Email sent showing HTML tags (not always)

Hi @seanseale11.

Actually, plugin is not touching email body. Also it shouldn’t change email type (e.g. text or html).

If you enable log, you can see email body and headers there. Try to see if there’s anything unusual in those. Try to send emails to other address (not yahoo.ca). Also, try to disable the plugin and send email without it to yahoo.ca and see if the problem is still there.

Are emails being sent by some contact form?

Alex,

There isn’t anything unusual in the code (when I copy/paste it to an HTML converter, it looks absolutely fine).

The HTML issue only happens sporadically, but yahoo.ca emails definitely have more errors than others overall.

The problem still persists even without the plugin (only sometimes though, like I mentioned before). It’s hard to “replicate” the error.

Yes, the email are being sent through Formidable Forms (form builder).

Does that give you any useful information as to what might be going on?

If emails are still broken without the plugin enabled, this means it’s not caused by the plugin. Some other plugin can cause this, also it can be caused by mail server (either by the one used by your site or by yahoo.ca).

That I suggest to do is following: keep debug log enabled. When you catch broken email, compare its body and headers with the one that was sent from the server. This way you’ll be able to see the difference and most probably would be able to see what’s causing it.

Which SMTP server are you using btw? Is it gmail or similar or is it you hosting company server?

Alex,

It’s a hosting company server.

I’m checking the code with https://validator.w3.org/#validate_by_input and already found some errors. I’m cleaning it up and will keep testing to see how it goes. You can consider this thread closed, for now, I’ll reach out again when I have more information.

Thanks for pointing me in the right direction!

No problem, Sean.

According to my past experience with similar issues, it was usually one of the mail servers that was adding additional things to the email (like some spam-score headers which were inadequately handled by some email clients etc).

Please do post your findings. There might still be a chance that there’s a conflict between Easy WP SMTP and some other plugin. If it is, you’re the only hope to find it ??
