About Mailtrap
Mailtrap is building the whole email lifecycle around the sandbox it started with.
Mailtrap has moved well past email testing this quarter. Inbound went generally available in June, so the platform now receives mail as well as sending it; a free open-source local sandbox shipped in July; and August brought aggregated domain reputation monitoring. Around those, the app picked up a redesigned navigation, a notification center, an agent-oriented setup flow with MCP server and skills, and email logs plus sending stats exposed through the official SDKs.
