Lead with the recipient’s benefit
Write what the new customer actually receives, what action they must take and when it expires. Say what you receive too. A sample structure is: “If you join through my link and complete the stated steps, you may get [benefit]; I may get [reward]. Check the provider terms before joining.”
Check where the provider allows sharing
A “share” button is not permission to advertise everywhere. Some brands limit referrals to people you know, require consent or forbid commercial distribution. ClassPass’s personal referral programme, for example, has individual-use and consent restrictions. Check the current rules before posting a link on a public site.
Do not promise a result you cannot verify
Rewards can depend on location, account status or a changing campaign. Avoid claiming “guaranteed” credit if the provider displays a range or requires a later purchase. Link to the current terms and tell people to check the offer shown to them at signup.
Make a useful message
One concise explanation, a working link and a deadline are enough. Repeated unsolicited messages damage trust and may breach the programme rules. Keep personal conversations personal; for a public website, consider a programme that explicitly permits broader sharing or an approved affiliate route.
