Alert Channels

When a wp_mail() send fails — bad credentials, provider outage, blocked recipient — SendGrail dispatches a failure alert describing what broke. Email is the default delivery channel; these pages cover the chat-based delivery channels that complement (or replace) email alerts.

All enabled channels receive every alert

There's no per-rule routing for failure alerts. Whatever you toggle on (Email + Slack + Discord + Telegram) all get the same payload for every failure event. Use them as parallel notification paths, not as filters.

Email channel

The email channel uses WordPress's native mail function (with SendGrail hooks temporarily detached) so an outage on your SMTP provider can't suppress the alert. Configure it under Settings → Notifications. See Failure Alerts for the full feature breakdown and loop-prevention rules.
