Hi @ivanivanov18 and @nomad1108,
Thank you for reaching out to us and we apologize for the delay.
We were able to reproduce the issue, the notification should not appear if you’ve performed the necessary steps, but Sendinblue – WooCommerce Email Marketing/Newsletter, SMTP, Email marketing and Subscribe forms by Sendinblue had recently performed an update and now we need to verify that there is indeed no conflict.
To add a bit of context, if the “Enable Sendinblue to send WooCommerce emails.” option is enabled, it will conflict with WP Mail SMTP since you are already using the Sendinblue mailer.
In the meantime, since you are not experiencing any issues on in regards to email delivery, if you’re willing the notification can be removed with a little custom code:
// Exclude "Sendinblue - WooCommerce Email Marketing" plugin form WP Mail SMTP conflicts list.
add_filter( 'wp_mail_smtp_conflicts_is_conflicting_plugin', function ( $conflict, $plugin ) {
if (
isset( $plugin['slug'] ) &&
$plugin['slug'] === 'woocommerce-sendinblue-newsletter-subscription/woocommerce-sendinblue.php'
) {
$conflict = false;
}
return $conflict;
}, 10, 2 );
In case it helps, here’s a tutorial with the most common ways to add custom code like this: https://www.wpbeginner.com/beginners-guide/beginners-guide-to-pasting-snippets-from-the-web-into-wordpress/.
For the most beginner-friendly option in the guide above, I’d recommend using the WPCode plugin: https://www.wpbeginner.com/plugins/how-to-easily-add-custom-code-in-wordpress-without-breaking-your-site/. This will protect your code from updates and keep it easy to manage right within your WordPress admin area.
I hope this helps! Could you please let me know if I can clarify any of the information above or provide you with more details?
Thank you! ??
