Troubleshooting Email Notifications

Are you experiencing problems with the delivery of your form’s notification emails? There are several factors that can affect email deliverability, but in most cases, adjusting notification settings or setting up an SMTP server is the solution.

This guide will walk you through troubleshooting notification emails in Nelio Forms.

Checking Email Notification Settings

If you’re experiencing email delivery issues, it’s best to first check your form’s notification settings. Here are some things to look for:

  • Typos: Check that all emails are spelled correctly.
  • Sender: In some email providers, having the same Send To Email Address and From Email Address can be flagged as spam or blocked from delivery.
  • From Email Address: There can only be one From Email. Also, in some cases using a domain-specific email address as the From Email Address can improve deliverability (ie

Installing and Setting Up an SMTP Plugin

WordPress sends emails generated by WordPress or any contact plugin, such as Nelio Forms, using the PHP mail function by default. The most typical cause of email failure is that your WordPress hosting server is not set to use the PHP mail() function.

Furthermore, email providers may flag or prohibit emails that arrive from a different domain than the one claimed. For example, if your From Email Address is but your domain is, an email provider may deny the email due to a domain mismatch.

We advocate utilizing SMTP to send emails in WordPress to overcome email delivery concerns. In contrast to the PHP mail function, SMTP improves email deliverability by utilizing proper authentication.

You can find several SMTP plugins in the WordPress Plugin Directory. Select the one that fits your needs and set it up.

That’s it! Hopefully, these steps have helped you to resolve email deliverability issues on your site.
