One person. One entry.
Participants enter your giveaway by sending one WhatsApp message or email. Every entry is tied to a verified phone number or address, so you can count each contact once and reach the winner when the draw is done.
- No entry form
- One verified contact per entry
- Winners you can reach
Win the loudest weekend of the year.
Sign-ups by message. No form, no code.
Sendity is a sign-up widget for your website. Instead of filling in a form, your visitors send one short message via WhatsApp or email. Sendity checks who it came from and hands your site the name and the confirmed phone number or email address.
See how Sendity works →-
One message instead of a form Visitors tap send in WhatsApp or their email app. Nothing to type, no confirmation email to click.
-
Confirmed by the message itself The contact comes from the sender of the message, so typos and made-up addresses never reach your list.
-
Pay per confirmed contact Start with 1,000 free credits, no credit card. After that, prepaid packages with no subscription.
A prize is an incentive to cheat. A form that accepts any address makes it easy.
Throwaway addresses and bots
With a classic entry form, anyone can submit as many addresses as they like, including throwaway inboxes and addresses that do not belong to them. Bots fill the form in seconds. Your entry count grows, but the share of real participants shrinks.
A winner you cannot reach
A typo in an email address or phone number is only noticed after the draw, when the winner never answers. Then you draw again and explain the delay.
Verified at the moment of entry
With Sendity, participants send one short message from their own WhatsApp account or inbox. The entry only counts once Sendity has confirmed the sender. WhatsApp numbers are much harder to multiply than email addresses, so choose WhatsApp when one entry per person matters most.
Terms and consent stay yours
Sendity confirms the contact. Your participation terms, any marketing consent and your privacy information remain on your giveaway page, just as with a form.
Send once, you’re in.
Entering takes your participants about ten seconds.

Entry form or verified entry?
The difference shows on the day of the draw.
| Aspect | Classic entry form | With Sendity |
|---|---|---|
| Fake entries | Any address can be typed in | Only senders who control the account count |
| Multiple entries | A new address for every entry | Each entry tied to a verified contact |
| Reaching the winner | Typos surface after the draw | Contact confirmed at entry |
| Effort | Fill in the form, confirm by email | Send one message |
A fair draw, a reachable winner.

Questions about giveaways.
Does Sendity pick the winner?
No. Sendity confirms each entry’s contact. You run the draw with your own tools.
WhatsApp or email for a giveaway?
WhatsApp makes multiple entries much harder and is the quickest on mobile; a verified number uses 4 credits. Email uses 1 credit per address. You set the channel per campaign.
Do I still need participation terms?
Yes. Sendity replaces the entry form, not your terms, consent texts or privacy information.
