I’ve used Spark for years and I prefer the interface over the native Gmail app. But Spark’s latency has become a big issue for me. If it’s not fixed soon I will ditch it. ### 1/5 — Nonfunctional *2026-08-26, version 3.19.25* After paying for a subscription for their services, I could not get emails to refresh, sync across devices, or send in a timely manner. I reached out to support with very little help to eventually not receive any responses from their team. I once loved this app but is now unusable. ### 1/5 — Stay Away *2026-08-26, version 3.19.25* After years of loving this app and trying to get other people to use it, I am now running far away as I continue to try and force AI integration and up sales. The app is now an unusable mess and I will be completely deleting and moving on. ### 1/5 — Not operational *2026-08-25, version 3.19.25* Since the last update I have been unable to open emails and can’t seem to delete some emails that won’t send. I delete and they reappear. It isn’t updating my sent file from other devices. It didn’t allow me to opt out of AI. I would send an email to support but it doesn’t work from Spark. This is happening across three devices. ### 5/5 — Good App *2026-08-25, version 3.19.25* I use it to access my hotmail account and found it to be better than Outlook app. ### 5/5 — Back to Workin *2026-08-24, version 3.19.25* Love the app (my no content issue was resolved after a few days) all my emails in ONE location is fantastic. Thank you ### 4/5 — Great *2026-08-23, version 3.19.25* I really like spark it makes email more enjoyable like better spam filters which stops most spam from hitting my inbox. Also like when i add my accounts on one device it syncs across all the rest effortlessly. ### 3/5 — Used for years but slowly getting worse *2026-08-23, version 3.19.25* I’ve used spark and loved it for many years, but the last few versions have made the app worse and sometimes not usable. Repeatedly have outbox mail just failing to send, notifications and sync with my online emails way out. App just generally sluggish compared to how it used to be a few months back. ### 4/5 — Favorite mail handler *2026-08-22, version 3.19.25* Been using Spark for a long time now. My only problem with the current iteration is that I don’t have the ability to opt out of using the AI version. Also, the free version doesn’t seem to be available any more. ### 1/5 — What happened? *2026-08-22, version 3.19.25* App used to be perfect for my simple email workflow and I’ve been using it for years. Now that’s it full of AI features my emails take ages to load. It’s never an issue on my end - I have multiple mail clients I test with. ## Frequently asked questions about Spark Mail ### What does Spark AI Email & Calendar do?
