Which one is for you
Pick Aqua Mail if
- Fits if you read three or four mailboxes from different providers on your phone
- Works for people who would sooner pay once than every month
Look elsewhere if
- Skip it if you want a desktop or web app too, as it's phones only
- Tight if you stay free: one account, with ads and only part of the features
- Pricey if you go monthly, at $9.99 a month
- Watch out: the $1 first-term offer renews at $9.99 a month
- Watch out: the pricing page loads prices with JavaScript, so the yearly view is not on record
Pick Spark Mail if
- Fits if you juggle several email accounts and want them in one inbox on desktop and phone
- Works for anyone who wants snooze and send later without paying
Look elsewhere if
- Skip it if you need email in a browser or on Linux, as there's no version for either
- Not for you if you want AI drafting for free, because Spark +AI needs Plus or higher
- Pricey if you only need a shared support@ inbox, since that sits on Pro at $16.58 a user
- Tight if you lean on the free AI: 5 meeting notes in total and 1 month of history for the Assistant
- Watch out: the 7-day trial applies only when you subscribe in the app, and monthly billing costs 17% more
How we grade them
| 2.2GPAAqua MailFair | 3.0GPASpark MailVery good | |
|---|---|---|
| Value for money | BPremium is $9.99 a month, but the family plan works out at $1.99 a head and the one-off is $99.99. That's under two years of what the typical email app charges, so the one-off is the way in. | CPlus is $8.25 a user a month billed annually ($99), or $10 monthly, which is dead on this category's middle, and it's what unlocks Gatekeeper, Priority, the AI and the integrations. Shared inboxes need Pro at $16.58, double that again. |
| Free plan and trial | CFree covers one account, with ads and only some of the features. Add a second mailbox and you're paying. | AUnlimited email accounts in one Smart Inbox, with snooze, send later, reminders and a calendar, free for good and with no cap on any of it. The AI is the only taster: 5 meeting notes in total and 1 month of history for the Assistant. |
| Features | CUnlimited accounts on paid plans, manual IMAP and POP3, colour-coding and scheduled backups. It does the phone-mail job and the listing shows no real gap, but nothing here goes past the basics. | BA unified Smart Inbox that keeps people apart from newsletters, Gatekeeper to screen new senders, AI that drafts, proofreads, summarises and translates, a calendar with meeting notes, and threads a team can comment on and draft together. The mail job is covered. |
| Ease of use | CNo store rating on record. You still add each mailbox yourself, and there are hundreds of settings to wade through if you go looking. | B4.6 from about 82,600 App Store ratings, just under our 4.7 bar for the top mark. Add your accounts and the Smart Inbox does the sorting itself, with snooze and send later there from the start. |
| Platforms and integrations | CAndroid and iPhone only. No desktop app and no web version, so it's one family of devices. | BMac, Windows, iPhone and Android, taking Google, Outlook, iCloud, Yahoo, Exchange and IMAP accounts, and paid plans plug into Todoist, Asana, Trello, Notion, Slack and Zoom. No web version at all, though, and nothing for Linux. |
| Best for | one inbox for many mailboxes on a phone | one inbox for all your email accounts |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
