SMTP / Transactional email
Sending automated one-to-one emails triggered by specific events (invoice generated, password reset, appointment confirmed). Contrast with marketing email (bulk sends). Services include SendGrid, Postmark, and AWS SES.
Expert insight
Transactional email sent via a shared or poorly-configured SMTP relay without proper SPF, DKIM, and DMARC records lands in spam far more often than the content would suggest, deliverability is determined more by domain reputation and authentication setup than by what the email says.
In a real workflow
Order confirmations are sent through a transactional email service with proper SPF, DKIM and DMARC.
