That's one possibility.

Or maybe it's the list footer. See

One possibility is the host has a limit on how many recipients can be
addressed in one email or sent to within some time frame.

In a hosted situation, it's difficult to deal with bounce info. If
bounce_notify_owner_on_disable is on, the owner will get a copy of any
disabling bounce, but bounces that only increment the score are not
saved or reported. You can set bounce_score_threshold to 1.0 so the
member is disabled and the owner notified on the first bounce, but
then you have the problem of re-enabling everyone which is tedious via
the web. Since you are just setting this up, you could set the
threshold low, send a message, see the bounces and then mass remove
everyone and mass subscribe them back.

Set up a separate test list with only those few addresses. There's no
convenient way to disable delivery for all but a few members and then
re-enable it. As above, you could mass remove all but a few and then
mass subscribe them when you're done.
