A DocSend alternative for AI-generated proposals and decks
Sales and delivery teams now have agents that draft proposals, pitch decks, technical write-ups and SOWs in minutes, often as HTML. Exporting them to PDF and attaching them to an email throws away what makes them useful: you can't fix a typo after sending, and you lose track of which version the client has. Outbox publishes them as live links, one per person, with a password, an expiration and an alert when they're opened.
Why HTML beats a PDF attachment
An HTML deliverable is a live page: interactive pricing tables, embedded diagrams, responsive layouts that read well on a phone. It also stays editable. Your agent can apply the client's feedback and republish to the same link, so there's never a "v3-final-FINAL.pdf" thread.
How it works with Outbox
Give your agent an Outbox API key scoped to a client folder, for example clients/acme. The agent publishes the proposal there; it starts private.
When it's ready, create a share link for each person, with a passphrase and an expiration date, and send it. If something changes, the agent republishes to the same slug: the link stays the same and every version is kept, with a diff between them.
People you give comment access can leave comments anchored to the text, and you can accept their suggestions as a new version.
- The agent publishes clients/acme/proposal.
- You create a link for each person at Acme who needs to read it.
- You get an email when each one opens it; What I share shows who opened it and who hasn't.
- If someone hasn't opened it after 48 hours, Outbox reminds you.
What you see, and what you don't
Outbox records each open per link: who (the name you gave the link), how many times and when it was last opened. What it doesn't do is DocSend's page-by-page analytics: it doesn't measure how long someone spent on each section. If your sales process relies on that, DocSend is still the tool.
One folder per client, one key per agent
Folder-scoped keys keep each agent inside its client's folder, so a proposal for one account can't land in another's. Your library stays organized by client without anyone filing things by hand.
Pricing for a team
DocSend charges per user. In Outbox, links with a password, expiration and open alerts start on the Free plan, and Team is one flat price for the whole company: Free plan; Pro $5/mo; Team $49/mo per team (early access). Readers never pay.
When DocSend is still the better fit
DocSend is built around PDFs and slide files, with page-by-page engagement analytics, email capture and data rooms. If your process depends on those, keep it. If your agents already produce HTML and you want to share it, iterate on it and keep every version in one place, Outbox is the simpler path. Many teams use both.

Frequently asked questions
Does Outbox show how long the client spent on each page?
No. It shows who opened each link, how many times and when, with an email alert. Time-per-page analytics is DocSend's territory.
Can I upload a PDF?
Outbox publishes HTML and Markdown. If your deliverable is a hand-built PDF, DocSend is the better fit.
Does the client need an account?
No. They open the link in any browser; if you set a passphrase, they type it once.
