};Get notified when emails bounce or are deferred. Trigger on message.bounced and message.deferred webhook events and post diagnostic details to your ops channel.
is_bot = true when the event came from a security scanner, link prefetcher, or corporate email gateway (not a human). Common with Barracuda, Proofpoint, and Mimecast.
is_mpp = true when the event came from Apple Mail Privacy Protection, which pre-fetches all images and inflates open counts. Affects roughly 50% of iOS/macOS mail users.
Both fields are Booleans on engagement events (opened, clicked). Always guard with == true since they may be absent on non-engagement events.

};MailOdds goes beyond validation. Monitor your entire sending infrastructure from Slack.
Sender reputation, blacklist detection, and DMARC compliance alerts keep your team informed before deliverability issues impact campaigns.
Monitor your sender health score hourly. When reputation drops below your threshold, MailOdds posts an alert to your ops channel with bounce rate, complaint rate, and authentication health details.
// n8n Function Node - Sender Reputation Alert for Slack
// Schedule: Every hour via n8n Cron trigger
// HTTP Request: GET https://api.mailodds.com/v1/sender-health
const health = $json;
// Only alert if reputation drops below threshold

{ type: "mrkdwn", text: "*Bounce Rate:* " + (health.bounce_rate * 100).toFixed(1) + "%" },
{ type: "mrkdwn", text: "*Complaint Rate:* " + (health.complaint_rate * 100).toFixed(2) + "%" },

}MailOdds monitors 50+ DNSBLs for your sending IPs. When a listing is detected, post the details to Slack so your team can begin remediation immediately.
// n8n Function Node - Blacklist Detection Alert for Slack
// Trigger: MailOdds webhook or scheduled check via GET /v1/blacklist-monitors
const monitors = $json;
const listed = monitors.filter(m => m.listed === true);
if (listed.length > 0) {
return {
blocks: [

text: "*" + listed.length + " blacklist(s) detected:*\n" +
listed.map(m => "- " + m.blacklist_name + " (" + m.ip + ")").join("\n")
}
}
]
};
}Track DMARC alignment trends daily. When SPF or DKIM failure rates exceed your threshold, alert your team with domain, failure percentage, and pass counts.
// n8n Function Node - DMARC Failure Alert for Slack
// Schedule: Daily via n8n Cron trigger
// HTTP Request: GET https://api.mailodds.com/v1/dmarc/domains/{domain}/trend
const trend = $json;
const latest = trend.data_points[trend.data_points.length - 1];
if (latest && latest.fail_percentage > 5) {
return {
blocks: [
{
type: "header",
text: { type: "plain_text", text: "DMARC Failure Alert" }
},
{
type: "section",
fields: [
{ type: "mrkdwn", text: "*Domain:* " + trend.domain },
{ type: "mrkdwn", text: "*Fail Rate:* " + latest.fail_percentage + "%" },
{ type: "mrkdwn", text: "*SPF Pass:* " + latest.spf_pass_count },
{ type: "mrkdwn", text: "*DKIM Pass:* " + latest.dkim_pass_count }
]
}
]
};
}After a campaign completes, post a summary to your marketing channel. See sent, delivered, opens, clicks, bounces, and unsubscribes at a glance with a direct link to the campaign dashboard.
// n8n Function Node - Campaign Summary for Slack
// Trigger: MailOdds webhook on campaign.completed event
const campaign = $json;
return {
