MailInApp
Interactive emails people can answer inside the inbox: polls, checkout, RSVP, NPS and more.
MailInApp turns email into something people can act on without leaving the inbox. Recipients vote, book, pay or rate right in the message, and every email still renders correctly in clients that don't support interactivity.
Features
What MailInApp does
Interactive blocks
45+ no-code blocks for polls, checkout, RSVP, NPS, forms and more, assembled in a visual editor.
Renders everywhere
A 3-tier fallback engine: kinetic email where it's supported, a static version with a live view link, and a classic Outlook version.
Journeys and sending
Automated journeys, native sending with your own domain, and a domain mailbox with IMAP.
Measure and improve
A/B tests and heatmaps show which content gets answered, not just opened.
APIs and AI
Send and Embed APIs for developers, plus Claude and Gemini connectors and MCP support.
