Prospero vs AcyMailing: at a glance
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 AcyMailing?
AcyMailing 11.1.2 closes holes that let strangers read or unsubscribe any subscriber.
AcyMailing is a Joomla and WordPress email marketing extension. Release 11.1.2 is a security update: it fixes an unauthenticated leak of subscriber data including the subscriber key, anonymous unsubscribing of any known address, logged-in users changing other people's subscriptions, unchecked post-subscription redirects and campaign archive pages opening without permission. It follows 11.1's privacy work, a per-subscriber tracking switch and fixed one-click unsubscribe.

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.
AcyMailing

AcyMailing 11.1.2 closes holes that let strangers read or unsubscribe any subscriber.
◆ Current state
AcyMailing is a Joomla and WordPress email marketing extension. Release 11.1.2 is a security update: it fixes an unauthenticated leak of subscriber data including the subscriber key, anonymous unsubscribing of any known address, logged-in users changing other people's subscriptions, unchecked post-subscription redirects and campaign archive pages opening without permission. It follows 11.1's privacy work, a per-subscriber tracking switch and fixed one-click unsubscribe.
◆ Where it's heading
Since the 11.0 security rework in July, AcyMailing's releases alternate between privacy features and fixes for flaws in how subscriber actions are authorized. 11.1.2 shows the 11.0 rework left gaps in the subscription paths, now patched with ownership checks and security tokens.
◆ Prediction
A security advisory with full details is promised once users have had time to update, and further 11.1.x patches are likely as those details invite scrutiny of related code paths.
