After you tap send, QuickFax immediately begins transmitting your fax over the internet to the recipient's fax machine or digital fax inbox. Transmission typically takes 1–3 minutes per page, depending on the recipient's equipment.
You'll see a live status page showing each stage: Queued → Sending → Delivered. Once the recipient's machine successfully receives your fax, QuickFax marks it delivered and sends you an email confirmation with the date and time — important documentation for legal or medical deadlines.
If the recipient's line is busy, QuickFax retries automatically. If the fax still can't be delivered — for example, the number is disconnected or the machine is out of paper — you'll be emailed and you won't be charged. You can then retry sending, verify the number, or contact the recipient.
Is it legally valid?Yes. Faxes sent from online services like QuickFax are legally equivalent to faxes sent from a physical machine. Courts, government agencies, insurance companies, and medical providers all accept them. QuickFax's delivery confirmation provides the transmission documentation some organizations require as proof of timely filing.
