BlueMail vs Nine (2026): which should you pick?

Pick BlueMail if

• Fits if you want the same email app on your phone, your Mac and a Linux machine
• Works for people with several accounts, since the free plan takes unlimited ones

Look elsewhere if

• Skip it if you want email in a browser tab, as there's no web version
• Not for you if you need S/MIME, SSO or MDM support, which are listed on the Enterprise plan only
• Tight if you were hoping for free AI, because GemAI starts on Plus at $35.99 a year
• Watch out: the website prices Plus at $4.99 a month or $35.99 a year, but the App Store shows $6.99 and $49.99
• Watch out: the Plus trial is 7 days, and the FAQ ties it to yearly subscriptions

Pick Nine if

• Fits if your work mailbox runs on Exchange or Office 365 and you read it on a phone
• Works for people who want to pay once for a mail app

Look elsewhere if

• Skip it if you want calendar and tasks from an IMAP mailbox, as those need ActiveSync
• Skip it if you need a desktop or web app too
• Watch out: the price comes from the Google Play listing, which also shows in-app purchases
• Watch out: Nine Work, the enterprise edition, was Android-only, with iOS described as coming
• Watch out: Play lists a different developer name from the vendor site

BlueMail

• GemAI, email backup on desktop and priority support need the paid Plus plan; S/MIME, SSO and MDM support are listed only on Enterprise.

• The US App Store lists BlueMail+ in-app purchases at $6.99 and $49.99 with no billing period shown; the website prices Plus at $4.99 a month or $35.99 a year.

Nine

• IMAP accounts sync email only; calendar, contacts, tasks and notes need ActiveSync.
• The price comes from the app's Google Play listing, whose wording may be out of date, and the listing also shows in-app purchases.
• Nine Work, the enterprise edition, was Android-only with iOS products described as coming.
• Play lists NextIntelligence.ai as the developer, while the vendor site is branded JiranSoft.
