How to switch email providers without changing your email address
The short answer: use email on a domain you own. If your address is tied to a provider's domain, switching providers usually means changing your address. If your address is on your own domain, you can change the provider behind it while keeping the public address the same.

The difference: rented address vs owned domain
An address like yourname@gmail.com is attached to Google's domain. You can forward it, but you cannot move that exact address to a different provider. An address like you@yourdomain.com belongs to the domain owner. The email host can change while the address people use stays the same.
That is the core reason business email should use a custom domain. The domain becomes the stable identity. Google Workspace, Microsoft 365, Fastmail, Shipmail, or another provider can sit behind it.
Why this avoids provider lock-in
Provider lock-in is not only about features or price. It is also about the cost of telling every customer, vendor, bank, and login service that your email address changed. With a custom domain, the visible address remains stable. Switching providers becomes a technical migration instead of a public identity change.
- Your website, invoices, business cards, and account logins can keep the same address.
- You can change the provider that hosts the mailbox when your needs or pricing change.
- You can create role addresses like hello@, support@, billing@, and founders@ on the same domain.
How switching providers works at a high level
1. Use an address on your own domain
The address should be something like you@yourdomain.com, hello@yourdomain.com, or support@yourdomain.com. If your address ends in gmail.com, outlook.com, or another provider-owned domain, you cannot take that exact address to another host.
2. Recreate the addresses you need at the new host
Before changing DNS, create the same mailboxes, aliases, forwarding rules, and shared addresses with the new provider. That prevents incoming mail from landing at an address the new host does not recognize.
3. Plan what happens to existing mail
A provider switch changes where new mail arrives. It does not automatically copy your old inbox. Export important messages, keep the old account active during the transition, or use the migration tools your old and new providers support.
4. Update MX records when you are ready
MX records live in your domain's DNS settings. They tell the internet which provider receives mail for your domain. When you replace the old provider's MX records with the new provider's MX records, new inbound mail starts routing to the new host after DNS updates propagate.
5. Update sending authentication
Most providers also ask you to update SPF, DKIM, and DMARC records. These records help receiving mail servers understand which systems are allowed to send mail for your domain.
Mailboxes, aliases, and forwarding
A provider migration is a good moment to map what each address actually does. A mailbox is an inbox that can receive and usually send mail. An alias is another address that delivers to an existing mailbox. Forwarding sends mail on to another destination. A shared mailbox is a role inbox multiple people can access.
Do not assume those settings exist at the new provider just because the address existed at the old one. Recreate them deliberately, then test each important address after DNS changes. For a deeper breakdown, read the mailbox vs alias vs forwarding guide.
Switching checklist
- List every mailbox, alias, forwarding address, and shared inbox you use today.
- Create matching addresses at the new provider before changing MX records.
- Decide whether you need old mail copied, exported, or kept in the old account for reference.
- Lower DNS TTL ahead of time if your DNS host lets you and you want faster cutover control.
- Change MX records during a quiet period, then send test messages to the important addresses.
- Keep the old provider active long enough to catch missed settings or delayed DNS propagation.
Where Shipmail fits
Shipmail is built for custom-domain business email without the complexity of running your own mail server or buying a full office suite. Add your domain, copy the DNS records shown in the dashboard, verify the domain, then create the mailboxes your team needs.
If you are setting up domain email for the first time, start with the hello@yourdomain.com guide. If you already know you want to move a domain to Shipmail, follow the custom domain email setup guide.
Frequently asked questions
Can I keep my Gmail address if I leave Gmail?
You can keep using a Gmail account only inside Google's consumer mail service. The portable setup is to use your own domain, such as you@yourdomain.com, with Gmail, Google Workspace, Shipmail, Fastmail, Microsoft 365, or another host behind it.
What are MX records?
MX records are DNS records that say which mail servers receive email for your domain. They are the main switch you change when moving inbound mail from one provider to another.
Do aliases move automatically?
No. Aliases, forwarding rules, and shared mailboxes are provider settings. Recreate the ones you need at the new provider before changing MX records.
Will my old messages move automatically?
No. Changing DNS affects new mail routing. Existing mail stays with the old provider unless you export it, import it, or use a migration tool supported by the providers involved.
