Biggest opportunity: Swap “email signup” for “top”. “email signup” isn't earning its slot: it only gets you to #12. “top” sits at #6 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 →1.5%
of downloads still active
At least 6K of 388.1K lifetime downloads are still running, above 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 5 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.

What to do about it
- Swap “email signup” for “top”. “email signup” isn't earning its slot: it only gets you to #12. “top” sits at #6 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “email signup”. #12 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

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.

the plugin is displayed in “plugins” but no menu, no settings, completely useless … it is useless!

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

You can customize the colors and the appearance.

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.
