Custom email addressSend and receive emails using your own website domain (e.g. name@yourdomain.co.uk).
Multiple inboxesSet up and manage as many separate mailboxes as you need, across all of your domains.
Multiple addresses & catch-allManage extra addresses like hello@ or support@ from a single inbox. Replies automatically go from the address the email was sent to, with catch-all support for each domain.
Email forwardingAutomatically pass incoming emails on to another address, such as a personal account or a colleague, with or without keeping a copy in your inbox. Spam is never forwarded.
Company details footerSet your company name, registration number and registered office once, and they’re added automatically to every email your team sends, as UK law requires for business emails.

Organise with folders & labelsSort messages into traditional folders or Gmail-style labels, search your whole inbox, and save drafts as you go.
Inbox rules & automationAutomatically sort incoming messages into folders or labels, mark them as read, add stars, and tidy up emails already in your inbox.
Snooze messagesHide an email until later today, tomorrow, the weekend, next week or a time you choose. It comes back to the top of your inbox on time, or sooner if a reply arrives.
Scheduled sendChoose when an email goes, such as first thing tomorrow. Until then it waits in Scheduled, where you can send it now, change the time or cancel it.
Built-in notesKeep notes and checklists beside your email, with pins, colours, search and reminders. Notes are private unless you share one with everyone who uses the mailbox.
Remind me if no replySet a follow-up reminder when you send an important email, and it comes back to your inbox if nobody replies within the time you chose.
Automated replies & templatesCreate professional email signatures, save reusable templates and schedule out-of-office replies.
Optional AI reply assistantSwitch it on in Settings and it drafts a reply to each new email for you to check. It runs on your own Cloudflare account and never sends anything. How your data stays private.
Everyday shortcutsIncludes Undo Send, full keyboard shortcuts, bulk selection, print-ready views and a pop-out composer window.

Team access & shared inboxesInvite colleagues to sign in with their own email address and open only the mailboxes you give them. Shared inboxes (e.g. sales@) appear in everyone’s sidebar, and each reply shows which colleague sent it.
Smart address bookAddress suggestions as you type, full contact details and email history on one screen, and easy contact import from Gmail, iPhone or Outlook.
Simple admin dashboardManage users, mailboxes, custom domains, routing rules, backups and bulk user imports from a spreadsheet, all from one admin panel.

Calendar & remindersMonth, week, day and list views, email invitations with RSVP tracking, one-click video calls, recurring events, and push notifications on mobile and desktop. More about the calendar.
Calendar sharing & syncShare calendars with your team, or make a team calendar everyone can see. See your schedule in Apple Calendar, Outlook and Google Calendar, and add calendars from a link, such as UK bank holidays.

Built-in spam filterActive protection against spoofed senders, brand impersonation, malicious links and newly registered domains, with a clear, plain-English reason for every flagged email.
Masked email aliasesCreate a unique alias whenever you sign up for a website. Approve or block new senders on first delivery, set expiry dates, and spot when a company leaks or sells your address.
Tracker & privacy protectionHidden tracking pixels are removed and other pictures load privately, so senders can’t tell when, where or on what device you opened their email.
Passkey sign-inSign in without a password using Face ID, Touch ID, Windows Hello or a security key, with an emailed code as a back-up.

Large file sharingSend attachments up to 3.5 MB directly, or share files up to 95 MB as encrypted download links. Protect links with a password and share them by WhatsApp or SMS in one tap.
Private file storageStore documents, photos and media in your own Cloudflare account. Upload files up to 5 GB, preview PDFs, pictures, videos and music in the app, and attach stored files to any email.

Progressive Web App (PWA)Pin KT8 Mail to your Windows taskbar, Mac Dock or phone home screen, with push notifications, live unread badge counts and mailto: link handling.
