You ruined it.

Please bring back the old one. This update is really terrible.

Can’t read messages if you can’t scroll

I’ve been a Spark user for many years but it is becoming unusable on iPhone. I regularly experience an email I open “acting stuck” - it won’t let me scroll beyond the opening image. So frustrating. Also, please take AI out of everything forever unless someone specifically asks for it. Ridiculous to force these “features” no one asked for in all your users.

Infuriating automation. Not a serious app.

It makes videos much bigger when it prepares them to be attached to an email, then tells you they're too big to send and to upgrade to use Spark Cloud.

First, don't change my videos.
Second, both my provider and the recipient's allow attachments up to 50MB, and that's pretty standard, so why is this app putting a lower limit on?

iOS Mail has mandatory compression (again, why?) but at least I can send something, even if it's degraded. This is just a blocker to getting anything done. Joke of an email app.

Updated Microsoft account connection breaks Spark Classic

Without warning, or an option to decline, Spark updates your MS account with a new connection protocol which breaks MS account support in Spark Classic. Readdle has no intention of updating Spark Classic to support this new protocol (I asked…), and there is no way to have the IOS/iPadOS version of Spark not use this new protocol. So the options are to stop using Spark on my iPhone and iPad, or stop using it on my Mac (the “new” Spark Desktop version is still terrible, so that’s a non-starter).

I love Spark, so I’m pretty upset by this situation and by Readdle’s response that Classic won’t get updated.

I don’t want to look for a new email program, but this update is forcing me to do so.

Broke app emails marked as spam don’t goto spam

I have marked as spam hundreds of emails and it doesn’t matter because it isn’t sending new email from exact same sender to spam!!

Can not block a sender who keeps spamming me and can’t report spam without paying
Searching for a new app.
In 2026 unable to block or report spam is idiotic and unusable
