How-to
Set up emails that send themselves when something happens: triggers, templates, sequences, deliverability and the legal basics, step by step.
Updated 5 min read
The short answer
Automatic emailing means a system sends an email when something happens, such as a form submission or a purchase. Choose the trigger, write the template, connect it to your own domain, test it and measure replies.
Key points
Step by step
Follow them in order. Each step makes the next one easier.
Choose the event that starts the email: a new lead, a booked call, a paid invoice or a quiet customer.
Draft a short email with a clear purpose. Add fields such as name and date so it feels personal.
Send from your business address and set up SPF, DKIM and DMARC so inboxes trust you.
Add follow-ups with clear delays and exit rules, so people stop receiving emails once they reply or buy.
Include your postal address and a working opt-out link, and honor opt-outs on time.
Send test cases to yourself first. After launch, track replies, opt-outs and spam complaints.
Automatic emails are messages a system sends for you when a rule is met. A customer fills a form and gets a confirmation. A lead goes quiet and gets a reminder.
The best ones answer a moment the reader already cares about. That is why a trigger comes before any copy. For ideas that go beyond email, see our guide to AI in email marketing.
Start with moments that happen every week. They pay back fastest.
A good email automation workflow, or email marketing automation flow, has a start, a delay and an end. Define what removes someone from the flow: a reply, a purchase or an opt-out.
Without exit rules, people keep getting emails they no longer need. Put one condition at every step.

spam rate Google asks bulk senders to stay under
Inboxes check who you are before they show your message. Google asks senders to set up SPF and DKIM authentication for the domain, and DMARC as well [source: Google].
Google also asks bulk senders to keep the spam rate reported in Postmaster Tools below 0.30%. Send only to people who expect to hear from you.
$53,088
maximum penalty per violating email
In the US, the CAN-SPAM Act sets the rules for commercial email. Under CAN-SPAM, each separate violating email can cost up to $53,088 in penalties, according to the FTC.
Your message must include your valid physical postal address. Unsubscribes must take effect within 10 business days. Once someone opts out, you cannot sell or transfer their address.
AI can draft a first version, adapt it to the recipient and sort replies.
AI drafting saves real time: an NBER six-month study found AI email tool users spent two hours less per week in their inbox.
Keep a person approving the templates and any reply that involves money, a complaint or an exception. If you want this connected to your CRM and inbox, our marketing automation work does exactly that.
