What is the quickest way to get an auto-email response for registrants?
I use Thunderbird and have user registering to be a part of my outbound email campaign. So, the subject is predicted, "REGISTER".
What is the easiest was for me to generate an auto-response to them?
Can I do this with Thunderbird? Is there an IMAP service that provides this?
ShouldI consider using Outlook?
