Update Email Domains

[Anonymous]

I do not have SFDC.  An entire school district just changed their email domain. Is there a way to update these in bulk, or do I hca to go into each of of the 200 contacts and change the domain manually?

You will likely need to do this manually.

If you export to Excel and then reimport, Marketo will view the record as a new lead and then you'll have to merge them later.

It may be possible to do this in SFDC instead with people import. Pretty sure Marketo would view this as a Changed Data Value instead.
