So they hit send all to their email list, Hang em.
Why would “their email list”, the one they use to solicit campaign contributions, even have the email addresses of foreign politicians?
Stuart Donald, a Scottish member of Parliament (MP) responded to a question on Twitter and confirmed he and many other MP’s have received numerous emails from the Trump campaign soliciting contributions and that they were sent to their @parliament.uk email addresses.
I would also add that I have worked on email campaigns for non-profits using Constant Contact. It is not difficult to filter out something like a .uk email addresses. It could be a "rookie" mistake but even so, a bad one.
The emails came from teamtrump@DonaldJTrump.com. That is evidently a new domain name for the Trump campaign and may be responsible for the high rate of emails going to spam folders – see here:

While previous emails had been sent from @DonaldTrump.com email addresses, the candidate’s fundraising push came from an @DonaldJTrump.com account. It’s that change in domain that likely sent the majority of the emails into spam folders, an easily-avoided mistake.
