Server requirements​:
Linux operating system (windows might work but not supported)
Apache Webserver – version 2.x

MySQL(>= 5.1) or MariaDB, with InnoDB storage engine.
Cron Jobs access (linux cron jobs not web crons)

Additional notes​:
While MailWizz works just fine on shared hosting, there might be limitations, thus we suggest using a VPS.
Sending via SMTP will require having php’s proc_open and popen functions enabled.
Mailwizz is designed to work with php >= 5.2 but really, do yourself a good and use php >= 7.0
The availability of some of the app features depends highly on your PHP version, this is why we recommend using at least PHP 7.0
