E-mail for Christmas – Experiences Some figures: ~ 1/3 of follow up households in Austria provided an e-mail address Plausibility check was made before sending out the e-mails ~ 15 addresses were corrected < 10% of those with e-mail address were undeliverable Some of the undeliverable cases could be corrected because there were obvious typing errors
