Send Letters OnlineReferral programme
Pass on the post.
Invite someone who still queues at the Post Office. When they sign up with your link and top up £20 or more, they get £5 Account Credit. When they have spent £10 of their own paid credit on letters we have posted, you earn £5.
For your friend
£5 or more
Account Credit with a first top-up of £20 or more. If the standard first top-up bonus is bigger, they get that instead. One offer, never both.
For you
£5 per friend
Once your friend has spent £10 of paid credit on letters we have posted. No monthly cap.
From link to letterbox.
Rewards follow real post, not sign-ups. Nothing is earned for an account alone. Read the full referral terms.
- 1
Share your private link
Every account has one link in the form sendlettersonline.co.uk/refer-a-friend?ref= followed by a 24 character code. Send it however you like.
- 2
Your friend signs up and claims
They create a new account after your link exists, then press Claim invite within 24 hours of signing up and before any letter or top-up.
- 3
They top up £20 or more
Their first top-up of £20 or more adds the friend bonus. A first top-up under £20 ends the referral.
- 4
They post £10 of paid letters
Once £10 of their own paid credit has gone on posted letters, and at least 7 days have passed since their qualifying first top-up, your £5 is awarded within about 15 minutes.
What your friend receives
Based on their first successful top-up.
| First top-up | Without a referral | With your link |
|---|---|---|
| Under £20 | Nothing | Referral ends |
| £20 exactly | £5 | £5 |
| £30 (any other amount from £20) | Nothing | £5 |
| £50 exactly | £10 | £10 |
| £100 exactly | £20 | £20 |
Welcome credit has no cash value and can be removed if the original top-up is refunded or disputed.
When your £5 is earned
Promotional credit is spent first and never counts.
Refunded or cancelled letters do not count. Your £5 also waits until at least 7 days after the friend's qualifying first top-up, checked every 15 minutes.
Redeem from £50, your way.
Referral earnings are kept separate from your spendable Account Credit until you choose what to do with them.
Account Credit, instantly
Move earnings into your Account Credit straight away and pay for letters at checkout without a card.
Cash payout request
Our team reviews each request and contacts your verified account email to arrange payment. We never ask for bank details in the app, and no payout is guaranteed until reviewed.
- At least 7 days after the friend's qualifying top-up, checked every 15 minutes.
- Refunds and disputes reverse the linked reward. Future earnings offset any negative balance.
- Your dashboard shows progress, never your friend's name or email.
The fine print, in plain English.
- Your friend must create a new account after your referral code exists.
- They claim the invite themselves, within 24 hours of signing up, before any letter or top-up.
- One referrer per account. Referring yourself, or accounts you control, is not allowed.
- Payments made before the invite was claimed are never counted retrospectively.
- No rewards for sign-ups alone and no monthly cap.
Questions
How much does my friend get?
Your friend gets £5 Account Credit when their first top-up is £20 or more. If the standard first top-up bonus would be larger (£10 for exactly £50, £20 for exactly £100), they get that instead. The two offers never stack.
When do I earn my £5?
After your friend has spent £10 of their own paid Account Credit on letters that have been posted. Promotional credit, including their welcome bonus, is treated as spent first and does not count. Refunded or cancelled letters do not count. With a £20 top-up and £5 welcome credit, that means £15 of posted letters before you qualify.
Does my friend have to be new?
Yes. They must create a new account after your referral code exists, and claim your invite within 24 hours of signing up, before sending any letter or topping up. Each account can have only one referrer, and you cannot refer yourself.
Do I earn anything when a friend just signs up?
No. Sign-ups alone never earn a reward. Rewards depend on a real top-up and real posted letters.
How do I redeem my earnings?
Once you have at least £50 available, choose Account Credit (added instantly and spendable on letters) or a cash payout request. Cash requests are reviewed by our team and paid manually to the contact details on your verified primary account email. No payout is guaranteed until it has been reviewed.
Why can my available balance be negative?
If a friend's payment is refunded or disputed, the reward linked to it is reversed. If you had already redeemed it, your available balance can go below zero. Future referral earnings offset it first.
Is there a monthly limit?
There is no monthly cap on referral earnings. Your friend's welcome credit has no cash value and can be removed if their original top-up is reversed. See the Referral Programme Terms for full conditions.
Can my friend see my details, or me theirs?
No. Your dashboard shows the status and progress of each referral without your friend's name or email address.
