Large Attachments

Gaggle Mail has always supported attachments but up until now, it’s had an occasionally annoying 10MB maximum size limit.

We’re delighted to let you know that you can now send single attachments of up to 35MB and a maximum total message size of a whopping 100MB!

As you can see from the table below, most email services have a maximum incoming message size of around 20-25MB.


Email client Sending and inbound size limits
Apple Mail (iCloud) 20 MB
Gmail 25 MB
Outlook/Office 365 20 MB, with up to 150 MB in Office 365
ProtonMail 25 MB
Yahoo 25 MB
Zoho Mail 20 MB


With this in mind, whenever an email is sent over your group which will result in an outgoing message of over 10MB, we strip the attachments from the message and replace them with links to the attachment files which are hosted on our servers. Learn more about this here.

Being able to seamlessly send attachments of up to 100MB will make sharing resources across your group even easier without. If you have any feedback in this feature or anything else on Gaggle Mail, please let us know.
