<p>Global SMTP is a utility plugin designed to easily configure SMTP for WordPress by adding a set of constants to your <code>wp-config.php</code> file.</p>
<p>When used with multisite, the configuration is applied network wide. This is often handy to install as a “must use” plugin.</p>


Global SMTP

Works with WP 4.4.2

This is the only SMTP plugin I found that works excellent with Multisite installed WordPress. And supports TLS, SSL, and don't use database and very fast!



Lightweight plugin, Support Multisite

Brevo – Email, SMS, Web Push, Chat, and more.


The plugin is fine if you have one form and don't need any customization. The plugin lacks many options and customization (e.g., there is only Google reCAPTCHA). And you do need bot protection! Without a captcha, you will receive a lot of spam. It also considerably slows down the website. Hopefully, the entire product gets an upgrade.


lacks many options


It's a good system for sending newsletters. The free version allows the graphic creation of newsletter content in an easy and impressive way. Great statistics on openings of emails sent and how many people clicked on the links you put in the emails. I would have put 5 stars but I asked them a question and they didn't answer: newsletters (in the free version) are sent with the sender corresponding to the mail I set in the panel. If many people who receive it put the newsletter in the spam folder, do I run the risk of having my mailbox blacklisted? Why isn't the sender a dummy email so as to prevent this risk (as I have seen other providers do)?


Good system, but...
