The trial clock is short and email is slow
A SaaS trial gives you a fixed window, often fourteen days, in which a stranger decides whether your product is worth paying for. Most teams work that window entirely through email. In markets where business buyers treat email as an archive and WhatsApp as a conversation, that choice costs conversions before anyone has said anything wrong about the product.
The second problem is measurement. Signups get counted as pipeline, so a forecast fills with accounts that logged in once, never activated, and were never going to buy. Activation, not signup, is the moment worth tracking.
