What is AcyMailing?

AcyMailing spent its 11.0 cycle on privacy plumbing and a security rewrite, not features.

AcyMailing crossed into 11.0 at the end of July, and the release carried a reworked codebase aimed at security plus a GDPR-driven option for handling pixel tracking. The two follow-up patches since have been almost entirely corrective — automations display, followup creation, multilingual campaigns, and restoring the pot file that custom translations depend on. The 10.11 line before it patched an SQL injection and added toggles for IP collection and a statistics recording delay.

What is Buttondown?

A near-daily fix stream, with flexible monthly RSS scheduling the only real addition.

Buttondown publishes a dated entry almost every day, and the overwhelming majority are single bug fixes, several credited by name to the subscriber who reported them. The current window is nine-tenths repair work — stretched newsletter icons in the archive, a portal 403 for subscribers with many accounts, rejected WebP uploads, cursor placement between stacked tables. Two genuine features sit at the window's edges: filtered blocks on July 31 and flexible monthly RSS scheduling on August 1. Every entry is titled with its date alone, so the titles carry no signal until rewritten.

AcyMailing vs Buttondown: editorial side-by-side

A
AcyMailing
MKT AUTO
5.0

AcyMailing spent its 11.0 cycle on privacy plumbing and a security rewrite, not features.

◆ Current state

AcyMailing crossed into 11.0 at the end of July, and the release carried a reworked codebase aimed at security plus a GDPR-driven option for handling pixel tracking. The two follow-up patches since have been almost entirely corrective — automations display, followup creation, multilingual campaigns, and restoring the pot file that custom translations depend on. The 10.11 line before it patched an SQL injection and added toggles for IP collection and a statistics recording delay.

◆ Where it's heading

This is a mature self-hosted mailer working through compliance and hardening rather than chasing capability. The consistent thread across both version lines is giving administrators switches for data they previously collected by default — open-tracking pixels, IP addresses on subscription, statistics timing. The rapid 11.0.1 and 11.0.2 patches suggest the codebase rework shook loose regressions the major release did not catch.

◆ Prediction

Expect the 11.0.x patch stream to continue for a few more releases as rework regressions surface, before any new functionality appears. The entries give no signal about what the next feature cycle targets.

B
Buttondown
MKT AUTO
5.0

A near-daily fix stream, with flexible monthly RSS scheduling the only real addition.

◆ Current state

Buttondown publishes a dated entry almost every day, and the overwhelming majority are single bug fixes, several credited by name to the subscriber who reported them. The current window is nine-tenths repair work — stretched newsletter icons in the archive, a portal 403 for subscribers with many accounts, rejected WebP uploads, cursor placement between stacked tables. Two genuine features sit at the window's edges: filtered blocks on July 31 and flexible monthly RSS scheduling on August 1. Every entry is titled with its date alone, so the titles carry no signal until rewritten.

◆ Where it's heading

The shape here is a maintained product rather than one under redirection: the fix stream is dense, specific and largely user-reported, which reads as a small team with an engaged base rather than as instability. The features that do land are narrow gap-fillers — letting a monthly send fall on the 29th, making one section of an email visible to a single audience type — each closing a limitation someone actually hit. Filtered blocks are the only recent change that adds a primitive instead of a setting, since audience-scoped sections are where segmentation inside a single send begins.

◆ Prediction

The likeliest next step is more surface built on filtered blocks, as audience-scoped content is the one recent addition with somewhere further to go. Otherwise the daily fix cadence should simply continue; nothing in this window points to a larger change.
