GoDaddy to Hostinger Email Migration

I have five active business email addresses hosted on GoDaddy that must be moved to Hostinger without any loss of messages or noticeable downtime. Each mailbox needs its full history—every folder, attachment, and archived item—copied over so users can pick up right where they left off.

Once the data is migrated, I also need the matching accounts created on Hostinger, the MX and any related DNS records updated, and a quick round of testing to be sure sending / receiving works from webmail and the usual clients (Outlook, mobile, etc.). I’ll supply the GoDaddy and Hostinger credentials as soon as we agree to proceed.

Acceptance will be based on:
• All five mailboxes present on Hostinger with complete message history
• Mail flow verified for both inbound and outbound traffic
• No bounce-backs or missing folders after propagation finishes

I believe the DNS records are updated on Godaddy per Hostinger Instructions. You will get temporary delegate access to Godaddy to check DNS records, Hosinger to check what you need there and then you can remote into my computer to set up the 5 email accounts. 4 Are there, adding 1 new one. All emails are currently Outlook 365 emails. Hostinger require IMAP obviously. If you can do this quickly you can earn more by moving my server data from Godaddy to Hostinger. I want this done tonight.
