A burofax is used when a communication must be more than a normal message. It is chosen when you need proof of content, date, sender, recipient and delivery attempt, especially in disputes, contract termination, debt claims, employment notices or formal legal requirements.
Today, many teams look for how to send a burofax online because they want the legal certainty of a formal notice without printing, queuing or managing postal paperwork. The key is not the word “burofax” itself, but the evidence package behind the communication: what was sent, to whom, when, through which channel and with what proof.
In this guide, you will see how to send a burofax step by step, when it makes sense, what mistakes to avoid and how Legalpin helps companies replace paper-heavy workflows with Buromail, certified email, electronic signature and certified SMS.
Need a digital alternative to postal burofax?
Legalpin Buromail certifies the content, recipient, date and evidence trail of your communication, without relying on paper delivery.
What is a burofax?
A burofax is a formal communication service traditionally used in Spain to send documents with proof. Unlike ordinary mail, a burofax is valuable because it can certify the sending, the recipient, the delivery or delivery attempt and, when requested, the exact content of the document.
That is why it is often used before or during a conflict. The sender wants to avoid a future discussion about whether the recipient was notified, what the message said or when the notice was sent.
In practice, a burofax is common for lease terminations, debt claims, breach of contract notices, employment communications, cancellation notices, formal warnings and legal requirements. For companies, the same evidentiary need often appears in commercial, HR, legal, collections and customer service workflows.
How to send a burofax step by step
1. Decide whether you need certified proof of content
Before sending anything, check what you need to prove. If you only need to prove delivery, a basic registered channel may be enough. If you need to prove the exact text and attachments, you need a certified content trail.
2. Choose the right channel
You can use a traditional postal burofax provider or a digital alternative such as Buromail or certified email. The right choice depends on the legal context, recipient, urgency, cost and the type of evidence you need to preserve.
3. Write the message clearly
A burofax should be direct, factual and easy to interpret. Include names, contract references, invoice numbers, dates, amounts, deadlines and the action you expect from the recipient. Avoid emotional language or vague accusations.
4. Attach the correct documents
If the notice refers to a contract, invoice, policy, quote, delivery note or previous communication, attach the relevant files. The evidence should connect the message with the supporting documents.
5. Review recipient details
Check the recipient’s postal address, email address or phone number depending on the channel. A strong legal notice can lose force if it is sent to the wrong person or an outdated address.
6. Send and keep the full evidence package
Do not save only the text of the message. Keep the certificate, delivery record, timestamps, content proof, attachments and any later response. This is what will matter if the communication is challenged.
Practical tip
Write the notice as if a third party will read it months later. The stronger the facts, dates and evidence trail, the easier it is to defend the communication.
Burofax, certified email, Buromail and registered mail: key differences
| Channel | What it proves | Best use |
|---|---|---|
| Postal burofax | Formal sending, delivery attempt and, if requested, certified content. | Traditional legal notices where postal delivery is preferred. |
| Registered mail | Usually delivery, but not always the exact content. | Low-risk notices where content certification is not essential. |
| Certified email | Sender, recipient, content, date and evidence of the email process. | Digital notices with attachments and fast delivery. |
| Buromail | Certified digital communication with content and traceability. | A digital alternative to burofax-style communications. |
| Certified SMS | Short certified notice sent to a phone number. | Urgent reminders, short notices and mobile-first recipients. |
For many companies, the most efficient setup is not choosing one channel forever. It is choosing the right certified channel for each risk level: Buromail for formal digital communications, certified email for detailed notices with attachments, certified SMS for urgent short messages and electronic signature when the recipient must accept or sign a document.
When should you send a burofax or Buromail?
- To terminate a contract or notify non-renewal.
- To claim unpaid invoices, fees or contractual debts.
- To notify a breach of contract and set a deadline to remedy it.
- To communicate employment notices, policy changes or disciplinary actions.
- To send formal warnings to clients, suppliers, tenants or partners.
- To prove that a document was delivered before a deadline.
- To create evidence before escalation to legal action.
