Is this page just an advert for your hosting?

Partly, and it says so. The checklist is written to be useful whoever you buy from — the requirements are the software vendor's, not ours. Three lines in the table answer No for us, including backups and managed setup, because a checklist that scored us full marks would be worthless to you.

What single thing disqualifies a host fastest?

Blocked outbound Port 25 with no route to having it opened. Most large cloud providers block it by default: AWS requires a written request that can be refused, and Google Cloud blocks connections to external port 25 with no unblock path at all. If you intend to deliver mail yourself, that ends the conversation.

Do you hold a backup of my subscriber list?

No, on any plan, at any price. We hold no copy of your data at all. A subscriber database is exactly the thing you cannot afford to lose, so set up your own off-site backup before your first import.

Will you install and configure it for me?

No. Every plan is unmanaged. Support answers platform and network questions and sets your reverse DNS, but does not install your stack, tune your database or debug your sending. If you want that, you want a managed provider, and we would rather say so than take the order.

How do I know a provider will not change its mind about Port 25?

You do not, entirely — read the acceptable use policy rather than the sales page, since that is the document that governs. Ours allows opt-in marketing and transactional mail and says plainly that repeated blacklisting or high complaint rates can get sending disabled on the affected server.

Which plan should I actually pick?

Start from the software's published requirements rather than from a price. The suggested plan on this page is derived from them, and the product page for this software explains the reasoning in more detail.

Is Port 25 guaranteed on every plan, or just open?

Both, depending on the range, and the difference is worth knowing before you buy. Outbound Port 25 is open by default on all 16 plans — no ticket, no approval step. On NVMe VPS, Cloud VPS, Classic VPS and VDS it is written into the published plan specification. On it is open because of how the network is run rather than as a documented guarantee. In practice it behaves the same on all of them, but if your business stops when you cannot send, buy the range that puts it in writing.

MailWizz · Choosing a Host

You have picked MailWizz. Now vet the host.

MailWizz will install almost anywhere with PHP and MySQL. Whether it can actually deliver depends entirely on things the host controls, and most hosting pages never mention them. Here is what to check, including the questions we would rather you asked us.

The Checklist Questions to Ask

Things that disqualify a host

Port 25 blocked · shared IP · no custom rDNS

Port 25 open with no ticket
Dedicated IPv4 on every plan
Custom rDNS set free on request
We do not resell MailWizz licences

The Short Version

MailWizz itself is undemanding — an ordinary Linux, PHP, MySQL and cron stack. What decides whether your campaigns land is the network underneath it: whether outbound Port 25 is open without an application, whether the IPv4 address is yours alone, and whether the provider will set a reverse DNS record to match your sending hostname. A host that fails any of those three cannot run MailWizz properly no matter how much CPU it sells you. Everything else is comfort.

Non-negotiable: outbound Port 25, a dedicated IPv4, and custom rDNS.
Software stack: Linux, PHP, MySQL and cron — any competent VPS host can do this.
Licence: $89 Regular, or $275 Extended if you charge customers for access.
Delivery: MailWizz sends through delivery servers you configure, not by itself.
Sizing: segmentation and reporting are database work — memory and storage speed first.
Ask before paying: is Port 25 open today, or after a review?

What to Demand From Any Host

The requirements come from the software vendor; the verdicts are ours and are answered straight. Where the answer is no, it is no.

Requirement	Why it matters	Us
Outbound Port 25, open now	MailWizz can use a relay, but if you want your own SMTP server to be one of its delivery servers, Port 25 has to be open. Many hosts block it and some never unblock it.	Yes Open by default on every plan, no approval step
A dedicated IPv4 address	Sending reputation attaches to the IP. On a shared address you inherit the behaviour of everyone else using it, and you cannot set a meaningful PTR record.	Yes Included on all plans, no extra charge
Custom reverse DNS	Receiving servers check that the PTR record matches your sending hostname. Only the IP owner can set it, so a host that will not do this is a hard blocker.	Yes Set by support on request, free
Root access	MailWizz needs cron, specific PHP settings and often a local MTA. A managed panel that restricts these gets in the way.	Yes Every plan is unmanaged, full root
Fast storage for the database	Segmenting a large list and building campaign reports are read-heavy database operations. This is what you feel as the list grows, long before CPU matters.	Yes Enterprise SSD and NVMe ranges available
Additional IPv4 addresses	Useful once you want to separate traffic types or rotate sending addresses. Worth asking about before you commit rather than after.	Yes Available — ask support for current options
IPv6	Rarely essential for sending, since most receiving infrastructure still prefers IPv4, but worth knowing if your stack expects it.	Depends Varies by datacenter — ask about your location
Managed setup and tuning	Some senders want the host to install and configure the stack. That is a legitimate requirement, and it is not what we sell.	No All plans unmanaged; support covers platform, not your MTA
Backups of your subscriber list	A subscriber database is the one thing you genuinely cannot lose. Check who is responsible before you import anything.	No We hold no copy of your data on any plan — set up your own

Four Questions Worth Asking Before You Pay

Ask any provider, including us. The answers are more revealing than a feature list, and a vague reply is itself an answer.

“Is outbound Port 25 open right now, or after a review?” “Available on request” can mean a form, a wait and a refusal. Ask for a straight answer before you pay. Ask
“Will you set a PTR record to a hostname I choose?” Some hosts only offer a generic hostname, or charge for a custom one. Ask what the actual process and turnaround is. Ask
“Is the IPv4 address mine alone?” “Dedicated IP” is sometimes an upsell rather than a default. Confirm it, and confirm whether it costs extra. Ask
“What happens if I get blacklisted?” A useful question because the answer tells you how the provider treats senders in trouble — and whether they will simply null-route you. Ask

We would rather answer these before you order than refund you afterwards. Ask us directly →
