Email plug installations come with some default settings that let you start using it right away. To understand how to use these settings, it helps to understand how our email service works.
Yetto uses a service called Postmark for handling all email, inbound and outbound. When creating a new plug installation, we create a unique Postmark address for receiving emails for your inbox. Those addresses look something like this:
1A2S3D4F@inbound.postmarkapp.com
We call these canonical email addresses. You can send emails directly to this address, and those emails will show up in your Yetto inbox. These addresses cannot send emails, however.
To send outbound email, each plug installation also has a unique sender email address. These addresses are based on your organization name and your inbox name, and look like this:
OrgName@InboxName.yetto.email
When you respond to conversations in your Yetto inbox, the outbound message will come from this sender address. Since the sender address and the canonical address don't match, we set the reply-to address of the email to the canonical address, so all responses to your messages come back to the right place - your Yetto inbox.
These addresses are useful for experimenting with your team workflows before opening the inbox to customers. You can send and receive emails and set up labels and switches before going through the custom email configuration.
