Fax vs email

The ultimate comparison of two transmission methods

Researched and verified
Expertly compiled

Both have strengths - depending on the use case

Email is unbeatable for everyday communication. Fax, however, excels in legal reliability, proof of delivery and acceptance by authorities. For important, time-bound or legally relevant documents, fax is often the better choice.

The choice depends on the recipient and the importance of the document.

When to use fax, when to use email

Fax for terminations

For time-bound terminations, the fax transmission report provides recognised proof of delivery.

Fax for authorities

Many authorities accept faxes as an official communication channel - emails often do not.

Email for everyday communication

For normal business correspondence and internal communication, email is more practical.

Email for large files

Large files, presentations or archives are better sent by email.

Fax or email - which transmission method is right for you? Both have their place, but for different purposes.

In this comparison, we show you when to use fax and when email is the better choice.

The strengths of fax

Fax offers some unique advantages that email cannot provide:

  • Automatic proof of delivery: The transmission report documents successful delivery.
  • No spam filters: A fax cannot be blocked by mistake.
  • Higher acceptance: Authorities and businesses often accept fax as official proof.
  • Direct transmission: No interim storage on third-party servers.

The strengths of email

Email is indispensable in daily life - and for good reason:

  • Free of charge: No per-message cost.
  • Large attachments: Files up to several GB are possible.
  • Archiving: Emails remain in the mailbox permanently.
  • Reply function: Easy conversations are possible.

Conclusion: both have their place

For everyday use, email is exceptionally convenient. But when it comes to legal reliability, meeting deadlines or communication with authorities, fax is often the better choice.

With online fax services like FaxMonkey, you can send faxes just as quickly and easily as emails - with the added advantage of documented proof of delivery.

Frequently asked questions

Does fax have more evidentiary value than email?

Yes, in most cases. The fax transmission report automatically documents successful transmission with a timestamp. An email read receipt can be refused by the recipient, and emails can end up in the spam folder.

In legal disputes, a fax transmission report is therefore often rated more highly.

Can an email end up in the spam folder?

Yes, that is a common issue. Spam filters can block legitimate emails without the sender or recipient noticing. A fax cannot "end up in spam" - it is either delivered or not, with a corresponding error message.

Which costs more - fax or email?

Email is free if you already have an email account. Online fax at FaxMonkey costs 1,00 € for the first page and 0,25 € for each additional page.

For occasional important documents, this price is a small expense for added security and proof of delivery.

When should I use fax instead of email?

Fax is particularly recommended for:

  • Time-bound terminations
  • Legally relevant documents
  • Communication with authorities
  • When proof of delivery is important
  • When the recipient prefers fax
