Mass Deletion of all Emails

[Leo Flores]

Hi Team,

We're currently working on deleting emails from our organization dated before 2022.

I have a command that pulls from a CSV containing the list of users whose emails need to be deleted—approximately 3000 users in total. I’m currently testing with a `maxtodelete` value of 1,000, but I’d like to increase it to around 10,000. Before doing so, I wanted to check if there are any known limitations or potential issues with setting it that high.

Also, would it be beneficial to add a multiprocessing flag or approach to improve performance and ensure the process runs smoothly?

Here’s the command I’m testing:


gam csv ./emailtest1.csv gam user ~primaryEmail delete messages query "before:2022-01-01" maxtodelete 1000 doit


Thanks!

This might be easier and a lot faster  to do with a Vault retention rule that would purge the emails prior to a specific date (or ongoing, once they get to be > 4 years old., maybe?)

See

Asking Gemini or Perplexity for “How do I use Google vault retention rules to delete all emails prior to 2022?” appears to give a pretty good set of step-by-step instructions, but I haven’t verified that they’re fully correct, so I’m not including them here. This is DEFINITELY a time you want to triple-check everything. 

Hope that helps,

Ian
