If you’ve lived in Aotearoa for a while, you’ve seen it: that tidy @xtra.co.nz at the end of an email address. The xtra name has been part of New Zealand’s internet story since dial-up, and plenty of people and small businesses still rely on it every day. This guide explains what xtra email is, how it runs today, the best way to set it up, and when it’s the right choice for you.
You’ll find clear steps for configuring devices, a quick comparison of IMAP vs POP, practical pros and cons, and answers to common questions Kiwis ask about xtra.
What is
What is xtra in New Zealand?
Xtra is Spark New Zealand’s long-running email service that uses @xtra.co.nz addresses. It began life in the 1990s under Telecom New Zealand’s “Xtra” internet brand and has carried on through the company’s evolution into Spark. Many households and sole traders still use xtra email as their primary inbox—often because the address is well known to friends, family, and customers.
For many years, xtra email was hosted by Yahoo as part of a portal called Yahoo!Xtra. In 2017, Spark moved xtra email hosting to SMX, a New Zealand email specialist. That change brought the service home and modernised spam filtering and security behind the scenes. The address format didn’t change, and most people simply kept using their familiar @xtra.co.nz identity.
Who can get it? Xtra email is tied to Spark. If you’re a Spark customer, you can generally add or maintain an xtra mailbox. If you leave Spark, options usually exist to keep your address for a fee. The specifics can change over time, so check Spark’s current terms if you’re deciding whether to stay or switch.
How it works
Behind the scenes
Today, xtra email is hosted by SMX on servers in New Zealand and accessed using standard email protocols:
- IMAP (preferred for most people) to sync mail across multiple devices
- POP (legacy option) to download mail to one device
- SMTP to send mail from your device or app
You can sign in through webmail or connect your address to any modern email app on a phone, tablet, or computer. Messages are scanned for spam and viruses server-side, and folders such as Spam/Junk are managed automatically.
Common server settings
These settings are widely used for xtra email accounts:
- Incoming (IMAP): imap.xtra.co.nz, port 993, SSL/TLS on, authentication required
- Incoming (POP): pop3.xtra.co.nz, port 995, SSL/TLS on, authentication required
- Outgoing (SMTP): send.xtra.co.nz, port 465 (SSL/TLS) or 587 (STARTTLS), authentication required
Use your full xtra email address as the username and your xtra password. If you run into issues, confirm the latest settings with Spark support or the Spark help site, as details can be updated.
Types / examples
Ways to access xtra
- Webmail: Handy when you’re on a shared computer or travelling. No setup, just sign in and go.
- IMAP in an app: Best everyday option. Mail stays on the server and syncs across your phone, tablet, and desktop.
- POP in an app: Old-school. Mail is downloaded to one device and can be removed from the server. Useful if you’re often offline and prefer a single archive.
IMAP vs POP for xtra
| Feature | IMAP (imap.xtra.co.nz) | POP (pop3.xtra.co.nz) |
|---|---|---|
| Where mail lives | On the server (syncs to all devices) | On the device that downloads it |
| Best for | People using multiple devices | Single-device users who want a local archive |
| Folder support | Yes, full folder and read/unread sync | Basic inbox download; limited folder handling |
| Offline use | Good with cached mail | Excellent once downloaded |
| Risk if device fails | Low (copies remain on server) | Higher unless you back up the device |
Real-world examples
- A tradie keeps an @xtra.co.nz address on business cards. Using IMAP means quotes sent from the office PC also appear on the phone.
- A retiree on rural broadband uses POP on a laptop so emails are fully available while offline and stored locally.
- A family sets up xtra on iPhones and a shared iPad with IMAP so everyone sees the same read/unread state and folders.
Pros and cons
Why xtra can be a good fit
- Local roots: Hosted in New Zealand and supported by Spark, which many Kiwis already deal with for broadband or mobile.
- Stability: Long-running addresses reduce the hassle of telling every contact you’ve changed email.
- Works everywhere: Any mainstream email app supports xtra via IMAP/POP/SMTP.
- Solid filtering: Server-side spam and virus protection before messages hit your inbox.
Where xtra can fall short
- Lock-in: Your address is tied to an ISP brand. Moving providers may involve a fee to keep it or a migration project to leave it.
- Fewer bells and whistles: It’s a straightforward email service, not a full productivity suite.
- No custom domain: You can’t brand mail as [email protected] with xtra. For that, you’ll want a custom domain and dedicated email hosting.
