Welcome to Transactional Email
Send receipts, subscription notices, and account notifications from HubSpot workflows, using emails you design in HubSpot.
Overview
Section titled “Overview”Transactional Email is a HubSpot app that sends one-to-one transactional emails — receipts, subscription notices, account notifications — from any HubSpot workflow. You design the email in HubSpot’s email editor, add the Send transactional email action to a workflow, and the app delivers the email from your own domain.
You don’t need a developer, a separate email-provider account, or HubSpot’s transactional email add-on. Domain authentication, warm-up, bounce handling, and suppression are built in and run automatically.
The building blocks
Section titled “The building blocks”- Templates are ordinary HubSpot marketing emails built with the standard
drag-and-drop modules. Tokens like
{{ contact.firstname }}fill in from the recipient’s contact record and primary company. - The workflow action, Send transactional email, sends one template to one recipient and returns a send status your workflow can branch on.
- Sender profiles are saved From names, addresses on your sending domain, and reply-to addresses. You pick one from a dropdown instead of typing addresses. Until you go live, a built-in sandbox sender works with no setup.
- Your sending domain — ideally a subdomain like
notify.acme.com— is where live emails come from. You prove you own it by publishing a few DNS records. - The content review checks every template version automatically to make sure it’s transactional, not promotional, before it can send.
Where things live
Section titled “Where things live”Transactional Email has two screens inside HubSpot, both under Marketplace apps → Transactional Email:
- App Home shows your setup checklist, usage, sending status, domain health, errors, reporting, the send log, and a billing summary.
- Settings is where you manage your Sending domain, Sender profiles, Templates, Billing, Alerts, and Sending. Super Admins can change settings; everyone else sees them read-only.
From install to live
Section titled “From install to live”- Install the app from the HubSpot App Marketplace. Your account starts in the sandbox: 20 free test sends, from our shared sandbox address.
- Send a test email from a workflow with the built-in sandbox sender to see the whole flow work.
- Add your sending domain, publish its DNS records, and create a sender profile on it.
- Accept the Acceptable Use Policy and subscribe. Once your domain verifies, live sending starts and warm-up begins.
