An automated email is a message you write once that goes out by itself when something happens: a form is submitted, an order is paid, a booking is two days away. For a small business the first wins are rarely newsletters. They’re the replies people expect and don’t always get, because whoever should send them is busy.
Start with those. Add marketing emails later, once you know which ones you’re allowed to send.
Two kinds of email, two sets of rules
Before building anything, sort each email into one of two groups.
Service emails respond to something the person did. Enquiry confirmations, order and booking confirmations, delivery updates, appointment reminders. They’re part of providing what was asked for.
Marketing emails promote something: offers, newsletters, “we haven’t seen you in a while” messages, product launches.
In the EU, marketing email to individuals needs their prior consent under Article 13 of the ePrivacy Directive. There is one exception. If you got someone’s email address while selling them a product or service, you can email them about your own similar products or services, as long as they were clearly given a free, easy way to object when you collected the address and in every message after that.
Where you rely on consent, the GDPR adds two practical duties. You must be able to show that the person consented (Article 7(1)), and withdrawing must be as easy as signing up (Article 7(3)). When someone objects to direct marketing, you stop using their data for it (Article 21(3)).
Double opt-in, where the subscriber clicks a link in a confirmation email before they’re added, is not written into either law. It’s still the simplest way to prove the address belongs to the person who signed up, and it keeps typos and fake addresses off your list. I’d use it for any newsletter.
Two caveats. Rules for emailing other businesses vary between EU countries, so check your national law before any cold B2B email. And this is a practical summary, not legal advice.
The order I’d build them in
1. Enquiry confirmation
Someone fills in your contact form. Within a minute they get an email that says what you received, who will reply and roughly when, based on your real working hours. Include a copy of their message so they can spot a wrong phone number.
A fictional example for a kitchen fitter:
Hi Maria, thanks for your message about a kitchen in Varna. We’ve got the details below. Petar handles new projects and will reply by the end of the next working day. If it’s easier to talk, you can call us on weekdays 9:00–17:00.
Nothing clever. It just stops people wondering whether the form worked, and gives them a reason to wait for you instead of contacting the next company on the list.
2. Welcome email for subscribers
Only for people who opted in. Say what they signed up for, how often you’ll write, and one thing worth doing next. If you use double opt-in, the confirmation email and the welcome can be the same message.
3. After the order or the job
Confirm what was bought or done and what happens next. A few days later, ask for a review. If it’s a Google review, ask every customer, not only the happy ones, and offer nothing in return. Google’s policies prohibit both incentives and selective asking. There’s more on that in our guide to Google Business Profile.
4. Follow-up on a quote that went quiet
One reminder, a few days after you sent a quote, from a real person’s address. It’s a reply to their own request, so keep it about that quote and nothing else. Consider making this an automatic task for a salesperson rather than an automatic email. The person can see context the system can’t, like a phone call that already happened.
5. Re-engagement for past customers
This one is marketing. It needs consent, or the existing-customer exception described above, and every message needs a working unsubscribe link.
Get the sending basics right
Send from your own domain, not a free Gmail or Outlook address. Then set up email authentication. Google’s email sender guidelines require everyone who sends to Gmail to have SPF or DKIM, and senders of more than 5,000 messages a day to have SPF, DKIM and DMARC plus one-click unsubscribe on marketing mail. Google also asks senders to keep the spam rate reported in Postmaster Tools below 0.3%. Most email platforms give you the DNS records to add, and you only do it once.
Use a reply-to address someone actually reads. A “noreply” address on an enquiry confirmation tells the customer you don’t want to hear from them.
Then test. Trigger each automation yourself, on a phone, and read what arrives. Check that names fill in correctly and that nothing lands in spam.
Where AI fits
Everything above runs on fixed rules: this trigger, this email. That’s enough for confirmations and reminders, and it’s predictable.
AI becomes useful when the reply depends on what the person wrote. A workflow can read an enquiry, pull the relevant details from your own price list or service notes, and draft a tailored answer for someone on your team to check and send. The person stays responsible for what goes out. If you’re weighing that up, the difference between chatbots and AI agents is worth reading first.
That review step is how we build AI workflows: the system prepares the work and a person approves it. If you’d like help deciding which emails to automate first, tell us how enquiries reach you today.
