config server


What is your mind about this server config for 60 customers in mailwizz
VPS Cloud, Virtualisation: 64 Bits VMware® ESXi, Kernel personnalisable, CPU garanti: 6 vCores, RAM garantie: 8 Go, Disque dur: 100 Go Raid 10
Given your example, 60 customers can send 1M emails each at the same time, case in which that server isn't enough.
They can send 1M emails in a day, case in which the server is enough.
You'll have to just go with it and see how it works.

If all those customers will be very active, i'd suggest putting mysql on a separate box and give it as much ram as possible, of course, if this setup is possible for you.
