Upgraded to resolve an issue that did not actually require the upgrade as it was unrelated. This was essentially my guess work. Went to cancel and was given a refund. I will use them when I need to grow direct emails from site again

As I have been building my new sites, I have looked for a plugin that would work on my multisite network. Post SMTP does! But somewhere along the way, I made a newbie mistake and couldn't fix it. No problem! Mubashir talked me through some possibilities, but when I just couldn't get it working again, he did. He was so patient, waiting until I understood one thing before giving me any other thoughts. I may be a newbie, but I made the right choice in Post SMTP.

I am a beginner and I needed to update our PHP on our website. The checker said (wrongly) this was not compatible with the Post SMTP plugin - I reached out to the company and they were great and said that they're fully compatible with all PHP versions. Very helpful and responsive.

Outstanding support and I'm on the free version! I got an error notice from Post SMTP but there were no errors in the smtp log. I asked the plugin authors for support. They explained the error to me, and why it was not showing in the report. This gave me the ability to gather recent web form entries and give them to the site owner as she might have missed some email deliveries. I never would have known were it not for this plugin and the support I received. 10/10 recommend.

After purchasing PostSMTP Pro and facing some incompatibility issues with other plugins I asked for help and I was impressed by the awesome and rapid support given by M Aqib Khan to solve the issue. Great thanks! I highly recommend this plugin.

Post SMTP is hands-down the best of its kind in the Wordpress world. I have been using for years for all my websites. But today I want to say HUGE THANKS to Mr. Aqib Khan for your prompt and excellent support helping me work out the error code that I was receiving. So, in short, top-notch plugin with the best customer support behind it!
