About Mailtrap
Mailtrap pulls cross-client render testing into the sandbox that already holds the mail.
The platform spans the whole email lifecycle: Mailtrap Local for the development loop, the hosted sandbox for testing, sending, Inbound for receiving, and Automated Domain Reputation Monitoring watching the result. Recent work had turned to trust and abuse controls — a recipient-domain allowlist so stolen credentials cannot send outside it, and DNS-TXT verification of additional company domains that touches neither SPF nor DKIM and grants no sending rights. Device Previews now adds something different: rendering a captured message across more than 100 real client and device configurations, one screenshot each, light and dark modes compared side by side.
