| Personalization variables | Yes | Yes | Yes + custom fields |
| Priority support | Community | Live chat |
OpenClaw is free with limits — 5 active automations and 500 emails per month. For a solo business or freelancer, that is plenty to start.
Most small business owners run on the free tier for 2-3 months before deciding if they need more.
Bottom line: Start free. Build your first automation. See real results. Upgrade only when your email volume demands it.
Every chapter follows the same simple framework: WHAT, HOW, and WHEN. First, we explain what the topic is and why it matters. Then, we show you exactly how to do it — step by step, one click at a time. Finally, we tell you when to use it and how often.
By the end of all 8 chapters, you will be able to: connect your email provider, build a personal welcome email, create multi-step follow-up sequences, use personalization so every email feels handwritten, avoid spam folders, and copy 12 ready-to-use email templates.
Meet Dana. She runs a small candle business out of her garage. Every night after packing orders she would sit down and type the same welcome email to every new customer. One by one. Copy, paste, change the name, hit send. It took about 45 minutes a night.
One Tuesday she set up email automation in OpenClaw. It took her about 20 minutes. Now every single customer gets a warm, personal welcome email within 60 seconds of placing an order. Not 60 minutes. Not the next morning. Sixty seconds.
Here is what happened in the first month:
Dana is not a tech person. She does not write code. She just followed the steps you are about to follow in this guide.
Email automation is not about replacing you. It is about cloning the best version of you. The version that always responds quickly, never forgets a follow-up, and always says the right thing at the right time.
Here is how it works: you write an email once, then tell OpenClaw when to send it and who to send it to. From that moment on, every person who matches your rules gets that email automatically. You write it once. It works forever.
Pro Tip: The best automated emails do not feel automated. They feel like a thoughtful person sent them at exactly the right time. That is the goal.
Any time you find yourself sending the same type of email more than twice a week. Welcome emails, order confirmations, follow-ups, appointment reminders — if it is repetitive, it should be automated.
Before OpenClaw can send emails for you, it needs permission to use your email account. Think of it like giving a trusted assistant the keys to your mailbox. They can send letters for you, but they cannot read your personal mail unless you specifically ask them to.
Log in to OpenClaw and click Settings in the left sidebar.
Click Connections at the top of the Settings page.
Find the Gmail card and click Connect. A Google sign-in window will pop up. Sign in with the Gmail address you want to send from. Google will ask you to allow OpenClaw to "send email on your behalf." Click Allow.
Google Workspace users: If your company uses Google Workspace (the business version of Gmail), your admin may need to approve OpenClaw first. Ask them to go to Admin Console, then Security, then API Controls, and add OpenClaw to the approved list.
In OpenClaw, go to Settings then Connections. Find the Microsoft Outlook card and click Connect.
Sign in with your Microsoft account. Microsoft will ask you to grant OpenClaw permission to send emails. Click Accept.
Yahoo requires a special app password. Go to login.yahoo.com, click Account Security, scroll down and click Generate App Password. Select "Other App," type "OpenClaw," and click Generate. Copy the 16-character password Yahoo shows you.
Back in OpenClaw, go to Settings then Connections. Find Yahoo Mail and click Connect. Paste the app password when prompted.
| Provider | Daily Limit (Free) | Daily Limit (Paid) | Safe Range |
|---|---|---|---|
| Gmail | 500 emails | 2,000 (Workspace) | 100–200/day |
| Outlook | 300 emails | 10,000 (Microsoft 365) | 100–500/day |
| Yahoo | 500 emails | 500 | 50–100/day |
Use the email address your customers already know. If people email you at hello@yourbusiness.com, connect that one. Consistency builds trust. You can connect more than one email account and pick which one to use for each automation.
After connecting, send a test email to yourself. In OpenClaw, create a quick automation with a Manual trigger and a Send Email action. Put your own email in the To field. Write "Test from OpenClaw" as the subject. Click Test. Check your inbox. If the email arrives, you are ready to go.
You only need to connect your email once. After that, every automation you build can use it. Come back to this chapter if you switch email providers or want to add a second email account.
Your welcome email is the first impression your business makes after someone signs up, buys something, or fills out a form. Studies show that welcome emails get opened 4 times more often than regular marketing emails. That makes this the single most important email you will ever send.
Click New Automation in your dashboard. Give it a name like "Welcome Email — New Customers."
Click Add Trigger. Choose one of these depending on your situation:
Click Add Action and choose Send Email. Fill in:
Click Test in OpenClaw. Check your own inbox. Make sure the email looks right, the subject line is correct, and the variables are filling in properly.
Quick Win: A medium-sized marketing agency set up this exact welcome email for a client's Shopify store. Cart abandonment follow-ups were added next. Within 30 days, the client recovered $4,200 in lost sales.
Every business needs a welcome email. Every single one. If someone gives you their email address, send them something within 60 seconds. This is non-negotiable.
James runs a financial consulting firm with 15 employees. His team was losing leads because nobody followed up after the first meeting. Prospects would say "let me think about it" and then disappear. His team was closing 12 percent of leads.
He built a 5-email follow-up sequence in OpenClaw. After every first meeting, the prospect automatically received a thank-you email within an hour, a case study email 2 days later, a pricing breakdown on day 4, a testimonial roundup on day 6, and a "still interested?" nudge on day 10. His close rate jumped to 28 percent. Same leads. Same team. Just automated follow-ups.
