Can re-engagment campaigns further harm your sender reputation

[KAaltonen]

Hi

We are planning to run a pilot re-engagement campaign to send a re-engagement email to about 460 contacts that are approaching unengaged status.

The question I have, if we can assume that most of these contacts are either graymail contacts or soon to become unengaged contacts and due to that we can also assume that the email performance will not be good, is there a danger that by running the re-engagement campaign we can harm our sender reputation? Any thoughts?

That volume will not hurt your reputation.  If you are worried about whether the data is still good you could try to cleanse or update the data with outside sources before you send to that list, but that's about as far as I would go with a list that size.
