MailCraft is a signal-led cold email studio that turns prospect research into sharp, personalized outreach in 8 seconds. Unlike generic AI email tools, MailCraft starts with the reason to reach out — a funding round, hiring push, product launch, or LinkedIn signal — and builds the email around it. Features: 6 tone profiles, 4-email follow-up sequence builder, editable drafts, email history, and one-click copy. Free tier included.
