Manychat is rolling out Meta's longer Click to WhatsApp entry window, so businesses now have 7 days instead of 24 hours to answer the first message from a Click to WhatsApp ad. Once they reply, a 7 day free window opens, up from 3 days, in which marketing, utility and service messages cost nothing, and service messages sent in that window do not count against the 1,000 free monthly service conversations.
Teams running WhatsApp ads get more time to follow up at no message cost, which changes the economics of ad driven conversations.
