Nº 01Why online

Buy a stamp, find an envelope, walk to the postbox.

The analogue part is the part where letters stall. That is the part FrankKi takes over.

No printer

Your iPhone is enough

Most people do not own a printer, and the copy shop is already closed. FrankKi handles printing, enveloping and mailing.

No trip

Posted from the sofa

No stamp to buy, no envelope to find, no walk to the postbox. You pick the shipping option and pay by card or Apple Pay.

Fully valid

A real letter

FrankKi prints and mails the paper letter. Whether the particular letter is legally sufficient or effective depends on its content, form, recipient and deadline.

Nº 02Reach

DACH

DE, AT, CH

Local postal tariffs in Germany, Austria and Switzerland.

Europe

FR, NL, GB, BE, LU, ES

Frequent questions

Answered briefly.

Do I have to print the letter or take it to a post office?

Neither. FrankKi prints it on real paper, puts it in an envelope and posts it. No printer, no stamp, no trip to a branch.

How long is my letter on its way?

Domestically a standard letter is delivered within 1 to 3 business days. Across DACH (DE, AT, CH) and six further European countries (FR, NL, GB, BE, LU, ES) the letter runs at local postal tariffs. To the rest of the world delivery typically takes 4 to 18 business days.

Is this legally valid?

FrankKi prints and mails your letter like a paper letter you post yourself. Whether the particular letter is legally sufficient or effective still depends on matters such as its content, form, signature, recipient and deadline. FrankKi does not provide legal advice.
