One caveat I could think of: GMail (perhaps other IMAP providers too?)
limits the daily IMAP traffic [*], so if you have more than a few
gigabytes of mail, downloading it in one day could be impossible.

Another GMail-specific caveat is Google insisting on using a
non-discoverable authentication scheme that involves starting a browser
and passing a token back to the client [**], which Claws does not
support, so a workaround is to use an app-specific password and/or
enable access using applications Google calls "less secure" in the
settings [***].
