Yes. Import is subject to the same restrictions and anti-abuse policies as our main newsletter import. The difference is that importing new subscribers into an autoresponder will start the autoresponder mailing sequence automatically, using the import time as the start time. Like newsletter imports, you cannot use this import to overwrite a subscriber’s preferences, nor can you use import to “reset” where a subscriber is in the autoresponder sequence.
Import for autoresponders is at Responders | Import.
