The ability to send multiple attachments at once, having them in one place is very helpful! I wish there was an option for customizing how many emails are sent out per day or week instead of it being always 24 hours/day. There's nothing i dislike about this product yet because they haven't released any updates but if their new version comes out someday then we will know what improvements can be made. We use flep as our main mail provider so all incoming messages go through here first before moving onto Gmail. This has helped me organize my inboxes much better than using other methods like gmail labels etc., It also allows us to keep track of important documents from different sources such as clients' companies via google drive without cluttering up your personal account. Fleps customer service isn't great either since most people who call aren't knowledgeable enough to answer questions pertaining to business purposes which makes communication difficult sometimes. Try giving it.
