Why Your WordPress Emails Aren’t Sending (And the Hidden Cost)
TL;DR
Your WordPress contact forms, order confirmations, and password resets are disappearing into spam folders—or never arriving at all. The problem? Broken SPF, DKIM, and DMARC authentication records that flag your emails as untrustworthy.
OnSiteWP fixes email deliverability problems permanently. We audit, configure, and verify your entire email setup so your messages land in inboxes, not spam folders.
You’ve sent the email. Your WordPress site says it was delivered. But your customer never got it.
Maybe it’s a contact form submission from a qualified lead. An order confirmation for a $500 purchase. A password reset for a locked-out user.
The email just… vanished.
Or worse: it landed in spam, where 99% of recipients will never see it.
You check your inbox. Nothing bounced back. No error message. So what happened?
Here’s the truth most WordPress site owners don’t realize:
When your website sends an email, the receiving mail server (Gmail, Outlook, Yahoo) runs a series of authentication checks before it decides whether to deliver it.
If your domain fails those checks—even slightly—your email gets flagged as suspicious, untrustworthy, or outright spam.
And most WordPress sites fail these checks by default.
Every Missing Email Costs You Money
Let’s do the math:
- A lost lead from a contact form? That’s a potential customer who thinks you ignored them. They’ve already moved on to your competitor.
- A missing order confirmation? Your customer panics, disputes the charge, and leaves a 1-star review saying your site is “sketchy.”
- A password reset that never arrives? Your user gives up, frustrated, and never comes back.
One broken email can cost you hundreds—or thousands—in lost revenue and trust.
And it’s not just about money. It’s about your reputation.
How do you know if you have a problem?
You might have broken email authentication if:
✅ Contact form submissions go straight to spam (or disappear entirely)
✅ Customers say “I never got my order confirmation”
✅ Password reset emails don’t arrive
✅ Gmail shows “via some-other-server.com” next to your domain name
✅ You get bounce-back errors mentioning “SPF fail” or “unauthorized sender”
✅ Your domain gets spoofed by scammers because you don’t have DMARC protection
Sound familiar?
Here’s why it keeps happening—and why “quick fixes” don’t work.
Why DIY Email Authentication Usually Fails
Email deliverability isn’t a WordPress plugin problem. It’s a DNS configuration and email authentication problem.
And the technical requirements are unforgiving:
- SPF records must list every legitimate sender (your web host, SMTP service, CRM, newsletter tool). Miss one? Your emails get rejected.
- Multiple SPF records conflict with each other and break everything.
- DKIM signing might be published in DNS but not actually enabled on the sending server.
- DMARC policies can accidentally block your own legitimate mail if configured with the wrong qualifiers (
-allvs~all). - WordPress itself often uses unreliable PHP
mail()instead of authenticated SMTP.
In other words: one wrong setting, and your entire email system collapses.
Even worse? You won’t know it’s broken until customers start complaining.
