Thank you for your answer....let me try to explain better.
The function I'd like to set is: when a customer subscribe to our Hika shop, autorespond a confirmation showing a specific delivery day based on the geo area of the customer ( not the country but the city, our is a local business, could be managed by matching a list of postal codes ). So I though it could be setted inserting customer subscribed in specific list dedicated to a geo area and then creating an automatic campaign.
Can I manage this with Acymailing?
