Hostinger Email + Let’s Extract Studio Sending Error Despite Successful Test Email

I recently purchased hosting from Hostinger and my website is in the process of going live. I’m also using Hostinger’s email service to run a cold email outreach campaign combined with the latest version of Let’s Extract Email Studio.


I was able to set up the SMTP successfully ,the test email goes through without any issue. However, when I try to send an email campaign to a list especially with attachments or multiple contacts added manually, I keep getting a sending error, and I’m not sure what’s causing it.


The manual only covers basic setup, but there’s no troubleshooting guide if something goes wrong and I’m not very familiar with the technical side of the tool.


If anyone has faced this or can guide me step-by-step, I’d really appreciate your help!


Thanks in advance
