Keap Official Opt-in Forms

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 56% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

   After the Bloom opt-in functionality stopped supporting Keap (because of sunsetting the legacy APIs), I started using the Keap plugin. As far as getting people who opt-in into Keap it works, but it doesn’t have very many features. The feature I’m most missing is the ability to append email and name parameters from a submission to a thank you page redirect. This makes initiating a tripwire/deadline offer not possible directly from a submission. Keap, please add this functionality.

   Such a large organization should be embarrassed by such a terrible plugin. None of the API keys will connect, support won’t help.

   The plugin used to work ok, but often crashed loading the backend due to a huge amount of stats data. There is no way to store stats for xx amount of time then delete older than a set date or amount of days. The plugin was effectively dead for pretty much 1 whole year as the code-base contained vulnetabilities, so much so that wordpress.org prevented download of the plugin. Now finally an update has been released that addresses the code vulnerabilities, however when connecting to my Keap CRM, I found that it will only authorize using the legacy API key (not a server key or personal access key). The problem here is that Keap will retire legacy API keys in October 2024 (for existing keys), which is only a few months away. Therefore the plugin will no longer work after this date without a further update to the plugin. Overall when it works, it works. It’s a little inflexible in the data that can be catptured, only the name and email are options. As the plugin stopped working due to vulnerabilities for a long time, I have already replaced the functionality and updated my keap CRM automations; and improved upon the fields that are captured with an alternative. I cannot see myself using this plugin any further and trying the recent update is my last attempt to revive it.

   Aside from the many other issues, the forms created by this plugin are extremely inaccessible. It’s responsible for every single error reported by the WAVE browser extension on a client site.
