The entry method determines who enters, how many enter, what data you collect, and which compliance obligations apply. Choosing the right method, or combination of methods, is one of the main decisions in sweepstakes design.
This guide covers the major entry methods: how each works, when to use it, what it costs, and what compliance requirements come with it.
Entry Methods at a Glance
| Method | Friction | Data Capture | Cost to Run | Works as Free Entry? |
|---|---|---|---|---|
| Online form | Low | High (name, email, custom fields) | Low | Yes |
| Social media action | Very low | Low (handle only) | Low | Varies — see below |
| SMS / text-to-enter | Very low | Medium (phone number) | Moderate | Yes at standard rates; offer web or mail-in too |
| Mail-in entry | High | Low (name, address) | Low | Yes — most traditional |
| Purchase + receipt upload | Moderate | High (purchase data + contact) | Moderate-High | No — needs separate AMOE |
| Product code entry | Low-Moderate | Medium (code + contact info) | Higher (printing) | No — needs separate AMOE |
| QR code scan | Very low | Medium (varies by destination) | Low-Moderate | Varies |
| In-person / event entry | Moderate | Medium (form at event) | Low | Yes (if free event) |
| App-based entry | Moderate | Very high (app data + entry) | High (app required) | Varies |
Online Form Entry
The most common entry method for digital sweepstakes. Participants visit a landing page and complete a form to enter.
How It Works
Participant visits the entry page, fills in required fields (typically name, email, and any custom fields), agrees to official rules, and submits. The system records the entry, sends a confirmation, and adds the entrant to the drawing pool.
Advantages
- Rich data capture: Collect email addresses, demographic information, survey responses, and marketing opt-ins in a single interaction
- Scalable: Handles thousands to millions of entries without manual processing
- Trackable: Analytics on entry sources, conversion rates, and drop-off points
- Low cost: The software subscription is usually the main cost; check whether your tool charges per entry or per contact
- AMOE-eligible: A web form with no purchase requirement is a valid free entry method
Disadvantages
- Needs a landing page or an embed on your site
- Form length inversely correlates with entry rate — more fields = fewer entries
- Susceptible to bot entries without proper validation (CAPTCHA, email verification)
Optimize form length for your goal
For the most entries, ask for name and email only; each extra field adds friction. For qualified leads, add 2-3 targeted fields (company size, role, interest) and expect fewer, better-qualified entries. Match form length to your campaign goal.
Social Media Entry
Participants enter by performing a social media action: following an account, liking a post, commenting, sharing, or using a hashtag.
How It Works
Brand posts a sweepstakes announcement with entry instructions. Participants complete the specified action(s). At promotion end, the brand collects eligible entries and selects a winner — typically using a comment picker tool or by exporting engagement data.
Advantages
- Lowest friction: Actions most users already perform (like, follow, comment)
- Built-in distribution: Comments and engagement expose the promotion to participants' networks. Platform rules limit what you can ask for: Meta bars requiring or rewarding shares, reposts and tags
- Audience building: Direct follower growth as an entry mechanic
Disadvantages
- Limited data capture: You get a username, not an email address or contact details
- Consideration questions: Follows, likes and comments are generally not consideration, but an off-platform entry form is good practice
- Platform dependency: Each platform has its own promotion rules. See our social media legal requirements guide
- Documentation challenges: Proving who liked/followed/commented requires screenshots or API data, and API access can cost money (X's API has been pay-per-use since February 2026)
Social entry alone is not enough for data capture
If your campaign goal is email acquisition, social media entry doesn't achieve it — you get handles, not emails. Use social posts for visibility and link to an online form for the actual entry. This captures emails while still using social distribution.
For detailed platform-by-platform guidance, see our social media contest guide.
SMS / Text-to-Enter
Participants text a keyword to a short code or toll-free number to enter.
How It Works
Promotional materials display: "Text WIN to 12345 to enter." Participant sends the text. The system responds with a confirmation and may request additional information (name, email) via reply texts or a link to a web form.
Advantages
- Very low friction: Nearly everyone has a phone. No app download, no form to fill out.
- Mobile-first: Suits audiences who mainly engage on mobile (events, retail, radio promotions)
- Phone number capture: Useful for SMS marketing and verification, with the right consent
- Free-entry treatment: Standard message rates are generally treated like postage, but premium-rate charges are consideration. Offer a free web or mail-in option alongside text entry.
Disadvantages
- Requires a short code or toll-free number. Dedicated short code leases from the U.S. Short Code Registry cost $500-$1,000 a month, plus provider and messaging fees
- Limited data capture in the initial interaction (phone number only)
- TCPA consent required before sending marketing texts, and that consent can't be made a condition of purchase
- Carrier registration and filtering rules can affect deliverability
Revup doesn't accept keyword texts as entries. Its SMS tools send transactional texts, such as entry confirmations, after someone enters through a Revup form. See the text-to-win sweepstakes guide for setup and compliance.
Mail-In Entry
The original sweepstakes entry method — and still the most universally accepted AMOE.
How It Works
A common format: the participant handwrites their name, address, phone number, and email on a 3x5 card and mails it to the address in the official rules, with one entry per stamped envelope. Mail-in entries must have the same odds as every other entry.
Advantages
- Widely accepted as a valid AMOE: The cost of a stamp is generally not treated as consideration
- Low implementation cost: A mailing address and manual processing
- Predictable volume: Most entrants still use the digital method, so mail-in processing stays manageable
Disadvantages
- Manual processing required (opening, recording, entering into system)
- Slow turnaround (mail transit + processing time)
- Not real-time — entries may arrive after the drawing if mailed near the deadline
- Limited data capture and no digital tracking
Purchase-Triggered Entry
Participants earn entries by making a qualifying purchase and submitting proof — typically a receipt photo, product code, or loyalty card scan.
