What is the single most important thing?

Outbound Port 25 open without an application process. Everything else on the checklist can be worked around or bought later; this one cannot. Most large cloud providers block it, which is why people end up looking at smaller hosts for bulk sending.

How big a plan do I need for bulk email?

Smaller than you would guess for the mail server, larger than you would guess for the campaign software. An MTA relaying to the internet spends its time waiting, not computing. Segmenting a large list and building reports is database work, and that is what actually needs memory and fast storage.

Can I send bulk email from the cheapest plan?

Technically yes, and it is a false economy for a real list. The entry plan has 1 core, 1 GB of RAM, 15 GB SAS, 1 Gbps port. It will run a mail server; it will struggle with campaign software over a large subscriber database.

Which software should I run?

That depends on whether you want campaign management, delivery, or both — and four of the six popular packages cannot send mail at all on their own. Mautic and listmonk are free; Postal is free and delivers mail itself; MailWizz and Sendy are commercial; PowerMTA is commercial and quote-priced.

Do you help with deliverability?

No, and it would be dishonest to imply otherwise. Every plan is unmanaged. Support answers platform and network questions and sets your reverse DNS, but nobody here will read your bounce logs or advise on why a provider is deferring you.

Is bulk email even allowed?

Opt-in bulk email is, and it is much of what these plans are for. Purchased, scraped or rented lists are not, and are the fastest route to having sending disabled on your server. The policy exists because one abusive sender damages the network reputation every other customer depends on.

Would a relay be better?

For a lot of senders, yes. A relay lends you an established reputation and handles warm-up, blocklists and bounces. You pay per message and give up control. If your volume is modest or nobody wants to own deliverability, that is the better trade.

What is the best VPS for bulk email?

One that leaves outbound Port 25 open without a ticket, sets no low sending cap, gives you a dedicated IPv4 with a PTR record you choose, and permits opt-in bulk email in its acceptable-use policy. Most large clouds block Port 25; Contabo leaves it open but documents about 25 emails a minute, and Hostinger 5. VPS For Life meets all four on every plan, from $4.95 a month.

How many emails a day can a bulk email VPS send?

Two limits apply. The host's cap, if it has one: about 25 a minute (at most 36,000 a day) at Contabo and 5 a minute (7,200 a day) at Hostinger; our terms set none. And your IP reputation, which is the one that binds on a new server: receiving providers throttle an unknown IP, so daily volume has to be built up over weeks.

Do I need ID verification to run a bulk mailing server here?

No. There is no ID, KYC or phone verification at any order value, and Port 25 is open from deployment, so there is no unblock request to justify. What is enforced is how you send: opt-in lists, working unsubscribes, and nothing that gets the IP blacklisted.

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.

Bulk Email VPS · Choosing a Host

Best VPS for bulk email: three non-negotiables, and one thing no host can sell you.

For bulk sending, a host has to give you open Port 25, an IP address that is yours alone, and reverse DNS you can point at your own hostname. Miss any of the three and the rest of the specification does not matter. The thing nobody can sell you is a warm IP — that one you earn.

Bulk Email Hosting, in One Paragraph

A host can give you exactly three things that matter for bulk sending: outbound Port 25 open without an application, an IPv4 address nobody else uses, and a reverse DNS record you choose. Most large cloud providers fail the first — AWS blocks port 25 to the internet until you request removal, and Google Cloud blocks it to external destinations with no unblock path at all. Some hosts that pass it then cap how fast you can send, which for a bulk sender is the same problem arriving later. Everything else on a hosting page is comfort: more cores, more memory and faster disks help your campaign software and its database, not your delivery rate. What genuinely determines how much mail lands is your IP reputation and your list quality, and no provider can sell you either.

Non-negotiable: Port 25 open, dedicated IPv4, custom rDNS.
Also check: inbound SMTP unfiltered, so bounces and feedback loops reach you.
Buy capacity for the database, not for the mail server.
Read the acceptable use policy, not the sales page.
Nobody sells a warm IP — warm-up is weeks of careful sending, on a schedule like this one.
Opt-in only. A purchased list ends a new IP in one campaign.

What to Demand From Any Host

Thirteen things worth checking with any provider. Three of our answers are no, and one is “it depends” — a checklist where the author scores full marks is an advert, not a checklist.

