What are the best tools to manage event-triggered email campaigns?
Can anyone recommend any email marketing tools that help you set up and manage trigger emails effectively?
Have a look at both http://www.activecampaign.com/ and https://convertkit.com/ and see if they will do the job for you. Both are reasonably priced, and both have sophisticated rules, or triggers, which allow you to segment your lists depending on certain events, like whether the reader opens a link, or downloads a file, etc.
Infusionsoft is another - we use it successfully, still; be aware it is known as 'confusionsoft' by the majority of users
