About
Mailtrap provides separate services for testing application email, sending production messages and running marketing campaigns. Email Sandbox captures development or staging mail so developers and quality assurance teams can inspect it before a real send. Email API/SMTP delivers production messages, while Email Marketing supplies campaign, contact and segmentation tools.

The sending service provides delivery analytics, tracking, suppression management and logs, with retention and operational controls varying by plan. Current pricing also documents inbound email through dedicated addresses, webhooks and API access. Developer resources include SDKs and integrations for environments such as Supabase and Vercel, plus MCP tools for supported AI workflows.
The products have distinct quotas and plans. The published free sending plan includes 4,000 monthly emails, with sending and receiving sharing the quota; the free Sandbox plan has a separate allowance of 50 test emails. Larger plans change capacity, retention, support and security controls. Teams should therefore price the testing and production workloads separately.
Published 2022 customer stories describe Calendly’s email testing, Kinsta’s collaboration between developers, designers and quality assurance staff, and The Software House’s email development work.
MCP runs locally, and live sending requires a verified sending domain.
