Every Shopify store runs on a stream of events — orders placed, paid, fulfilled, cancelled; products created and updated; customers signing up. Shopify emails customers about a handful of these with its standard notifications, and everything else is on you. That's how merchants end up doing follow-up by hand: the "your custom order is confirmed" email, the heads-up to the warehouse address when a big order lands, the note to a supplier when stock changes.
The usual advice is "get a marketing automation platform," which is like being told to buy a truck because you need a wheelbarrow. Klaviyo-class tools are built for campaigns and flows around marketing; they're heavy, priced by contact list, and overkill when what you actually want is: when X happens in my store, send this email. That's an automation problem, not a marketing problem — and it has a much lighter answer.
Event-driven email, in plain terms
Email Automator listens to Shopify's webhook events and sends an email when one fires. Setup is three decisions, all made in a dashboard, none requiring code:
- Pick a trigger: any Shopify webhook event — order created, paid, fulfilled or cancelled, product created or updated, customer created, and many more.
- Design the email: a no-code editor where you drop in dynamic fields from the triggering event — order number, line items, customer name, product details.
- Choose the recipient: the customer, your own team, a supplier, a 3PL — any address, decided per rule.
Add conditions and filters so the right event sends the right email — only orders over a threshold, only products in a given collection, only customers from a specific country — and the rule runs hands-free from then on. Because it fires on real webhooks, it triggers every single time, not on a polling schedule that misses things.
What merchants actually automate with it
- Operational hand-offs: a formatted email to your fulfillment partner the moment an order is paid, with exactly the fields their team needs — no more copy-pasting order screens.
- High-value order alerts: a message to the owner's inbox when an order crosses $500, so the white-glove treatment starts immediately.
- Custom customer touches: follow-ups Shopify's standard notifications don't cover — care instructions when a specific product ships, a thank-you for a first order, a heads-up when a pre-order product's status changes.
- Internal bookkeeping: a record to accounting when an order is cancelled or refunded, carrying the numbers they'd otherwise dig out of the admin.
Where it sits next to your other tools
Email Automator doesn't replace your marketing platform — newsletters, abandoned-cart flows and segmentation stay where they are. And if you want alerts in Slack or SMS rather than email, that's what Easy Alerts does. The Email Automator lane is transactional and operational email triggered by store events, designed once and then forgotten: the follow-up that used to be a sticky note on someone's monitor, now guaranteed by a webhook.
Set it up once, stop thinking about it
Plans start at $4.99/month with a free trial, which is roughly the cost of ten minutes of the manual follow-up it eliminates. Install Email Automator, build the one rule you've been doing by hand the longest, and let it run for a week. The measure of good automation is that you forget it exists — right up until you notice nothing has slipped through in a month.
