Contact Form Emails Going to Spam
Fix Deliverability (And Stop Missing Leads)
If your contact form emails keep landing in spam, your form might be “working” — but your delivery setup isn’t. This usually happens because of sender authentication issues (SPF/DKIM/DMARC), spoofing behaviour, or poor server reputation. Web2Phone helps by delivering enquiries to WhatsApp (harder to miss) and email — with a dashboard record.
Works with HTML forms, static sites, Webflow, WordPress (custom forms), and more.
Spam Filtering Is Doing Its Job (Even When It Hurts You)
Providers assume form emails are suspicious because they often look like spoofing: your website server sends a message that claims to be “from” a random visitor’s email address. That’s exactly the pattern spam filters are trained to block.
- Submissions land in spam/promotions or get quarantined.
- You only find out after a customer complains.
- The form shows “success”, so you assume everything is fine.
- You lose leads quietly — the worst outcome.
Fixing deliverability matters, but you should also add a delivery channel you’ll actually notice (like WhatsApp) and keep a dashboard record so enquiries can’t vanish.
- Delivery to WhatsApp (safer “don’t miss it” channel)
- Email delivery too (searchable record)
- Dashboard record even when delivery fails
- Domain allow-listing + rate limiting
- Works with your existing HTML form
Why Contact Form Emails Go to Spam
Most spam problems come down to authentication and trust. If providers can’t verify that your server is allowed to send email for your domain — or your messages look like spoofing — they’ll filter them.
SPF/DKIM/DMARC issues
DNS authentication records don’t match your sending server, so providers treat messages as untrusted.
“From” spoofing behaviour
Many forms set the email sender to the visitor’s email. That often triggers spoofing rules and filtering.
Server/domain reputation
Shared hosting IPs can have poor reputation. Even legitimate messages get filtered because “neighbors” abused the IP.
You can improve deliverability — but it’s still smart to deliver enquiries to WhatsApp as well, and keep a dashboard record no matter what.
Set up WhatsApp + Email delivery →Improve Reliability in 3 Steps
Keep your existing form. Web2Phone receives the submission on our backend, attempts delivery to your chosen 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.
<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>

If your form emails are going to spam, these are the changes that usually move the needle.
1) Stop spoofing the “From” address
Don’t set the sender to the visitor’s email. Use a domain-based sender (e.g. no-reply@yourdomain)
and put the visitor’s email in Reply-To.
2) Fix SPF/DKIM/DMARC alignment
Ensure your DNS records authorize your sending service and align with the domain used in the sender address.
3) Avoid shared hosting deliverability issues
Shared IP reputation can hurt deliverability. If possible, use a reputable sending service with authenticated domains.
4) Create a safer delivery path
Even with perfect DNS, email isn’t guaranteed. Deliver enquiries to WhatsApp as well and keep a dashboard record.
Stop Letting Spam Filters Hide Your Leads
Web2Phone receives submissions on our backend, attempts delivery to your chosen channels, and stores a dashboard record so enquiries don’t vanish. Use WhatsApp as the safer “don’t miss it” channel, with email as the searchable record.
