TLS-RPT
Reports about TLS delivery failures between mail servers.
SMTP TLS Reporting lets domains receive aggregate reports when senders fail to deliver mail over TLS. It is commonly paired with MTA-STS so domain owners can see whether strict transport policies are causing 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 tls-rpt, 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.
