“Regards”. “best wishes”. “Warmly”. “Cheers”. “Take care”. The words at the end of a professional email may seem banal. Still, the sign-off matters. Even the ubiquitous “Sent from my iPhone” can act as a justification for brevity and typos or as a virtue-signal that the sender has taken the time to reply although clearly not at their desk. It is therefore worth considering how your missive’s ending will be perceived on the other end, not least because it is likely to be archived away in perpetuity.
