Help with fax document types

The Sundial Telecom Email to Fax service supports file formats generated by most recognised computer applications and we are continuously updating the formats we do support. There are some important things to remember when sending fax documents, whatever the document type:

  • If you attach multiple documents they will be processed in no particular order. If you require the pages to be transmitted in a particular order you should create a single, multi page document. If you require a coversheet, this should be page one of your multi page document.
  • We do not transmit any of the content in the email body as a fax, so this cannot be used as a coversheet. Please delete any content from the body of the email, such as signature files. If these arrive on our platform as attachments, they will be processed as a separate fax document and you will be charged to send them.
  • Where possible, format the document as A4 which will achieve the best results.
  • DO NOT send password protected documents – we will be unable to process them.
  • The document we receive from you will be converted to TIFF format, the industry standard fax file type, so the resultant fax may not be identical to the original document.
  • Documents that are very colourful and graphically heavy will take longer to transmit and therefore cost more to send.

Currently we support the following file formats:

Comment

| Microsoft Word *.doc, *.rtf, *.txt, *.wri, *.log, *.docx These are amongst the most common types of documents we receive for faxing and have proven to be very reliable

| Text Document *.txt A very simple text file format with limited formatting options. Ideal for simple text only faxes.
