Relay does not currently integrate with Zelle, but adding Zelle compatibility is something we're actively working toward! In the meantime, we recommend keeping an eye on your email notifications, as we'll share updates as soon as this functionality becomes available.
In case your business partners cannot be paid through ACH, wire, or check, we're happy to recommend PayPal or Melio as alternative vendors that we integrate with.
More information about the various platforms that Relay works with can be found here.
