Contest and Giveaway Tools Compared
A giveaway can be run from a spreadsheet and a social post, right up until a few hundred people enter and you need to check entries, collect consent and pick a winner fairly. Dedicated contest and giveaway tools handle that heavy lifting. This comparison looks at Gleam, ViralSweep and Woobox, what each is built for, and how to choose one for your next campaign.
Key takeaways
- Contest tools handle entry forms, bonus entries, duplicate checks, consent capture and random winner selection, which are hard to do well by hand.
- Gleam, ViralSweep and Woobox overlap a lot, so choose on the entry types you need, where the contest will live and how you will use the email list afterward.
- No tool writes compliant rules for you. Official rules, disclosures and prize laws vary by country and state, so check the official guidance.
- Run a small test contest first, and check current features, pricing and privacy policies before you commit.
Late December is a busy time for contests. Some shops run a "new year, new you" prize draw, others use a January giveaway to grow an email list before spring. Whatever the reason, the moment entries start arriving you face the same practical questions. How do people enter? How do you stop one person entering fifty times? How do you prove the winner was picked fairly? And what happens to all those email addresses afterward?
That is what contest and giveaway tools are for. This guide is not about prize ideas or post wording; it is about the software that runs the contest behind the scenes. A quick note: this article is general information, not legal advice. Promotion and prize laws differ between countries and states, so check the official rules where you operate and ask a lawyer for anything large or unusual.
What a contest tool actually does
At its simplest, a giveaway tool gives you an entry form, a list of entrants and a button to pick a random winner. The useful ones go further.
- Entry methods. Email sign-up, answering a question, uploading a photo, visiting a page, referring a friend and similar actions, often with bonus entries for extra steps.
- Embedding. A widget you place on your website, a hosted landing page, or both.
- Fraud and duplicate checks. Spotting repeat entries, fake email addresses and obvious bot activity.
- Consent and rules. Checkboxes for marketing consent, a link to your official rules and a record of what each person agreed to.
- Winner selection. A random draw from eligible entries, with a record you can keep in case anyone asks.
- Integrations. Sending entrants to your email platform or exporting a clean list.
Common mistake
Treating the tool as the whole compliance plan. A neat entry form does not make a contest legal. You still need clear official rules, honest disclosure of any partners or sponsors, and an entry route that fits the prize laws where your entrants live.
The three tools at a glance
All three have been popular with small brands for years. Their feature lists change often, so treat the descriptions below as a starting point and confirm the details on each provider's site.
Gleam
Gleam is widely used for giveaways that reward many different actions. Its strength is flexible entry options: you can stack several ways to enter, each worth a set number of entries, and display the campaign as a widget on your own site or on a hosted page. It suits brands that want to grow several channels at once, such as an email list, a social following and website visits, in one campaign. Gleam also offers other apps for things like capturing emails and showing galleries, which some teams use alongside their contests.
ViralSweep
ViralSweep focuses on sweepstakes, contests and instant-win promotions, with an emphasis on list building and ecommerce. It is often chosen by online shops that want entrants to flow straight into their email and text marketing, and it supports referral style bonus entries that reward people for sharing. If your main goal is a bigger, cleaner email list rather than social follows, it is worth a close look.
Woobox
Woobox offers a broad set of interactive campaigns: giveaways, photo and video contests, polls, quizzes and instant-win games, plus tools for picking winners from comments on social posts. It suits businesses that want variety, for example a holiday photo contest one month and a quiz the next, or that mostly run giveaways through comments on their social posts.
Pro tip
Before you compare features, write down the one number that defines success for this contest: new email subscribers, user photos collected or visits to a new product page. Then pick the tool that makes that one outcome easiest. Everything else is a bonus.
Comparison template: score the tools for your campaign
Use this table as a worksheet. Fill it in after you have tried each tool's free plan or demo. The entries below are a made-up example for a small gift shop planning a January email-list giveaway.
| Criteria | Why it matters | Gleam (example notes) | ViralSweep (example notes) | Woobox (example notes) |
|---|---|---|---|---|
| Entry methods we need | Email, referral, photo upload | Covers all three in test | Covers email and referral well | Strong for photo contests |
| Email platform connection | Entrants must reach our list with consent | Connected in test | Connected in test | Export only on plan we tried |
| Fit with our monthly budget | Example limit: $50 a month | Check current plans | Check current plans | Check current plans |
| Our score out of 5 | Team vote after testing | 4 | 4 | 3 |

How to choose: a step-by-step process
- Define the goal and the audience. Who should enter, where they live and what you want from them. A contest open to people in several countries is more complex than one limited to your own.
