Product Overview
MarkRelay gives your team one place to receive email, reply from shared addresses, build reusable designs, send broadcasts, and connect email to software or AI agents. It runs in your Cloudflare account under your own domain.
One workspace for every email workflow
Multi-domain webmail
Work across all authorized inboxes, search conversations, manage folders, compose, reply, forward, and handle attachments.
Templates and broadcasts
Design responsive emails, personalize recipient data, schedule campaigns, and follow engagement from one workflow.
Email API and webhooks
Send and manage email over HTTP, then receive signed inbound events in your application.
Team and agent access
Give each person or integration access only to the mailboxes it needs.
Built for Cloudflare
MarkRelay uses Cloudflare Workers for the application, D1 and R2 for your workspace data, Email Routing for inbound mail, Send Email for outbound mail, and Queues for background delivery. The licensed application is deployed to your account, so the runtime remains under your Cloudflare administration.
Common ways to use MarkRelay
- Run support, billing, partnerships, and operations mailboxes across several domains.
- Let a team work from shared addresses without sharing passwords.
- Send newsletters, product announcements, and customer updates from reusable templates.
- Add transactional email and inbound processing to an application with a clean HTTP API.
- Give an AI agent a dedicated, tightly scoped mailbox.
