Attachments and their limits

Add files to a reply or new message, the size and number limits, and the files ZevInbox will not send.

Updated 2 min read

Add a file

In a reply or a new message, do any of these:

  • Select Attach files (the paperclip) and choose one or more files.

  • Drag files onto the message. It says Drop files to attach.

  • Paste an image, for example a screenshot. It is named Pasted image with the time.

Each file shows under your message while it uploads. Send says Uploading… and waits until every file is in.

If a file does not upload, it says Didn't upload. Select retry on the file, or remove it. A message cannot be sent while a file has not uploaded.

To remove a file, select the cross on it.

The limits

Limit

One file

25 MB at most

All files on one message

25 MB together

Number of files

25 per message

These match what Gmail and Outlook accept, so a message you send can be received.

Files ZevInbox will not send

To protect your customers, these are refused, with the reason:

Kind

Examples

Programs and scripts

.exe, .bat, .cmd, .msi, .js, .vbs, .ps1, .jar, .iso

Office files with macros

.docm, .xlsm, .pptm

Password-protected archives

A .zip with a password

Empty files

A file of 0 bytes

ZevInbox checks what a file really is, not only its name, so renaming a file does not get it through.

Forwarding

A forward carries the original message's attachments. Remove any you do not want to pass on before you send. They count towards the same limits.

Attachments you receive

Files a customer sends are listed under their message. Select an image to view it, or any other file to download it.

If a message was quarantined because of a dangerous attachment, the file shows as Blocked and cannot be opened. See Quarantine: review, release or request release.

On your phone

In the ZevInbox app, use Attach a file in the reply box. The same limits apply.