Requirement	Why it matters	Us
Outbound Port 25, open without an application	Bulk sending from your own server is impossible without it. AWS blocks it to the internet until you request removal; Google Cloud blocks it to external destinations with no unblock path at all. This single item eliminates most large providers.	Yes Open by default on all 16 plans, no ticket
No low per-minute sending cap	Some hosts that leave Port 25 open then limit how fast you send — Contabo documents about 25 emails a minute, Hostinger 5. At 5 a minute a 50,000-address list takes about a week. Find the number before you migrate.	Yes No per-minute or per-day cap in our terms
A dedicated IPv4 address	Sending reputation attaches to the IP. Share one and you inherit every other tenant's behaviour, and you cannot set a meaningful PTR record.	Yes Included on every plan, no surcharge
Custom reverse DNS	Receiving servers check the PTR matches your sending hostname. Only the address owner can set it, so a host that will not is a hard stop.	Yes Set by support on request, free
Inbound SMTP unfiltered	Bounce processing and feedback loops need to reach you. A provider that filters inbound mail quietly breaks your bounce handling.	Yes Nothing filtered at our end
Additional IPv4 addresses	Needed once you separate transactional from marketing traffic, or rotate sending addresses. Ask about availability before you commit.	Yes Available — ask support for current options
Root access	You will be installing an MTA, tuning it, and running cron. A restrictive managed panel gets in the way of all three.	Yes Every plan unmanaged, full root
An acceptable use policy you can live with	Some hosts open Port 25 and then object when you use it. Read the policy, not the sales page — that is the document that governs.	Yes Opt-in marketing and transactional mail permitted; abuse gets sending disabled
Fast storage	Segmenting large lists and building campaign reports are database work. This is where slow disks show up, long before the MTA notices.	Yes NVMe on NVMe VPS, Cloud VPS and VDS
IPv6	Rarely needed for sending, since most receiving infrastructure still prefers IPv4, but some stacks expect it.	Depends Varies by datacenter — ask about your location
Backups of your subscriber database	The one thing you genuinely cannot re-create. Establish who is responsible before your first import.	No We hold no copy of your data on any plan
Deliverability support	Somebody who will look at your bounce logs and tell you why Gmail is deferring you. That is a real service and it is not hosting.	No Unmanaged — support covers platform and network, not your sending
A warm IP on day one	No host can sell you this. A new address is unknown to receiving providers, which means throttled until you have earned otherwise.	No Nobody can provide this — a relay lends you theirs instead

VPS Servers for Bulk Mailing, Compared

Port 25 first, then the sending cap — the two things that decide whether a host can carry bulk mail at all. Each competitor row comes from that provider's own documentation, checked 10 October 2026.

Outbound Port 25 policy and documented sending caps at hosts compared for bulk email, checked 10 October 2026
Host	Port 25	Sending cap	What it takes	Source
VPS For Life	Open by default	No cap in our terms	Outbound port 25 is open on every plan from the moment the server is deployed. No ticket, no approval step, no waiting period, no minimum account age and no identity check. Custom rDNS/PTR on request, on IPv4 and IPv6.	Our Port 25 page
Contabo	Open, with a rate limit	25/min ≈ 36,000/day max	Contabo documents no outbound port 25 block — its firewall documentation says outbound traffic is unrestricted — and its support KB sets a sending limit of about 25 emails per minute, warning that regularly sending above it may get the server throttled.	Contabo support KB
Hostinger	Open, 5 emails a minute	5/min ≈ 7,200/day max	Hostinger's VPS help article says it does not block port 25, and that sending is capped at 5 emails per minute to prevent abuse. If port 25 will not connect, it points you at your own VPS firewall rules first.	Hostinger help
OVHcloud	Open, under anti-spam watch	None published	OVHcloud's mail-sending guide says outgoing port 25 is not blocked by default on VPS or dedicated servers, but its anti-spam system may block it at network level if spam is detected from your IP. VPS deployed in Local Zones cannot reach SMTP servers at all.	OVHcloud docs
Vultr	Blocked, lifted on request	Port 25 blocked first	Vultr blocks outbound port 25 by default. Their documentation says the block may be removed by opening a support ticket.	Vultr docs
AWS EC2	Blocked to the internet, lifted on request	Port 25 blocked first	By default EC2 allows outbound port 25 only to private IPv4 addresses; traffic to public IPv4 and IPv6 addresses is blocked. AWS documents a request to have the restriction removed.	AWS EC2 docs
Hetzner Cloud	Blocked, then case-by-case	Port 25 blocked first	Hetzner blocks ports 25 and 465 by default on all cloud servers. Their docs say you may submit a limit request once you have been a customer for a month and paid your first invoice, and that decisions are made case by case. Port 587 is not blocked.	Hetzner Cloud FAQ
DigitalOcean	Blocked, no published route	Port 25 blocked first	Ports 25, 465 and 587 are blocked on Droplets. DigitalOcean's documentation describes no process for unblocking them and instead recommends against running your own mail server, pointing users to third-party email services.	DigitalOcean docs
Google Cloud (Compute Engine)	Blocked, no self-service route	Port 25 blocked first	Connections to destination port 25 are blocked when the destination is outside your VPC network. Google notes some projects do not carry the restriction, but documents no self-service way to have it removed, and recommends ports 465 or 587 through a third-party relay instead.	Google Cloud docs

“Per day” is the documented per-minute cap times 1,440, the most the host would allow if you sent around the clock. Your real ceiling on a new IP is lower: it is set by receiving providers, not by the host. All 16 hosts: which VPS providers allow Port 25 →

Four Questions Worth Asking Before You Pay

Ask any provider, including us. A vague answer is itself an answer.

“Is outbound Port 25 open today, without a request?” “Available on request” can mean a form, a delay and a refusal. Get a straight answer before paying. Ask
“Will you set a PTR record to a hostname I choose, and how fast?” Some hosts offer only a generic hostname, or charge. Turnaround matters because you cannot send properly until it is done. Ask
“What does your acceptable use policy say about sustained volume?” This is where a disagreement will happen if one happens. Read the policy itself. Ask
“What happens if my IP gets blacklisted?” The answer tells you whether they will help you delist or simply null-route you and close the ticket. Ask

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