How To Fix FluentCRM Not Sending Email [The BEST Way]

Is FluentCRM not sending emails from your website?

In this article, we’ll show you how to easily solve email deliverability issues with FluentCRM so that your emails don’t get lost or filed as spam.

What Is FluentCRM?

FluentCRM is a self-hosted email marketing plugin. You can design email campaigns in WordPress using the drag and drop block editor.

FluentCRM supports smart tags that let you dynamically personalize the content of the emails you send out.


It also supports:

  • Subscriber segmentation
  • Automated drip campaigns
  • Reporting
  • Integration with LMS and membership plugins.

If your emails aren’t being delivered reliably, let’s fix that.

How To Fix FluentCRM Not Sending Email

Ready to fix FluentCRM not sending email? Follow these steps:

  1. Check FluentCRM Email Settings
  2. Install the WP Mail SMTP Plugin
  3. Connect to a Mailer Service
  4. Enable Email Logging
  5. Resend Failed FluentCRM Emails Using WP Mail SMTP

Let’s first check if we have the correct email settings.

1. Check Email Settings In FluentCRM

FluentCRM lets you set the email sender within the plugin.

To check this, go to FluentCRM » Settings from your WordPress dashboard.

FluentCRM Settings

Click the Email Settings tab and you’ll find the fields to set the sender options.

Click on the Email tab

In the From Name, enter the name of your website or a name that your subscribers are likely to recognize.

For the From Email Address field, we recommend using an email with the same domain extension as the domain you’re sending from. This can sometimes help with email deliverability.

Click on Save Settings for the changes to take effect.

Let’s now install the WP Mail SMTP plugin to send all emails through a reliable email provider.

2. Install the WP Mail SMTP Plugin

FluentCRM uses the default wp_mail() function to send marketing emails from your website. It’s much better to use an email provider that can authenticate your emails instead.

WP Mail SMTP lets you easily connect your website to a mailer service and route all emails through it.

To download the plugin, head over to your WP Mail SMTP account. Under the Downloads tab, click the orange button to grab the latest version of the plugin file.

Download the WP Mail SMTP plugin

Switch back to your website and upload the zip file to the plugins page.

Once the plugin is installed, be sure to Activate it. As soon as you do that, the plugin Setup Wizard will start in your browser. The wizard will help you to configure the plugin in few easy steps.

3. Connect to a Mailer Service

In this step, we’ll connect the website to a mailer service that’ll add authentication to your marketing emails.

To begin, click the Let’s Get Started button in the wizard.

On this screen, you can choose your new email provider. We recommend that you use an email provider with an API, like Sendinblue or SMTP.com.

Switch back to this website once you establish a connection between the mailer and your website.

4. Enable Email Logging

As you come to the end of the Setup Wizard, you’ll have the option of turning on email logging.

We recommend that you turn on the Detailed Email Log and Weekly Email Summary.

This will log the basic details about your emails and send you a weekly report. You can check out all other email logging features in detail in our article on how to log your WordPress emails.

WP Mail SMTP will check your DNS settings and sends a test email. If everything is correctly set up, you’ll see a success message in the end. If there’s an issue with the DNS settings, it will show you details of the error.

Let’s now see how we can resend failed marketing emails using WP Mail SMTP.

5. Resend Failed FluentCRM Emails Using WP Mail SMTP

Even after setting up the mailer service on your website, some emails may fail to deliver. This can happen if your SMTP server or email provider has a brief outage.

To combat this, we recommend that you log the entire contents of your emails.

You’ll find this setting in WP Mail SMTP » Settings.
