SEPA Direct Debit Rejected IBAN Mismatch Email Template

Use this page when a SEPA direct debit failed because the IBAN or debtor account details used for collection do not match the buyer's authorized setup. This is more specific than a generic bank rejection. The issue is that the mandate may exist in principle, but the account data tied to it appears wrong or outdated, which prevents the debit from being honored. Your email should ask which IBAN should be used, whether the buyer changed bank details without updating the mandate record, whether the rejection came from the debtor bank or buyer-side setup, and when the corrected account can be used for collection. The result you want is a clean path from rejected debit to corrected re-presentation. It is commercially strong because the visitor is dealing with a failed automatic collection on a live receivable and needs precise wording that fixes the account mismatch fast.
