They are a giant in this industry and deliver emails pretty good, but sometimes emails wind up in the spam folder for no good reason at all. Guess it's probably only so much they can control there. But although they're a the top of this field, there are more affordable email management options that can do an equal or better job. So my advice is not to get caught up by big names and do some research on other companies too in order t find the best most affordable solution for you.
