Channels & providers
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.
