Contact Form Not Sending Emails
Fix Missing Submissions (Without Guesswork)
If your contact form “works” but emails don’t arrive, you’re not alone. Email delivery is unreliable — and the worst part is it often fails with no obvious error. Web2Phone helps by delivering submissions to WhatsApp (safer for fast replies) and email — plus a dashboard record.
Works with HTML, static sites, Webflow, WordPress (custom forms), and more.

When Emails Fail, Leads Disappear
This is the nightmare scenario: a customer submits your form, sees a “success” message… and you never receive the email.
- Emails land in spam/promotions, or get filtered by your provider.
- Shared inboxes + forwarding rules fail silently.
- Hosting blocks
mail()or outbound SMTP without warning. - Misconfigured SPF/DKIM/DMARC causes rejection or quarantine.
- Plugins/themes intercept submissions (especially on WordPress).
If your business depends on enquiries, relying on email-only delivery is risky. You need a channel you’ll actually notice — and a record of every submission.

- Delivery to WhatsApp (safer for fast replies)
- Email delivery too (searchable inbox record)
- If delivery fails, the submission is still saved in your dashboard

Why Contact Form Emails Fail So Often
A contact form submission is not the same thing as “an email will definitely be delivered”. Forms depend on server-side mail systems, DNS authentication, provider spam filters, and forwarding rules — and any weak link can cause silent failure.
Shared hosting and SMTP are fragile
Many hosts restrict outbound mail, block ports, or disable mail features. Even when it “works”, deliverability can be poor.
Spam filtering is unpredictable
Providers score and filter messages constantly. A form email can be quarantined, delayed, or dropped without you noticing.
That’s why many teams deliver enquiries to WhatsApp as well as email. It’s harder to miss — and Web2Phone still keeps a dashboard record either way.
Set up WhatsApp + Email delivery →Fix It in 3 Steps
Keep your existing form. Web2Phone receives the submission on our backend, attempts delivery to your chosen channels, and saves a record in your dashboard.
Create an Endpoint
Sign up, create an endpoint, choose delivery (WhatsApp, email, or both), and add your 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 to your selected channels and stores the submission in your dashboard.
Example: Reliable Contact Form 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 so only your approved domains can submit to the endpoint.
Troubleshooting: Common Reasons Emails Don’t Arrive
If you’re debugging an email-only contact form, these are the usual culprits. (And yes — they often fail silently.)
1) Host blocks mail() or outbound SMTP
Some hosts restrict outbound email, require verified senders, or block ports. Your form “submits” but nothing delivers.
2) SPF/DKIM/DMARC misconfiguration
If DNS authentication doesn’t match the sender domain, providers may reject or quarantine messages.
3) “From” address causes rejection
Using a user-submitted email as the sender often triggers deliverability issues. Providers treat it as spoofing.
4) Spam filtering / inbox rules
Emails can land in spam/promotions or be auto-archived. Check filters, rules, and quarantine folders.
5) Plugin/theme conflicts
Some form plugins override handlers or break after updates. You see success on-page, but delivery never happens.
6) Rate limits or bot protection
Some setups reject repeat submissions or certain IP ranges. If you test rapidly, you may trigger blocks.
