WhatsApp or email. You set the channel.
In the Sendity app you decide for each campaign which channel gets verified. Visitors see exactly that one way.
Verifies a mobile number. Scan or tap, and WhatsApp opens with the message ready to send.
SMS works too. It reaches people without WhatsApp but is less secure, so you decide per campaign whether to allow it.
Verifies an email address. One click opens the mail app with the email ready to send. No confirmation link.
Ready for your next campaign.

What does Sendity do?
Sendity replaces sign-up forms with a single message. Visitors send a short code via WhatsApp or email, Sendity confirms the sender, and your campaign receives their name and contact.
Do visitors need an app?
No. They use WhatsApp or their email app, which they already have.
Can I offer email only?
Yes. You set the channel for each campaign in the Sendity app.
How does Sendity get onto my page?
With the WordPress plugin as a block, or with a short snippet for any other page.
What data do I receive?
The name and the verified phone number or email address of the person who signed up.
What does it cost?
You start with 1,000 free credits. A verified email address uses 1 credit, a verified phone number 4 credits. When you need more, you top up a package, and your credits never expire.
