Mailchimp support

[vpetersson]

First, thank you for writing this. I was about to write my own, but this saved me the effort :)

One thing that I wanted to do was to integrate with Mailchimp (and possibly also Tracking Pixels). Would you accept a PR that adds Mailchimp support?

P.S. I did a little write-up here where I also mention this tool.

Hey @vpetersson

Sorry I thought I replied to this weeks ago but was on a train and it clearly didn't submit :)

Yes I would absolutely accept a PR for this feature.

Looks good to me so far! I've not used mailchimp myself but I'll setup an account to test before merging.

Note that this is untested! I will try to deploy it in the coming weeks.
