How does it work?
Dematerialize your mailings
Efidem offers an api envoi courrier, a simple and complete solution for dematerializing the sending of administrative postal mail while taking advantage of professional rates that respect your budget.
Your mail is sent by a mail API without you touching a sheet of paper: we take care of the printing, enveloping, franking and forwarding to the post office on your behalf.
Printing,
envelope stuffing
Your letters are printed on high-quality recycled paper.
Envelope size automatically adjusts to the number of pages per envelope.
Large account postage
Benefit from low professional rates.
Optimize your postage budgets without volume commitments or additional machines.

How much does it cost?
Calculate the price of a mail piece
The price of a postal letter by API varies according to 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.
