1. 4/5Missing one thing.

   I love everything about this app. It will replace my regular email one day, but for now I use it WITH my email. The reason is because there is no option to be able to delete in bigger quantities. Currently you can delete a message and it will give you an option to delete that senders previous emails en masse, but there is no option to choose many different senders to delete at once. There should be an option to choose several emails you would like to delete, and much like the current method, it can ask you to delete the selected messages, or the bulk quantity of all the previous senders messages. It would be much easier to remove one sender from the bulk quantity I am deleting at the time if for some reason I didn't want to delete all those emails from that sender, go back and delete all the ones I chose, then just choose that one email again and delete that one, than to have to do it all one sender at a time I have 42,000 emails that need to be deleted and obviously it is too hard to do it one by one. Being able to delete many emails from one sender is a huge upside to this app but being able to choose many different centers and then deleting all their previous emails would really help clear up my inbox

2. 5/5Finally perfect

   I was searching for something after Outlook quit playing nice with my main email (Verizon, which is technically AOL Mail now) and repeatedly signing out of it and requiring me to log in at any given time. The final straw came when I checked my email on a Monday and I hadn't received an email since Friday. I found this app in a top ten list online, and now I wonder where it's been my whole iPhone life. I love the text conversation layout that makes it very easy to keep track of who you're replying to, especially in a group email where replies can be many. The "other" inbox, like Outlook, keeps the clutter separate and lets you focus on the important emails first. When I first downloaded and reviewed the app, the setting for calendars would not work for me no matter how many times I tapped that option in Settings, so I couldn't change them. I also wished there was a way to customize the swipe action like you can in Outlook. "Archive" is not important enough for me to swipe ALL the way left before I see the Trash option. However, both issues were resolved pretty quickly after the support team took a look. Therefore, I can't really find fault with this app. It's well worth trying out if you're looking for a solid third-party email solution on iOS. (There was a later issue with my account being wrongly flagged for having a custom domain and being pestered to subscribe to Spike Pro, but that was quickly resolved. Great customer service!)

3. 5/5Great app—takes a while to learn the icons and ways to do things

   I have used many email apps. So far, this one is the most usable, at least for my personal use. (I use corporate Outlook on an exchange server at work.) I love the way that Spike is organized by People and looks like and is organized like text message chat. I also love (and find essential) that the people at the top of the list are the ones with the most recent emails. (It is hard to say emails, because they look like texts.) Yet when you send a “text”, the recipient sees what looks like a formatted email in the traditional appearance. I find myself reading, responding, moving, archiving, and trashing emails at lightning speed compared to other email apps! I have about 100,000 emails, and my backlog is disappearing fast!!! In the meantime, all my contacts must be amazed at how responsive I have become!!! Another great feature: my start-up questions were answered in a friendly and efficient manner within hours by real humans, not by automated responses or canned instructions.

4. 5/5Fast, Fun, Functional

   This is an updated review. I was experiencing difficulty with my iCloud account syncing, but that has been resolved. I’m giving 5 stars because this app does what I need it to do - and it’s fast, fun, and functional. Email works at lightening speed where other apps (even native apps) are sluggish and cumbersome. It’s fun to use! The layout is minimal and it’s easy to work quickly through the inbox. Finally, the thing works. I need something reliable for multiple accounts that will help me stay up to speed for personal and professional email. This is the best I’ve seen. One request - please allow me to choose whether or not to include a signature while typing an email. I’d love to have the choice to include it or not include it based on the kinds of emails I’m sending WHILE they are being composed. It’s too much of a pain to go into settings each time. This is a particular gripe when working in my professional inboxes. Sometimes I need that signature. Other times, I don’t need that full signature. Thank you for making something awesome!

5. 5/5A pleasant surprise

   I work for a school and I get at least 40+ emails a day from different departments and students. And most of them are long email threads which at times were difficult to find a particular email within that thread and also difficult to find attachments when the thread was over 20+ emails long. I strictly use my iPad pro for everything and I’ve tried pretty much all the decent email apps that I could find from the app store. Most of them hav only lasted less than 2 minutes on my ipad because they weren’t up to par. I currently have 5 different email apps(Apple Mail, Outlook, Spark, Edison and Gmail) on my ipad because none of them can do everything I want an email app to do. So I use different ones for specific tasks. I always search on the web for reviews on email apps because I wanted to find THE email app that I could use. One day Spike came up on one of those review site. So I installed the app thinking this was going to be just like one of those many apps that I’ve tried and deleted after 2 minutes. To my pleasant surprise, the text messaging style format was very easy to get use to and it really worked well on long email threads. I didn’t have to click individual emails to see them, I could just scroll up and down to see ALL of the email conversations within that email thread. And the attachments also showed up and very easy to find. It’s been a week since 9/13, Spike is not only still on my ipad but it also has became my main go to mail app now. Spike has checked many boxes on my list. I DO wish that they could bring one of the features from it’s desktop counterpart to the iOS version which is the “Send later” feature. So please bring it to the iOS version on the next update! Well, this review is getting awfully long and I’m not the kind of person who writes reviews all the time. So here you have it. Give it a try and see if this app is for you or not.
