The SB WordPress plugin does have setting to enable Transactional via SB. This covers all outgoing emails from WP including Woocommerce email. (tested)
But
The SB for Woocommerce plugin ONLY have settings to enable transactional email for Woocommerce email only such as order statuses, notes. But i tested, it worked too for other wordpress emails such as from form plugin.
I think you should mention in the plugin description that it does replace wp_mail once enabled in the settings so that there will be no confusion & conflict between other smtp plugins.
And my suggestion:
1. in the Sendinblue Email Sending Options – put a remark that once enabled, this will replace wp_mail.
My other questions:
1. Will this create conflict with other smtp plugins when i enabled the sending via sendinblue option?
2. Any tutorial on use case of sending order price to sendinblue?
thanks
