Outbound SMTP service will no longer be supported by Mailsac.
What Does this Mean for Me?
Mail will no longer be able to sent from Mailsac addresses or custom domains using the outbound Mailsac SMTP service.
If you are sending from the REST API, compose email form, or Unified Inbox we encourage you to seek out other SMTP sending services. Mailsac has always supported direct SMTP from anywhere, without a mail relay, as well.
Reasons for the Change
Email delivery is not an easy problem at scale.
Our customers, especially quality assurance teams, are using Mailsac as a receive-only service.
The likelihood that Mailsac’s outbound messages are delivered to the intended inbox has been trending lower over time, despite increased effort.
We made the decision to focus our efforts on improving our core product – disposable inbound email for testing.