If the recipient must actively approve something, combine the communication with electronic signature. If the message is short and time-sensitive, add certified SMS as a parallel channel.
Send formal notices without postal friction
Legalpin helps teams certify emails, send Buromail, request electronic signatures and keep evidence in one place.
5 mistakes to avoid when sending a burofax
1. Sending a vague or emotional message
The message should be clear and factual. A confusing notice can weaken your position because the recipient may argue that the request, deadline or consequence was unclear.
2. Forgetting to certify the content
Proof of delivery alone may not be enough. If the dispute is about what was communicated, you need proof of the exact content and attachments.
3. Using the wrong recipient details
Before sending, confirm the legal entity, contact person, address, email or phone number. This is especially important for companies, landlords, tenants and former employees.
4. Not keeping the evidence package
The certificate, receipt, attachments and timestamp should be stored together. If each piece is kept in a different folder or inbox, the evidence becomes harder to use.
5. Waiting until the deadline is too close
Formal notices often interact with legal or contractual deadlines. Send early enough to handle failed delivery, incorrect recipient data or follow-up communications.
Tip for debt claims
Include invoice number, amount, due date, payment method, deadline and consequence of non-payment. Then certify the message and keep the full evidence record.
How Legalpin helps with burofax-style communications
Legalpin is not a postal operator, and that distinction matters. If a contract, regulation or internal policy specifically requires a postal burofax, the company should use the required postal channel. But in many business situations, the real need is not paper delivery; it is a reliable evidence file that proves the communication, the content, the recipient, the date and the events around delivery. That is where Legalpin is most useful.
Legalpin helps companies manage formal notices through certified digital channels, especially when teams need to move faster than postal workflows and still keep a defensible record. Instead of relying on screenshots, normal email threads or manual folders, Legalpin creates a structured evidence trail around the communication.
Buromail for formal notices with certified content
Buromail is the closest Legalpin workflow to a burofax-style communication. It is designed for messages where the sender needs to certify what was sent, who it was sent to and when the communication was issued. This is particularly useful for debt claims, service cancellations, breach notices, contract termination, formal warnings and communications with customers or suppliers.
A typical Buromail file should include the message body, attached documents, recipient data, sending timestamp, certified content and the events associated with the communication. For a legal or compliance team, that is more useful than an isolated email because the record is already organized around proof.
Certified email when the communication includes detailed documents
Certified email works well when the recipient expects an email but the sender needs stronger proof than a normal inbox can provide. It is useful for invoices, policies, contract changes, account closures, service notices, customer complaints, supplier claims and operational communications with attachments.
The key value is content evidence. If the recipient later says the attachment was missing, the deadline was not stated or the amount claimed was different, the certified record helps show the version that was actually sent.
Electronic signature when the recipient must accept something
A burofax-style notice is often one-way: the sender notifies. But many workflows need an explicit acceptance. In those cases, electronic signature should be added to the process. This applies to settlement agreements, contract amendments, payment plans, HR acknowledgments, consent forms, service renewals and authorization letters.
The difference is practical: Buromail proves communication; electronic signature proves acceptance. When both are combined, the company can show what was sent, when it was received and how the recipient accepted the document.
Certified SMS for urgent short notices
Certified SMS is useful when the message is short, urgent and mobile-first. It is not the best channel for long legal arguments or multiple attachments, but it works well as a parallel reminder for payment deadlines, appointment changes, access notices, account warnings or urgent operational alerts.
For stronger workflows, teams can combine channels: send the full content through Buromail or certified email, then use certified SMS to alert the recipient that the formal communication has been sent.
Evidence custody for audits and disputes
The most overlooked part of a burofax-style workflow is storage. Many companies send a formal notice correctly but then lose the evidence across inboxes, local folders, CRM notes and screenshots. Legalpin helps centralize the communication record so it can be recovered later for audits, complaints, negotiations or litigation support.
For each formal notice, teams should be able to retrieve the sender, recipient, message, attachments, timestamps, delivery events and associated signature or response. That is the difference between “we sent it” and “here is the evidence file”.
