Biggest opportunity: Swap “email”, “marketing” and “optin” for “lead generation”, “generation” and “internet marketing”. “email” isn't earning its slot: you're not in the first 24 results for its own search. “lead generation” sits at #9 untagged, close enough for a declared tag to move it up. “marketing” isn't earning its slot: you're not in the first 24 results for its own search. “generation” sits at #13 untagged, close enough for a declared tag to move it up. “optin” isn't earning its slot: you're not in the first 24 results for its own search. “internet marketing” sits at #15 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →1.0%
of downloads still active
At least 2K of 198.4K lifetime downloads are still running, in line with its category: the median Email & Marketing plugin keeps 0.9%, across 1,295 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Email & Marketing plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 4 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

Works without problem. Simple configuration.

I installed the plugin and when trying to create my first popup I got the following error: “We could not load the editor because the defined template is no longer available.” I can’t create any popups. Very disappointing, I really wanted to try this.

I was looking for something lightweight, simple, and, with an intuitive real-time interface for my client. This met the requirements. Here are some sugestions for improvement, though. Adding a template with a picture and button. Now, the only templates with pictures are the ones with sign-up forms. Adding an option to set a lifetime of a cookie when the modal window is closed, including a session cookie for example. Adding an option to open a link assigned to a button in a new window. Don’t load styles when no window is active. It can be simply done by checking whether any post of hollerbox type is published.

I was hoping that this plugin was good… Luckily I only installed it on my staging page. That page got permanently spammed by a message that says “Attention: It looks like MailHawk is installed but is not connected to the MailHawk service.” I don’t have Mail Hawk and I don’t want it. But this message appears on top of all my sites in the admin area now, even after deleting the holler box plugin. Thankfully I can just renew my staging page and the spamming is over. But that’s real shady business!

Garbage plugin, installed on 10 websites, after an update all popups stopped working. When I try to edit it says “We could not load the editor because the defined template is no longer available.”
Read on wp.org ↗ - ★★★★★ hikingdog4.2y ago
No. The software was riddled with bugs and modal popups that would display when the code threw an error. Really amateurish. I got a refund.
Read on wp.org ↗ - ★★★★★ miheui5.8y ago
Popup won’t hide even if the user clicks the “X” button. I have it set to hide if the user hides it. I absolutely HATE popups that won’t go away. And this one also doesn’t stop showing if I refresh, despite that the setting is not to activate until after 5 days.
