What is Prospero?

Prospero is turning proposals from documents into instrumented, reusable assets.

Prospero builds and sends business proposals, with templates, a content library, e-signature and CRM connections around them. The releases over the past nine months form a steady, unhurried cadence of practical additions: catalogs and saved deliverables for reusing priced line items, content locking to protect approved sections, bulk actions across proposals, form builder fields, HubSpot and Make.com integrations, and now page-by-page analytics on how prospects read a proposal.

What is Sender?

Sender put its campaign and automation data behind an MCP server, moving reporting out of its own dashboard.

Sender is an email marketing platform that has spent the past year filling in platform basics — transactional email and a rebuilt dashboard in December, a refreshed email builder and brand settings in January, ecommerce reports extended to the Standard plan in March, and a rebuilt subscriber import in August. The newest release breaks that pattern: an MCP server that lets an AI assistant query campaign dashboards, automation reports and prior send history directly.

Prospero vs Sender: editorial side-by-side

Prospero is turning proposals from documents into instrumented, reusable assets.

◆ Current state

Prospero builds and sends business proposals, with templates, a content library, e-signature and CRM connections around them. The releases over the past nine months form a steady, unhurried cadence of practical additions: catalogs and saved deliverables for reusing priced line items, content locking to protect approved sections, bulk actions across proposals, form builder fields, HubSpot and Make.com integrations, and now page-by-page analytics on how prospects read a proposal.

◆ Where it's heading

Two consistent threads. The first treats proposal content as a reusable asset rather than a document — catalogs, saved deliverables, locked sections and templates all reduce how much of each proposal is written from scratch. The second instruments what happens after the proposal is sent, moving from delivery and signature toward telling a salesperson which pages held attention and which were skipped. The AI writing assistant sits alongside both without yet being connected to either.

◆ Prediction

Engagement data is now captured per page but presented for a human to read; the natural next step is acting on it — alerting when a prospect revisits pricing, or feeding the analytics back into template suggestions.

Sender put its campaign and automation data behind an MCP server, moving reporting out of its own dashboard.

◆ Current state

Sender is an email marketing platform that has spent the past year filling in platform basics — transactional email and a rebuilt dashboard in December, a refreshed email builder and brand settings in January, ecommerce reports extended to the Standard plan in March, and a rebuilt subscriber import in August. The newest release breaks that pattern: an MCP server that lets an AI assistant query campaign dashboards, automation reports and prior send history directly.

◆ Where it's heading

The platform work was about reaching feature parity with larger competitors. The MCP server is a different kind of move, treating Sender's data as something to be consumed by an assistant the customer already uses rather than only through Sender's interface. Note that the feed mixes tutorials and educational posts with genuine release notes, so cadence here overstates shipping volume.

◆ Prediction

Expect write actions to follow read access — creating campaigns or triggering automations through the same server — since reporting alone is the easier half. The entries do not describe the permission model, which is the part that will determine how far this can go.
