It’s too important, too big a feature to fail. When the app sorts on its own or remember the fixed category incoming email belongs. I’ll change grade to 5 stars.

Seit längerem zeigt die App keine Kennzeichen mehr an, dass neue Emails da sind. Das Update dafür kam einfach nicht mehr. Sonst top. App löschen neu Installieren und alle neuesten Updates bringen nichts. Ohne Kennzeichnung nutzlos

I love this app when it works but it kicks me off quite a bit, and signing back in can be frustrating.

There are still painfully few good multi-platform email clients. I’ve used spark on and off for quite a few years. It’s okay for handling both my iCloud and Hotmail accounts, but it’s still very slow to show new emails in the inbox. It’s got more compose features than apple mail, but I’d like to see more options for customising the appearance and layout of the inbox. Also, the Windows app is a long way behind the iOS and Mac apps. I’m paying for a plus subscription but I don’t feel it offers value for money and I’m actively looking for other alternatives.

旧メールアドレスがサーバー切り替わったので更新したら、無料で使ってたテンプレートが有料になってた。以前から使ってた人は無料のままと書いてあるのにどうしても更新されない。。本当ダメなアプリだと思う。 また、普通は迷惑メールにフィルターで区別して、ある程度纏ったら、全て選択」などの機能で、一気にゴミ箱に入れて終わりますが、そういう機能は、有料じゃないと使えません、仕事で使う公開メールなので何百通も迷惑メールが来るのに、手作業で一通一通削除作業します。毎日今では200通以上の偽PayPay勧誘メールなどが届くのです。2,3分毎に1通新しい偽メールが増えていったりします。この面倒くささわかりますか?

I’ve been a Spark Premium subscriber for several years, using it daily for critical business and client communications. Unfortunately, the app has gone sharply downhill, and Readdle’s handling of issues has been extremely disappointing. 1. Paid Features Removed Without Notice Spark quietly removed Read Statuses (read receipts) from my active Premium plan — a feature I relied on for over a year. Support later claimed it was a “bug” that I had access at all, and informed me it now requires the far more expensive Pro plan. Removing an existing paid feature and re-locking it behind a higher tier feels misleading and unethical. 2. Serious, Ongoing Bugs Spark has repeatedly sent scheduled emails even after I deleted them — more than five times — including sensitive reminders to clients. This caused real reputation damage and embarrassed me professionally. On top of that, the app crashes frequently on both iOS and macOS, often while I’m writing important emails, wiping out drafts. Sync delays, random freezes, and unreliable search add to the frustration. 3. Support Has Not Provided Real Solutions Despite months of tickets and follow-ups, support has not resolved any of these issues. I mostly received generic responses, no accountability, and no timeline for fixes. Spark used to be an excellent, trustworthy tool. Today, it’s unstable, unreliable, and feels like it’s being monetized aggressively at the expense of long-time customers. I can no longer recommend it to anyone who needs dependable email for business. Honestly I’m pretty upset and really don’t trust this company to delivery a quality product and to do the right thing when they mess up; let alone fix the endless bugs and issues.

It has been a while that the search is very slow, whether it is in inbox or sent box. Not sure whether the issue started after iOS 26 update. It is very annoying, and needs to be addressed ASAP.
