Write an email customers can understand
Use a recognizable sender name and a specific subject line. In the message, identify the business, briefly describe the reason for payment, state what the customer should expect after selecting the link, and provide a known way to verify the request. Avoid artificial urgency, vague warnings, or language that pressures the recipient to act without checking the details.
Display the link with descriptive text such as “review and complete the hosted payment page” rather than a shortened or disguised URL. If the provider uses a recognizable hosted domain, do not alter it to look like a different address. Customers who are unsure should be able to contact the business through a previously known channel before proceeding.
Email is the delivery channel, not the place to collect payment credentials. Never request cardholder data, passwords, bank credentials, complete account numbers, or secret API keys in the message or by reply.
