You can send up to 500 invites per day. We try to strike a balance between providing artists with enough invites to give everyone on their press list an early listen, and not opening up the possibility that a less upstanding individual could use the service for spamming (thereby ruining the party for all). If you’re looking to send to a larger list, you might consider download codes instead, which also work with private tracks and albums and have no such restrictions (since you, not Bandcamp, mail them out).
Bandcamp Support is experiencing an unusually high volume of emails from our wonderfully successful fundraisers this summer, so our responses may take an extra few days. We put together a list of common questions to help you help yourself in the meantime - power!
