What is AcyMailing?
AcyMailing spent 11.0 on a security rewrite and is now paying down the regressions.
Patch releases arriving every few days since the 11.0.0 major. The 11.0.x line is dominated by fixes to what the rewrite disturbed — automation conditions, campaign send settings, custom field handling, add-on integrations — with small improvements alongside, such as REST API errors when a campaign targets disallowed lists and faster module insertion in emails.
What is Gumloop?
Gumloop is building the enterprise floor under an agent it now ships pre-assembled
Gumloop's window splits cleanly in two. On one side is Gumball, its first agent customers do not have to build, arriving with standing jobs — a morning briefing, meeting prep, and an inbox that sorts and drafts. On the other is the administrative apparatus an enterprise buyer demands: managed tunnels to private MCP servers, model access by role, approval routing, bring-your-own Fireworks keys, and GitHub-synced skill libraries.

AcyMailing
5.0MKT AUTO
AcyMailing spent 11.0 on a security rewrite and is now paying down the regressions.
◆ Current state
Patch releases arriving every few days since the 11.0.0 major. The 11.0.x line is dominated by fixes to what the rewrite disturbed — automation conditions, campaign send settings, custom field handling, add-on integrations — with small improvements alongside, such as REST API errors when a campaign targets disallowed lists and faster module insertion in emails.
◆ Where it's heading
The arc is consolidation, not expansion. 11.0.0 reworked the codebase for security and added GDPR-aware pixel tracking; 10.11.1 before it patched a SQL injection. Since then the work has been stabilizing that base, and the attachment fix in 11.0.3 even asks administrators to re-upload files or correct permissions.
◆ Prediction
Expect continued 11.0.x patches closing regressions from the rewrite before any new feature work resumes.
Gumloop
7.5MKT AUTO
Gumloop is building the enterprise floor under an agent it now ships pre-assembled
◆ Current state
Gumloop's window splits cleanly in two. On one side is Gumball, its first agent customers do not have to build, arriving with standing jobs — a morning briefing, meeting prep, and an inbox that sorts and drafts. On the other is the administrative apparatus an enterprise buyer demands: managed tunnels to private MCP servers, model access by role, approval routing, bring-your-own Fireworks keys, and GitHub-synced skill libraries.
◆ Where it's heading
Connector expansion continues at a steady clip — Azure, Meta Ads, DataForSEO, Sprout Social, SharePoint, NotebookLM, Zendesk, Gong — but it is no longer the story. The center of gravity has moved to who may use which model, where agents may reach, and who approves it, which is the vocabulary of a platform being bought by organizations rather than adopted by individuals. Distribution is moving the same direction, with agents pushed into Slack workspaces and reachable by people who have no Gumloop account.
◆ Prediction
Expect Gumball to graduate from beta with more standing jobs attached to the connectors already in the catalog, and expect the governance surface to keep thickening around it — audit and spend controls are the obvious gaps next to the role and approval work already shipped. The Outlook parity push suggests Microsoft-side coverage will continue to close against the Google-side features.
