Hello @mmatei. So this was working fine previously and just stopped last month? That sounds like an issue with your mailer. However, I personally use the Discord notifications, not the emailer, so maybe a WordPress update happened that caused this that I didn’t notice. I’ll take a look at it today and let you know my findings. If there is something I need to fix on my end, I’ll patch it and push the update. The emails should be separated by commas like you have them.

Thank you @aristocles. Looking forward to get your observations. Have a nice week ahead!
Hi again @mmatei. Unfortunately, it won’t be as easy as having me fix something. I tested the emailing function with multiple email addresses using commas with and without spaces and it worked successfully for me on two of my sites using different emailers. The plugin isn’t the problem.
The “No Such User Here” error is a Post SMTP error (specifically a 550 SMTP error) that means the recipient’s email address does not exist or the recipient’s mail server rejected the email. I would check that the email addresses you are sending to aren’t blocking your website’s email address. If that’s not the case, make sure you’re using a 3rd party emailer like Brevo that helps prevent this, coupled with Dmarc, Dkim and SPF records on your domain’s DNS. Also, the admin email domain should match your site’s domain. I personally use WP Mail SMTP with Brevo on all of my sites but one, and it works great.
Hopefully you can figure it out. Sorry I can’t be more help.

Thank you so much. Your answer already gives a lot of useful information. Thank you for taking the time to look into it. I appreciate it.
I know that the DMARC and other server email settings, as well as the sending domain, are correct and matching the site domain. I’ll investigate the rest. I suspect that the receiving server may block it or something similar. I’ll talk to the receiving party to ask if that’s the case.
Much appreciated Ari 🙏
