We'd like to move off Mailchimp and send our newsletter via Zeffy. The one thing I haven't found is the ability to add things such as "membership expiry date" to the email as a variable field. We use this frequently as a reminder to those not on auto-renew that their membership has recently expired (or is expiring soon). It's just another place we can try to get them to renew and has been effective. Would love to see this added to Zeffy in addition to the current "firstname" and "lastname" variable fields. There may be a need for other fields as well, but this one is key for us at the moment. Thanks!
