Your email is never late
Ploum in Do not apologize for replying late to my email:
As soon as my email was sent, I probably forgot about it. I may have thought a lot before writing it. I may have drafted it multiple times. Or not. But as soon as it was in my outbox, it was also out of my mind.
I am wholeheartedly behind Ploum on this. Never apologise for replying late to my email.
