Email migration with message sync and delivery tests
For many companies email matters more than the website — it carries customer contact, invoices, orders and business agreements. We migrate mailboxes, messages and configuration with a planned MX switch plus sending and receiving tests.
What an email migration involves
Email migration is more than creating new accounts on a new server. It means transferring the entire correspondence history over IMAP, configuring DNS records and verifying that mail doesn't land in spam after the change of provider.
Incorrect SPF, DKIM or DMARC configuration can cause sent messages to land in recipients' spam folders — directly affecting the company's reputation.
What an email migration includes
What we check before an email migration
Number and size of mailboxes
We inventory the mailboxes, their size and the number of messages to move over IMAP.
Current and new provider
We verify IMAP migration options between the current and target mail servers.
DNS access
We check who manages the domain's DNS and which MX records need changing.
Aliases and forwarding
We identify all aliases and forwarders that must work on the new server.
User devices
We determine which devices and email clients the mailboxes must work on after the migration.
SPF, DKIM, DMARC
We verify the current authentication records and plan their configuration at the new provider.
What can go wrong with an unplanned email migration?
How an email migration works
Mailbox analysis
We inventory accounts, aliases, mailbox sizes and user devices.
Preparing the new accounts
We create mailboxes and aliases on the new mail server.
Message sync over IMAP
We move the correspondence history to the new server — in the background, without interrupting your mail.
Changing DNS records
We change the MX, SPF, DKIM and DMARC records — mail starts flowing through the new server.
Send and receive tests
We verify sending, receiving and the correctness of the authentication records.
Device configuration
We help configure email clients (Outlook, Thunderbird, Apple Mail) and mobile devices.
Email migration — common questions
Tell us the number of mailboxes — we'll prepare an email migration plan.
Use the configurator or describe your situation directly. You don't need to know which DNS records to change — we'll do it for you.
