I have hundreds of legacy subscriptions to my primary account already. Can Lockrmail migrate these to my Lockrmail address?
This would build the stickiness of all my newly subscribed newsletters coming through lockrmail to truly manage my newsletter/email flow.
May be very difficult, as you'd need permission to read my primary email, and some way to re-subscribe me via lockrmail.
For context, services like unroll.me are great at batch unsubscribing, but come at a data-sharing privacy cost.
