Sign-ups without forms. Verified in one message.
Every form field is a chance to give up, mistype or make something up. With Sendity, visitors send one prepared message by WhatsApp or email instead, and the contact you receive is the one that message came from.
- No fields to fill in
- Verified at sign-up, not later
- Phone number or email, per campaign
Sign up without a single field.
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 sign-up form asks people to type their own contact details correctly, honestly and right away. Each of those three is a place where sign-ups get lost.
Abandoned half-way
On a phone, every extra field is more typing. People who meant to sign up close the tab before they reach the button, and you never learn they were there.
Mistyped contacts
One wrong letter in an address or one missing digit in a number, and the access link, the voucher or the reminder goes nowhere. The form accepted it anyway.
Fake entries and bots
Made-up addresses, second accounts for a second chance and scripted sign-ups fill your list with contacts nobody can reach. CAPTCHAs slow down real people more than bots.
Confirmation emails that never arrive
Double opt-in checks the address after the fact. When the confirmation lands in spam or gets lost, a real sign-up is lost with it.
More fields for more details
Company, position, phone: every detail sales would like is one more field, and every extra field costs sign-ups. So forms ask for little, and the details are missing later.
The approach: the message is the sign-up
Instead of typing a contact, visitors send one prepared message with a short code. Per campaign you choose phone numbers or email addresses: numbers are verified via WhatsApp, with SMS as an optional, less secure fallback; addresses by the DKIM signature of the email. Your page receives the sender’s contact and name as verified.
Details from the email signature
For email campaigns you can switch on AI extraction at no extra charge. Where the sent email carries a signature, Sendity takes company, position and phone from it, without asking for a single field.
From visit to verified contact in one message.
The same three steps for a webinar, a newsletter, a giveaway or an account.
Add the widget where the form was
With the WordPress plugin, the Laravel package or one snippet on any other site.
Visitors send one message
The message is prepared with a short code. On a computer, a QR code opens it on the phone.
Your page gets the verified contact
As a signed result your site checks and passes on to your newsletter, webinar or CRM tool.
Sign-up form or sign-up by message?
What changes when the contact comes from the sender instead of a text field.
| Aspect | Sign-up form | With Sendity |
|---|---|---|
| Typing | Name, address or number, often more | None, one tap on send |
| Typos | Noticed when the first message bounces | Not possible, the contact comes from the sender |
| Fake entries | Any made-up address is accepted | Only contacts that sent the message |
| Verification | Later, by confirmation email or SMS code | In the same step, on your page |
| Company and position | More fields, fewer sign-ups | Optional, from the email signature |
One approach, every sign-up.
Wherever people leave a contact today, a message can replace the form.
Fewer drop-offs
Nothing to type on a small screen, so more people who start also finish.
Contacts you can reach
Every number and address is verified, so your messages arrive.
More details, no fields
The sender’s name always comes with the contact; for email, company and position can come from the signature.

Questions about sign-ups without forms.
Do my visitors need WhatsApp?
No. Per campaign you choose whether phone numbers or email addresses are verified. Email works with any inbox. Phone numbers are verified via WhatsApp by default; you can allow SMS as a fallback, which is less secure.
Do I still get a name?
Yes, always: the sender’s name comes with every verified number or address, and your page can greet them by it. For email campaigns, AI extraction can add company, position and phone from the signature, where there is one at no extra charge; it is unlocked with your first top-up.
Does this replace double opt-in?
Yes. Double opt-in proves that the person signing up controls the email address. A code they actively send back proves exactly that, in the same step instead of through a confirmation link, and for phone numbers too.
What does it cost?
You start with 1,000 free credits. A verified email address uses 1 credit, a verified phone number 4 credits. Attempts that do not verify cost nothing.
