Features
Everything MailLoyal does
A full mail client for iPhone, iPad, Mac and Android, built around your own mail server. Every feature on this page is free on every platform.
Setup
Accounts and setup
Sign in with an address and a password. MailLoyal works out the rest, and when it can’t, it says exactly why.
Email-first sign-in
Known providers are recognised as you type. An unknown domain gets one lookup for its published settings: Mozilla’s directory first, then your domain’s own autoconfig.
Built for cPanel
Tries mail., imap. and your domain itself on the secure ports, and signs in with the full address or the part before the @, whichever your server wants.
App passwords, guided
Step-by-step help for Gmail, iCloud, Yahoo and Fastmail, a button to the right page, and a check that the password is the right length.
Encrypted or nothing
SSL/TLS and STARTTLS are tried side by side. There is no unencrypted option anywhere in the app, and port 25 is never used.
Certificate decisions
A mismatched, expired or self-signed certificate is shown with its details and fingerprint. Trust covers that exact fingerprint, on that server only.
Connection checks
Eight named steps, from finding your server to listing folders, a fix for each kind of failure, and diagnostics you can copy with passwords removed.
Login templates
Save a host pattern, ports and security as a template to prefill new accounts, handy if you look after several mailboxes on one host.
Remove from this device
Removing an account deletes its cached mail and saved password from the device. Your mail stays on the server.
Reading
Reading and organising
Fast, calm and safe to open.
All inboxes
Read every account in one list, or one account at a time.
Conversations
Replies are grouped into threads on your device, with a count on the row.
Search
Instant search over subjects, senders and the mail on your device, with Unread, Flagged and Has attachment filters, and a search of every folder on the server when nothing matches.
Swipe, select, undo
Swipe to archive or delete, long-press to select several, and undo what you didn’t mean.
Offline, then in sync
Mail you’ve opened is there without a connection. Flags, moves and deletions apply at once and are replayed on the server when you reconnect.
Safe HTML
Messages are rebuilt from an allowlist: no scripts, no frames, no forms, and no JavaScript anywhere.
Deceptive links
A link whose text shows one address but opens another asks before it goes anywhere.
Remote images, your call
Hidden in Spam until you allow them; hidden everywhere once you turn on Ask before loading images. Allow per message or per sender.
Block a sender
Future mail from them goes straight to Spam, by a rule kept on your device.
Dark mode for mail
Messages are recoloured for dark mode, with an Original colours switch.
Writing
Writing
Three views of one message, and a toolbox that stays out of the way.
Plain, formatted or HTML
Start in plain text, switch to formatting when you want it, or edit the HTML source. MailLoyal warns before a switch would lose anything, and a plain-text version always goes along.
A full toolbox
Headings, fonts and sizes, bold to subscript, text and highlight colours with a custom picker, alignment, lists, quotes, code, links, indents and a divider.
Insert and tools
Files, photos, the camera, emoji and today’s date; find and replace, a word count, and paste as plain text.
Recipients
Suggestions come from the addresses in your own mail. Your device’s address book is never read.
Undo send
Five seconds to take a message back, and an Outbox that keeps what couldn’t be sent and retries it safely.
Drafts that survive
Drafts are saved on the device as you write, even if the app is closed.
Attachment limits
A meter shows how much you’ve attached against your server’s own limit, before you press Send.
Compose from anywhere
On Android, mailto: links and sharing open a new message. On iPhone and iPad, the Compose Email shortcut works with Siri and Shortcuts (iOS 16 or later).
Signatures
Signatures
Designed signatures that survive the trip, with or without AI.
As many as you like
Each with HTML and plain-text versions. Choose defaults for new messages, replies and forwards, and pick any signature while writing.
Six built-in layouts
Logo card, Classic, Stacked, Inline, Accent bar and Minimal, in a professional, friendly or minimal tone. They work offline and need no key.
AI designs
With your own key, three designs per request, and Update with AI to change one in your own words.
