B Mail bulk mailing in Switzerland

FlyerMail supports address preparation, printing, envelope handling, and mailing windows. Larger mailing volumes can be prepared in a structured way and brought into dispatch reliably.
Start requestPrepare your order
Prepare your own mailing list
Your list needs a complete Swiss delivery address for each recipient: name or company, street and house number, postcode and town. Check duplicate and incomplete entries. You do not need to reformat an existing list in advance; we agree the required file structure before production.
Allow time for approval and postal delivery
Include time for data preparation, corrections, printing and posting. The postal delivery period starts after handover to Swiss Post. For invitations or limited offers, also tell us the event or promotion date.
Minimum quantity and delivery time for B Mail bulk mailings
Postal conditions apply from the time the items are handed to Swiss Post. Printing, data preparation and envelope insertion must be completed beforehand.
At least 350 items in the same price category
Swiss Post requires at least 350 items posted at the same time, in the same price category and from the same sender. If you use several formats, this condition must be checked for each price category.
By the sixth working day
Swiss Post delivers by the sixth working day after posting, Monday to Friday. This is not delivery on a fixed date. For an event, allow a margin between posting and the last useful arrival date.
The finished envelope counts
The format, thickness and total weight of the finished item determine its postal category. We do not automatically fold a flat A4 flyer. Mention extra sheets or inserts in your enquiry.
Plan express separately
For addressed mailings, the express option in the calculator applies A Mail instead of B Mail bulk mailing. The total includes your selected printing option. Print approval and postal handover must fit the confirmed date; B Mail itself does not become an express service.
Key points for your campaign
For plannable mailing volumes
B-Post is useful when delivery does not need to happen the next day and the campaign can be prepared with realistic lead time.
Align data and production
Address lists, print files, inserts, envelope handling, and the mailing window need to fit together before production starts.
For budget-conscious campaigns
With larger quantities, the mailing model affects both budget and planning. B-Post can be a suitable option for this.
Choose the mailing type
For postcards, selfmailers and letters, enter the recipient count from your address list. Addressing and the processing required for the product are included. No area selection is needed.
