MC4WP: Mailchimp Top Bar – Email Subscribe Notification Bar

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 · 73% 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. The recent download trend is too spiky to read.

   The Support staff are not interested in helping you, just marking their Topics as ‘Resolved’. You need to Hire a WordPress Developer if you want to get the full functionality from the ‘add-on’. I’ve spent 4 days wasting my time on this plugin and will never ever install this rubbish again. I’d give it 0/10 if i could.

   This useful topbar does need to be updated to allow a required checkbox otherwise it’s no longer useful/legal to use on any website within the EU or any website collecting data from EU citizens. This topic was modified 6 years ago by mykilos.

   Hi, I just installed MailChimp Top Bar on my website (where it became a Bottom Bar), and it works just great. Setup is hassle-free, and it looks great without being too aggressive. https://www.microlinux.fr Cheers, Niki

   This is problably the simplest way for adding a MailChimp subscription form to a website – and it’s very effective in terms of conversions. Integrates nicely with the popular MailChimp für WordPress plug-in from the same developers.
