Forms & Newsletter: Capturing Leads and Subscribers
Point any form on your hosted site at BillionBiz to capture leads with no backend code, then collect subscribers and send tracked email broadcasts.
Any form on your hosted site — contact, quote request, support — can send its submissions to BillionBiz with no backend code. Submissions are stored, emailed to you, and listed in your admin panel.
Not just hosted sites
Marketing → Newsletter and Marketing → Form Submissions also collect signups and messages from your main storefront — the newsletter field in your store footer and the message form on your Contact page — tagged with source Store. Everything below about the Subscribers/Compose/Campaigns tabs and the Submissions list applies to those the same way it applies to hosted-site and landing-page captures.
Add a form to your site
Point your form at your site's submission endpoint. The label in the URL (contact below) lets you tell multiple forms apart in your inbox.
<form action="https://api.gateway.billionbiz.in/api/v1/hosting/public/forms/contact/submit" method="POST">
<input name="submitter_name" placeholder="Your name" />
<input type="email" name="submitter_email" placeholder="Your email" />
<textarea name="message" placeholder="Message"></textarea>
<!-- spam honeypot: keep hidden, leave empty -->
<input type="text" name="_honeypot" tabindex="-1" autocomplete="off" style="display:none" />
<button type="submit">Send</button>
</form>
A copy-paste JavaScript (fetch) version is also available in the connect guide inside the admin panel. Any extra fields you add are captured and included in the notification email.
Where submissions go
Screen: Go to your site → Submissions tab, or Marketing → Form Submissions (called just Form Submissions in the classic sidebar; the new admin sidebar's Marketing group doesn't list a Submissions entry — open it directly at /marketing/submissions) for every site's submissions in one place.
- Every submission is saved and appears in Marketing → Form Submissions (searchable, filterable, with a detail view and CSV export) and in the site's own Submissions tab.
- You receive an email notification for each submission.
- In Settings, set the recipient email for the site — and optionally route specific forms to specific addresses (e.g.
support→ support@,quote→ sales@).
Limits & protection
- Up to 50 fields per submission.
- A hidden honeypot silently discards bot spam.
- Submissions are rate-limited per visitor.
Email delivery
Notification emails are sent through your own SMTP credentials, configured once under Plugins → SMTP. If SMTP isn't set up, submissions are still saved — but the email won't be delivered. Configure SMTP before relying on form emails.
Newsletter & subscribers
Collect subscribers from your hosted sites (and your landing pages), then send broadcasts and track who opens them — all from Marketing → Newsletter.
Collect subscribers
Add a signup form to your site pointing at the subscribe endpoint:
<form action="https://api.gateway.billionbiz.in/api/v1/hosting/public/newsletter/subscribe" method="POST">
<input type="email" name="email" placeholder="you@example.com" required />
<input type="text" name="_honeypot" tabindex="-1" autocomplete="off" style="display:none" />
<button type="submit">Subscribe</button>
</form>
New subscribers are added to your list (tagged by source — landing page, hosted site, or your main storefront) and receive a welcome email automatically.
Manage and broadcast
The Newsletter page has three tabs:
| Tab | What it does |
|---|---|
| Subscribers | See everyone, by source and status; search; export to CSV; unsubscribe or delete (GDPR) |
| Compose | Write a subject and message, choose your audience (all, or a specific source/site), and send |
| Campaigns | Review past broadcasts with delivered/opened counts and a per-recipient breakdown |
Every broadcast includes a one-click unsubscribe link and an invisible open-tracking pixel, so your Campaigns tab shows how many recipients opened each send. Broadcasts use your SMTP credentials, the same as form emails.
Store-sourced subscribers and submissions carry their own Store badge and filter option in both the Subscribers/Submissions lists and the Compose audience picker — filter down to just your storefront's captures the same way you'd filter to a specific hosted site or landing page.
