MailWizz itself is just a PHP application — the sending performance and deliverability come almost entirely from the server it runs on. That means outbound Port 25 access (or a working relay), a dedicated IP with clean reputation, correctly configured cron jobs for the delivery queue, and enough MySQL performance to handle segmentation across large lists.
A VPS with full root access lets you tune PHP, MySQL and your chosen delivery server (Postfix, PowerMTA, Amazon SES, or another SMTP relay) exactly to MailWizz's requirements, instead of working around a shared hosting panel's limitations.
The infrastructure pieces MailWizz depends on, covered by default.
Send directly from the server without routing through a third-party relay, if your workflow prefers that.
Your MailWizz sending reputation is not shared with unrelated tenants.
Match your reverse DNS to your sending domain for stronger authentication.
Faster MySQL queries when segmenting and filtering large subscriber lists.
Install MailWizz on your own LEMP/LAMP stack and tune PHP and MySQL for its workload.
Upgrade CPU, RAM and storage as your subscriber count and send volume grow.
Port 25 and dedicated IPv4 are standard, not a special upgrade tier for email use cases.
Install MailWizz, cron jobs and your preferred delivery server without a managed panel getting in the way.
Start on a smaller plan and move up as your MailWizz list size increases.
Our plans are unmanaged, so you install MailWizz yourself on the LEMP/LAMP stack of your choice; our team can help with deployment questions.
It depends on your list size and send volume; Standard or Advanced suits most MailWizz installations, with Pro for larger lists.
