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.
How PURIST uses this
This concept is built into every automation we deploy.
When PURIST builds your automation, SMTP / Transactional email is not an optional consideration it is part of the production standard. Our workflows are tested against edge cases, monitored 24/7, and built to handle what happens when things don't go as expected.
Every client workflow we deploy in the Operations category is designed with this principle in mind from day one not added as an afterthought.
Complexity level
