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,

With Spike, you can easily delete messages in bulk from multiple senders and even thousands or messages at a time, in just 1 tap. 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.

No “In-App Purchases” Is Misleading

I work at a very small business and only recently was given an email address there. I don’t even use it every day. After looking at a few options, I decided to try Spike—partly because there were no “in-app purchases” listed. I had barely used it enough to really get a feel for it yet when I started getting notices about my “Free Trial” coming to an end. What?
Considering some of the paid email apps that I passed on because they required a subscription, I figured maybe it would be only a couple of bucks per month. I click subscribe. I’m taken to a page that tells me it’ll be $12/month to keep using it for my “Business email” that I use like once or twice each week. I won’t even pay $12/month for a video streaming service that I’d use every day. That is a ridiculous price and a suspect way to implement it. I was under the impression that Apple did not allow apps with subscriptions that didn’t use in-app purchases. (Didn’t a large video game company recently get taken down for doing just that?)
So, I guess I’m deleting Spike and will never discover if it's even worth $12/month.
I’ll give it a few stars because it seemed like a decent app, but I have no idea how much value comes with the cost.
