Kaddora MailFlow SMTP

Ownership

Held by kaddora throughout, with no change of ownership observed since daily tracking began on 30 Aug 2026.

Full observed history, including every field transition

Committing accounts

Read from the plugin’s public release log, so these predate this registry. A committing account is not an owner. Thirty accounts commit to WooCommerce and it has never changed hands.

This registry did not observe a transfer; it read these names off a public log. Whether that reflects a change of ownership is not something the directory publishes.

Adoption

How widely the plugin is installed, and what the people running it think of it. WordPress.org rounds install figures to one significant digit, so they describe an order of magnitude rather than a headcount.

Very early-stage: 40+ active installs. Too few installs to read anything into adoption. That is a gap in the evidence, not a mark against the plugin.

4 downloads a day averaged over 9 days. WordPress.org reports a running download total; the gap between two days is that day’s downloads. Unlike the install figure it is exact and has no ceiling, so it shows movement the rounded band cannot. Too few days so far to say whether it is rising or falling.

Install band rose to 40+ on 31 Aug 2026, from 30+. Both figures are rounded to one significant digit, so the size of the change is not knowable from them.

Every field we record, one column per observation. Fields that never moved are named once rather than repeated across every column. A row of identical numbers would be padding.

Unchanged throughout: ratings total (0) · version (1.0.0) · support threads (0) · threads resolved (0)

Everything dated that this registry holds about the plugin, most recent first. Releases carry the author’s own release date; everything else is dated to when it was observed.

What we know, and what we don’t

Everything on this page in one place, including the gaps, so that nothing here is mistaken for a clean bill of health.

Every record on this site, this one included, works under the same limits. We read what WordPress.org publishes about a plugin, never the plugin’s own code, so nothing here says whether a plugin is well built or safe. Install counts reach us already rounded; a change smaller than a band step doesn’t show. We don’t track security advisories yet. For anything older than our first observation we rely on the plugin’s public release log, where one exists. What this registry can and cannot see

Similar plugins

Plugins that share this one’s tags and talk about the same things in their own descriptions. Distinctive tags count for far more than broad ones. Sharing hover means something, sharing woocommerce does not, and a plugin that never mentions the subject matter is left out however its author tagged it. Among close matches, more widely installed plugins are listed first. This is a grouping rather than a ranking of quality.
