Opt-in: betting terms
An opt-in is the deliberate action you take, usually ticking a box, pressing a button or entering a code, to join a specific promotion or to agree to receive marketing from a bookmaker or casino. Without it, the offer simply does not apply to your bets, however closely they match the terms. Operators set their own rules on when and how you must opt in, so the one detail that matters is whether the opt-in has to come before the qualifying bet.

How an opt-in works on a betting site
On most sites the opt-in button sits on the promotions page or inside the offer banner, and the bet slip will not remember it for you. If an acca insurance offer needs an opt-in and you place the five-fold first, that bet is normally outside the offer, even if it loses on the last leg.
Order is the whole game here.
Opting in also commits you to the offer’s terms. With a free bet that usually means the stake is not returned, so a €10 free bet at 3/1, an implied probability of 25%, pays €30 in winnings rather than €40. Read the minimum odds and expiry before you press the button, because some operators let you opt out afterwards and some do not.
Promotion opt-in versus marketing consent
The same word covers two different agreements, and readers mix them up regularly. The table sets them side by side, drawn from typical operator terms and the Gambling Regulation Act 2024.
| Point | Promotion opt-in | Marketing opt-in |
|---|---|---|
| What you agree to | Join one offer | Receive emails or texts |
| Where you meet it | Promotions page or banner | Registration form or settings |
| How long it lasts | Until the offer ends | Until you withdraw consent |
| Can you undo it | Varies by operator | Yes, via unsubscribe link |
| Legal basis in Ireland | Operator terms | Section 147, once commenced |
| Main risk | Bet placed before opting in | Offers arriving unasked |
What Irish law says about opt-ins
Section 147 of the Gambling Regulation Act 2024 says a licensee may not advertise by email, text or phone unless you have consented and can easily stop it. Section 157 separately bars inducements aimed at a specific person or group, while still allowing offers made to the general public.
Those advertising and inducement rules sit in Part 4 of the Act, which takes effect only when the Minister signs a commencement order for it. Until then, how opt-ins work is still set largely by each operator’s terms, so we read those terms first.
