I love FluentSMTP. I recently emaled their tech support about a connection problem I was having (no emails were getting through), and they were very quick to respond. The issue was resolved in no time. I highly recommend them.

I long time fan of Fluent Products, they keep on providing great tools that just work. Some free and some paid, the SMTP plugin is my GoTo for my site & client work.
My only complain is that the self promotion of the Pro version are a little TOO MUCH and could be toned down and still be effective.

I would love to be able to add affiliate links to the "self promotion" links they use.... now that would be a real win-win!

Just great, not to mention that this is provided for free! Amazing

Truly grateful for the awesome free FluentSMTP Plugin and the phenomenal user support received! Thank you very much FluentSMTP :)

I super appreciate the ease of this add-on, the fact that it has an email log built in, and that I can set up a modern Office 365 email connection for free like this. I'd been putting off updating from legacy SMTP for ages before I finally found this and was able to do it easily.

Working great! Daily reports keeps you up to date if anything gets wrong!

Simple installation and working with no problems

I run WP in docker, which doesn't include any way to send emails. I was going to setup my own SMTP bridge, but I found this plugin which worked great and has continued to work since I set it up.

Brilliant - works perfectly with WP HTML Mail (template for emails)

The customer service is terrific! Quick and intelligent questions and answers! A one and done service.
