Missing 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

Hi there,

You can easily delete messages in bulk from multiple senders and even thousands at a time. To select multiple messages, tap on the small ‘Check’ icon (top right) above your messages. This will select all the messages. You can choose if to bulk delete/ archive/ mark as read.

Let us know if this helped you out. We'd love to know how many messages are in your inbox now :) We're happy to explain further - send us a message to and we'll be happy to help you out.

A great people focused email app

Love the priority vs other granularity for notifications. I have been opposed to using email as chat; preferring tools like slack/messages to fill those gaps. This is the first tool to make me reconsider - it makes email feel like texting by removing the extraneous bits and making quick replies.

I have many apps for communications based on the person of the context - and now for people who use email to quickly communicate I have an app for that too. This isn’t a replacement for my email app anymore than slack is a replacement for texting. Normally I turn off all email notifications and process my inbox on an alter schedule - but by using Spike I can now quickly reply to those people who see email more as chat.. in the same way I use wechat, line, Facebook messenger, etc. for those who prefer chat on this platforms. Given the chat like features such as read stays, grouping attachment in the same bubble - is really is just one more chat app for the people who prefer email.

Finally 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!)
