Just simply NOT working
It looses the api key, one it was working and the mails were sent, then no way to make it work again.... I ave several accounts in mailgun... Sometomes only the sand bow appears, sometimes the other appear !!!! Incredebly unstable !

Mailgun gives cron lock
Every time I switch over to mailgun plugin I get Cron Lock. All parameter have to be so low that it's hopeless to use this. I have to set the number of email to 20 and 150ms between each and then is's working for 2 or 3 cycles. I use cron job on siteground to run the job and this is configured to run every 30 min. So my newsletter use 2-3 weeks to get out. I never gets cron lock when using simple smtp.

USE Post SMTP Mailer/Email Log
This plugin have some serious flaw, I tried everything using this plug in, it won't complete my email delivery list. This error kept on appearing: ‘to’ parameter is not a valid address. please check documentation. The worst of it, it doesn't have email log funchtion, so I could not know what went wrong, I suspect it was a bug in the software, using Post SMTP Mailer/Email Log solved all of my problems and it also had email log function, If there is any errors in the future, I could easily track it.

Use WP SMTP
I have tried this plugin, and set everything right in Mailgun itself. I was keep getting the following error: 'to' parameter is not a valid address. please check documentation. While searching long for as solution, I tried WP SMTP, and the error was gone and my campaign was sending again.
