prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  c7n-mailer - azure sendgrid pinned version not compatible with requirements.txt
  The requirements.txt is installing sendgrid==6.1.0, but we are pinned to sendgrid==6.0.5.
  
  We should look if it's possible to remove the pin in our setup.py
  
  ## Error:
  `c7n-mailer 0.5.4 has requirement sendgrid==6.0.5, but you'll have sendgrid 6.1.0 which is incompatible.`
