Analytics - subscriber.dev

Analytics gives a quick health check for an environment: how your list is growing, how many people opted out, and how many emails sent, failed or bounced. Or ask your agent: “How did sending go this month?”

subscriber analytics --days 7

curl "https://api.subscriber.dev/analytics?days=7" -H "x-api-key: $KEY"

What the numbers mean

--days (1 to 365, default 30) only changes the two “in period” counts. Everything else is all-time.

Number	Meaning
Subscribers	Everyone in the environment, opted in or not.
New in period	Subscribers added in the last `days` days.
Opted out	Subscribers who are opted out of email.
Opted out in period	Subscribers who opted out in the last `days` days.
Sent	Emails and webhooks handed off successfully.
Failed	Steps that failed after three tries. See Troubleshooting.
Skipped	Steps deliberately not sent, such as to opted-out subscribers. See Troubleshooting.
Pending	Steps waiting for their delay.
Bounced	Emails your provider couldn’t deliver, split into hard and soft.
Success rate	Sent ÷ (sent + failed). Skipped steps don’t count against it.

What to watch

Bounces: a hard bounce rate above about 2% hurts your sending reputation. Clean your list, and use a provider that suppresses bounces automatically.
Opt-outs in period: a jump after a broadcast means it went to people who didn’t expect it.
Failed: anything above zero usually means a provider problem. Check the run’s reason.

Analytics doesn’t track opens or clicks.
