Emails not sending from WordPress

Hi There,

This is driving me crazy and I’d really appreciate some learned feedback : – )

From time to time, I make minor updates to a WordPress website. Today the site owner texted me in a panic, saying that whenever anybody tried to send her an email via one of the “contact us” links on the website, it bounced back as “Undeliverable”. Tried it myself, and sure enough, that’s what happened.

She called the hosting provider and was told that the issue was caused by something I’d done in WordPress, and not an error on their end.

So my question is, how and where did I screw up?

When I hovered over the “contact us” link, I’m fairly certain it said “mailto:[email protected]”, and when I clicked on it, it opened a blank Outlook window with “info@domainname” clearly showing in the recipient field.

Could I have inadvertently changed a key piece of code? Will an email get sent if the “mailto:” syntax has an error in it? Is this even where the issue likely originated?

In hindsight, I wish I’d had the wherewithal to manually type in the email address and try sending it that way, rather than clicking on the WP link. But I didn’t, and the issue has since been fixed by the hosting party.

Thanks in advance for your help!
