was delivered email vs. was sent email

[FeliciaTan]

Hi,

What's the difference between the smart list filter Was Delivered Email and Was Sent Email. I assume the sent filter captures emails sent out but the delivered filter captures # of emails audiences actually received. Are there any use cases for two filters? Which filter is more practical (capture the number accurately) when the deliverability rate is really high?

Thanks,

Felicia

Sent means an attempt was made to send — which might’ve ended in a immediate soft bounce, immediate hard bounce, delivery, or out-of-band bounce.

Delivered means the email was initially accepted by the recipient’s mailserver. It doesn’t exactly mean “received” though. The mailserver could delete or quarantine the email after accepting it. Marketo doesn’t know about that final outcome.