Build the full evidence file, not just the message
Legalpin lets teams combine Buromail, certified email, certified SMS and electronic signature so each formal communication has the right proof for its risk level.
Which Legalpin channel should you use?
| Scenario | Recommended Legalpin channel | Evidence to preserve |
|---|---|---|
| Formal contract notice | Buromail | Notice text, contract clause, recipient, timestamp and attachments. |
| Debt claim with invoices | Certified email or Buromail | Invoice numbers, amount, due date, payment deadline and proof of content. |
| Recipient must approve a document | Electronic signature plus certified email | Signed document, signer identity, signature timestamp and delivery record. |
| Urgent short warning | Certified SMS | Phone number, message text, timestamp and delivery events. |
| High-volume operational notices | API-based certified email or SMS | Automated event logs, templates, recipient data and evidence certificates. |
Practical examples by department
Legal teams: breach of contract notice
A legal team can send a Buromail that identifies the contract, clause breached, facts, supporting documents, requested remedy and deadline. The evidence file should include the final text, attachments, recipient data and certified timestamp. If the case escalates, the team does not need to reconstruct the notice from scattered emails.
Finance teams: unpaid invoice claim
Finance can send a certified claim with invoice number, amount, due date, bank details, payment deadline and next step if payment is not received. For repeat debtors, certified email can document each stage of the collection process without turning every reminder into a postal workflow.
HR teams: employment notices and acknowledgments
HR can use certified channels for policy changes, documentation requests, remote work notices, disciplinary communications or payroll-related notices. When the employee must accept a policy or sign an acknowledgment, Legalpin can add electronic signature to close the loop.
Customer operations: service changes and cancellation notices
Customer operations teams can use certified email or Buromail to notify account closure, terms updates, non-payment suspension, cancellation deadlines or changes in service conditions. This helps reduce disputes where the customer claims not to have been informed.
Suppliers and procurement: missed obligations
If a supplier fails to deliver, misses a service level or sends incorrect documentation, procurement can send a certified notice with the order, SLA, delivery date, defect description and remedy deadline. The communication becomes part of the supplier file.
What a strong Legalpin evidence file should contain
For burofax-style communications, the file should be complete enough for someone outside the company to understand what happened. A strong record usually includes:
- The final message exactly as sent.
- All attachments included in the communication.
- Recipient identity and address, email or phone number used.
- Sender identity and organization.
- Sending date and timestamp.
- Delivery, access or notification events where available.
- Any electronic signature linked to the document.
- The certificate or evidence report generated by the platform.
This level of detail is what makes the workflow operationally useful. A manager can check the status, a lawyer can review the evidence, finance can continue a claim and compliance can audit the process without asking five different people for screenshots.
Conclusion
Sending a burofax is useful when a communication may later need to be proven. The essential point is to preserve a complete and reliable evidence trail: content, recipient, date, delivery events and attachments.
For companies that want a faster and more scalable digital workflow, Legalpin keeps the practical value of burofax-style communications through Buromail, certified email, certified SMS and electronic signature. That makes formal notices easier to send, easier to track and easier to defend.
Frequently Asked Questions
A burofax is traditionally a formal postal communication with proof. Certified email is digital and can certify sender, recipient, content, date and evidence events. The right option depends on the context, recipient and evidence requirements.
Buromail can be a strong digital alternative for many formal communications because it certifies content and traceability. Some situations may still require or prefer a postal channel, so the choice should match the legal and contractual context.
Include the parties, contract or invoice reference, relevant dates, facts, requested action, deadline and consequences. Attach supporting documents when they are part of the claim or notice.
A normal email may be useful for everyday communication, but it is weaker when you need to prove content, recipient, date and delivery events. For high-risk notices, certified email or Buromail gives a stronger evidence trail.
Legalpin helps preserve the evidence linked to certified communications, including content, recipient, date, sending events and related documents. This makes the record easier to retrieve if there is an audit, dispute or legal escalation.
