If you can't wait and want to get Playable working with an email platform not on the list, here's how:
1. On the Playable Embed page choose "Other"
2. Enter the Merge Tag for your email platform. This is a token like {{user.id}} or similar that will be replaced by a unique ID for each recipient.

[UPDATED 9/30] Customers tell us these Other integrations are possible, using the Merge Tags below:

* Amazon SES - {{meta.userId}}
* ConvertKit - {{ subscriber.email_address }}
* GrooveMail - {email}
* Lemlist - {{email}}
* Mailgun - %recipient_email%
* Wishpond - {{email}}
* Zoho - $[EMAIL]$
