Email infrastructure
Transactional and marketing email delivery API
Who it is for
Built for Developers–Enterprise teams.
Deliverability controls
Review authentication, suppression, bounce handling, monitoring, and the support available during delivery issues.

Check API, SMTP, event, template, and integration requirements against your application or sales stack.
When it fits
Use it when
- You send from your own domains and need authentication.

- The product workflow needs events, not only a mailbox.
Skip it when
- You can stay on a simple mailbox provider.
- No one will watch deliverability after go-live.
How to start
Separate marketing from sales mail
Don’t blast from the domain you use for 1:1 outreach.
Authenticate everything
SPF, DKIM, DMARC before volume.
Watch bounces daily
Infrastructure problems show up as reputation, not as a pretty dashboard.
