VsisMail

VsisMail is the official mail app for VSIS Email Server customers — professional email on your company's own domain (you@yourcompany.com).

Sign in with your email address and mailbox password and you're ready. No server settings, no extra account.

A CLEAN, CLEAR INBOX • See attachments right under each email • Swipe to archive or delete, with Undo • Select multiple emails: mark, star, move, delete • Server-side search that handles accents correctly • Instant new-mail notifications — sender and subject only, never the message content • New mail appears automatically while the app is open

READ MAIL SAFELY • Messages are rendered in an isolated view — no scripts run • Remote images are blocked by default to stop tracking — one tap to show them • Report spam, report phishing or block a sender right from the message

PREVIEW FILES IN-APP • View PDF, Word, Excel, PowerPoint and images without downloading • Swipe between attachments, zoom into photos • Save files or open them in another app

FAST COMPOSING • Recipient suggestions, text formatting, file and photo attachments • Drafts save automatically — never lose a half-written email • Schedule send: long-press the Send button • Ready-made templates (quotes, meeting invites, minutes, invoice reminders…) plus your own • Automatic signature

SYNCED EVERYWHERE Mail, folders and read status sync directly with the mail server — exactly what you see in webmail and desktop mail apps.

AND MORE • Multiple mailboxes on one device • Light and dark themes • 7 languages: Tiếng Việt, English, Français, 中文, Русский, 日本語, 한국어 • Signature, auto-reply, time zone, block list and password settings

NOTE: VsisMail works with mailboxes hosted on VSIS Email Server (including mailboxes bundled with VSIS hosting plans). Don't have one yet? Contact VSIS or your company administrator to get a mailbox.
