Inbox by TrueDialog

Development & testing environment

ctot.dev is the development environment for Inbox by TrueDialog — a programmatic email service that lets software agents and their operators exchange email through a governed API.

What this domain sends

Transactional email only — replies, notifications, and system messages exchanged between our agents, our team, and a small, known set of correspondents. No marketing, no bulk, no unsolicited mail.

Recipients

Known correspondents and transactional traffic only. We do not use purchased or rented lists. Sending is limited to development and integration testing, at low volume (on the order of tens of messages per day).

Authentication & deliverability

Mail from ctot.dev is authenticated with SPF, DKIM, and DMARC.
Bounces and complaints are delivered to dedicated Amazon SNS topics and processed automatically.
Bounced and complained addresses are added to a suppression list and are not retried; the account-level suppression list is honored.
Sending rates are monitored with CloudWatch alarms.

Compliance & opt-out

We comply with the AWS Service Terms and Acceptable Use Policy and honor opt-out requests. To opt out, or to reach the operators of this domain, reply to any message sent from ctot.dev.
