Do you agonize over how to close your emails? Email sign-offs can be tricky — they’re less formal than a written letter (does anyone send those anymore?) and more formal than a text. With no inflection, it can be challenging to convey the right tone in your closing salutations. Most of us have settled on a couple of signature wrap-ups for business and friends but it pays to review them on a regular basis so they don’t get stale. Case in point: ‘Regards’ used to be the go-to semi-formal closing but these days it’s beyond over.
