Send one letter to multiple recipients with Multisender
Multisender
If you want to send the same letter to multiple people, the most annoying part is usually all the repeating. Multisender in PieterPost is built to make that faster: start one batch, add your recipients, and still keep control over what each person receives.
The value of Multisender is that you do not have to choose between speed and control. You can use one shared base while still personalizing each recipient with names, addresses, and extra fields. That makes it useful for a simple announcement as well as for a larger, cleaner mailing to a group.
These details are ready
[Recipient name]

The recipient below is only a starter example. In the real Multisender flow, you add multiple recipients afterwards, either manually, through CSV, or from Mailbook.
So your letter looks

When Multisender is useful
- • When you want to send the same announcement to family or friends, for example for a move, birth, or save-the-date.
- • When you want to send a thank-you letter or update to several people without rebuilding the letter each time.
- • When you need to send one core message to a list of recipients for work, school, a club, or an event.
- • When your addresses are already stored in Mailbook and you want to turn them straight into a batch.
- • When you want one shared message but still want to personalize it with a name or an extra field such as department, occasion, or reference.
Before you continue
- • Make sure every recipient has a complete address. During bulk import, only complete rows are used.
- • Use template mode when the base letter is the same for everyone and only names, addresses, or extra fields should change per recipient.
- • If you need different wording for each person, you can still manage multiple recipients in one flow while keeping separate versions.
- • For letters, US and non-US recipients cannot currently be combined in the same order.
- • If you already have an address list, adding recipients through CSV or Mailbook is usually faster than typing everything by hand.
How it works

2Add your recipients next: manually, through CSV, or from Mailbook.
3Review the preview for each recipient and fill in names, addresses, or extra variables where needed.
4Finish the batch in one checkout and send your letters in one flow.
Frequently asked questions
Can I send the same letter to multiple people?
Yes. With Multisender, you set up one batch and then add multiple recipients. You do not need to start from zero for every letter.
Can I still personalize the letter for each recipient?
Yes. In template mode, you use one shared base letter and automatically fill in things like name, address, and any extra fields per recipient. If you need truly different wording, you can still edit each recipient separately outside template mode.
Can I import recipients with CSV?
Yes. You can add recipients manually, upload a CSV, or first download a CSV template and fill it in. During bulk import, only fully completed rows are included.
Does Multisender work with Mailbook too?
Yes. If your addresses are already in Mailbook, you can send selected contacts directly into the letter or postcard flow, so you do not have to enter them again.
Can I also send multiple postcards at once?
Yes. The same concept works for both letters and postcards. This page starts with a letter example, but the same Multisender logic also exists in the postcard flow.
Can I combine US and non-US letter recipients?
Not yet for letters. The current flow blocks combinations of US and non-US letter addresses in the same order. Within one market, you can still send to multiple recipients in one batch.