Click New Automation. Name it "New Lead Follow-Up Sequence."
Choose the trigger that matches how leads enter your system — form submission, new spreadsheet row, or webhook.
This sends immediately. Keep it warm and short. Confirm what they signed up for. Set expectations for what comes next.
After the first email, add a Delay step. Set it to 2 days. This pauses the automation before sending the next email.
Share something useful — a tip, a case study, a quick win they can act on today. Do not sell. Just help.
Wait 3 more days before the final email.
Now you can make a gentle offer. Invite them to book a call, check out your product, or reply with a question. Keep it low-pressure.
Pro Tip: The enterprise marketing department at a 500-person SaaS company tested this exact 3-email cadence and found that Email 2 (the value email) had the highest reply rate of the entire sequence. Give before you ask.
| When to Send | Purpose | Tone | |
|---|---|---|---|
| Email 1 | Immediately | Welcome + set expectations | Warm, personal |
| Email 2 | Day 2–3 | Deliver value (tip, story, resource) | Helpful, generous |
| Email 3 | Day 5–7 | Soft ask (book a call, try the product) | Casual, low-pressure |
Every time you get a new lead, subscriber, or customer who is not ready to buy yet. A follow-up sequence keeps you top of mind without you doing anything. Set it up once. It runs forever.
Rachel runs an online plant shop. She noticed that her generic emails got a 15 percent open rate. Then she added the customer's first name to the subject line. Open rate jumped to 26 percent. She added the name of the plant they ordered to the email body. Click rate doubled.
Personalization variables are placeholders that OpenClaw fills in with real data for each person. The email says "Hi Rachel, your Monstera is on the way!" instead of "Hi, your order is on the way!" Small change. Huge difference.
In OpenClaw, variables look like this: {{first_name}}, {{email}}, {{order_total}}. When the email sends, OpenClaw replaces those placeholders with the real data from your trigger.
| Variable | What It Inserts | Example Output |
|---|---|---|
{{first_name}} | Person's first name | Rachel |
{{email}} | Their email address | rachel@example.com |
{{company}} | Company name | Green Thumb Gardens |
{{order_total}} | Order amount | $47.99 |
{{product_name}} | What they ordered | Monstera Deliciosa |
{{signup_date}} | When they signed up | April 12, 2026 |
Always set a fallback. If OpenClaw does not have someone's first name, you do not want the email to say "Hi {{first_name}}." In the variable settings, set a fallback like "there" so it reads "Hi there" instead. Small detail. Big professionalism.
Every single automated email should use at least the first name variable. It takes 5 seconds to add and it makes every email feel 10 times more personal.
Tom runs a mid-size ecommerce brand with 50 employees. His marketing team built a beautiful email campaign. They hit send on 10,000 emails. Open rate: 3 percent. Not 30. Three. Almost every email went straight to spam.
The problem was not the content. It was deliverability — the technical stuff that decides whether your email lands in the inbox or the junk folder. This chapter shows you how to stay in the inbox.
Do not send 500 emails on day one. Start with 20 per day. Add 20 more each day. Gmail and Outlook watch for sudden spikes and flag them as spam.
Never buy email lists. Never scrape emails from websites. Only email people who signed up, bought from you, or gave you their address directly.
Send from "Dana at Sweet Light Candles" not "noreply@company.com." People open emails from people, not from robots.
Words like "FREE!!!", "Act now!", "Limited time offer!!!", and "Click here immediately" trigger spam filters. Write like a normal person talking to a friend.
Emails that are all images and no text look like spam to filters. Use mostly text with one or two images.
This is legally required in many countries (CAN-SPAM in the US, GDPR in Europe). OpenClaw adds one automatically. Do not remove it.
Remove email addresses that bounce. Remove people who have not opened an email in 90 days. A smaller, engaged list beats a large, dead list every time.
Quick Win: An enterprise HR department at a Fortune 500 company applied rule #1 (warm up volume) to their internal newsletter and saw open rates jump from 22 percent to 61 percent in 3 weeks. The IT spam filter had been eating their emails.
Review these rules before launching any new email automation. Come back to this chapter any time your open rates drop below 20 percent — that is your signal that deliverability needs attention.

| Problem | Likely Cause | Fix |
|---|---|---|
| Emails not sending | Email provider disconnected | Go to Settings > Connections and reconnect your email |
| Emails going to spam | Sending too many too fast | Warm up volume slowly (Chapter 6). Check for spam trigger words. |
| Variables showing as raw text | Wrong variable name or missing data | Double-check variable names match your trigger data. Set fallbacks. |
| Automation not triggering | Trigger misconfigured | Test the trigger separately. Make sure the automation is turned ON. |
| Double emails being sent | Duplicate triggers or no filter | Add a filter step to check if the email was already sent. |
| Low open rates | Bad subject lines or wrong send time | Test subject lines with the recipient's name. Send at 9–10 AM local time. |
Action Step: Do the "Today" items right now. Not later. Not tomorrow. Right now. Twenty minutes is all it takes to have your first automation live.
Come back to this action plan every day this week. Check off each item as you complete it. By the end of the week, you will have a fully automated email system that sends welcome emails, follows up with leads, and re-engages inactive customers — all without you touching a single email.
