Once transaction is confirmed and sent to blockchain, you will receive an email «Your Request has been processed». It takes approximately 1 hour to arrive at the recipient’s address.
You can always track the transaction processing via blockchain using its unique TXID or your transaction ID. TXIDs can be also mentioned as transaction hashes and can be found in History details. Transactions can be tracked in different publicly available sources such as https://www.blockchain.com/explorer for bitcoin transactions.
The recipient of your cryptocurrency transfer may also request this transaction ID from you. This transaction ID is safe to share.
