Hi! I updated to rails 5 and it worked like a charm. I think this was the push I needed to make the update. Still, if this can be helpful, in rails 4.2 it raises two errors:

return true if elm&.dig(:email) == additonal_mail
I think I solved it by changing it for elm[:email] == additional_mail

With that I was able to send a mail with the simple fields (:to, :subject) and I think with :categories as well. The error was raised when I added the OptionalField :personalizations. I think uparsed_valuechanged its behavior in rails 5. So then gem could be usable in rails 4 with the above change, but not with personalizations at least.

Thanks for the reply!

Hi @somiryu, can you confirm you are on the current version of the gem. Also, if you could share a full stack trace that would be helpful. Specifically, which Mail::OptionalField is throwing this error.

Hi I'm still getting this when trying it out in the console with "custom_args" (works if i remove custom_args)

	def sendgrid_test(to_email)
		mail(:to => to_email, :subject => "Test", custom_args: {campaign: 'welcome'}) do |format|
			format.text { render :plain => "Test message" }
		end
	end
