Email validation in Checkout
Fundraise Up validates email addresses that supporters enter in Checkout Modal or on a Campaign Page. This validation helps reduce bounced receipts and transactional emails.
Email validation purpose
Email validation helps protect deliverability for emails sent by Fundraise Up. Addresses that are expected to bounce can affect sending reputation and make it harder for supporters to receive receipts and other transaction-related messages.
This validation applies to emails sent by Fundraise Up. It does not directly determine deliverability for messages that your organization sends through other services.
Email validation process
Fundraise Up sends the supporter’s email address to ZeroBounce for real-time validation. If ZeroBounce rejects the address, the supporter must enter a different email address before completing the donation.
Resolve a rejected email address
If a supporter reports that Checkout rejected a working email address:
- Check the address for typos and formatting errors.
- If the address is correct, contact Fundraise Up Support and provide the rejected address and relevant details.
Fundraise Up Support can review the rejection and, in some cases, mark the specific address as valid. Domain-wide whitelisting is an exception because it can allow mistyped or nonexistent addresses to pass validation.
