What bulk letters really cost
Most bulk mailing sites hide their prices or leave postage out. These are the all-in figures: postage, printing, envelope and our platform fee, for a single-page letter in a standard envelope.| Batch size | 2nd Class, per letter | 2nd Class, batch total | 1st Class, per letter | 1st Class, batch total |
|---|---|---|---|---|
| 50 letters | £2.16 | £108.00 | £3.14 | £157.00 |
| 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 |
When this is the right option
Small business mailouts
Announce a price change, chase unpaid accounts or invite customers back. A posted letter gets read when an email gets skipped.Landlords and managing agents
Send the same notice to every household in a block or portfolio, each with its own address, without a day of printing and stuffing.Charities, clubs and campaigns
Reach members and supporters who do not read email, and send only as many letters as your budget allows.How it works
Step 1
Create a free account
Sign up, start a bulk order and your draft is saved as you go, so you can come back and finish it.Step 2
Write your letter and add recipients
Write it in the editor or upload a PDF, add your return address, then add every recipient's address.Step 3
Compare shops and check the price
See per-letter prices and ratings for UK print shops, preview the A4 pages and review the total.Step 4
Send and track
Confirm the order. Each letter is printed, enveloped and handed to Royal Mail, and you follow it from your dashboard.Example scenario
Sam runs a small gym and is raising membership prices next month. Sam wants members to hear about it in writing, and wants all 300 of them to get a proper letter, ideally without paying a monthly fee for a mailing service.Sam needs 300 letters posted before Friday
This is an illustrative scenario to show how the platform works. It is not a customer testimonial.The problem
Sam has no print room. Printing 300 letters, folding them, finding envelopes and stamping each one would take most of a day, and the gym still has to open.Sam feels uneasy about the price rise and worries members will feel blindsided. A sloppy, hand-stuffed mailout would make that worse.Customers deserve to hear about changes that affect their wallet properly and on time, and a small business should not need a big budget to do that well.How LetterAPI helps
We know that sending one batch of letters should not mean signing up to a contract. That is why there is no monthly fee: you pay for the letters you send and nothing else.LetterAPI hands your letters to UK print shops, who print them, put them in envelopes and pass them to Royal Mail. You see the full price, including postage, before you pay. For 300 letters on second class that is about £1.72 per letter.The plan, step by step
Step 1
Write once, add your members
Sam writes the letter in the editor, adds a return address and adds each member's address to a bulk order. The draft saves as Sam goes.Step 2
Compare shops and check the price
The shop comparison shows prices and ratings for UK print shops. Sam previews the A4 pages and sees the total before paying.Step 3
Send and follow along
Sam confirms the order. Each letter is printed, enveloped and handed to Royal Mail, and the dashboard shows progress.What success looks like
Every member gets an addressed letter on time.
Sam gets the day back and only pays for the letters sent.
Questions come from informed members, not surprised ones.
What it costs to wait
A day lost to printing and stuffing envelopes.
Members hear about the rise from someone else first.
Paying a monthly fee for a service used once.
Ways to send bulk letters, compared
Which route is cheapest depends on how many letters you send and how often.| Option | Cost shape | Your effort | Best for |
|---|---|---|---|
| Print and post it yourself | Paper, ink and envelopes plus postage per letter | High: print, fold, stuff, stamp and queue | Fewer than about 20 letters |
| Royal Mail Business Mail | Discounted postage for sorted, barcoded volume, with minimum volumes | High: you print, envelope and prepare mail to Royal Mail's rules | Large, regular runs with your own print setup |
| Online mailing service with a monthly plan | Monthly fee plus per-letter charges, postage often extra | Low | Steady, predictable volume every month |
| LetterAPI | No monthly fee, one all-in price per letter | Low: upload, preview, send | One-off and irregular batches from a handful to thousands |
What is free, and what is not
Nobody can post bulk letters at no cost. Royal Mail charges for every item, and someone has to pay for paper, toner and envelopes. Be wary of any page that promises otherwise.Here is the honest split with LetterAPI:Free: creating an account, the letter editor and the page preview.
Free: no monthly fee, no subscription and no contract.
You pay per letter: Royal Mail postage (from £0.91 second class, £1.80 first class), the print shop's printing and envelope, and a small platform fee.
You see the total before you pay, so there are no surprises.
How to bring the cost down
The biggest savings come from a few choices you make before sending.Choose second class when the letter is not urgent. Postage is roughly half the first class price.
Reach 100 letters in one batch. Printing and envelope charges are lower from 100 letters, so one batch of 100 costs less per letter than two of 50.
Keep the letter to a single page. Every extra page adds printing cost.
Compare print shops. Shops set their own prices, and the shop comparison shows who is cheapest for your run.
Clean your address list first. Duplicates and wrong postcodes waste a letter each.
Only add Signed For when you need proof of delivery. It adds to the postage on every letter.
Prepare your address list
A clean list saves money and gets more letters delivered. Use one row per recipient with a name, first line of address, town and postcode. Check postcodes and remove duplicates before you upload.If the letters are marketing, check the rules before you send. UK data protection law and the Mailing Preference Service apply, and you should not mail people who have opted out. This is general information, not legal advice.Put a return address on the letter so an undeliverable one can find its way back to you.What happens after you press send
The print shop you chose prints each letter, puts it in an envelope and hands the batch to Royal Mail. You follow each order from print to mailing to delivery in your dashboard. Delivery times follow the Royal Mail class you picked, and a shop's posting cut-off time decides which day the batch goes out.HM

Frequently asked questions
Not entirely. Postage, printing and envelopes always cost money. What is free is the account, the editor and the preview, and there is no monthly fee. You pay only per letter sent, and you see the total before you pay.
As an estimate, about £1,720.00 on second class (£1.72 per letter) or about £2,700.00 on first class (£2.70 per letter) for a single-page letter. The print shop you choose sets its own printing and envelope charge, so check the price in your order.
Second class postage, a single-page letter and a batch of at least 100 letters keep the cost per letter lowest. Comparing print shops helps too.
You can send a handful or thousands. Printing and envelope charges fall once a batch reaches 100 letters. For more than 5,000 letters a month, contact us for custom pricing.
Yes, each recipient gets a letter addressed to them. For fully merged letters where the content changes per person, use the API to generate each one from your own data.
It depends on the print shop's posting cut-off and the Royal Mail class you pick. First class targets the next working day for most addresses and second class two to three working days.
Yes, but marketing mail has rules on data protection and opt-outs, including the Mailing Preference Service. Check them before you send. This is general information, not legal advice.
