You don't need to iterate the array. Just:
>>> x = ['[email protected]', '[email protected]']
>>> x
['[email protected]', '[email protected]']
>>> x.remove('[email protected]')
>>> x
['[email protected]']
This will remove the first occurence that matches the string.
EDIT: After your edit, you still don't need to iterate over. Just do:
index = initial_list.index(item1)
del initial_list[index]
del other_list[index]

Using filter() and lambda would provide a neat and terse method of removing unwanted values:
newEmails = list(filter(lambda x : x != '[email protected]', emails))
This does not modify emails. It creates the new list newEmails containing only elements for which the anonymous function returned True.

To remove the first occurrence of an element, use list.remove:
>>> xs = ['a', 'b', 'c', 'd']
>>> xs.remove('b')
>>> print(xs)
['a', 'c', 'd']
To remove all occurrences of an element, use a list comprehension:
>>> xs = ['a', 'b', 'c', 'd', 'b', 'b', 'b', 'b']
>>> xs = [x for x in xs if x != 'b']
>>> print(xs)
['a', 'c', 'd']

Usually Python will throw an Exception if you tell it to do something it can't so you'll have to do either:
if c in a:
a.remove(c)
or:
try:
a.remove(c)
except ValueError:
pass
An Exception isn't necessarily a bad thing as long as it's one you're expecting and handle properly.

Use del and specify the index of the element you want to delete:
>>> a = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> del a[-1]
>>> a
[0, 1, 2, 3, 4, 5, 6, 7, 8]
Also supports slices:
>>> del a[2:4]
>>> a
[0, 1, 4, 5, 6, 7, 8, 9]

You probably want pop:
a = ['a', 'b', 'c', 'd']
a.pop(1)
# now a is ['a', 'c', 'd']
By default, pop without any arguments removes the last item:
a = ['a', 'b', 'c', 'd']
a.pop()
# now a is ['a', 'b', 'c']
