Client Registration Custom Email via mailgun api

[tommy.developer]

Hi Good day!
I have use the default registration form as shown in the image

but I want to customize the email being sent to the user/newly register.
I am using Mailgun API only.
and also want to send email notification for a customer whenever there are promos and updates. and eventually it might behaving a configuration for email content and etc.

therefore, what I need now is a fully customize email or mailer using mailgun.
some sort of questions as follows:

• How to do the configuration of email using Mailgun API aside from doing it in .env file?

• How to create a fully customize email upon registration?

• How to create a customize email for other stuff such as promos,update etc ?

• How to implement the customize email in Client ?

that's it for now.
thanks and more power Aimeos!

Aimeos uses the e-mail infrastructure of Laravel and the registration form including all related e-mails is provided by the Laravel authentication framework. Thus, refer to the Laravel documentation or a Laravel forum for answers to your questions.
