How to Switch Web Hosting Without Losing Your Email

You can absolutely switch web hosts without losing a single email, as long as you handle the DNS deliberately. Almost every horror story about email vanishing during a host move comes down to one thing: the mail-routing records got dropped when the website moved. The fix is to know what those records are before you start, and to move your website and your email as two separate jobs. Here's the safe way through it.

The reason this feels scary is that hosting and email often ride on the same account, so it looks like moving one must break the other. It doesn't have to. Once you see the pieces, the whole thing is methodical rather than nerve-wracking.

Why email breaks during a host move

Your domain's DNS is a small set of records that tells the internet where to send different kinds of traffic. Two of those records matter most here:

When you move hosts, the new host often sets up fresh DNS with only the website record filled in. If your old email lived on the old host, its MX record doesn't come along, and mail stops arriving. That's the whole failure, and it's completely avoidable.

What you'll need

• Login access to where your DNS is currently managed (your registrar, old host, or a service like Cloudflare).
• Your new hosting account, ready to go.
• A clear note of where your email actually lives now (your old host, or a service like Google Workspace or Microsoft 365).
• About an hour, plus a quiet day when a brief hiccup wouldn't hurt.

How to switch hosts and keep your email

1. 1Record every existing DNS record first. This is the step that saves you. Log into wherever your DNS lives and write down, or screenshot, all of it: every A, CNAME, MX, and TXT record, exactly as written. This is your safety copy. If anything goes wrong, you can put it all back.
2. 2Confirm where your email is hosted. Look at your MX records. If they point to your old web host, your email is on that host and you'll need to plan for it. If they point to Google or Microsoft, your email is separate and moving your website won't touch it at all. That's the easy case.
3. 3Lower your DNS TTL a day ahead. TTL is how long the internet caches your records. Drop it to 300 seconds (five minutes) the day before you switch. This makes your later changes take effect in minutes instead of hours, so any hiccup is short.
4. 4Set up the website on the new host before switching anything. Upload your files, restore your database, and confirm the site works on the new host using a temporary preview or the host's staging URL. Nothing is live yet, so there's no risk here.
5. 5Move email as its own separate step, if it needs moving. If your email was on the old host, get the new mailboxes ready first, or better, move email onto a dedicated service like Google Workspace or Microsoft 365 so it never rides on your web host again. Copy over existing messages before you cut anything.
6. 6Update the DNS to point at the new host, and re-enter your MX and TXT records. Change the website (A) record to the new host. Then carefully re-enter your MX and email TXT records from the copy you made in step one. Do not rely on the new host to fill these in for you.
7. 7Test before you celebrate. Load your website. Send yourself an email from an outside account and confirm it arrives. Send one out and confirm it doesn't land in spam. Only when all three work is the move truly done.

The safest setup going forward

The single best thing you can do to make future moves painless is to stop letting your email live on your web host. When your email runs on a dedicated service like Google Workspace or Microsoft 365, changing hosts becomes a website-only job, and your mail never even notices. It's worth doing once so you never have to think about this again.

When you'd rather hand the whole move to us

Host migrations are routine for us and nerve-wracking for most owners, which is exactly the kind of task worth handing off. We map your current DNS, move the site, keep email intact, and stay on the old host until we've confirmed nothing broke. It's included in our maintenance plans, which start at $99 a month, or we can handle a one-time migration.

We're near Seattle and have moved sites for businesses across the Puget Sound and around the country since 2011. If the email part is what's making you hesitate, that's the part we're most careful about. Give us a call at (425) 314-1415 and we'll talk it through.
