Where was this Plugin Yesterday??

What a plugin. The diagnostics and Connectivity Tests gave me the answers I was looking for for so long.. FINALLY got email to work on my site.. Nothing I have about my site seems to be ‘in the box’, and same with Email delivery.. Well, Post SMTP Mailer understood my sites needs over any other similar plugin, so I am happy to tick the BIG LOVE ‘box’ for the plugin

Very Easy to setup

I tried and tried to manually setup SMTP authentication with my Office365/Exchange server. I thought I dotted every “i” and crossed every “t” but I obviously missed something. Using the Office365 Addon was so much faster and easier…saved me a lot of precious time fiddling with settings and researching a solution. I’ve been using the Post SMTP plugin for many years and so glad it’s now a commercial product with continuous development and improvements! Thanks!

Great Plugin, BEST Support

I use this plugin as part of a bundle for all of my new website builds because it works so well. For the first time, I purchased the Add-On for Office 365. I ran into a couple of issues with setup and support worked quickly and efficiently (even did a zoom call) to resolve the problems. HIGHLY recommend and you can feel comfortable that if you purchase PRO or Add-Ons you will be completely support.
