Missing Contact Form Submissions
Fix Lost Leads (And Stop It Happening Again)
If you suspect enquiries are going missing, you’re probably right. Email delivery and form plugins fail silently more often than people admit. Web2Phone reduces the risk by delivering submissions to WhatsApp (harder to miss) and email — plus a dashboard record.
Works with HTML forms, static sites, Webflow, WordPress (custom forms), and more.

Do these checks first — they catch most “missing” leads:
This Is the Worst Kind of Failure: Silent
Missing submissions aren’t just annoying — they directly cost you business. The common pattern looks like this:
- You see a drop in enquiries, but traffic is steady.
- Someone says “I filled your form in last week” — and you never saw it.
- The form shows a success message, but nothing arrives in your inbox.
- You waste hours testing… and it “works” when you test it.
The brutal truth: email-only delivery is not guaranteed, and many form setups have weak points that fail quietly. You need an approach that improves delivery and keeps a record of every submission.
✓ What Web2Phone Changes
- Delivery to WhatsApp (safer “don’t miss it” channel)
- Email delivery too (searchable record)
- Dashboard record so submissions don’t vanish
- Domain allow-listing + rate limiting
- Works with your existing HTML form

The Most Common Causes of Missing Submissions
Most “missing submissions” aren’t one big bug — they’re a chain of small failure points. Here are the ones that show up over and over.
Spam filtering / quarantine
Messages land in spam, promotions, or quarantine. Nobody checks there, so leads look “missing”.
Hosting restrictions
Some hosts block outbound mail, restrict SMTP ports, or disable mail(). The form still shows “success”.
SPF/DKIM/DMARC issues
If DNS authentication doesn’t match the sender domain, providers reject or quarantine emails.
Bad “From” behaviour
Using the visitor’s email as the sender triggers spoofing rules. Delivery becomes unreliable.
Plugin/theme conflicts
WordPress form plugins and themes can break after updates or interfere with submission handlers.
Forwarding + inbox rules
Forwarders fail silently, shared inboxes auto-archive messages, and rules misfile submissions.
Stop Losing Submissions in 3 Steps
You keep your existing form. Web2Phone receives the submission on our backend, attempts delivery to your selected channels, and stores a record in your dashboard.
Create an Endpoint
Sign up, create an endpoint, choose delivery (email, WhatsApp, or both), and add allowed domains.
Add the Embed Script
Add attributes to your form and include the Web2Phone embed script on the page.
Receive + Log
Web2Phone attempts delivery and stores every submission in your dashboard.
Example: Reliable Form Submission Delivery (HTML)
<form data-web2phone="form"
data-public-key="YOUR_PUBLIC_KEY"
data-endpoint="https://web2phone.co.uk/api/v1/submit/">
<input type="text" name="name" placeholder="Your name" required>
<input type="email" name="email" placeholder="Your email" required>
<textarea name="message" placeholder="How can we help?" required></textarea>
<button type="submit">Send message</button>
<p data-w2p-output></p>
</form>
<script src="https://web2phone.co.uk/static/formsapp/js/embed.js"></script>Tip: Enable domain allow-listing to prevent unauthorized sites from submitting to your endpoint.
Quick Checks If You Suspect Missing Submissions
If you’re investigating missing contact form submissions, these checks usually reveal the cause quickly.
Check spam/quarantine + inbox rules
Don’t just check “Spam”. Check promotions, quarantine, and any rules that auto-archive or auto-label form emails.
Check DNS authentication
SPF/DKIM/DMARC issues are a major reason emails disappear. Misalignment causes rejection or quarantine.
Check hosting restrictions
Some hosts block outbound mail or require verified senders. The form can “succeed” even when delivery fails.
Confirm the form isn’t being hijacked
Plugins, themes, and scripts can intercept form submits. Test with a plain HTML form to isolate behaviour.
Stop relying on email-only delivery
Use WhatsApp as the “don’t miss it” channel and keep a dashboard record so submissions can’t vanish silently.
Use a dashboard record as truth
Delivery channels can fail. A stored submission record means you can always see what was sent.
