How to Move From Gmail to Business Email Without Losing Mail

Switching from a free Gmail address to email on your own domain feels risky: what about old conversations, saved contacts and customers who only know your Gmail? With a little planning, the move is smooth and nothing is lost. Here’s the plan we recommend.

Step 1: Set up your new business email first

Don’t change anything in Gmail yet. Create your mailbox on your own domain and add the DNS records — our setup guide covers this. Send yourself a test email in both directions before you tell anyone.

Step 2: Add both accounts to one mail app

The easiest way to work during the switch is to see both mailboxes in one place:

• Phone: add the business mailbox to the Gmail app via IMAP — see phone and Outlook setup.
• Computer: add both accounts to Outlook or Thunderbird.

Step 3: Copy the old emails you need

You have three options, from simplest to most complete:

1. Leave them in Gmail. Gmail stays free as an archive. Search it when you need something old.
2. Copy important folders. In Outlook or Thunderbird with both accounts added, select messages or folders in Gmail and drag them into your new mailbox. They are copied over IMAP.
3. Copy everything. Do the same for all folders. Check your plan’s storage first — years of attachments can take several gigabytes.

Copy in batches of a few hundred messages at a time. Large drags can time out halfway.

Step 4: Move your contacts

In Google Contacts choose Export → vCard. Import the file into your phone’s contacts or your desktop mail app. Your contacts are not tied to an email address, so this is quick.

Step 5: Forward new Gmail messages for a while

In Gmail open Settings → Forwarding and POP/IMAP → Add a forwarding address and enter your new business address. Gmail sends a confirmation email to the new mailbox. From then on, anything sent to the old address also arrives in your new inbox, so no customer is missed during the transition.

Step 6: Tell people about your new address

• Update your email signature, website, Google Business Profile, invoices and visiting cards.
• Send a short, friendly note to regular customers and suppliers.
• When someone writes to the old address, reply from the new one — they’ll pick it up naturally.

Step 7: Update logins and services

Many accounts — banks, GST portal, payment gateways, marketplaces — send alerts to your Gmail. Change the contact email in each one over the next few weeks. Make a list as alerts come in to the old address.

Step 8: Keep Gmail as a backup, not your main inbox

After two or three months, almost all mail will arrive at the new address directly. Keep forwarding on and the Gmail account alive — it costs nothing and catches the occasional old contact.

That’s it: a professional address, your old mail safe, and no lost customers. If you are still deciding, read free Gmail vs business email, or compare our plans.
