Make tackling an unruly email inbox a whole lot more pleasant. Thanks to a painless setup process and a sharp layout, the true value comes from its clever interface and flexible customisation, bubbling important emails to the top, while filtering out the noise.

If you ever want to send emails to groups you should not download the so called upgrade to this version. Interaction with other apps has been lost as has the ability to sent an email to a contact group. Sadly the developers seem to be obsessed by AI at the expense of the efficiency of the basic email app. I regret paying an annual subscription for an app that no longer does what it did before the so called upgrade. This is a pity, because the customer service reps are friendly and informative, but seemingly unable to influence the developers. If the issue were to be addressed I would have give the app a four star rating.Readdle's reply to this review was that they had prioritized AI to support email efficiency. They do not explain why, in doing so they felt it necessary to remove other aspects of email efficiency that existed in the free version. Furthermore in my correspondence there have been assurances that these features will be restored, but they are unable to say when, even though I have asked if it is likely to be before my next annual payment is due.

Hello Hermione! Thank you for your feedback. We have prioritized the release of the Spark + AI feature due to its significant impact on email writing efficiency. While we recognize the importance of other features such as Integrations and the ability to send an email to a contact group, we are actively working to deliver them to our users. Rest assured, we are dedicated to providing the features that our users know and love, and they remain a top priority for us. Hope you`ll enjoy Spark again once we accomplish feature parity. Elmira

Great initially. But just too slow!

When I started using Spark I thought it was great. Refreshing and enjoyable user experience. Unfortunately I have now binned this app off as for me, as a heavy email user, the app has just become borderline unusable. Emails are slow to arrive, and ridiculously slow to load. I simply don't have the time or patience to wait 10 mins to read an email. The desktop app also has this really annoying thing where it wants to sync the database right as you need to quite the app, sometimes hindering restart or shut down times. It is also slow to receive and load emails too. So I have also binned the desktop app off as well. I reached out to the Readle team via email to ask them to fix the issues, as I really do like the interface and ideally I would have liked to continue using the app. But I had no response which indicates to me that they are not over bothered in fixing the problems. Updates comes through but they seem more interested in adding new features rather than fixing core issues to make the app actually work in a robust manner. It's just become extremely unproductive to use. I have moved back to Outlook as it exhibits none of the issues above and work flawlessly. Mail also works absolutely fine but I prefer Outlook. At this current point in time I could not recommend this app sadly.

The last update is a mess. Is it a ploy to upgrade to Premium?

It randomly groups emails together that are unrelated. It duplicates these emails. Once they are grouped they can’t be ungrouped. So if you delete or move one email it deletes/moves all the emails. E.g. I was having a conversation with Sue. Spark itself added emails from Argos and Parcelforce to the conversation. Also an important email I set aside has now disappeared and I can’t retrieve it in Spark. It’s a mess. When you have unread emails in different folders (e.g. People, Notifications, Newsletters) you used to be able to tap Mark Read on each folder individually, now it marks them as read in all folders simultaneously and I have to sort through them all in the Seen folder. Apparently “Done” is the new name for Archive, but the emails still go into the Archived folder so there’s a mismatch there. I also don’t like the “Sent with Spark” tag which you have to pay £42/year to remove. I don’t want recipients to know what email app I’m using as I believe this has security implications if it gets into the hands of a hacker. Spark has worked fine for years until this last update. I’m disappointed. The developer should get the Free version right before releasing a Premium version. They are trying to run before they can walk. My advice to anyone thinking of upgrading to Premium is please don’t.