Send by email
Send up to 20 signatures to yourself or someone else in a designed email. The other side reviews them before anything is added.
Safe to receive
Only the small attached file is read, hidden text is made visible, the logo stays hidden until you allow it, and a received signature never becomes a default by itself.
Move between devices
Share a file with AirDrop or Nearby Share, save it, or copy it to the clipboard, then import it on the other device.
AI assistant
AI assistant, optional
Off until you turn it on, on your own key, and it never sends anything for you.
Your key, your provider
Anthropic (Claude) or OpenAI. Your key is stored in the device’s keychain and requests go straight to the provider; MailLoyal has no AI service of its own.
Draft a reply
Write a few notes in any language and choose a tone (Professional, Formal, Warm, Direct) and a length. The draft can use up to six earlier messages of that conversation, which you can switch off per draft.
Write with AI
Turn notes into a new email. It sends your notes, the subject and recipients’ display names, and no mail from your mailbox.
Six writing tools
Improve writing, Make it shorter, Fix spelling and grammar, Change tone, Translate, and Update with your own instruction. One Undo restores your text.
Four separate consents
Signatures, reply drafting, writing new emails and the writing tools each have their own switch. Changing provider asks again.
You press Send
Drafts land in the editor. Gaps the AI couldn’t fill are highlighted in [brackets], and Send asks before they go out.
What is never sent
Your mail password, your contacts, your folder list and other conversations. People appear by display name, never by email address.
The privacy policy lists exactly what each AI feature sends: section 3.3.
Notifications
Notifications
Made on your device, from mail it fetched. There is no push server, and no third party learns when your mail arrives.
Android: within seconds
MailLoyal keeps a connection to your server open, so new mail arrives within seconds. Android allows this for six hours a day; then MailLoyal checks every 15 minutes until you next open it.
iPhone and iPad: Fetch
iOS decides when apps may check for mail, typically every 15–60 minutes, and never in Low Power Mode. For instant mail on iOS, keep MailLoyal open.
Mac
MailLoyal checks for mail while it is open; notifications stop when you quit it.
Per account
All new mail, VIPs only or nothing, with sound and vibration choices, quiet hours and an unread badge.
Actions
Mark read or Archive straight from the notification.
Privacy
Privacy and security
We cannot read your mail. We have no infrastructure that could.
No account, no server
Nothing to sign up for. Your accounts exist only on the device you set them up on.
The keychain, only
Mail passwords and API keys live in the iOS or macOS Keychain or the Android Keystore, never in the database, preferences or a log.
Redacted diagnostics
Passwords and sign-in payloads are removed before a diagnostic line is even created, so a copied report cannot leak them.
No MailLoyal analytics
No analytics or crash-reporting service of our own is built in. On iPhone, iPad and Android, Google’s ad software sends Google the data set out in the privacy policy.
Contacts stay yours
Your address book is never read, and a photo reaches MailLoyal only when you pick it.
No certificate shortcuts
There is no “ignore certificate errors” switch. A certificate that can’t be verified is shown to you, every time.
Read the full privacy policy.
Appearance
Appearance, layout and languages
Your colours, your language, your screen.
Eight accents and 24 hues
Viridian, Teal, Harbour, Indigo, Plum, Rose, Ember and Moss, or any of 24 custom hues, all tuned for readable contrast.
Four themes
Follow your device, or choose Light, Dark or Black, a true black for OLED screens.
Text size and density
Text from 85% to 130%, and a comfortable or compact message list, with a live preview.
47 languages
Following your device or chosen in Settings. Arabic, Hebrew and Urdu lay out right to left, and each email keeps its own direction.
iPad and Mac layouts
On a wide screen, the message list sits beside the open message, with ⌘N to write, ⌘F to search and Esc to go back.
Bundled typefaces
Plus Jakarta Sans and Inter ship inside the app, so it fetches no fonts from anywhere.
