How to send an email to new subscribers without using a third party

Hi,
I would like to know if there is a way to send an email to someone who just joined the mailing list? I am using mailgun as an email provider.

Thanks

Mailgun may be used for both transactional and bulk (newsletters) email. So what problem do you have?

Hi @mjw,

I set up mailgun for transactional and bulk emails, but the people joining the mailing list are not getting a custom welcome message. How can I set it up?

Thanks

Take a lock at this guide.

Is not possible to do it without a third party app?
