Soft bounce
A temporary delivery failure.
A soft bounce means delivery failed for a temporary reason such as a full mailbox, greylisting, rate limiting, or a transient server issue. Providers usually retry soft bounces before converting them into final failures.

Growth work lives or dies on targeting and measurement. What matters is whether behavioral triggers can be built without engineering time, whether the event stream supports attribution past the open, and whether deliverability holds when broadcast volume shares a reputation with product email.
Applied to soft bounce, that means weighing scheduling, event stream, deliverability, and operating track record ahead of the rest, against behavior-triggered journeys, broadcasts, and winback campaigns measured on revenue.
