The main criteria you should look for while shopping for an autoresponder service are usability and effectiveness.

Is the interface is hard to manage or navigate? Is it easy to quickly compose a message and blast it to your list? Is it easy to check the stats and reports? These are the types of questions you’ll need to ask to ensure that the service scores high on the useability criteria.

Effectiveness is determined by how many messages are delivered to your recipients and how many get opened. Is the delivery consistent? Are open rates consistent? Other factors like your subject line and relationship with the prospect also impact your open rates. But, you still need to know that your autoresponder service is doing everything it can to make sure your messages are delivered and read.

There are several other criteria to consider as you can see in the comparison chart below.

In summary…

If you’re looking for a great autoresponder there are two clear choices. If you’re pretty new to the whole concept of automated email, we recommend MailChimp for its friendly interface, ease of use and great service and support.

If you’re more confident with your email marketing, AWeber has proven itself time and again as a user-friendly, comprehensive platform for all your requirements, with more options for customisation than MailChimp provides.

There is, however, another option if you’re looking to gain complete control over your email marketing strategy and develop a bespoke solution that enables you to truly define, own and manage all aspects of your strategy
