Setting up email sending

Send through AWS SES, your own SMTP, or Gmail.

Configure how email goes out under Settings → Provider settings. OneSimpleInbox supports AWS SES, a custom SMTP/mail relay, and Gmail.

Choosing a path

Gmail is quick for personal/transactional sending; SES or SMTP suit higher volume and bulk campaigns. If you signed in with Google, you can use that Gmail as your first email. A channel must be active before the dashboard shows real activity.

Deliverability

Align your From domain and set up sender authentication (SPF/DKIM/DMARC) on the domain you send from so messages land in the inbox.
