Is it safe to give my email address to enter a free competition online?
Free online competitions frequently collect email addresses to sell to marketers, enter you into subscriptions, or send phishing emails — read the terms carefully.
Last reviewed: 1 June 2026
Explanation
Entering an email in a free competition is low risk by itself, but many free competition sites exist primarily as data-collection businesses. Your email may be shared with hundreds of marketing partners, added to spam lists, or used to send convincingly branded phishing emails referencing the competition. Some sites auto-enrol entrants into paid subscriptions that are hard to cancel. Others exist solely to build targeted lists for subsequent prize fraud. Before entering, check the terms of entry to see who your data is shared with, whether entering constitutes consent to marketing, and whether there is a clear and genuine competition organiser.
Common red flags
- No clear organiser or company name associated with the competition
- Terms allow data to be shared with an undefined number of marketing partners
- Entering requires creating an account with payment details 'for identity verification'
- Competition runs only by email with no publicly verifiable draw
What to do now
- Read the privacy policy and terms before entering
- Use a secondary email address for competitions to limit spam to your main inbox
- Opt out of marketing consent if given the option
- Unsubscribe promptly from any marketing emails after entering
Frequently asked questions
How do I know if a competition prize draw is genuine?
Genuine prize draws are run by named, registered companies, comply with advertising standards, and publish draw results. Check the organiser's registration independently.
