Studio plan and the revised word…
Brand refresh: final direction
Re: Q4 roadmap sync
Contract signed, thank you
Hi there,
The revised plan is ready. I moved the workspace review to Thursday and added the new approval step you asked for.
Let me know if everything looks right on your side.

Built for people who want their mail back.
ONE WORKSPACE, FOUR SUPERPOWERS
Everything your email needs.
Nothing you don’t.
InboxFly connects the inboxes, agents and sending tools you already use — inside the Cloudflare account you already trust.
Personal mail
Full inboxes on your own domain. Read, search, label, forward and reply without another mail provider in the middle.
Open webmail →Agent Mail
Give your AI agent a real address, MCP access and a clean inbox — with limits, audit trails and human control.
Meet Agent Mail →SenderFly
One REST + MCP API across Resend, SendGrid, Postmark, Sender.net, SMTP and more. Automatic failover, your keys.
Explore SenderFly →HelpFly
Shared support inboxes, brands, forms and reporting — without adding another helpdesk subscription.
Open HelpFly →YOUR INBOX, YOUR RULES
A calmer inbox.
On infrastructure you own.
InboxFly runs as a Worker in your Cloudflare account. Mail lands in your MailboxDO, bodies stay in your R2, and your provider keys never leave your instance.
- Unlimited addresses on domains you control
- Labels, rules, forwarding and full-text search
- Built-in sending profiles and provider routing
