Scrubbing email lists

[Anonymous]

Hello

I would like to know if any one has any good processes set up around maintaining the integrity of an email list. How do you usually approach bounced emails and how do you go about trying to clean them up? I know that some bounces are due to invalid emails while others are due to a variety of 500 or 400 email error codes.

If anyone has any good suggestions I'm all ears!

Thanks in advance

I would consider setting up some suppression lists for the bounces.  Are you noticing any increase in the hard or soft bounces you are seeing?  This previous thread in the community has some good information about suppression lists and cleansing your data.
