It’s very annoying that when replying to an email through the HubSpot interface, it adds the prefix “Re:” to the subject line — not only to the first reply, but to every single reply you’d send via HubSpot. Leading to a very unreadable subject line :
"Re: Re: Re: Re: Re: Re: [The_actual_subject_line]
The reason this is annoying is that some email clients would just consider the sent message as a new thread and not show it within the initial thread.
It would be better if HS would ditch this (very old-school) practise to put “Re:” in front a subject line.
