Overwhelmed inbox

Every morning, 20 to 50 emails from clients, partners, or business inquiries. All require personalized but similar responses.

Precious time wasted

2 hours per day writing the same types of responses: polite refusals, meeting confirmations, follow-ups... Time that could be spent on core business.

Missed opportunities

Too slow response = opportunities missed. Rushed response = unprofessional image. The modern professional's dilemma.
