SoloMail is a WordPress plugin designed to email an HTML-formatted copy of a single post to site subscribers or a mailing list. There are quite a few solutions out there designed to send batch digests of recent posts to subscribers on a scheduled basis. SoloMail solves a different problem – you may want to cherry pick just certain posts to go out via email, and you may want the ability to “send now.”
The subscriber list can EITHER be the group of all registered users on a site OR a single address, such as a mailing list. Though you can use SoloMail either way, I recommend sending through a proper mailing list, which provides advantages such as handling and unsubscribing bounced/dead addresses, and metered sending for large lists.

SMTP Mailer

So i have tried configuring it two ways - with gmail and smtp from my own hosting, it doesn't work in both cases.

With gmail it hangs on password authentication according to log - the password IS correct, less secure apps is checked and critical login is confirmed. 

With my own smtp credentials - it supposedly sending test message, but it simply doesn't comply with CF7, there's an error while sending form and that's it.

It is lightweight, which i really like but what of it if plugin doesn't work even on native settings?

To dev:
- if you fix it, then i will change my review. Latest WP, only your plugin and CF7, PHP 7.3 and default Wordpress theme.

It simply doesn't work with CF7

A bloat-free plugin that just sends SMTP emails as advertised. Great job Developers.

Minimalistic, Does the job


This is THE plugin you need to send e-mails. Forget about WPForms, Easy WP SMTP (after their upgrade it got super-bloated) or others. You just need to send e-mails, and this is the plugin to do it. Easy and lightweight.


The #1 SMTP plugin today


In the world of WP plugins, it's easy to get bogged down by bloated, feature-rich options. This plugin is a refreshing departure from that trend. It's lean, mean, and focused on doing one thing exceptionally well: sending emails.


Best SMTP plugin

Configure a SMTP server to send email from your WordPress site. Configure the wp_mail() function to use SMTP instead of the PHP mail() function.
