Customer.io

If you have a very small database of people, then probably the whole integration isn't justified. If you have a small business and don't plan to scale much, don't do it. It will be expensive for what you can get elsewhere (Mailchimp).If you want a scalable and powerful platform, that will take some time to pay off, and you can wait, then do it. Once you get integrated and start sending events and attributes, the things you can do are almost limitless.

Cons

Customer.io

  • I may be missing it in the UI, but a place to see the list of emails who qualify for a certain email.
  • One easy to view chart of all our automated/lifecycle emails to see what a given user would see over their customer journey. (This is really just a feature request/idea - the product itself is really awesome.)

  • Maybe User Interface should be lifted up a bit but for Professional use that doesn't matter a lot

Alternatives Considered

Customer.io

Customer.io was really the first pure, full-featured drip email program on the market and as far as I know, it's still the simplest and best overall for that specific function. SendGrid has also added drip campaign features, but I would seriously evaluate Customer.io against any other drip email provider because they really have all the key elements you need to make it work.
