Email migration is genuinely painful and I am sure there's a real market here, so I am not trying to discourage you. But why should I trust a third party with my IMAP credentials?
"Credentials encrypted in memory only and deleted immediately after migration".
I have no way to audit/verify this claim. You're essentially asking users to hand over the keys to their entire email history on faith.
It doesn’t explicitly state anything about the email contents in the privacy policy page. People generally trust their email providers to not snoop in their emails. I wonder why anyone should trust a cloud based service (such as this).
Perhaps not much, but last year I was looking at using IMAP as an export/import path for a relative's old Eudora mails to some much-more-recent client. I insisted on it, after I found out it could no longer make a secure connection to their e-mail server.
That said, I was saved/pleased by Eudora2Unix [0], one of those projects that represents a very long slow burn of successive people with a similar niche struggle. You might think Thunderbird would have an import tool for that, but it's been so many years it didn't survive...
You could use Thunderbird, but it’s slow for large mailboxes and multiple accounts. Being cloud-based, Migrate Wizard moves email faster, tracks progress, retries on errors, and supports incremental syncs - all without running a client locally.

I love imapsync:
https://imapsync.lamiral.info
This is the way projects used to be, and surprisingly excellent ones still are.
The amount of knowledge built into this is incredible:
https://imapsync.lamiral.info/S/news.shtml
// imapsync did 14M to 21M mailboxes transfers per month in 2024, or 0.22% of ALL email traffic

I'm sure the MigrationWiz guys will appreciate your name.
I also can't imagine there is much demand for IMAP only email migration services these days.

What is the advantage of this tool over, you know, just using Thunderbird or another MUA to copy your emails to the new mailbox?
