It’s a common scenario: you’ve created a stunning website for your client and they now want a personalized email address with their custom domain name. This is typically a simple task, but it becomes trickier when the client also wants their old emails migrated to the new mailbox. The good news is that transferring emails to a mailbox with a custom domain name is actually quite easy!

How to Transfer Mail Addresses to a Custom Domain: Domain Setup

Preparing beforehand is crucial to ensure a smooth email migration for your clients. Here is a checklist of what data you’ll need before transferring your clients’ emails to a new mailbox with a custom domain name:

First, get this information:
  1. A list of all the mailboxes that require migration

  2. Access credentials for the existing mailboxes (username, password, mail servers).

  3. Access credentials for the new mailboxes.

  4. Access credentials for the domain admin panel.
Now, setup the new domain:
  1. Log in to the domain admin panel.

  2. Open the DNS / MX settings and add the IP address of the new mail server to the DNS settings. You will most likely also need to set the MX record to point to the new server.

  3. Set the TTL (time-to-live) to the lowest possible value (usually 300). The TTL is the amount of time it takes until the existing DNS records are refreshed.

ℹ️ If you are unsure about how to configure the DNS/MX settings properly, search for “dns mx mail settings [new provider name]” on Google or contact the new provider. They will be happy to send you the correct records.

ℹ️ In case you can’t change the TTL for the DNS settings, its advisable to wait 24h hours before starting the migration. By doing so, you ensure that all the records are updated correctly once you start the migration.

Create the new mailboxes – if they don’t already exist

If the new mailboxes have not been created yet, log in to the control panel of the new web space or server and create the necessary mailboxes. If you don’t have access to the web space, simply ask your client or hosting provider to create the mailboxes for you.
