Biggest opportunity: Swap “smtp”, “wordpress email” and “wp mail smtp” for “welcome”, “email logging” and “outgoing email”. “smtp” isn't earning its slot: you're not in the first 24 results for its own search. “welcome” sits at #4 untagged, close enough for a declared tag to move it up. “wordpress email” isn't earning its slot: you're not in the first 24 results for its own search. “email logging” sits at #17 untagged, close enough for a declared tag to move it up. “wp mail smtp” isn't earning its slot: you're not in the first 24 results for its own search. “outgoing email” sits at #18 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

2.0%

of downloads still active

At least 7K of 345.5K 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 1 release 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.

    The idea of this plugin is really great.But unfortunately t goes to scr*w up the link/email/page of the lost password.So that when a user forgets the password will be never ever able to get the change password form. Only the login form is showing up.

    This plugin is super easy to use and connect to whatever email service you are already using. Much better than the built-in / server-side emails that WordPress defaults to. Thank you <3

    This was just what is was looking for. I have a client portal system within a CRM. The registration process for user involved them getting the standard WP password reset email which is messy. I was easily able to change the wording to suite my requirements. Thanks so much for your work on this great plug in.

    After doing some research about how to customize the new user welcome email, I was going to dig in and setup my own plugin. I found this plugin before I started and saved myself a good chunk of time–and it’s probably exactly what I would have created myself. Simple, perfect and allow me to do what I need to do (removed the login url and added some images and my own copy to the email). Thank you for publishing this so the rest of us can use it, too! FYI – if this isn’t working for you, you probably have theme or plugin conflicts. This is a very simple plugin.
