Email to Fax

To send a fax from email, compose a message from your email.

In the To: field, type the 11 digit fax number (ex. 18885551212) followed by @send.mfax.io. This feature

will only work from an email address associated with an active account in Documo.

Note: It is important to always use an 11 digit fax number when formatting the email. This means you need to include a "1" for faxing any number in the USA or CANADA.

Faxes sent via email are limited to 10 recipients or less. Attempting to send to more than 10 recipients will

result in an error.

When sending a fax from email you can attach multiple documents types (see below). You can attach a

single document or multiple documents (varying formats is fine) and they will be rendered, converted to a

faxable format, and sent to your destination fax number. Maximum file size is 25MB. The maximum

amount of file attachments is 25.

Once your documents are attached, simply hit Send.

Adobe Acrobat Documents (PDF)

Microsoft Office Files (DOC, DOCX, XLS, XLXS, PPT, PPTX)
