If you received an email from WeTransfer saying your transfer couldn't be sent, one of the following is the likely cause.
Misspelled or invalid email address
Check the recipient's address carefully — look for typos, missing characters, extra spaces at the start or end, and confirm the domain is correct (e.g. .com vs .co).
Recipient's email couldn't accept our message
Their inbox may be full, they may have previously unsubscribed or blocked WeTransfer emails, or their address may be on a bounce list. Ask your recipient to check at wetransfer.com/fix-emails to re-enable delivery.
If the recipient isn't sure why they're not receiving our emails, please have them contact our Support Team with their address and we'll investigate.
Alternatively you can create a link transfer to then email personally a link to the files.
