Great Plugin. Glad I tried something New!
I have previously used the other top 2 SMTP plugins for mail, but I found support not always there, and making things work can be a pain. These guys have been great. The documentation is excellent, and when I did have a question, they answered IMMEDIATELY with a confirmation that they were on it and my issue was resolved in no time at all, which is great as my clients are typically email dependent businesses (aren’t we all).
Highly recommend this plugin.

Post SMTP is very reliable and easy to use
I manage over 150 websites and I can trust Post SMTP to not only get email from the websites where it needs to go, but also send me notifications when something isn’t working. I use it in conjunction with SMTP2go.com as the server. This is a very reliable combination to deliver consistent quality.

I have been using the plugin for many years and no Complaints
I have been using the plugin for many years on multiple websites and it has worked flawlessly. The free version has very powerful features like secure Google API integration for SMTP only access and email logging which helps greatly when troubleshooting email issues. The support is also great and timely!

SMTP like a boss
I discovered this plugin while looking for an alternative to Fluent SMTP, which conflicts with the checkout of a WooCommerce site I manage.
In addition to solving the problem, it opened up a world of amazing features and an unmatched level of control. The notification through an alternative channel when an email delivery fails is also gold.
Clearly the dev knows his stuff. I am considering purchasing a Pro license.

Great Customer Service
I had a very hard problem to diagnose, but Aqib Khan had the skill and tenacity to stick with it until the problem was solve. Hats off to him and the Support Team

Prompt, friendly and accurate.
We have been using the Post SMTP plugin from WP Experts for some time on our website making sure our email messages and notifications get to where they are supposed to! A couple of days ago I needed to locate a copy of an invoice – Aqib’s response to my call for help was prompt, friendly and accurate. Definitely a recommendation!
