Biggest opportunity: Swap “email”, “mailchimp” and “smtp” for “emails”, “change mail sender name” and “email service”. “email” isn't earning its slot: you're not in the first 24 results for its own search. “emails” sits at #10 untagged, close enough for a declared tag to move it up. “mailchimp” isn't earning its slot: you're not in the first 24 results for its own search. “change mail sender name” sits at #13 untagged, close enough for a declared tag to move it up. “smtp” isn't earning its slot: you're not in the first 24 results for its own search. “email service” sits at #15 untagged, close enough for a declared tag to move it up.

How it's measured →2.2%
of downloads still active
At least 6K of 269.2K lifetime downloads are still running, above its category: the median Email & Marketing plugin keeps 0.9%, across 1,294 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 15 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 haven’t had any issues with the plug-in and it’s sending hundreds of emails every week for our woocommerce website for the last year.

I am very happy with it, using it on 150 sites.

I had trouble integrating Mandrill manually, but this plugin was a fantastic find. Despite my initial concerns about its lack of recent updates and a small support team, I’m happy to report that it worked perfectly. I highly recommend this plugin for Mandrill setup—it’s easy to use and flawlessly effective.

And it’s still supported by the developers unlike the old one

Great that this plugin got a second life! It beats tons of other SMTP plugins trying to support mandrill. It needs a few updates to be fully PHP7.4 compatible and it would be great to have a few extra options (thing return_path_domain etc). On that note: I can help if that would in this great effort!?

Thank you for taking the initiative to fork the unsupported plugin and get it working with modern PHP.

The old unsupported Mandrill app had begun causing errors on our website. It caused issues with our WooCommerce installation. Luckily we found this plugin just in time to fix all of our problems. Thank you! Thank you!
