What is EmailEngine?

EmailEngine is a headless email client. It connects to IMAP and SMTP mailboxes and gives your application one REST API to read, search and send mail, plus webhooks that tell you when new mail arrives or a delivery event happens.

It is source-available rather than free open source: it runs on a 14-day trial, then needs a licence key bought from its maintainers. Here the admin UI and REST API sit on one HTTPS domain, with a password-protected Redis beside them holding accounts, tokens and settings on your own server.

From Sign-Up to Your First Mailbox In Just 3 Easy Steps

An EmailEngine stack normally means the app, a Redis kept from evicting data, a secret, a domain and a certificate before the first API call. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick EmailEngine from the OneClick catalog. Choose your domain and target server — there are no extra fields to fill in.
Step 02
We Deploy It For You
One click. We bring up EmailEngine with a private, password-protected Redis 7.4 that has no public port, mount the redis_data volume, generate the admin password and secret, and publish the admin UI and REST API over HTTPS on your domain.
Step 03
Create A Token, Add A Mailbox
Save the Admin Password from the protected installation credentials, open your HTTPS URL and sign in as admin. Click Start a 14-day trial on the dashboard, create an API access token, then add your first mailbox.

Everything EmailEngine Does, On Your Own Server

EmailEngine runs in full here: an email gateway with an admin UI on your own domain, backed by a Redis you own.

Mailboxes Through One REST API
Read, search and send mail for connected IMAP and SMTP mailboxes through one REST API.
Webhooks
Get webhooks for new mail and delivery events, so your application reacts without polling.
Optional SMTP And IMAP Proxy
An SMTP submission server (port 2525) and an IMAP proxy (port 9993) are published on the host but stay off until you enable them in the admin UI.
Admin UI And Access Tokens
Sign in to the admin UI and create API access tokens; calls without a token are rejected with 401.
Generated Admin Password
The admin password is generated and applied from the first boot, and wrong passwords are rejected.
Private Redis Storage
Accounts, tokens, settings and queues live in a bundled password-protected Redis with no public port, on the persistent redis_data volume.

Work with a dedicated support inbox
Attach one mailbox, such as a support address, to your own software and process its messages through the API.
Keep mailbox credentials and tokens on your own server
Hold accounts, API access tokens, settings and queues in a Redis volume you control.

EmailEngine vs Alternatives

Nylas: A hosted commercial email and calendar API; EmailEngine runs on a server you control, with its data in your own Redis.
Mailgun: A hosted service for sending and receiving transactional email; EmailEngine instead connects to existing IMAP and SMTP mailboxes and exposes them through a REST API.
Roundcube Webmail: A browser mailbox client for people; EmailEngine is headless and gives your software the mailbox through an API.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

xCloud gave me what no other hosting platform could: the flexibility of a VPS with the convenience of managed WordPress. As a solo founder running an entire business on one server, that combination is an important unfair advantage.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

How do I sign in?

Use admin and the generated Admin Password from the protected installation credentials card. Wrong passwords are rejected, and API calls without an access token return 401.

What runs alongside EmailEngine?

A private Redis 7.4 that stores all EmailEngine data. It has a password and no public port; the admin UI and REST API are published over xCloud-managed HTTPS.

Is it free?

No. EmailEngine is source-available under the EmailEngine License. It runs on a 14-day free trial, then needs a licence key purchased from EmailEngine (postalsys.com) and entered in its settings. Until a trial or licence is active it stops syncing accounts shortly after each start.

Are the SMTP and IMAP proxy servers on?

No. The SMTP submission server (2525) and IMAP proxy (9993) ports are published on the host but stay off until you enable them in the admin UI, and you open your own firewall if you need them reachable.

What should I back up?

The redis_data volume, which holds accounts, tokens, settings and queues, and the stable .env values. Never change EENGINE_SECRET after accounts are added, and treat the admin password, API tokens and EENGINE_SECRET as secrets.

Backups in xCloud

What survives a restart?

Accounts, tokens, settings and queues live on the persistent redis_data volume, and an added account was still listed after an xCloud Restart in QA.

Does xCloud automatically back up or update EmailEngine?

No. The template pins EmailEngine v2.83.2 by immutable digest; new installations use the pinned release, existing sites are not automatically upgraded. Back up first, read the upstream release notes, then bump the readable tag and digest together on your own schedule. Server-level backups and snapshots are available on every Cloud VPS.

What are the server requirements, and why does this page sell 6 GB?

The template's baseline asks for 2 CPU cores, 1024 MB of RAM and 5 GB of disk; measured use in QA was about 700 MB. This page sells the 6 GB tier as the entry rung, with real headroom above that baseline.

Is xCloud officially partnered with EmailEngine?

No. No official partnership or endorsement between xCloud and the EmailEngine project has been verified. This is a deployment and server-management option for EmailEngine, which is licensed by its maintainers.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
