GSuit limit for recipients

Dear community,

This weekend I tried to post (using patman) a patch set that should have been sent to 120 recipients (a lot of files were changed).

I've got an error from the Gmail SMTP server: 4.5.3 Your message has too many recipients. For more information regarding 4.5.3 Google's sending limits, please visit: 4.5.3 https://support.google.com/mail/?p=TooManyRecipientsError e1sm1539543ljp.114 - gsmtp

The doc says there is a limit for recipients - 100 per message. All my emails are hosted by Gmail/G-suit. I think I'm not the first who faced such an issue. Could you share your tricks or best practices on how to post patch sets with more than 100 recipients without changing an e-mail provider?

Thanks in advance for your help!
