Don't Lose Your Email: Moving Your Business Inbox to a New Domain

When you move your business to a better domain name, most people think about the website. That's the visible part. But your email address lives on the same domain. If your website is at joesplumbing123.net, your email is probably joe@joesplumbing123.net. Change the domain and that address stops working unless you plan for it.

Losing email is worse than losing a website for a few days. A quote request goes nowhere. A customer replies to an old thread and gets a bounce. You miss the message and never know it came. The good news: with a little order of operations, you can keep email when changing domain name and not drop a single message.

First, understand what actually changes

Your email has two parts you care about here:

• The address itself — the part after the @. That's your domain. New domain means a new address.
• The mailbox — where your messages, contacts, and folders live. That's your email provider (Google Workspace, Microsoft 365, or whatever your host gave you).

These are separate. You can keep the same provider and just point it at the new domain. Or you can switch providers at the same time. Doing both at once is more work, so if you can, change one thing at a time.

The safe order to do it

Here's the sequence that keeps mail flowing the whole way through.

1. Don't cancel anything on the old domain yet

Your old domain needs to stay active. Not just the website — the email routing behind it. As long as you own the old domain and keep its email settings in place, messages to your old address still arrive. Keep it running for at least a year. A slow customer might email the old address six months from now.

2. Set up email on the new domain

Add the new domain to your email provider and create matching mailboxes. If you were joe@oldname.net, make joe@newname.com. This means adding a few DNS records so mail knows where to go — usually an MX record, plus SPF and DKIM records that keep your mail out of spam folders. Your provider gives you the exact records to paste in. Here's Google's guide to MX records if you're on Workspace, and Microsoft's guide if you're on 365.

3. Send yourself a test message

Before you tell anyone the new address, email it from your phone. Make sure it lands. Then reply and make sure that goes through too. Do this from an outside account, not just from inside the same system.

4. Forward the old address to the new one

This is the piece most people skip, and it's the one that saves you. Set your old address to forward every incoming message to your new address. Now a customer who emails joe@oldname.net still reaches you at joe@newname.com. You read it, you reply, and life goes on. Forwarding is usually a one-line setting in your email provider.

5. Update where your address is written down

Your email is printed and typed in more places than you'd guess:

• Your website's contact page and footer
• Your email signature
• Invoices, quotes, and estimate templates
• Business cards, trucks, and signage (as you reprint)
• Your Google Business Profile and other listings

You don't have to fix all of it in a day. The forwarding buys you time. But work through the list so new customers get the new address from the start. Updating your listings goes hand in hand with the website move — see updating your Google Business Profile and listings after a domain move.

A few things that trip people up

Don't let the old domain expire. If it lapses, forwarding stops and old-address mail bounces. Set it to auto-renew and put a note in your calendar.

Watch your spam folder for a week. New domains sometimes get filtered until providers trust them. If replies aren't landing, check that your SPF and DKIM records are set right. ICANN and your provider both have plain explanations of how mail routing works if you want to dig in.

Log in to any account tied to your old email. Banks, software, your domain registrar, your accountant's portal — update the contact email on those too, so password resets and receipts follow you.

Where this fits in the bigger move

Email is one leg of the whole switch. The website move has its own steps that matter just as much for getting found. Before you flip anything, walk through the pre-move checklist. After the site is live, set up 301 redirects from your old domain to your new one and then tell Google you moved so your rankings follow. Do those and email in the right order, and the whole thing goes smoothly.
