Hi, Aidan.
In our forums we keep our threads focused on just one issue at a time to ensure we fully answer each of your questions/issues. Please keep this in mind for the future and start a new thread for your additional questions from this thread. Thanks for your understanding, and I’ll answer only your first question…
1)
If you’re using WooCommerce, please go to wp-admin > WooCommerce > Settings > Emails tab > and see if that email address is what’s set for your “From” address option
2)
Please create a new forum thread about this separate topic. Please include a link to an example event that is at least 2 weeks in the future.
