Sending and receiving faxes

How do I send and receive my faxes?

To send a fax, we send the document as an attachment from any email to the address, where xxxx is replaced by the recipient fax number.

eComFax incorporates mechanisms to ensure security and avoid spam. Therefore, to send faxes from the email, the user has to specify a four-digit numeric PIN at the beginning of the “Subject” field. This PIN will be received when you sign up for the service and can also be configured from the “Settings” menu of the eComFax website. This PIN is common to all your number (s).

Example: Assuming the user’s PIN is 1234 the subject of the message would be: “1234This is the attachment”. The first four digits are removed from the subject and validated with the PIN of the user sending the email. In the event that an email is sent without this PIN or is invalid the email will be rejected.

You can also send from the web, accessing from your browser on your mobile, tablet or desktop computer to the following address: https: // / user / Home / NewFax.

To receive faxes, you must provide the sender with the fax number that eComFax will provide at the time of contracting the service. The fax will arrive to you by email.

Your fax number also appears in the “Home” window of the User’s Web.

Can there be a space between the attachment and the PIN Code?


How do I insert a cover page in the email?

eComFax automatically generates a standard cover page. If you require an automatic cover page, send the fax to the email (note faxp (front page) instead of fax) and indicate the notes you want to appear on the cover in the “Subject” field of the email itself.

What if I send a fax without attachment and without a cover?

If you send a fax without an attachment and without a cover, it will be an error since there is nothing to send.

Each month we give new credits according to the contracted plan. These credits do not accumulate from one month to the next. If you need more credits for a specific month, you can top up your balance by clicking “Reload” in the “Start” menu of the eComFax user website. This credit needs to be consumed within a year.

How do I know that I am running out of credits?

You will receive a notification email when you have consumed 80% of your balance. There is the possibility of receiving a “notification by SMS”. This notification is activated from the section “Configuration of the User’s Web”. The sending of these notifications by SMS consumes credits.

My subscription plan includes some pages of sending and receiving faxes. What happens if I do not have enough credits to receive faxes?

Faxes are received but will not be delivered until you top up with the necessary credits.

When you want to receive a Fax and you do not have enough credits to do so in your subscription, it will take them from your sending credits. eComFax will save the faxes up to a maximum of 30 days.

When sending a fax you receive a notification saying that the fax could not be sent due to insufficient balance.

This occurs because you do not have a sufficient balance and you would have to top up the balance or wait until the end of the month so that your subscription is renewed automatically and you are assigned new credits.
