Errors when sending emails

Hi @tcdssupport ,

Thanks for reaching out.

Based on the error message, it seems that right now your site is using the ‘Default’ (PHP) mailer option in the WP Mail SMTP plugin. This is the method your site uses to send emails when SMTP is not set up.

Generally speaking, it is not recommended to use the ‘Default’ (PHP) mailer because your emails will not be authenticated and your email deliverability may be low enough that your emails will end up in spam folders or might not get delivered at all.

In order to configure your site to send emails authenticated for better deliverability, you’ll need to set up one of the SMTP Mailer options in the plugin (here’s a screenshot of the options) and configure its settings.

Setting up a WP Mail SMTP Mailer

Here’s a tutorial for setting up each of the available mailers.

Recommended Mailers

If you’re not sure which mailer to go with, we recommend transactional mailers first. Transactional email service providers such as our #1 recommended mailer, SendLayer, are probably best for sending emails, as far as reliability goes. Brevo (formerly Sendinblue), SMTP.com, SendGrid, Mailgun, etc., are also transactional email service providers if you’d like to consider your options.

These would also allow you to send emails with a custom ‘From Email’ specific to your domain (examples: [email protected], [email protected]).

I hope this helps. Thanks 🙂
