Sandbox Glossary
Sandbox API - Compatible with most programming languages, uses the REST protocol, and returns calls in JSON format. Here's the link to the API documentation. With API, you can take actions related to an sandbox, a project, email forwarding, email content, message headers, and more.
CORS Domains - CORS is Cross-Origin Resource Sharing. It’s a mechanism that allows restricted resources to be requested from another domain outside the domain from which the first resource was served. You can specify a list of domains that will have access to API.
Sandbox - A virtual sandbox with its own credentials to organize your emails. Typically, users have sandboxes for different environments, i.e. staging, development, and testing.
POP3 - Stands for Post Office Protocol 3. It’s among the most widely used protocols for receiving various emails.
Project - Sandboxes can be grouped into different projects to separate testing environments, companies, and projects you work on. Note that the number of projects is limited based on your plan.
STARTTLS - It’s an email protocol command that relays security information between an email server and an email client. The command shows an email client that Gmail, for example, wants to upgrade to a secure connection with TLS or SSL. STARTTLS is also commonly used with IMAP.
Miscellaneous Terms
Email Headers - All the original values of the email headers displayed as a table.
HTML Source - The HTML source code of an email that you send.
MTA - Message (or Mail) Transfer Agent. It’s the software that relays emails between senders’ and recipients’ computers via SMTP. To find out more about MTA, check out our related blog post.
MTA Settings - When setting up a sandbox, you get the SMTP settings to copy-paste into your MTA. That way, your MTA will use Mailtrap servers.
RAW - It’s your processed email consisting of a series of required and optional text headers followed by a message body. These details may be important for diagnosing email delivery issues.
Text - The plain text version of an email. If your email has only an HTML version, the Text tab won’t be available. This is true the other way around, too.
