A bulk letter mailing service for UK businesses

A bulk letter mailing service takes your letter and a list of addresses, then prints, folds, envelopes and posts every copy for you. LetterAPI does that through UK print shops and Royal Mail, with no monthly fee and the full price shown before you pay.

What a bulk mailing costs, all in

Mailing houses usually quote on request. Here are the estimated all-in figures for a single-page letter in a standard envelope, postage included.
Batch size2nd Class, per letter2nd Class, batch total1st Class, per letter1st Class, batch total
100 letters£1.72£172.00£2.70£270.00
500 letters£1.72£860.00£2.70£1,350.00
1,000 letters£1.72£1,720.00£2.70£2,700.00
5,000 letters£1.72£8,600.00£2.70£13,500.00
Estimates use the platform-average print and envelope charge, the same maths as the pricing calculator. Each print shop sets its own charges, so your final price may differ. For more than 5,000 letters a month, ask us for custom pricing.

When this is the right option

Agencies and property managers

Send notices and statements to every household you manage without a post room.

Finance and admin teams

Post statements, reminders and policy changes on a schedule, without someone printing by hand.

Membership and community groups

Reach members who read paper, and pay only for the batch you send.

How it works

Step 1

Add your letter and recipients

Write it in the editor or upload a PDF, then add every recipient's address to a bulk order. Drafts save as you go.
Step 2

Compare print shops

See prices and ratings for UK print shops and check the A4 preview.
Step 3

Send and track

Confirm the order. Each letter is printed, enveloped and handed to Royal Mail, and you follow progress in your dashboard.
Example scenario

Claire's accounts team stops using the post room

This is an illustrative scenario to show how the platform works. It is not a customer testimonial.
Claire is finance manager at a 30-person engineering firm. Each month the team sends around 400 statements and reminders by post, and it has always meant a day of printing, folding and stamping.

The problem

The job falls to whoever is free, errors creep in, and a mailing house would mean quotes, briefs and minimums.She feels guilty about pulling people off real work, and nervous about trusting an outside service with customer letters.Good finance teams should spend their time on cash flow and customers, not on envelopes.

How LetterAPI helps

We know a routine mailing should not need a project team. You want it done properly, quickly, and without a contract.LetterAPI is a self-service mailing service: you upload the letter and the list, preview the pages, compare UK print shops, and pay per letter. For 500 letters on second class the estimate is about £1.72 each, all in, shown before you commit.

The plan, step by step

Step 1

Upload the monthly letter and list

Claire's team adds the statement text and customer addresses to a bulk order, and the draft is saved.
Step 2

Check and compare

They preview the A4 pages, compare print shop prices and ratings, and review the total.
Step 3

Send and keep the record

They confirm once and follow the batch from printing to delivery in the dashboard.

What a bulk letter mailing service should include

When you compare services, check that the basics are covered, not just the headline price.
Printing: your letter printed on A4, in colour or black and white depending on the print shop.
Enveloping: each letter folded and sealed in an envelope with the recipient's address.
Postage: handed to Royal Mail on the class you choose, from £0.91 second class.
Proof: a preview before you pay and a status for every order after you send.
A clear total: printing, envelope, postage and fees in one price, before you commit.

What to ask any mailing service before you sign up

Prices vary, but surprises usually hide in the terms.
Is there a minimum number of letters per batch?
Is there a monthly or set-up fee?
Is postage included in the price you see?
Can you preview the printed pages before paying?
Can you see where each letter is once it has been sent?
