How to Create a Campaign Entry Form -- Fields, Duplicate Prevention, and Winner Contact

Last updated: July 17, 2026

If you reuse a normal registration-form template for a giveaway or contest, important decisions are often left until after the form is live.

A campaign entry form has three additional concerns: can one person enter more times than intended, how will you explain the use of personal information for the campaign, and how will you contact winners without sending the wrong message to every entrant?

This guide covers the fields, duplicate-entry controls, privacy-purpose wording, winner communication, and operating schedule. For the broader map of form types, start with the Form Creation Guide.

Quick Answer: Decide These Three Things First

Decision	What to define	Useful setting
Duplicate-entry policy	How many entries one person may submit	One per email, one per browser, or no limit
Purpose of personal-data use	Whether the data is limited to the contest and drawing	Entry rules and consent copy
Winner communication	Who will be contacted and by when	Tags, filters, and individual or batch email

The operating flow is simple when it is decided in advance:

Entry received -> Duplicate check -> Drawing -> Winner contact

If these decisions are postponed, the form may need to be rebuilt after entries have already arrived.

Required Fields by Campaign Pattern

The right fields depend on the campaign.

Campaign pattern	Required fields	Optional fields	Watch out for
Giveaway or prize draw	Name, email, agreement to the entry rules	Phone, shipping address	Ask for a shipping address later if only winners need it
Social campaign	Name or nickname, email, social account name, confirmation checkbox	Post URL	Treat follow or post confirmation as self-reporting unless you have a separate verification process
Campaign plus document request	Name, company, email, separate agreement to each purpose	Department, phone	Keep campaign consent and document-request consent as separate checkboxes

Do not ask for more personal information than the prize or operation requires. Extra required fields increase the entry barrier and reduce the number of completed entries.

Prevent Duplicate Entries

FORMLOVA lets you choose the duplicate-entry policy for each form.

Method	How it works	Suitable for
Email restriction	Accept only one entry from the same email address	One-entry giveaways and campaigns with a clear participant identity
Browser restriction	Accept only one entry from the same browser	Lightweight campaigns that want to minimize email collection
No restriction	Accept repeated entries	Campaigns that intentionally allow multiple entries during a period

Email restriction is stronger for valuable prizes. Browser restrictions can be bypassed by changing browsers or using private browsing, so do not treat them as a perfect identity check.

You can ask FORMLOVA in chat:

Limit this campaign entry form to one entry per email address.

If multiple entries are intentionally allowed, state that rule in the entry terms and decide how repeated entries will be handled during the drawing. Duplicate prevention is available on the free plan.

State the Purpose of Personal-Data Use

For a campaign entry form, make it clear how the submitted information will be used. A practical example is:

We will use the personal information you provide only to conduct this campaign, contact selected winners, and deliver prizes.

If the same form also requests a document or subscribes someone to a newsletter, use separate checkboxes for those purposes. Combining everything into one consent sentence can lead to the feeling that entering a campaign automatically opted someone into marketing email.

The Contact Form Privacy Consent Guide covers shorter consent examples and the relationship with a privacy policy. This article focuses on limiting the purpose to the campaign, drawing, winner contact, and prize delivery.

This is a practical design guide, not legal advice. Confirm the final entry rules and consent wording for your own organization and campaign.

Contact Winners with a Defined Schedule

Make the winner state visible in the response data before the notification day. In FORMLOVA, you can tag selected entries:

Add the “Winner” tag to these five entries and the “Not selected” tag to the rest.

Then filter the response list:

Show only entries with the “Winner” tag.

And send only to that filtered group:

Send the winner notification email only to people with the “Winner” tag.

Batch delivery to a filtered group is available on the Standard plan and above. Preview the recipient count and message before sending so that a winner email is not accidentally sent to every entrant. If non-winners will not receive individual messages, state “only selected winners will be contacted” in the entry rules.

Set the entry deadline, drawing date, winner-contact deadline, and shipping or participation date before publishing. Writing those dates into the rules gives the operations team a clear schedule and gives entrants a predictable expectation.

Social Media Campaigns: What to Check

For a follow-and-post campaign, the form will generally collect a self-report:

Social account name
Checkbox confirming that the participant followed or posted as required
Post URL (optional)

FORMLOVA does not automatically verify an external social account's follow state. Keep the checkbox as a self-report and perform a manual check before the drawing. Making the post URL optional keeps the entry barrier lower while leaving a useful clue for later review.

Tell entrants in advance how the campaign will be checked. If a missing URL invalidates an entry, make that rule clear instead of surprising people after the draw.

Build the Campaign Form in FORMLOVA

Use this order:

1. Choose fields for the campaign pattern.
2. Choose email restriction, browser restriction, or no restriction.
3. State that personal information is used for the campaign purposes described.
4. Configure the entry confirmation email.
5. Monitor entry count and duplicate flags during the campaign.
6. Tag and filter winners after the drawing.
7. Contact winners and export the participant list as CSV or Excel.

On the Standard plan and above, you can customize the confirmation email. Telling entrants when winners will be contacted reduces support questions. The monthly email limits are 100 on Free, 1,000 on Standard, and 10,000 on Premium.

For a high-volume campaign, combine response logging with Slack and Google Sheets using the official Slack and Sheets logging workflow. Response data can also be exported for a separate drawing process.

FAQ

How many entries should one person be allowed?

For a giveaway or prize draw, one entry per person is the usual starting point, implemented as one entry per email address. If the campaign intentionally allows one entry per post or per day, state that rule and choose no restriction.

Can I contact only the winners?

Yes. State that only selected winners will be contacted, then filter by the Winner tag before sending. This makes the rule understandable to entrants and keeps the operation focused.

Can the entry period be controlled by the form?

Yes. Set an acceptance deadline so the form closes automatically. If the campaign has a capacity limit, use a response limit so entries close when the capacity is reached.

Can FORMLOVA verify an Instagram follow automatically?

FORMLOVA does not automatically verify an external social follow state. Collect a confirmation checkbox and review the account manually before the drawing.

Does FORMLOVA run the random drawing itself?

The response list can be exported as CSV or Excel for a separate drawing process. After the result is decided, use tags to mark winners and filter them for communication.
