Biggest opportunity: Add “smtp plugin”, “logging” and “sendgrid smtp” to your wp.org tags. You rank #7, #8 and #8 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 4 listed these are the slots worth spending.

of downloads still active
At least 60K of 1.2M 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 2 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.

When the plugin is running under PHP8.4, it will cause the website to crash

I’m satisfied with version 1.2.7.The newer updates add unnecessary features.With version 1.2.7, the emails are reliably delivered to the inbox and even marked as important.But with the latest versions, emails often go straight to the spam folder.

Update: 2.1.2 Fixed my issue, Plugin Works as expected Since Version 2.0.0 or Solid Mail rebranding, I have no UI visible anymore and cannot see any Logs or change any settings. Plugin still works tho, but not being able to view Logs and change Settings is not good. Very bad update I must say!! This topic was modified 1 year, 9 months ago by wfrank94.

This plugin was earlier called WP-SMTP and was a simple but perfect working SMTP client in the style of WordPress GPL. Now, it is a non WordPress design conform plugin with an angry fruit salad UI that collects data: “We may collect your name, email address, physical address, and phone number if you provide it to us”. It is now not longer hold by a community member but a company called CloudOne Digital. Say goodbye to freedom of the software and count the days until there is a “pro” or “premium” version.

SMTP Error: Could not authenticate. gmail. It’s not working. I think it’s google crap. When configuring the plugin, it does not display Google’s “approval” window, which in recent years necessarily appears when configuring mail clients. This topic was modified 2 years, 1 month ago by d095614.
