How it works

Step 2

Add your recipients

Build the list in a bulk order. The draft is saved as you go so you can come back to it.
Step 3

Choose postage and a print shop

Pick a class, compare shop prices and ratings, and review the total.
Step 4

Confirm and track

Pay once and follow the batch from printing to delivery in your dashboard.
Example scenario

Jess sends her first batch of 200 letters

This is an illustrative scenario to show how the platform works. It is not a customer testimonial.
Jess runs a small estate agency and has never sent a mailout herself. She needs to write to 200 past clients about a new service and wants to get it right the first time.

The problem

She doesn't know what order to do things in: the list, the letter, the postage, the printing. Every guide she finds is vague.She is anxious about wasting money on a mistake, like a bad address list or a layout that looks wrong when printed.Anyone should be able to run a professional mailout without specialist knowledge.

How LetterAPI helps

We know a first mailout can feel like a lot of unknowns. The process is simple once someone shows you the order of things.LetterAPI walks you through it: write or upload the letter, build the list, choose postage, compare UK print shops, preview the pages and check the total before paying. Your draft is saved as you go.

The plan, step by step

Step 1

Prepare the list and the letter

Jess cleans her client list, writes the letter and adds her return address.
Step 2

Choose postage and a shop

She picks second class, compares print shop prices and ratings, and previews every page.
Step 3

Confirm and watch it go

She pays once and follows the batch from printing to delivery.

What success looks like

Her first mailout goes out cleanly.
No surprises in cost or layout.
A repeatable process for next time.

What it costs to wait

A layout mistake printed 200 times.
Letters sent to out-of-date addresses.
Putting off the mailout again.
Send your first batchSee what it costs

Before you send: a quick checklist

Ten minutes of preparation saves most of the cost and stress.
Clean the address list: one row per person, no duplicates, valid postcodes.
Finalise the letter: check names, dates and any reference numbers.
Add your return address so undeliverable letters can find their way back.
Decide the postage: second class for routine mail, first class for deadlines, Signed For for proof.
Check the rules if it is marketing mail: data protection law and the Mailing Preference Service apply.

Common mistakes when sending in bulk

These are the issues that cost people time and money.
Sending first class when nobody needed the speed.
Posting to an out-of-date list and paying for letters that bounce.
Skipping the preview and finding a layout problem after hundreds are printed.
Splitting one mailing into many small orders and paying higher per-letter print charges.

How long does it take?

Timing depends on the print shop's posting cut-off and the Royal Mail class you choose. First class targets next working day for most UK addresses and second class two to three working days. Check the shop's cut-off before you order if the date matters.
