Do I Need an Opt-out for GDPR?

✅ If you’re only emailing someone in direct connection with the purpose of the form submission, for example:

• Sending them a receipt,
• Confirming a booking,
• Responding to an enquiry,
• Delivering a requested download,

Then you’re likely processing that data under the lawful basis of “contract” (Article 6(1)(b) UK GDPR), not “consent.”

👉 In this case, you do not need to provide an opt-out because you’re fulfilling a service the user actively requested. You’re not doing unsolicited marketing, you’re completing the transaction.

❗However, if you plan to use their data for marketing purposes such as:

• Sending newsletters,
• Promotions,
• Follow-up offers,
• Sharing data with third parties,

Then the lawful basis would likely be “consent”, and you must:

• Obtain clear, specific consent at the point of collection, and
• Offer an opt-out (like an unsubscribe link or contact method).
