I would like to setup an auto-responder in Gmail that includes an attachment. I can setup the auto-responder without issue but how do I add an attachment to an auto-responder in Gmail?
I am not sure if this can be done via Gmail.
I can suggest writing a simple application that connects to your server, checks new emails, and sends new email.
I am sure there are plenty of similar free tools available online.
The Gmail automatic vacation response feature doesn't seem to allow attachments. However, you can include a link to the attachment in the response. You can upload the file to a Google Docs account, and share the file to anyone with the link. Or you could upload the file to some other file sharing service.
You can look at uploading your attachment to a file hosting site e.g. mediafire. The problem I have found with this however is that the autoresponder message limits you to how many words you can put in the message which for me turned out to be a challenge as my autoresponse requires a lot of instructions!
