What is the maximum emails newsletterplugin can send per hour?
our configuration (planned, yet to implement)
1. SMTP server is will be running in a cluster (4 nodes, 4cpu, 12GB per node)
2. WordPress server (4 cpu , 20gb RAM)
3. 1 Gbps fibre lines
4. Newsletter size max 100kb
No restrictions from ISP and our IP is whitelisted and has rDNS
We want to achieve at least 250,000 emails per hour. Is it possible to do?
