I am happy to report that we have found and managed to correct the issue.

It seems that when we moved the database from the old domain to the new one, the email addresses (a few different ones) never updated to the new domain.
Even though I only started using SendinBlue AFTER moving to the new domain and AFTER the admin email was updated to the new domain.  The SendinBlue plugin does not override the database to the email address set up via the plugin. 

To resolve the issue we have downloaded a backup from the website, from which we extracted the database file and then manually edited the core setup emails including the one referring to relaying via SendinBlue.
We did not edit any emails relating to old orders/emails already sent.
We transferred the file back and restored it to the website.
For downloading and restoring we used Updraftplus via the wp-admin dashboard.

I have sent emails to check and even created a dummy order and the sender now seems to be correct.

I was scared that changing (even something simple as an email address) would break the site, but thankfully the edits we did doesn’t seem to have affected the rest of the website.

@santanainniss I have this nagging feeling its caused by something in the code of the site and I have no idea where to start searching. nevermind how to access the code when hosting with cloudways.

that Wrong old email address used to be the admin email of my website when I was using the old domain. I then migrated the website to the new domain, and just updated the admin emain in settings->general, as well as in my woocommerce. Later I moved to cloudways and then only started using sendinblue. I am going to dig into my admin emailbox and see if I can see if it was ever using the correct from email, since moving domains.

I guess this is not the hugest problem to have, but I would really like to stop using the old domain completely, but scared I then wont get my emails….

Currently the old domain is redirecting to the new domain, (setup my my domain host)

@santanainniss thank you for your reply. I have worked through all my SendinBlue settings with their support team, both those on their site as well as the plugin on my site and all those are set up correctly. SendinBlue support are conviced its a wordpress setting overriding the “from” email address.

I only started using SendinBlue after I had moved to the new domain. On the old domain and when I started on the new domain, I was using mailchimp.

@jdembowski my apologies and thank you, I wasn’t sure where to post it.

Thank you for fixing this, I am using the plug-in again and it works fine now. Sorry for the delayed reply but I got busy and forgot to come answer.