- Pick the format. A random prize draw, a skill-based contest judged on merit, or an instant-win game. Each format has different legal rules in different places, so check before you choose.
- List required entry methods. Keep it short. Three or four entry options is usually plenty; too many feels like homework.
- Check consent handling. Make sure the tool lets you separate "enter the contest" from "join our mailing list," so people can enter without subscribing if your local rules require it.
- Test on a phone. Most entrants will be on mobile. Enter your own test contest and see how it feels.
- Run a draw rehearsal. Add a few test entries, pick a winner, then export the records. Make sure you can explain the process if an entrant asks.
- Decide, then document. Note why you chose the tool, so next year's campaign starts from a known setup.
Rules, disclosures and consent
Whatever tool you pick, a few legal basics apply. Rules change, so treat these as a starting checklist and confirm the details with official sources.
Official rules
Publish clear rules covering who can enter, the start and end dates, how to enter, the prize, how and when the winner is chosen and contacted, and who is running the promotion. In the US, sweepstakes rules vary by state, and many require that people can enter without making a purchase. In the UK, the line between a lawful prize draw and an unlicensed lottery depends on how entry works, so check current guidance before asking for any payment or purchase.
Endorsements and labels
If you ask entrants to post about your brand to earn entries, those posts are promotional. In the US, FTC rules require clear disclosure of material connections in endorsements, and in the UK the ASA and CAP Code require ads to be clearly labeled. A simple hashtag or line such as "entry for a giveaway" helps, but check the current guidance for the wording regulators expect.
Email consent and privacy
Entry forms collect personal data. In the UK and EU, PECR and GDPR rules on consent apply to marketing emails, so get clear opt-in consent to marketing that is separate from entering. In the US, CAN-SPAM requires a clear unsubscribe option and a valid physical postal address in commercial emails. If your contest page uses tracking pixels for retargeting, you also need cookie consent where required and a clear privacy notice.
Reviews and photos
Never offer entries in exchange for positive reviews. The FTC's 2024 rule bans buying fake or incentivized positive reviews in the US, and similar concerns apply elsewhere. For photo contests, get permission before reusing entrants' photos in your marketing, and say in your rules how you plan to use them.
Example
Marta runs a small candle shop and plans a January giveaway for three gift boxes. She sets up the contest in her chosen tool with two entry options: enter with an email address, or share a referral link for bonus entries. A separate, unticked checkbox asks whether entrants want her newsletter. Her rules page names the closing date, explains the random draw and says no purchase is needed. When the contest closes, she exports the entries, removes test and duplicate entries, runs the draw in the tool and saves a screenshot of the result with the date. Only people who ticked the newsletter box go into her email platform. (This is an illustrative example.)
Running the contest smoothly
Once the tool is chosen, a little discipline makes the difference between a contest that grows trust and one that creates support headaches.
- Keep the prize relevant. A prize linked to what you sell attracts people who might buy later, rather than prize hunters who will unsubscribe next week.
- Set a short run. One to three weeks keeps energy up and makes reminders easier to plan.
- Watch entries daily. Look for spikes from suspicious sources and use the tool's fraud filters before the draw, not after.
- Announce the result as promised. Contact the winner the way your rules say, and give them a clear deadline to respond.
- Welcome new subscribers properly. Send a friendly welcome that explains who you are, so new contacts do not forget why they signed up.
Common mistake
Adding every entrant to your newsletter by default. Beyond the consent issues in many countries, it fills your list with people who wanted the prize, not your emails. Unsubscribes and spam complaints follow, which can hurt delivery to your real customers.

Frequently asked questions
Do I need a giveaway tool for a small contest?
Not always. For a very small draw with a few dozen entries, a form builder and a spreadsheet can work. Once you expect hundreds of entries, bonus entries or several channels, a dedicated tool saves time and gives you better records.
Which tool is the cheapest?
Pricing and plan limits change often, and they depend on features such as branding removal and integrations. Check each provider's current pricing for the specific features you need rather than comparing headline plans.
Can I run a giveaway only through social media comments?
Yes, and some tools help pick a random winner from comments. Check each platform's own promotion rules too, since social networks set their own requirements for contests on their sites.
