It can be very frustrating experience figuring out all the options of various autoresponder services. If you don’t choose the correct one you may regret it later. First think about about why you need one, then look at the pros and cons of each type. For example if you only need to send an automated reply to emails you receive a single response autoresponder would be sufficient. If you need to send a series of follow-up email messages then a sequential autoresponder is necessary.