How to use or choose
Set up xtra email on a phone or computer (IMAP)
- Open your mail app and choose Add Account.
- Select Other/IMAP (not Exchange or POP).
- Enter your name, your full xtra address (for example, [email protected]), and your password.
- Incoming server: imap.xtra.co.nz, port 993, SSL/TLS on. Username is your full xtra address.
- Outgoing server: send.xtra.co.nz, port 465 (SSL/TLS) or 587 (STARTTLS). Turn on “Require authentication” and use the same username and password.
- Save the account, allow the app to sync, then send yourself a test email.
Choosing IMAP or POP
- Pick IMAP if you use more than one device, want the same folders everywhere, and prefer server backups.
- Pick POP if you use one device, want everything stored locally, and often work offline.
Good habits for a tidy xtra inbox
- Create a few clear folders (Invoices, Family, Bookings) and file weekly.
- Use rules/filters in your mail app to auto-file newsletters.
- Empty Spam/Junk and Trash regularly so they don’t hide something you need.
- Back up important mail if you use POP or if your computer holds the only copy.
Staying safe
- Be wary of messages asking you to “confirm your xtra password” or “verify your Spark account.” Phishing is common—go directly to Spark’s site instead of clicking links.
- Use a strong, unique password for your xtra address and change it if you suspect anything odd.
- Keep your phone and computer updated so your mail app uses current security protocols.
Migrating away or running xtra alongside another address
- If you need a new address (for example, a custom domain), you can run both for a while. Update key contacts first, then newsletters and less critical accounts.
- To move old mail, connect both accounts to the same mail app and drag folders across. Give it time; large archives can take hours to copy.
- Consider an auto-reply on xtra for a month or two to share your new address. Turn it off once people have switched.
FAQ
Is xtra email still active?
Yes. Xtra is Spark’s email service using @xtra.co.nz addresses, and it remains in use across New Zealand.
Where do I log in to xtra webmail?
Use Spark’s webmail sign-in page and enter your xtra email address and password. If you can’t find it, visit Spark’s website and search for “webmail.”
What are the xtra email server settings?
Common settings are IMAP: imap.xtra.co.nz (port 993, SSL/TLS), POP: pop3.xtra.co.nz (port 995, SSL/TLS), SMTP: send.xtra.co.nz (port 465 SSL/TLS or 587 STARTTLS). Authentication is required for both incoming and outgoing.
Should I use IMAP or POP with xtra?
IMAP suits most people because it syncs mail across devices. Choose POP only if you prefer a single device holding the archive and understand the backup implications.
Can I keep my xtra email if I leave Spark?
Often, yes—Spark has offered email-only options so you can retain your address even if you move broadband elsewhere. Pricing and availability can change, so check Spark’s current policy before switching.
Does xtra email support standard email apps?
Yes. You can add xtra to Apple Mail, Outlook, Thunderbird, the Gmail app, Samsung Mail, and others using IMAP/POP and SMTP.
How do I reset my xtra password?
Use the password reset option on Spark’s sign-in or webmail page, or contact Spark support if you’re locked out. You may need to confirm account details to prove you’re the owner.
Why am I getting a lot of spam on my xtra address?
Older addresses are widely circulated, which can attract spam. Use the Spam/Junk button to train filters, avoid posting your address publicly, and be careful where you sign up. If spam spikes suddenly, change your password and review forwarding rules to make sure nothing unwanted was added.
My xtra emails aren’t sending from my phone. What should I check?
- Confirm SMTP is set to send.xtra.co.nz with authentication turned on.
- Try port 465 with SSL/TLS or port 587 with STARTTLS.
- Make sure your username is your full xtra address and the password is correct.
- Toggle mobile data/Wi‑Fi off and on, then retry.
Can I use xtra for a small business?
You can, and many do. If branding matters or you plan to grow, consider moving to a custom domain ([email protected]) and dedicated email hosting. You can run both in parallel during a transition.
Will changing from POP to IMAP break anything?
No, but plan it. Back up your POP mail first, add the account again as IMAP, then copy the old local folders to the new IMAP account inside your mail app so they upload to the server.
Final thoughts
Xtra remains a practical, New Zealand-based email option with a lot of history and straightforward tools. If you value a familiar address and local support, it does the job well—especially with IMAP set up correctly. If you need advanced collaboration or a branded domain, you can keep xtra for continuity while you introduce something new. Either way, a few careful settings and good inbox habits will keep your xtra email running smoothly for years to come.
