This article provides the answer to a common inquiry on the possibility to increase the maximum email size supported by FaxMaker Online in order to send faxes that are larger than 20MB.
According to Attachments Types Supported by GFI FaxMaker Online, the total size of the email including any attachments must not exceed 20MB.
FaxMaker Online works by converting each attached file into a fax file before the converted fax pages can be transmitted to the recipient. The limitation to convert and transmit a maximum of 20 Megabytes (20MB) is implemented on the backend and is not configurable therefore the total file size of all attachments and the email content cannot exceed this threshold. Note, however, that certain mail servers may have an even lower email size limit in which case only send faxes that do not exceed this mail server limit.
See Sending Faxes From Your Email Using FaxMaker Online for some additional considerations to be aware of when sending faxes from your email.
