How much does it cost?

Calculate the price of a mail piece

The price of a postal API varies depending on two factors:

  • Type of printing and inserting
  • Type of postage
  • Optional services (Acknowledgement of receipt, Address page)

Add up the cost of printing and postage, and you get the price of a letter, printed, inserted, stamped and delivered to the post office. To keep your budget under control, you can also choose to send a letter only if an initial email has returned a negative status. Ask for us a quote.

Why use a REST postal mail API to send your physical mail?

With Efidem, your mail is printed, inserted, stamped and delivered to La Poste without any paper handling on your part. Thanks to our predefined mailing profiles and web platform, you gain in simplicity and efficiency.

Numerous options are available to adapt each mailing to your needs: color or black & white printing, single-sided or double-sided, choice of envelope type, economy or registered postage, and additional services such as address page or undelivered mail processing.

Our postal mail solution can also be integrated into your tools via API (REST, SMTP, FTP), to automate the sending of your transactional or administrative mail, without changing your habits. Mail or by post?

Our team will help you optimize your mailings, email, emailing or SMS and take full advantage of all the features available via our intuitive platform.


Sending paper mail remains essential in many contexts: administrative follow-ups, contractual documents, official notifications, sensitive communications, or mailings requiring a record. However, managing this mail manually, by printing it and then dropping it off at the post office, can quickly become time-consuming, expensive, and difficult to track. Using a REST API allows for the automation of this entire process, while preserving the legal and operational value of physical mail.

The first reason is time savings. With a postal mail API, it is no longer necessary to print documents, prepare envelopes, stamp mail, or travel. From your business software, your CRM, your ERP, or your internal platform, you can automatically trigger the sending of physical mail. The document is transmitted via the API, then handled for printing, stuffing, and shipping. This allows teams to focus on their core business rather than repetitive tasks.

The second reason concerns the reliability of the treatment. Manual submission can lead to omissions, address errors, delays, or a lack of visibility into what was actually sent. With a REST postal mail API, each mailing can be tracked, historized, and linked to a unique identifier. You know when the mail was requested, processed, shipped, and, depending on the available options, delivered. This traceability is particularly useful for customer service departments, administrative services, insurance companies, banks, local authorities, or businesses that send important documents.

The third reason is direct integration into your business processes. A REST API allows the connection of postal sending to your existing workflows: automatic generation of a letter after an unpaid invoice, sending a contract after validation, postal reminder after an unopened email, or triggering a registered letter according to a customer status. Physical mail then becomes an automated channel, just like email or SMS.

Finally, the postal mail API allows for better control of costs and volumes. Instead of managing mailings manually on a case-by-case basis, you centralize your workflows, standardize your templates, and precisely track your consumption. This is a particularly relevant solution as soon as volumes increase or mailings need to be regular.

In summary, using a REST API for physical mail allows for the modernization of a traditional channel, while also gaining speed, reliability, traceability, and operational efficiency.

In France, we are developing multi-channel technologies that optimize exchanges between companies and their contacts.
