A bulk letter sending service you control online

A good bulk letter sending service lets you stay in control: you decide the letter, the list, the postage and the print shop, and you see the cost first. Use the dashboard for one-off batches or connect the API to send letters automatically from your own systems.

When this is the right option

Teams that send occasionally

Teams that send regularly

Set up the same process each month and keep a record of every order.

Teams that want automation

Trigger letters from your own software through the API, and test in the sandbox first.

How it works

Step 1

Create a free account

Start a bulk order or generate an API key in the dashboard.
Step 2

Upload, preview and choose

Add the letter and recipients, pick postage and a print shop, and check the total.
Step 3

Send and track

Confirm the order and follow each letter until delivery.
Example scenario

Mo's startup wants reminder letters without a print vendor

This is an illustrative scenario to show how the platform works. It is not a customer testimonial.
Mo is a developer at a small subscription business. Customers with failed payments often ignore email, and the founders want a posted letter as a last step, ideally without managing a print supplier.

The problem

Mo has looked at agencies and mailing houses, but they need briefs, quotes and monthly commitments, and the volume is small and uneven.He is wary of getting stuck in a contract and worried about owning a fragile print integration on top of a busy roadmap.Letting customers know about a problem, politely and clearly, should not need a procurement project.

How LetterAPI helps

We know most sending services are built for big, regular volumes. If yours is small and uneven, you still deserve a straightforward option.Start with the dashboard for the first batch, then connect the API so your system creates orders itself. The sandbox lets Mo test without printing or paying, there is no monthly fee, and every order has a status he can follow.

The plan, step by step

Step 1

Try the dashboard

Mo sends a small first batch to see the preview, the print shop options and the total.
Step 2

Build in the sandbox

He creates test orders from the billing system with no printing and no cost.
Step 3

Go live

He switches to live orders, and letters go out when payments fail.

What success looks like

Failed-payment letters sent automatically.
No contract or minimum to manage.
A status for every order.

What it costs to wait

Weeks spent comparing agency quotes.
Customers who never see the email.
Revenue lost to failed payments.

Three ways to use a sending service

The right choice depends on who sends and how often.
The dashboard: upload, preview and send a batch yourself.
The API: your software creates orders automatically, for example a posted reminder after a missed payment.
A managed agency: a team handles design, data and approvals for a fee. More hands-on, usually quote-led.

What to look for in a letter sending service

Use this checklist when you compare.
Prices shown before you commit, with postage included.
No monthly fee or contract if you send irregularly.
A preview of the printed pages.
Order status you can follow, and a record of what was sent.
An API and a sandbox if you want to automate.
Choice of postage class, including Signed For.

Automating letters with the API

Post the letter and the recipient's address to the API and a UK print shop prints and posts it. The sandbox lets your developers build and test without printing or paying, and order status can be followed from your own code. The documentation covers the details.
