Why remove https://www.bitrecover.com/email-backup/ ?

Please replace it as it is offering to backup emails from any IMAP based email account to 30+ saving options. Such an easy solution to backup emails from any email application.

No problem to add it but why remove another tool from the list of all tools doing the same as imapsync?

No worries!! You can add this tool as well as mine too for better references!! I hope understands it!!

I now understand you tried and insisted on removing a tool similar to yours in the imapsync README.
