Send a personalized welcome email from the hiring manager within 24 hours of offer acceptance.
ContextThe period between offer acceptance and the start date is when competitive counter-offers and second-guessing are most common. SHRM estimates approximately 17% of new hires leave within the first 90 days, and a meaningful subset never reach Day 1 — primarily because the pre-boarding period feels transactional or silent. The welcome email should come from the hiring manager (not HR alone) and answer practical questions: exact arrival time and location, who to ask for at reception or the link to the Day 1 video call, dress code if not obvious, and what the first few hours will look like. The tone carries as much weight as the logistics — a warm note that says 'The team is genuinely looking forward to having you' reduces the anxiety that fuels second-guessing. If the start date is more than two weeks out, schedule a light mid-point check-in: a brief message asking if they have everything they need before Day 1 maintains the relationship without overwhelming them.
