Moving Your Email to a New Provider Without Losing a Thing

More people than usual are facing this in 2026, because a wave of internet providers have decided they no longer want to run email. Regional and national ISPs alike have been quietly retiring their mail service, sending out "your inbox is closing" notices and giving customers a deadline to get their messages out. Add the usual reasons — switching to a cheaper internet plan, leaving an address you've outgrown, or a small business moving off an old web host — and "how do I move my email without losing everything?" is one of the more common questions we get.

The good news: in almost every case you do not have to lose a single old message, and you do not have to keep checking two inboxes forever. You just have to do the steps in the right order. Here's how to do it calmly, in plain English.

First, stop tying your email to your internet company

The single most important lesson from the 2026 shutdowns is this: an email address that ends in your internet provider's name (something like yourname@att.net, @spectrum.net, @sbcglobal.net, or a small local ISP) was never really yours to keep. Those addresses usually can't move with you, and what happens when you cancel internet varies a lot by company — some give you a grace period (often around 30 to 90 days), some let you keep the inbox only while the account is paid and in good standing, and some simply delete it. Before you cancel any internet service, check that specific provider's email policy so you know your real deadline.

So the first move is to get an address you actually control and can carry anywhere — a free Gmail, Outlook.com, or iCloud account is fine for most people. If you run a business, the better long-term answer is to register your own domain (yourname@yourbusiness.com) so your email is never again hostage to an internet provider or a web host; you can point it at Google Workspace, Microsoft 365, or any host and move it later without changing your address. Pick the new home first — everything below moves your mail and your life onto it.

The reassuring part: your old mail gets copied, not moved

The reason this feels scary is the fear of clicking something and watching years of email vanish. Here's why that usually won't happen: the standard way to move mail uses a system called IMAP, which copies messages from the old account into the new one while leaving the originals exactly where they are. During the move your email lives in both places at once. Nothing is deleted from the old account unless you go back later and delete it yourself, on purpose, after you've confirmed everything arrived.

That means the safe approach is to copy first and only clean up the old account much later — ideally not at all until you're certain the new one has everything and is working.

The reliable way to copy everything: a desktop email program

The method that works no matter who your old and new providers are is to use a free desktop email program as a "bridge." Mozilla Thunderbird (free, Windows and Mac), Apple Mail (built into every Mac), or Outlook all do this. The idea is simple: add both accounts — the old one and the new one — to the same program, then drag your messages from one to the other.

Step by step: install or open the program and add your old email account to it (you'll need the address and password; most providers set up automatically, and if asked, choose IMAP, not POP, so your folders come across). Add your new account the same way. Wait for both to finish downloading their folders — you'll see the old account's Inbox, Sent, and any folders you made, plus the new (mostly empty) account in the sidebar. Then select the messages in the old Inbox (Ctrl+A on Windows, Command+A on a Mac to grab them all) and drag them onto the new account's Inbox. Repeat for Sent and each folder you care about. The program copies them up to the new server in the background; large mailboxes with thousands of messages can take a while, so leave it running.

Because this only copies, your old account stays intact the whole time. When it's done, log into the new account on its normal website and confirm your messages and folders are really there before you do anything else.

A note on Gmail's built-in import (it's changing in 2026)

Gmail has long had a one-click "Import mail and contacts" tool, and you may have seen it recommended. It still exists for a one-time import on the Gmail website, but Google is phasing this whole area out: the option to continuously "check mail from other accounts" over POP (and the related Gmailify feature) stops accepting new users after the first quarter of 2026 and goes away for existing users in January 2027. In other words, don't build your plan around it. If you want to try the one-time web import to pull an old account in, fine — but the desktop-program method above is the dependable one that isn't being retired and works with any provider.

Google's own recommendation now is to set up forwarding on the old account instead of pulling mail in — which is exactly the next step.

Forward the old address and tell people the new one

Copying your history is only half the job; you also need new messages that are still being sent to the old address to reach you. Set up forwarding inside the old account's settings so anything that arrives there is automatically sent on to your new address. Do this while the old account is still alive — that way you won't miss a thing during the changeover, even from people who haven't updated their address book.

It also helps to turn on an automatic reply (a "vacation responder") on the old account that says "I've moved — please reach me at my new address." One catch worth knowing: some systems, particularly Outlook/Exchange-based ones, won't let you forward and auto-reply at the same time, so if you have to choose, forwarding is the more important of the two. And send a short heads-up to the people who matter most — family, your doctor's office, your accountant — rather than assuming the forward will run forever.

The step almost everyone forgets: update your logins

This is the one that actually bites people, so don't skip it. Your email address is the master key to your online life — it's the "forgot password" and security-code address for your bank, Amazon, utilities, social media, the lot. If the old inbox shuts off and one of those accounts still points to it, you can get locked out of something important with no way to reset it.

Before the old account dies, go through your important logins and change the contact email to the new address: start with banking and anything financial, then your Apple/Google/Microsoft account, shopping, bills, and insurance. A quick way to find them is to search your old inbox for "verify," "welcome," or "receipt" — those emails reveal which services you signed up for over the years. While you're setting up the new account, this is also the right moment to turn on two-factor authentication so the new address is well protected from the start.

Don't cancel the old account too soon

Give yourself an overlap. Keep the old account active for at least a few weeks — a month or two is better — after you've copied everything and set up forwarding. That cushion catches the occasional contact who emails the old address, the annual statement you forgot about, and any login you missed. If your old address is tied to an ISP you're leaving, ask whether they offer an "email-only" option or a grace period, and note the exact date it expires.

Only once you're confident the new account has all your mail, forwarding is working, and your important logins are updated should you let the old one go. There's no rush, and the originals copying over means there's no downside to waiting.

One honest caveat about "keeping" a free address

People sometimes ask if they can take a free address like an @gmail.com or @yahoo.com with them to a different company. You can't — the address itself belongs to that provider and isn't portable. What you can do is exactly what's above: copy the contents into a new account and set the old one to forward. The flip side is the upside of free, provider-independent email: as long as you keep using it, a Gmail or Outlook.com address never disappears just because you changed your internet company, which is the whole reason to get off an ISP address in the first place.

When to let us handle it

If your mailbox is huge, you're juggling several accounts, you're moving a small business onto its own domain, or you simply don't want to risk it, this is a job we do all the time. We'll copy every message across, set up forwarding and the new account properly, make sure your logins are pointed at the new address so nothing locks you out, and confirm it's all there before anything old is closed.
