How it works
From domain setup to inbox placement
Transactional and bulk email over a simple API or SMTP relay, with the authentication and reputation work that keeps mail out of spam.
Authenticate
SPF, DKIM, and DMARC
We set up domain authentication and a warmed sending identity, because deliverability starts with proving the mail is genuinely yours.
Connect
API or SMTP relay
Point your existing SMTP configuration at us or call the REST API. Templates with variables let product and marketing ship without a deploy.
Send
Transactional and bulk lanes
Password resets and receipts route on a priority lane, separate from newsletters, so a large campaign never delays a time-critical email.
Analyse
Opens, clicks, bounces, complaints
Event webhooks and dashboards track engagement and list hygiene, with suppression handled automatically to protect your reputation.
