Biggest opportunity: Swap “email” and “marketing” for “signup form” and “signup forms”. “email” isn't earning its slot: you're not in the first 24 results for its own search. “signup form” sits at #20 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. “signup forms” sits at #21 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 →2.3%
of downloads still active
At least 60K of 2.6M 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 7 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.

We have been using this for years on a number of sites, but recently we came across a problem that the fields in Mailchimp set up and appearance on the website did not match. Our own fix was being overwritten by plug-in update, so we had to repeat the fix on every website every time we updated the plug-in We reported this to the Author and they came back the next day with a solution. Great support and very happy.

Unfortunately, the lists are full of spam with the update! Very bad. This topic was modified 1 year, 3 months ago by kangei.

The plugin is a complete joke and injects js that is abysmal.

Why has this plugin been abandoned? A company of MailChimp’s size can easily afford to maintain this WordPress plugin. Either support the plugin or delete it.

Doesn’t display anything in a sidebar, no instructions, screenshots look like they’re from 2010 [as @ 22/07/2023].

This plugin does not help you incorporate MailChimp into your WordPress site, at all.
Read on wp.org ↗ - ★★★★★ ericksonstudio4.4y ago
If you have PHP version 8.0 or above on your website, you will receive the following message ONLY if you have the Javascript option OFF in the MailChimp plugin settings — if you don’t have the Javascript option on, the form won’t work and you won’t receiving any error messages indicating why: Warning: Undefined array key “phone_format” in …/wp-content/plugins/mailchimp/mailchimp.php on line 861 Downgrade to PHP 7.4+ if possible and it will work again. In the meantime, MailChimp really needs to up their game since WordPress+MailChimp integration is important to many, otherwise you’ll telling us to move to Constant Contact, et cetera.