How It Works
Customer buys a qualifying product, then submits proof of purchase (receipt upload, code entry, barcode scan). The system validates the purchase and records the entry. A separate free AMOE must be available for non-purchasers.
Advantages
- Direct sales attribution: Every entry represents a verified purchase
- Rich purchase data: Retailer, product, price, date, location — all from receipt uploads
- Repeat engagement: Multiple purchases can earn multiple entries if the rules allow, but "buy more, get more entries" is higher risk. Free entrants must never be capped below buyers
Disadvantages
- Must have AMOE: Purchase entry alone = illegal lottery. A free entry path with equal odds is legally required, and selling entries or a pretext product can still be illegal gambling even with one
- Higher friction: Receipt upload is more effort than a simple form fill
- Validation complexity: Receipt promotions need OCR or manual review plus fraud checks
- Higher cost: Receipt processing technology and administration
Revup's purchase sweepstakes take a different route: they award entries automatically from eligible Shopify orders, so there are no receipts to upload, and you can add a free entry form to your storefront. Revup doesn't process retail receipts. For complete guidance, see our purchase sweepstakes guide.
Revup
Build Revup sweepstakes, photo and video contests, instant wins, Shopify purchase sweepstakes, and forms with configurable entry fields, rules templates, and participant reporting.
Product Code Entry
Unique codes printed on product packaging, inside caps, under labels, or on in-pack inserts.
How It Works
Customer purchases a product, finds the unique code, and enters it on the promotion website or via SMS. The system validates the code (one-time use), records the entry, and may reveal an instant win result.
Best For
- Beverages (under-the-cap codes)
- Packaged food (in-pack or on-pack codes)
- Any physical product where packaging can carry a code
Advantages and Disadvantages
| Advantage | Disadvantage | |
|---|---|---|
| Fraud prevention | Unique codes prevent duplicate entries | Code generation and printing add cost |
| Verification | Each code validates a real purchase | Lost/damaged codes create customer service issues |
| Engagement | Code entry creates an interactive moment | Requires customer to find and enter the code |
| Instant win compatible | Codes can trigger instant win results | Algorithm complexity increases |
QR Code Entry
Participants scan a QR code on packaging, displays, or print materials. The code directs them to the entry page — prefilled with campaign data and optionally with a unique identifier.
Best For
- In-store and point-of-purchase displays
- Event activations and booth traffic
- Product packaging (bridging physical product to digital entry)
- Print advertising and direct mail
Choosing the Right Entry Method
| Campaign Goal | Primary Entry | AMOE | Why This Combination |
|---|---|---|---|
| Email acquisition | Online form | None needed (the form is free) | Form captures email with no purchase required |
| Social growth | Social action + form link | Online form (no social required) | Social action drives follows; form captures data |
| Purchase lift | Receipt upload or eligible online orders | Online form or mail-in | Purchases earn entries; AMOE provides an equal free path |
| Mobile engagement | SMS text-to-enter | Online form or mail-in | SMS is quick on mobile; form is the free web option |
| In-store traffic | QR code → form | None needed if the form is free | QR bridges physical to digital |
| Instant win engagement | Online game (spin/scratch) | None needed if play is free; mail-in or form if play needs a purchase or code | Free play is itself free entry |
Combine entry methods deliberately
Many sweepstakes pair a primary method aligned with the campaign goal (for example, purchase entry) with a free online form, and sometimes mail-in as well. Every method feeds the same drawing with equal odds per entry.
AMOE Requirements by Entry Method
Every sweepstakes needs a free way to enter. If the primary method is free, it already is that free entry. If it requires a purchase or payment, you need an alternative method of entry (AMOE) with equal odds. Here's how common primary methods compare:
| Primary Entry | Is It Free? | AMOE Required? | Recommended AMOE |
|---|---|---|---|
| Online form (no purchase) | Yes | No — it's already free entry | N/A — the form IS the free entry |
| Social media (follow/like) | Generally yes | Not usually; good practice | Online form (no social required) |
| Purchase + receipt upload | No (requires purchase) | Yes — mandatory | Online form + mail-in |
| Product code | No (requires purchase) | Yes — mandatory | Online form + mail-in |
| SMS text-to-enter | Yes at standard rates; premium rates are consideration | Offer one alongside text entry | Online form or mail-in |
| In-person / event | Depends on event | If event is paid: Yes | Online form + mail-in |

Frequently Asked Questions
Can I combine multiple entry methods in one sweepstakes?
Yes. Many sweepstakes pair a primary entry method aligned with the campaign goal with one or two free methods. All entry methods feed into the same drawing pool, and entries from all methods must have equal odds of winning.
Which entry method gets the most entries?
Low-friction social actions (follow, like, comment) tend to produce the most raw entries. Online forms produce more useful entries because they capture contact data, and purchase entries come from actual customers. Choose based on your goal, not just volume.
Does requiring email verification reduce entries?
Verification can add friction while helping establish control of an email address or phone number. Test completion and support needs for your audience. Verification does not eliminate every bot, duplicate, or eligibility problem.
How do I prevent fraud across entry methods?
Layer multiple controls: email verification, IP monitoring, CAPTCHA, device fingerprinting, and manual review of suspicious patterns. For purchase entries, add receipt validation and duplicate detection. No single control is sufficient. Revup sweepstakes include CAPTCHA, IP limits, and configurable fraud-prevention levels; see sweepstakes fraud prevention for a full approach.
