Emails per day
Open and click rates aren't shown here — SendStack doesn't have tracking pixels or link-wrapping yet, so there's no real data to report for those.
Webhooks
Get notified on delivery, bounce and complaint events.
Not built yet. Mock page — we already receive SES/SNS events server-side (webhooks/ses.js), just no customer-facing config UI.
Settings
Account and workspace settings.
Not built yet. Mock page — would hold account name, team members, danger zone.
