Looking for the most affordable way to send letters in bulk across the UK?
Whether you’re a small business, startup, or growing company, bulk mail can be more affordable than you think – especially when you use a UK mailing house like Selectabase.

📌 Quick Answer:
The cheapest way to send lots of letters in the UK is to use a mailing house that can access Royal Mail bulk postage discounts, provide targeted data lists, and handle print and fulfilment for you – all from under £0.49 per letter.

Why Postage Costs Matter for Businesses
Postage adds up quickly. If you’re sending 500 or 1,000 letters, every penny counts. Yet many businesses are still overpaying – or worse, wasting budget on generic, untargeted mail.
If you’re searching for:
- “cheapest way to send bulk mail in the UK”
- “where to find a UK mailing house”
- “how to send letters without doing it myself”
…this guide is for you.

2. Choose Efficient Formats (Postcards & Simple Letters)
You don’t need an expensive glossy brochure to get noticed. In fact, simple formats like:
- A5 postcards
- Standard A4 letters
…can achieve just as much impact at a fraction of the cost.
Examples:
- A5 postcards qualify as “letter” rate – no envelope required
- A4 letters under 100g can go 2nd Class cheaply
We help you pick the best format to reduce postage costs while keeping the impact high.

3. Don’t Print and Post In-House
If you’re currently printing and stuffing envelopes yourself, you’re not just wasting time – you’re likely paying more per item too.
Typical manual cost:
- 86p stamp
- 5p envelope
- 10–15p paper and ink
- Several hours of admin and post office queues!
Using Selectabase saves time, lowers cost, and ensures professional delivery. You also avoid waste by printing only what you need.

Sending 1,000 letters to random businesses or residential addresses? That’s a waste!
We help you send to:
- New local businesses
- Businesses by SIC code or industry –
- Targeted residential properties
